Can laminate countertops be waterproofed for outdoor use?

[Kaido]

make your own surface with liquid casting resin? it'll be flat AND level without needing to shim.

Though, you move that cinder block 1/4" and it won't be level any more.

Yeah, I've used Envirotex on some projects (the same stuff they use on bar countertops for like 1/8" clearcoat, basically just a 2-part epoxy).

Concrete is in the back of my head, but I'd have to do more work to make it permanent so it'd be part of the patio when I move out.

4x8 sheet of marine plywood. Stain, seal, done.

Unless it's perfectly sealed it will swell in no time.

I would get half a sheet of treated 3/4 plywood, some mortar, grout and cheap tiles. Cost probably less than $75. plus labor.

When its time to move, take the hammer to it.

Would that be OK for handling food?

I wouldn't even mess with the plywood. Spend $10 on a 3x5 sheet of durock. It'll wear better and the tile will stick better.
