Looking for advice: how do I waterproof wood (lemmy.world)

So I park my snow blower in the garage and would like the snow residue to melt in place and not go all over.

I built this giant tray with a ramp so I can push the blower on it, that way the snow will stay on the tray.

I will caulk the seams and paint it with some resistant paint but I'll like to either glue a tarp on it, or some other plastic material or perhaps use some special coating so it lasts a few years.

The "floor" of the tray is OSB (aspenite?). Not the best for this is what I had and this project is more of an experiment for me.

Any recommendations?

I've had some decent luck with teak oil, but I think you're wanting something a bit heavier duty. The most surefire way I can think of would be to coat it in a thin layer of epoxy. Beyond that, a good paint should also work well enough. Designing the geometry with water pooling in mind would also be a big help. Keeping the melt from staying in long term contact with a single spot will really reduce how effective you need the waterproofing to be in the first place.

Great idea!, I can easily add some feet for a gentle slant and poke a drain hole to go into a shallow tray on the side!!

Just make sure you take a little extra care with waterproofing the hole. If water leaches into the ply of the MDF, it'll rot it out from the middle before you even know what's happening. A little piece of plastic tubing going from the tray through the hole with some caulk to seal should do the trick. Put the end of the tube like 3mm below the surface of the ply to make sure water doesn't pool around it.
