Why roll-on epoxy flooring peels off a smooth slab
Concrete is closed on the surface. A coating laid onto it without opening that surface has nothing to key into, which is why big-box kits lift in sheets after one or two Toronto winters. We grind the slab with diamond tooling under HEPA extraction until the profile is open, fill and repair the cracks, prime, then build the coating in layers. It is the slow part of the job and the only part that decides whether the floor is still there in five years.
