A better plywood floor

Darkspeed · September 23, 2015, 10:36:37 AM

I found two un-inclosed trailer manufactures that use bare Advantec on their trailer decks, one of them is for transporting river rafts and these trailer sometimes get backed into the water. I think I am going to try it and I will report if there are any issues. However i still reserve the right to hate on regular OSB..

I bought a 16' flat bed trailer - the deck was 2 x 6 southern yellow pine - painted. Looked real nice, but didn't last 5 years. Replaced with pressure treated southern yellow pine, no paint or any other type of water repellant - 15 years later it is still solid.

I hope the advantech holds up as well - will be nice to have that as a suitable option. But not gonna hold my breath . . .

Ok. You guys convinced me. I'm using composite wood decking in my next bus.

Just move to AZ then you need to add water to keep it in good shape

I noticed that they spend a few sentences about how well they seal the edges. What if you have to cut off the edge to fit it? It is water resistant, not water proof.

What I was told is the entire panel is compressed at high pressure and the resin is waterproof and the chips are saturated in it before they are compressed so any pice is as water resistant as the whole.

If you're asking about the composite, it apparently has a very very low water absorption rate. Like waaay below typical wood. So yeah. Maybe seal the cut edge and sleep good

Just to mention that the water absorbability of wood depends upon the wood. Softwoods (fast-growing and therefore cheap and used in all these reconstituted products (chipboard, fibreboard, strandboard etc)) generally absorb water like a sponge and need special efforts to seal them. Hardwoods generally absorb water much less, and some hardwoods (eg. teak) are traditionally used in marine environments without even being coated. In fact teak is so naturally waterproof that the oils it contains prevent coatings from sticking properly. And yes, you can buy teak plywood, but you'd need to rob a bank first.

That's what I am talking about here in AZ we keep water in the sink to protect our Teak wood and it's not plywood then she uses some special oil once a year

I made the journey to Tampa to get my hands on some 3/4 T&G Advantech board today.

It has a very smooth surface with almost a plastic feel. There are no voids or depressions around the individual chips, it looks like resin and wood were compressed solid and then milled - i.e. you cant feel where the chips are. - so far so good

In defense of OSB: We put a 20 ft electric gate at the entrance to our property. The normal procedure would be to lay a concrete slab for the track for the gate to roll on. I got lazy (as usual) and just put down some painted OSB and mounted the track on that. The gate has 2 wheels about a foot apart. One is a grooved wheel that rolls on the track. The other is a solid rubber wheel that rolls directly on the OSB. So this board has been sitting in the desert through sun and storm for over a year and is still doing fine. How many years would it take as an floor underlay to equal that abuse?

Have you considered MDO (medium density overlay) or HDO (high density overlay)? MDO has been used for highway signs and HDO is used for concrete forms. MDO comes in single sided or double sided.

I'm going to resurrect this thread for future searchers. We have done months of research on Advantech and indeed it is the ultimate floor for a coach conversion bar none. We installed two layers of it with spray foam in between in our coach. It is basically lifetime waterproof. It isn't typical OSB and shouldn't be even discussed in the same category. They basically take the individual chips, pressed at high pressure with waterproof resin/glue and form the boards. Straight, flat almost laserlike edges. Absolutely amazing stuff to work with. A cut edge is as waterproof as a non cut edge. 500 day water proof guarantee. Literally, you can cut a piece, put it in a bucket of water for two years and it will not soak up any of the water. Awesome stuff.
