[aggie79]

Has anyone tried this for waterproofing the underside of your trailer deck?

I've used this and similar materials from Grace in construction for weatherproofing and have had excellent results. It is fairly easy to apply to a flat surface. It is not intended as an exterior surface, so that may be an issue. It is also not cheap.

Used it over my hinge area it is good stuff. I have seen it applied to roofing plywood and some one got it crooked tried to remove it and it took the first ply of the plywood off with it. I think it would be great but you are right kinda $$$$$

Yeah, I should have also mentioned the part about you better have it in the right place when you install it. I've removed plywood decking instead of trying to wrestle peeling this stuff off.

I used fibered roof coating $6 a gallon and used a $1 store squeegee to apply it. That looks like good stuff but I wonder how it will hold up underneath over the years.

I used fence paint from Tractor supply,it's a asphalt based paint,it dries hard and it's been on about 3 years and seems to be doing good.Bill
