Can you epoxy over tile, paint or an old coating?
We get this call weekly: can you go right over what's there? The honest answer depends on what's under the new floor — because a coating is only as strong as what it's bonded to.
Over old epoxy or paint
Almost never directly. Old coatings have unknown adhesion — if they let go, your new floor goes with them. We diamond-grind them off to bare concrete, which also gives the new system the mechanical profile it needs. It's more work; it's also why ours lasts.
Over tile
Possible in some commercial situations with heavy preparation (grinding the glaze, filling grout lines with build coats), but on most residential jobs, removing tile and coating the slab beneath gives a flatter, more durable, better-looking result — often at similar cost once tile prep is priced honestly.
Over cracked or damaged concrete
Yes — after repair. Cracks are routed and filled, spalls patched with structural mortar, and moisture is tested. A coating bridges hairline imperfections beautifully; it doesn't fix structural movement, so we address causes first.
