    I'm looking at replacing the flooring in an enclosed trailer. Many manufacturers use Advantech as an upgrade from 3/4 plywood. I've never worked with the stuff and was wondering about using it. I looked at their site and saw that there is a gap at the T&G for expansion. Since this is a trailer floor it is the actual floor, not a subfloor so i really didn't want gaps. Planned on painting the floor with epoxy paint.

    Expansion gaps as described are for large areas. An area the size of a trailer shouldn't need expansion gaps in the field, just at the perimeter. Cover the gaps with shoe mould.

    Doesn't look like a finish floor..... rather sub-flooring.

    Beeman,

    I've used Advantech in two different applications and it has worked extremely well in both applications.

    One was a large (3000 sq. ft.) addition to an existing house. We used Advantech for the sub-floor and covered all of the floor surface with hardwood. It's been installed for nearly 10 years and has no sign whatever of the hardwood pulling up or the sub-floor buckling.

    The other application is in an old house that had very rough, cupped, warped, gapped sawmill lumber for flooring. It had been painted many times and was peeling and was really nasty. I applied the Advantech over top of the nasty flooring and painted it using Porch and Floor enamel. As was stated, it looks like plywood. It does not look like a finished floor. However, it is very durable and functional and the homeowners are so satisfied with the function, they accept the appearance.

    Application is just like plywood.

    My understanding is that the major advantage of Advantech is the moisture resistance it provides. (such as in a house under construction that is rained on before being dried in) Part of this protection is the gaps you referred to that allow water to drain down through it instead of pooling and causing the joints of the subfloor to swell as you would have with standard 3/4" t&g OSB. If your application is going to be exposed to repeated moisture the Advantech might be worth it, if not, I would go with standard Tongue and Groove OSB. Hope this helps.

    Howdy.
    Is this for a travel trailer?
    If so, they are built frame floor walls etc. so check to see what probs you may face if you can't fit the new floor under the walls.
    I'd also be concerned about the extra moisture that they get exposed to and consider a treated plywood. Your can t/g it yourself by using a slot cutting bit with a router and make your own spline for the tongue.

    The floor in our home is all Advantech.

    I use it in my building business and it has become the standard for builders.

    This is an enclosed trailer 8'x28'. The frame is steel and the floor is screwd directly to the steel so the bottom is exposed to outside. It currently has 3/4" plywood for a floor but due to roof leakage the sides are rotted. The walls are 3/8" plywood and I've already stripped 1 wall and the ceiling because of the water damage.
    I've looked at the product at the lumber yard so I know what it looks like. Planned on garage floor epoxy for a finish. I guess my biggest concern was the gaps at the T&G and if they could be eliminated.

    If you want to do away with the joint just take a saw and cut the tounge and the groove off. I you are worried about water coming in if pulling the trailer at times when it rains just get some water proof construction glue that comes in a caulk tube and put a small bead in the groove before you put it down.

    Advantech is the real deal when it comes to sub floor that last. My brother has a piece that he uses for a cut table on his jobs. It stays on the trailer through rain and snow. It hasnt swelled or started to come apart any. Its been out in the weather for 8 years.

    Dont know your location but if you live where they use alot of salt in the winter I would wash the under side of the trailer every spring if you pull it in the winter time.

    We tried painting some Advantec and it did not work out so good. We used oil based paint but it bubbled in places. We tested another area with spray paint, just plain white spray paint and it did stick but did not look so good. We stopped and called the company and they said it was not made to paint.

    So - we stopped that idea and just nailed down plain pine planks instead. Looks good.

    Bought some Advantech and started to install it. Funny thing the sheets aren't 48", the sheet is 47 1/2 plus the tongue, The tongue is 1/2" so you lose a 1/2" every 4 ft., makes it odd spacing on the floor crossmembers.

    In most applications you run the 8' seam perpenducular to the floor joists so the difference is not important. Advantec is all we use for floor framing now - it's just the best material on the market for that application. Weighs a ton - sheeted a house with 1 1/8" Advantec a few years ago and it took two guys to carry a sheet.

    Just amazing how the industry standard of 4'x8' just gets cut so they can save a little.

    We painted the bottoms with porch and deck paint and it worked fine and covered well.

    That is amazing. I have been just assuming that my ability to build floor joists was messed. And all along it was the plywood at fault. I laid a sheet yesterday, but after reading this thread I measured the sheet to verify it's width. You right 47 1/2"

    That is messed up.

    But at least it means I was not messed up.

    No attempt to cut corners at all. It's all about standardization. The entire industry is set up to product sheet goods in 48" widths. Nobody is going to spend millions to modify production lines to produce a sheet an extra 1/2" wide solely for flooring use. The sheet is machined, creating the T&G AFTER it is manufactured in a 48" width. The finished product is still 48" wide including the tongue. I have been nailing subfloor down, everything from high dollar fir T&G plywood to commodity grade OSB, for three decades now, it's always been that way. Advantech BTW, is as good as it gets.
