I've been reading about epoxy and all the ways to seal plywood...has anyone ever used rubber roof coating or a product like this

Seems like an easy way to seal the exterior....would i need to worry about toxic fumes or off-gassing....? I plan to use spar varnish on the interior

I use the stuff all the time. It is a liquid and as far as using it on a curve, It would be very difficult to keep it from running.

Now I know anyone can put on paint without having it run but this stuff must be really piled on to give it a proper thickness.

Two coats? Nope It won't stick to itself. It'll look ok for a while but in 6-9 months the layers will separate. (I was told that its because of the hardener you have to add.)

And the fumes WILL kill ya.

I put the stuff on with a notched trowel then feather it out with a dry roller.

On anything other than a flat surface, your going to have problems.

All that being said...on flat surfaces its a great product.

Happy Trails

Thanks for the advice, good to know. I guess I'm just looking for an easy fix and was hoping this stuff might be it. I want to build a simple trailer with plywood sides and roof, no aluminum skin, and just paint it. I was hoping there was something I could just glop on and seal the exterior (I'm kinda lazy)

I used white pigminted mobile home roof coat to seal my motorcycle tear. 2 very heavy coats inside and out. It has sat outside for over a year now with no cover or shelter in the ice, snow and rain.

I coated it over 7/16 osb and its looks as good today as the day I coated it. I have crawled in it and rubbed up against it there is no chalking and it is thick enough it seals the joints between the wood members.

During the painting process I got a dab on my jeans. They have been thru the wash 30 - 40 times in the last 14 months and the dab is still there. Like Timex I guess " Takes a licking and keeps on ticking"

If simple is what you want why not try some of the newer house paints or porch paint. Some have a lifetime guarantee.

mho is you seal the joints first and use the coating to keep the damp out of the plywood. Nothing will make up for joints that are not sealed.

That said, you can use epoxy on the edges and that will keep out the weather. Then seal your plywood. :thumbsup:

It has been great except for the fact that the rubber is a dirt magnet
