Vic Grizzle -- CEO
Thanks, Tom, and good morning everyone. It's good to be with you today to review our second quarter results and update you on several recent important developments. Second quarter results were solid with both sales and adjusted EBITDA up double digits. We had strong volume growth in both segments, we achieved solid like-for-like price increases to offset inflation and wave delivered a record quarter. Overall, our results in the first half of the year were solid and in line with our guidance. As we enter the busy summer period, we remain confident in our 2018 outlook.
Total company second-quarter revenue of $249 million was up 10% versus the second quarter of 2017, and adjusted EBITDA of $95 million was up 12%. Free cash flow was up 140% in the quarter, and year-to-date free cash flow has tripled to almost $100 million. The Architectural Specialties segment had another strong sales quarter with revenue of $42 million, up a strong 18% from last year. Adjusted EBITDA in the quarter of $9 million was up 5% resulting in a 22% EBITDA margin.
Architectural Specialties sales growth was broad-based with all major substrates up at least 15% including metal, wood, and the Technum products. Big projects continue to provide tailwinds to the businesses. We completed the Salt Lake City Airport renovation in the quarter, and our pipeline of large jobs remains strong and includes major transportation projects at LAX, the Royal Caribbean terminal in Miami, and the Grand Central Station among others.
Architectural Specialty margins compressed in the quarter due to the timing of investments in selling and design capabilities, and the mix of products sold in the quarter. That you will remember we've discussed that we can see some quarter-to-quarter variance in our results due to the timing of investments and project work.
Overall, this business continues to gain momentum, and grow significantly faster than the underlying market. For the full year, we expect sales to be up more than 15%, with adjusted EBITDA margins better than 2017. During the quarter, we also completed a strategic acquisition within the Architectural Specialties segment, the purchase of Plasterform. The purchase of Plasterform provides us with the manufacturing and selling capabilities for ultra-expressive, custom architectural cast ceilings, and walls, and other items. Plasterform's unique capabilities and process technology allows for intricate three-dimensional design options.
A level of detail and dimensionality that is not possible with our current portfolio. As with the Techtum acquisition, we will bolt these capabilities onto the Armstrong platform and combine them with our sales, distribution, and operations expertise to grow even faster and enhance their profitability. Now additionally, as you have seen in our press release today we just reached an agreement on another Architectural Specialties acquisition.
We will be purchasing Steel Ceilings Incorporated, thereby adding additional capability and capacity to our metal ceilings product line. Steel Ceilings is a manufacturer of standard and custom metal ceilings including architectural, radiant, and security ceiling systems. We look forward to closing this transaction later in the quarter, and adding this business onto the Armstrong platform.
Now, turning to the Mineral Fiber segment, second-quarter revenue of $207 million was up 9% from last year. Adjusted EBITDA on the quarter of $86 million was up 13% from 2017, and EBITDA margins expanded 160 basis points to 41.5%. Mineral Fiber volume was up 5% in the quarter. As we previewed on our last earnings call, we had a strong April as shipments rebounded from weather-related issues in March. Now, without the benefit of the Q1 delay, volumes would have been up about 3%. Sales to Latin America, Canada, and the U.S. Home Centers were particularly strong in the quarter. Overall, a solid volume quarter for Mineral Fiber.
AUV, which again is a combination of like for like pricing and product mix was up 4% from prior-year as pricing gains accelerated from the first quarter, and mix continues to benefit from our new high-end products. Sales of our more recent product innovations that we've been talking about total acoustics and sustain grew double digits in the quarter. Mineral Fiber segment EBITDA benefited from the higher volume and solid realization offsetting inflation in the quarter. Manufacturing productivity improvements continue, but were tempered by headwinds related to the St. Helens plant closure.
Brian will provide more details on this when he discusses our financial results in a moment. But we've had a strong quarter as multiple pricing actions have gotten us business back in line with the significant steel cost inflation expanding margins very nicely. Wave equity earnings grew 22% a quarter. Now operationally in our Mineral Fiber business, we continue to make good progress on our key initiatives. The flexible design line at Marietta is ramping up production and is on schedule. We completed the closure of our St. Helens Plant ahead of schedule and have begun decommissioning activities. The St. Helens production was picked up by other manufacturing facilities, and customer service was maintained throughout that process.
Our new distribution center in Phoenix launched operations and it's now providing improved service levels to our customers on the West Coast. We've largely completed our G&A restructuring, which along with our other restructuring activities will provide $9 million of cost tailwinds as we move into the second half of 2018. In June, we formally launched Design Flex Ceiling Solutions at the American Institute of Architects Expo in New York, the largest architectural show in the U.S. with over 26,000 in attendance. Design Flex gives architects and designers the freedom to reinvent ceilings by mixing and matching shapes, sizes, and colors.
Our manufacturing investments including the flexible Design Line Marriott, are providing mass customization solutions at standard lead times. This means, minimum orders as small as one carton can be shipped to the job site in just three weeks. Industry-leading capabilities in both product and service. The response to our launch at AI was overwhelmingly positive from the new shapes, sizes, and colors, to the innovative technology we used to showcase design flex. Post-show, we received recognition as the most innovative commercial product out of more than 800 companies exhibiting.
The AA Booth and Design Flex will both be on display at our investor day in November. With regard to the sale of our EMEA and Pacific Rim businesses, you likely noted from the 8K we filed last week, that we've amended the terms of our sale to Knauf. The purchase price of $330 million remains unchanged, and the amendment assures our unconditional receipt of the cash in a timely manner. Knauf will now make a fully nonrefundable payment of $250 million to Armstrong on August 1st, and $80 million on September 15th. With this amendment, we continue to expect net cash realized from the transaction to be $250 million, the same as we estimated when we announced the sale.
In light of the ongoing competition clearance process, we now expect closing to occur prior to year-end. As we've mentioned before, it has been our intention to return a majority of the net cash realized to our shareholders, and I'm pleased to announce that to enable these actions, our board has expanded our share repurchase program by $300 million to a total of $700 million. Management and the board are working on finalizing the vehicles and the timing for executing these repurchases. And with that, I'll pause and turn it over to Brian for a deeper dive into our financial results. Brian.
Brian MacNeal -- CFO
Thanks, Vic. Good morning to everyone on the call. Today I'll be reviewing our second quarter in year-to-date 2018 results. But before we go into the financials as a friendly reminder, I'll be referring to the slides available on our website. Slide three details our basis of presentation. Turning to Slide four for our second quarter results, sales of $249 million were up 10% from the second quarter 2017. Adjusted EBITDA increased 12% and margins expanded 70 basis points. Adjusted diluted earnings per share were up 16%, aided by our share repurchase program. In the second quarter, we repurchased 620 thousand shares for $35 million.
Since the inception of our repurchase program in the third quarter of 2016, we've bought back over $4.7 million shares for roughly $230 million at an average price of just over $48 per share. Adjusted free cash flow improved by $39 million were a 140% over the prior-year quarter due primarily to improved working capital performance in the quarter. Net debt increased by $21 million as cash balances are lower than last year and debt is also lower. Turning now to slide five, adjusted EBITDA increased $10 million as volume gains in both Mineral Fiber and AS flowed to the bottom-line. AUV was positive and offset inflation.
Input costs include $2 million of inflation as well as other spending primarily related to free costs associated with our change manufacturing and distribution footprint. SG&A increased due to investments in AF capabilities and legal costs in the mineral fiber business. WAVE had an excellent quarter as profitability was up 22%. Slide six shows our change in adjusted free cash flow which grew $39 million compared to the prior year quarter. Working capital improved by $18 million year-over-year, with onetime items in both the base period and current year impacting the results.
Capital expenditures were lower as we have returned to a more normalized level of capital investment and Wave earnings improvement flow through to cash. The other category improved due to the timing of tax payments. Slide seven begins our segment reporting. In the quarter mineral fiber sales grew 9% with all three drivers, volume, like-for-like pricing and mix improved versus 2017. Adjusted EBITDA was up $10 million. The volume impact on EBITDA is straightforward. Put fall-through of mix was later than usual driven by channel mix.
The strong sales growth we experienced in Latin America and the home centers benefited us on the volume line. But was a slight offset to the mix line as the margins earned in these channels is lower than the overall segment. The manufacturing and input cost line captures ongoing productivity gains at our plants offset by freight and raw material inflation, as well as, the freight costs associated with reconfiguring our manufacturing and distribution footprint due to the closure of the St. Helens Plants. SG&A was higher in the quarter largely due to legal expenses including those associated with M&A and litigation matters. Wave equity earnings increased $5 million or 22% versus prior year.
Moving to our Architectural Specialty segment on slide eight, quarterly sales increased 18% as Armstrong's broadest specialty ceilings in malls portfolio coupled with our superior service and support capabilities continues to drive increased penetration in this market. Adjusted EBITDA in AIS was up 5%. Margins contracted as we made investments in manufacturing and SG&A to drive and service future growth. Year-to-date adjusted EBITDA margins of 22.7% are up a 170 basis points versus the first half of 2017. Slide nine recaps our year-to-date results. Sales of $476 million were up 7% from the first half of 2017 and in line with the high end of our guidance range.
Adjusted EBITDA increased 9% and margins expanded 60 basis points. Adjusted diluted earnings per share were up 13%. Adjusted free cash flow has tripled from last year driven by working capital gains and lower capital expenditures. Slide 10 is our total company EBITDA bridge for the first half of the year. Volume, price and mix are all contributing to improve profitability. Input costs including the extra freight activity in the second quarter are a headwind. Productivity in our plants is running $3 million ahead of last year even as we ramp up new products, capabilities, and consolidate production. Wave earnings are up $3 million. Year-to-date Wave has delivered price over inflation.
Finally, we add back stranded international costs of $4 million. Slide 11 shows year-to-date free cash flow. Improvements in working capital including the 2018 receipt of environmental insurance recoveries and lower capital expenditures helped drive the $66 million improvement. Slide 12 updates our 2018 guidance. Our revenue adjusted EBITDA and adjusted free cash flow guidance are all unchanged from our initial guidance. We've increased our revenue growth expectation in Architectural Specialties by 500 basis points. We are increasing the adjusted EPS range $0.07 to reflect our share repurchase activity to date. We now anticipate EPS growth of 19% to 27%. Note that our share count for EPS calculation is our most recent position and does not take into account future share repurchases.
To close, I'm pleased that we're able to execute on the acquisition in the quarter and announce another one here on our earnings call. For modeling purposes both companies will be purchased for a little over $11 to $12 million range. Combined in 2019, we expect them to have just over $20 million in annual sales and will contribute in 2018 about a million dollars to our bottom line. Margins for both businesses will ramp up toward the overall AS segment margin.
Similar to what we've achieved with Techtum. Our businesses are building momentum and I look forward to a strong third quarter as we're lapping a soft comparable period on the top line and expect strong bottom line performance as well. We're on track to deliver our annual guidance of 5% to 7% top-line growth and EBITDA growth of greater than 10% and I'm confident that we have the plans in place to deliver. With that, I'll turn it back over to Vic.
Vic Grizzle -- CEO
Thanks, Brian. 2018 is on pace to be a record year here at AWI. The strategic initiatives and advanced manufacturing investments we've talked about are bearing fruit. As an America's focused ceilings and specialty wall company, we have been investing to extend our leadership position, both product solutions and support services. We're already achieving success with total acoustics and sustain products. Now with the formal launch of design flex, we're further extending our leadership into next-generation interiors-based solutions and reinvigorating the mineral fiber ceilings category and our innovation pipeline has never been better.
The Architectural Specialty business continues to hit on all cylinders. We're driving impressive organic sales growth, expanding margins as we get better at executing in the specialty space and we're winning and delivering iconic projects. Adding three strategic acquisitions in the past 18 months at a Robust M&A pipeline, and this is not only a great business today, but it has an exciting future as well.
We just completed a review of our three-year strategic plan with our board of directors and I have said the alignment and the confidence has never been higher. This confidence is clearly demonstrated in the expanded repurchase authorization that I mentioned earlier. The cash generation of this business is unique, and we will continue to deploy it, to invest in our business, to acquire bolt-on acquisitions and return it to our shareholders. So thanks again for being with us today and with that, I'll open it up to questions.
Questions and Answers:
Operator
Ladies and gentlemen, if you have a question at this time please press star and the number one on your touch-tone telephone. If your question has been answered or you wish term if yourself from the queue, please press the pound key. Our first question comes from the line of Stephen Kim with Evercore ISI, your line is open.
Stephen Kim -- Evercore ISI -- Analyst
Yes, thanks very much guys, I appreciate the color. Was curious if you could talk in the middle of fibers business, I think you're talking about the zero to two in terms of the volume for the year, but we had a little bit of volatility in the first six months, you talked about that in terms of the 1Q in April and so forth. So, I was curious if you could talk a little bit about what you saw in July and whether your expectation would be that you could be in a 0% to 2% range in each of 3Q and 4Q, as well as, for the year.
Vic Grizzle -- CEO
Yes, Stephen, this is Vic. Going back first to the volatility that we talked about right from March to April based on weather. So when you look at the first half, were in that zero to two range that were out looking for the whole year. So, that coupled with the market conditions that we're seeing into the third quarter and what we expect to see the rest of the half or rest of the second half, which is very consistent with the first half frankly, we remain confident in that zero to two outlook that we provided for Mineral Fiber.
Stephen Kim -- Evercore ISI -- Analyst
That's great, helpful. Then if we could talk a little bit about in the slide I think you made reference to Lat Am and Home Centers having an impact on terms of lower mix but also higher volume, was curious if you think this is going to be an ongoing trend that we should be factoring in any way or if it was primarily a 2Q phenomenon?
Brian MacNeal -- CFO
Yes really, it's been predominantly a first half phenomenon. I would say in the first quarter we also saw and we spoke to this our Lat Am, and in particular, in the Puerto Rico area we called out based on some of the rebuilding that's going on there. So, I expect that to continue. I think the sales through the Home Centers is a bit of an indicator on some of the R and R activity that we're seeing broadly in the market.
So we would expect that to continue. As you know, with the home centers you can get some lumpiness quarter-to-quarter based on their inventory adjustments as we've talked about in the past. But the sell-through that we're seeing through those home centers, we expect to continue into the second half.
Stephen Kim -- Evercore ISI -- Analyst
Great. Okay thanks very much, guys.
Vic Grizzle -- CEO
Yes, thanks, Stephen.
Operator
Our next question comes from the line of Nishu Sood with Deutsche Bank, your line is open.
Nishu Sood -- Deutsche Bank -- Analyst
Thank you. So obviously, great sales trends in Architectural Specialties continuing acquisition, the acquisition pace has stepped up here as well. As we look across the initiatives you have going in Architectural Specialties, the three you've made over the last two years here plus the flex form, is there a broad strategic overlay that you can guide us to that's guiding these acquisitions or should we think about them more as this is opportunistic, there's obviously an incredible array of specialties and ceiling materials and it's more opportunistic as you fill in your product portfolio?
Vic Grizzle -- CEO
Yes. Good question Nishu. I think the strategic overlay -- let me separate. The two that you mentioned were the Design Flex which is really a mineral fiber initiative to reinvigorate that category from a two-by-two white side down ceiling tile to shapes, colors, and sizes that can really, I think, reenergize what architects want to design around. So that is separate from the Architectural Specialty. So let me just talk about that for a second because I think this is the feedback that we got from the AIA show, and the initial launch into the marketplace is very exciting. It's very encouraging that we're over the right target and what architects want to do with that space going forward. So they want the aesthetic, they want the statement that comes from the ceiling plane, but they also need the acoustics. This is a great combination of capabilities for architects to design around. So we're very encouraged by that, and again, the strategic overlay for Design Flex is to drive Mineral Fiber sales growth. So, that's the -- one of the initiatives that's going to support that.
On Architectural Specialties, these are really adjacent capabilities that we don't have in our portfolio today that we want to augment what we currently take the market to broaden the basket of solution capabilities to help architects with a one-stop-shop approach to solve all of the spaces within the commercial buildings. It's a very fragmented space, as we've talked about in the past.
So, the best way for us to get this capability is to acquire this capability, as it exists in the marketplace today, and then bolt it onto Armstrong's capabilities and specifications skill sets to get these products speced.
So again, there's two strategic overlays here, grow the mineral fiber business through Design Flex and creating more options around next-generation design requirements from architects. No.2 is to add to the product capability in Architectural Specialties through bolt-on acquisitions to play in more spaces within the commercial buildings, and that's really what's driving our -- we're being very purposeful about adding unique capabilities to the portfolio. Not all the capabilities, but the unique capabilities to the portfolio, again, leveraging Armstrong's scale and our ability to go-to-market.
Brian MacNeal -- CFO
Nishu, just real quick to add to that, Vic mentioned that we're being purposeful and we are. As you know, we have a good balance of make versus buy in this business, and the AS business drives over 50% ROIC. So, we're very purposeful in our M&A to make sure there are unique capabilities that stand out.
Nishu Sood -- Deutsche Bank -- Analyst
Got it, got it. Thanks, I appreciate the call in there. Second question, Brian, you called out transportation expenses as a result of the reconfiguration of your distribution network with the shutting of the West Coast facility and the distribution center being opened. Should we take that as one-off expenses related to the plant closure and the transition to the distribution center? Or are these more ongoing as a result of the new layout? Obviously, there's been pressure on freight expense. How does that play into the picture as well?
Brian MacNeal -- CFO
Sure. So, I called out both the freight inflation, which is ongoing, but the onetime nature of the extra transportation and extra cost we experienced in the quarter, was really around the closure of St. Helens. As we moved that production into our other plants, at the same time demand increasing, we saw some additional overtime related to that and some additional transportation. So, there are more onetime in nature. We're all facing that freight inflation as a separate item.
Nishu Sood -- Deutsche Bank -- Analyst
Okay. Thank you.
Operator
Thank you and our next question is from Michael Rehaut, with J.P. Morgan. Your line is open.
Elad Hillman -- J.P. Morgan -- Analyst
Hi, this is Elad on the line for Mike. I just had a couple. So first, on Architectural Specialties, how big do you guys see the segment getting over the next three to five years? How much of that is going to be organic versus inorganic, and I presume that the raised guided greater than 15% versus greater than 10% is mostly organic, but maybe if you could diagnose the inorganic, sorry. But, if you could just break that down for us a little bit.
Brian MacNeal -- CFO
Well, in Architectural Specialties, we've experienced in the first half solid double-digit growth. In fact, it's up 20% organically. So, we're seeing some very nice market penetration activity there and some good traction in the new project pipeline that we've been executing against. So, we expect that to continue and what we're out looking in that business, and I think what you can expect in that business is that we should have doubled, solid double-digit organic growth.
Then, as we add somewhere in the neighborhood of one to three bolt-on acquisitions in this space a year to further accelerate on top of the double-digit growth inorganically. So, it's hard to predict what those inorganic opportunities and the timing of those, so it's really tough to answer your question very directly on that. But, the plan and the play that we're running around that is, continued solid double-digit on organically, winning these projects and servicing those.
Again opportunistically, adding those targeted bolt-on acquisitions that add to the capabilities that we need going forward. Again, for arranging standpoint somewhere between the ranging $10 million to $15 million in size as a typical acquisition in this space.
Elad Hillman -- J.P. Morgan -- Analyst
Okay. Thanks. To follow-on on that just to get a little more clarity around margin potential going forward, do you see a lot of potential for the margin architectural to expand beyond where they currently are?
Brian MacNeal -- CFO
Yes, we expect to, again a lot of these companies are not as profitable as our base business, and so as we add companies to this, we plan to expand and improve their margins. At the same time, and as we've demonstrated. If you look back over the last couple of years, at the same time we're getting more efficient and we're getting better at servicing this specialty space and we're improving margins. I would expect that to continue for us in the next several years.
Elad Hillman -- J.P. Morgan -- Analyst
Okay. Thank you.
Brian MacNeal -- CFO
Thank you.

Our next question comes from the line of John Lovallo with Bank of America, your line is open.
John Lovallo -- Bank of America -- Analyst
Hey, guys. Thank you for taking my call. First question is I just want to make sure I'm understanding this correctly. So, mineral fiber volume in the first quarter was down 5% year-over-year and then I think you guys mentioned on the last call that April was enough to kind of flatten the volume out for the year, so I guess up 5%. So, it seems to imply that all of the 5% volume in the second quarter they reported today was April. I'm not sure if I'm understanding that correctly, so I guess the question is were May and June flattish? Then what are you seeing in to July? Thank you.
Brian MacNeal -- CFO
Yes. I mean to answer your question very directly as I said in my prepared remarks, that without the overflow from March into April, which we spoke about that in April, volumes were up in the quarter 3%. So, we had positive volume growth throughout the quarter.
John Lovallo -- Bank of America -- Analyst
Okay. Got you. Then maybe as a follow-up here, the $9 million of SG&A savings in 2018 was that, maybe I heard this wrong, was that lowered, was that $10 million previously and the target heading into 2019, is that still $10 million?
Brian MacNeal -- CFO
You're done. So, what we said, for the full year it's going to be 10, 90 of that's in the back half, it's more than just SG&A just for clarity, as its total restructuring savings that it's both manufacturing and SG&A. Next year, we expect another 10 which will bring the full program to the high range of 20.
John Lovallo -- Bank of America -- Analyst
Okay. Thank you, guys.
Thanks, John.
Operator
Thanks for calling me. I'm sorry, our next question is from the line of Kathryn Thompson with Thompson Research. Your line is open.
Brian Biros -- Thompson Research -- Analyst
That is Brian Biros on Kathryn Thompson. Thank you for taking my questions. I wanted to ask about the Steel Ceilings acquisition announced this morning. If you had any idea of the total addressable market for the Steel Ceilings products and then specifically for the Steel Ceilings company, where do you think that might go in the next two to three years on growth?
Brian MacNeal -- CFO
The Steel Ceilings is an exciting acquisition for us. They bring some additional capability that we don't have in the portfolio today, especially around radiant ceilings and security ceilings. For presence, for our example or other institutions. So, there's some real exciting products and capabilities that will be additive to our overall capability.
They also bring some of the other basic capacity that we currently have but it's added capacity for us to serve this market. We've not broken out exactly how big the specific metal ceilings market is but it's part of a billion-dollar market opportunity that we're targeting in the specialties market here in North America. So, you can look at our sales in this category and know and recognize that we've got long ways to go to reach more significant market share level. So, lots of room to grow here and we're excited about the acquisition.
Brian Biros -- Thompson Research -- Analyst
Got you. A quick follow up on that. Did they have a national sales footprint or are they more regionally focused in certain parts of the Americas?
Brian MacNeal -- CFO
They are a national organization. They use a combination of indirect and direct and again, this will be a great opportunity to bolt this capability and merge that into Armstrong's national sales organization. So, that's our plan to do that, to really leverage this capability.
Brian Biros -- Thompson Research -- Analyst
Got you. Thank you.
Brian MacNeal -- CFO
Yes. Thanks, Brian.

Our next question is from the line of Phil Ng with Jefferies. Your line is open.
Maggie -- Jefferies -- Analyst
Hey guys. This is Maggie on for Phil. [inaudible] mineral fiber volumes, can you quantify the impact from the extra shipping day in the quarter? Also, if there was any pre-buys in the tile business or the wave JV. Thanks.
Brian MacNeal -- CFO
I'm sorry Maggie, I didn't catch the first part of the question.
Maggie -- Jefferies -- Analyst
I'm sorry. Could you quantify the impact from the extra shipping day in the quarter?
Vic Grizzle -- CEO
Would you want to take that Brian?
Brian MacNeal -- CFO
Sure. So, Maggie, we've said in our prepared remarks about a point-and-a-half, we rounded that to the timing of what shipped in Q1 into Q2 and from a pre-buy standpoint.
I'd say, minimal pre-buying at all on the Mineral Fiber side. A little bit more on the WAVE side given that the number of price increases we've done but very minimal on the mineral fiber side.
Maggie -- Jefferies -- Analyst
Got it. Just a quick follow-on, I'm curious if you're seeing any signs that trend in shipments for Mineral Fiber is accelerating given the strong economy and maybe any benefits from corporate tax cuts, thanks.
Brian MacNeal -- CFO
Yes, the overall market has improved, there's no question about it. We outlook and improve market at the beginning of the year and we're experiencing a better market environment than we had last year. So, we are in a more positive market. When you look at some of the stats going around, the value put in place, for example, is positive really in all the segments, transportation, in particular, has been particularly strong, based on sturdy activity in 2017.
So, there's some, I'd say, solid activity, I've been in the marketplace in the last four months several times talking to both contractors, and distributors, architects, everybody is very busy and their backlogs are strong. A lot of them are saying it's not been this strong in a long time, so I think there's a lot of good activity out there, we're experiencing I think the market that we expected in which is really nice. Thanks for the question
Maggie -- Jefferies -- Analyst
All right. Thanks guys.

Our next question is from the line of Justin Speer, with Zelman & Associates, your line is open.
Justin Speer -- Zelman & Associates -- Analyst
Just wanted to tease out the guidance of 345 and 360, what was the incremental acquired EBITDA that will be in that number or is that the right way thinking about it in the 345 or 360 is including the incremental M&A?
Brian MacNeal -- CFO
Justin it'll be, I mentioned in my prepared remarks, just about $1 million would be the impact of the EBITDA for the acquired business.
Justin Speer -- Zelman & Associates -- Analyst
Thanks. Perfect, and thinking about the multiples paid on EBITDA, what did you pay for those assets on EBITDA if you can characterize that and also just in terms of the competitive landscape on the M&A side with other entrants maybe getting into the space, maybe you characterize what you're seeing on that front? When you're looking at your funnel.
Brian MacNeal -- CFO
Yes. So, obviously we look at both pre and post-synergies but given the value that we bring to these acquisitions and the capabilities they bring to ours, both of these are in that typically they are seven to eight multiple post synergies. So, we mentioned roughly $24 million of purchase price, we expect that $20 million of sales next year and we expect these margins to, but they're currently reported low in their own internal private businesses, but they'll start to expand like we've seen in takeoff and get close to that AS overall margin of 22%.
Justin Speer -- Zelman & Associates -- Analyst
Excellent. On the M&A side, are you seeing any competitive incursions on the M&A side that are changing economics at all in your models of these candidates?
Vic Grizzle -- CEO
Yes. Sorry Justin, this is Vic. So, on that front, there's not really a significant change on the competitive aspects of these acquisitions. In fact, several of the acquisitions they're not in a process and so we've had a direct conversation and had a direct process with them. So, with that said, a lot of these companies are growing nicely and they're benefiting from an improved market condition as well. So, that's part of the conversation I think their current state and their future outlook as we negotiate with these companies. But again, I would say there's nothing material to talk about in terms of a change in the competitive landscape around M&A.
Justin Speer -- Zelman & Associates -- Analyst
Last question for me and just these proceeds that are coming from the asset sales, it looks like you're going to be I guess the placeholders is for buyback? Have you guys considered a special dividend or any other revenue, I know you have M&A obviously in the hope of buybacks but is there even though maybe potential for a dividend on top of that?
Vic Grizzle -- CEO
Again, back in November when we signed this agreement with Knauf to sell our international assets, we had indicated that point it was our intention that we would return a majority of this to shareholders. So, we're still on that path to do that and we've had a lot of time to think about all the options. So, I think you've identified the vehicle at least that we plan to move forward with and returning at these proceeds. But with that said, longer term, a balanced approach to shareholder return is our goal and we plan to keep that in view.
Justin Speer -- Zelman & Associates -- Analyst
I appreciate it guys.
Vic Grizzle -- CEO
Thank you.

Our next question is from the line of Ken Zener with KeyBanc, your line is open.
Ken Zener -- KeyBanc -- Analyst
Good morning everybody.
Vic Grizzle -- CEO
Hi, Ken.
Brian MacNeal -- CFO
Hi, Ken.
Ken Zener -- KeyBanc -- Analyst
Hey, Vic, question here I was just looking at your last deck. Can you give us some reference point where we are in 2018 versus kind of the peak that we had in, I guess, that was '06 or whatever? What's the percentage that we're down in volume for your mineral wall business or the industry, however you want to think about it?
Vic Grizzle -- CEO
Yes, volumes in the mineral fiber ceilings business -- and I would probably say across a lot of the building products spaces -- are still down in that 25% range in volumes.
Ken Zener -- KeyBanc -- Analyst
I know last year I think you had -- one of the things I've always asked you guys about is the office versus retail versus the education, transportation, and other categories, which is more cyclically depressed. But last year third quarter we had some issues related to education given that it's July. My kids are just going back to school in about 2.5 weeks. Can you comment if there are any comp issues relative that we should be kind of prepared for? I know you kind of guided that 0% to 2% for the year but because third quarter is outsized in education, is there any insight you can provide in terms of what you're seeing?
Vic Grizzle -- CEO
Yes, it's still early but I would say that it's better than it was last year, and you remember the story last year, Ken, that a lot of these states made midyear corrections to their budgets and diverted funds away from education, both K through 12 and higher education. So, we track that, by the way, and we can tell you that fewer states have made funding adjustments so far than they did last year, and that supports, I think, the better environment that we're seeing right now.
Ken Zener -- KeyBanc -- Analyst
Okay and then in the specialty architectural, was there something that -- I would have thought that going into generally new construction you'd had pretty good visibility. Was that revenue growth, I mean, that organic increase? I mean, or was the increase tied to the M&A? I know that EBIT contribution was a million for the year but was it that M&A led you to do that or you are actually just seeing a lot more business coming through? Sorry for the clarification.
Vic Grizzle -- CEO
Well, when you look at our first half, Ken, we're up 20%. So, we've had a stronger first half. The project pipeline is filled up very nicely, and the teams are executing against that wonderfully. So, it was prudent for us to, and we do have visibility. When you look at our backlog and our pipeline, we do have pretty good visibility to what's going to happen in the second half. So, that gives us confidence to go ahead and raise the top line guidance in that business.
Ken Zener -- KeyBanc -- Analyst
Good. Congratulations.
Vic Grizzle -- CEO
Thank you very much, Ken.

Our next question is from Judith Merrick with SunTrust. Your line is open.
Judith Merrick -- SunTrust -- Analyst
Yes, this is Judith for Keith Hughes. Thanks for taking my call. Just one more follow up on the Architectural Specialties business on the margin. You called out the timing of the selling expenses and some of the investments that you're making. Will there be anything else that kind of stands out maybe in the base business or was your manufacturing costs in line with what you anticipated?
Vic Grizzle -- CEO
Yes. There's two things really. We talked about the timing of some of those expenses, and they can be lumpy as we feather them in. We've had a history for the last five years of doing, I think, a good job overall on a year-to-year basis of feathering in support resources that fall into SG&A, but it's a lot of designers and CAT operators and project managers, and we feather those in to support future growth at a rate and pace that allows us to grow with the business and expand margins. So, quarter-to-quarter, you can get a little bit of lumpiness on that and that's what we're seeing.
The other thing that we saw in the second quarter, and we can see this again quarter-to-quarter, is your mix can change a bit based on project activity. We saw a little bit of a headwind from the mix in the Architectural Specialty business in the second quarter. So, a lot of that just kind of works its way out over time throughout the year, which gave us the confidence again to say top line is going to be better than we thought and we're going to expand margins in that business in 2018.
Brian MacNeal -- CFO
Just to add a little bit more to that, we came in -- at Q1 AS had a margin of 24%. Last year, it was 22%, and we made a point on the call that we're going to see some of that lumpiness. Then, in Q2, we are at 21.5%. We expect the full year to be above that 22% we delivered last year, but we will get some movement in between quarters.
Judith Merrick -- SunTrust -- Analyst
Okay. Great. Thank you for the clarification.
Vic Grizzle -- CEO
Thank you.

Once again, ladies and gentlemen, if you have a question at this time please press star and the number 1. Our next question comes from the line of Garik Shmois with Longbow Research. Your line is open.
Jeffrey Stevenson -- Longbow Research -- Analyst
Hi, this is Jeff Stevenson in for Garik. I just had a quick question on tariffs. I was just wondering how we should be thinking about inflation over the rest of the year and what actions do you think you'll have to take, if any, with your supply chain?
Vic Grizzle -- CEO
Yes Jeff, this is Vic. So, on the tariffs, the major impact for Armstrong's business is around steel. Our grid systems are obviously very dependent on steel supply. We do import some steel internationally. We've been talking about this quite regularly over the last six months. So, the actions that you're asking about are the price passing along these tariffs and the higher steel costs onto customers through price increases.
We've executed a number of them already this year. So, we're already responding to the tariffs and the inflation. Some of this inflation will continue to linger, we believe, in the second half and we're poised with another price increase in August to make sure that we're staying out in front of that. Again, I'm pleased to report in the second-quarter, the pricing actions that we talked about in the first-quarter have materialized in good price over inflation in the quarter. So, we're going to continue to run that and stay ahead of inflation as we've done for many years now.
Jeffrey Stevenson -- Longbow Research -- Analyst
Okay. Great. Thank you. Then, just a quick question on your guidance. How should we be thinking about the mix impact and your AUV guidance for this year?
Brian MacNeal -- CFO
Yes. Jeff, this is Brian. We've incorporated any potential mix headwind in that guidance of three to four.
Jeffrey Stevenson -- Longbow Research -- Analyst
Okay. Thank you.
Vic Grizzle -- CEO
Great. Thanks, Jeff.
Brian MacNeal -- CFO
Thanks Jeff.
Operator
Thank you and I'm not showing any further questions. So, I'll now turn the call back over to Vic Grizzle CEO for closing remarks.
Vic Grizzle -- CEO
Great. Thanks everybody for being with us today. Again, we are on track to deliver a strong year in 2018, very encouraged by our board's vote of confidence to authorize an additional $300 million of share repurchases. Again, we're excited about second half and we appreciate everybody's attendance today. Look forward to talking to you next quarter.
