I’ve got a concrete slab floor which was poured directly onto grade. No moisture barrier (I know, I know..) Is will show signs of moisture if you place plywood or plastic down. In the wet season it shows efflorescence.

I’ve used two part solvent epoxy paints, both smooth and antiskid, but don’t think it will stay.

What can be done to get a uniform color on the slab and seal the surface to allow it to be cleaned easier.

Thanks for your thoughts.
