Existing Coating Removal

KD Epoxy Floor removes existing floor coatings across South Florida when old, peeling, or incompatible product has to come off before a new system can bond. We mechanically strip the surface without damaging the slab underneath, then profile it for the new coating.

A new coating is only as good as the substrate it bonds to. Coating over a failing layer means the new coating fails with it, so removal is often the first step of a lasting floor. We come to your property to assess the existing coating and send a custom estimate — share your city or ZIP and we'll confirm availability.

Removal is the mechanical stripping of an old coating to reveal the slab underneath. We identify the coating type, choose the removal method that protects the slab, strip the surface, and profile it for the new system. The goal is a clean substrate, not a gouged slab.

Methods range from mechanical grinding and scraping to chemical strippers where appropriate. We default to mechanical removal because it protects the slab, and we use chemical methods only where mechanical removal would damage the surface or where the coating requires it.

Garages, commercial floors, driveways, and patios — any slab with an old coating that has to come off before a new system goes down. If the existing coating is peeling, soft, or incompatible with the new product, it has to be removed.

We also remove coatings to inspect the slab condition underneath, because a failing coating can hide slab damage that needs repair before the new floor. What the old coating was hiding often determines what the new floor needs.

Mechanical grinding is the default — it strips the coating and profiles the slab in one step. Scraping handles softer coatings. Chemical strippers are used where mechanical removal would damage the surface or where the coating requires it.

We test the coating type and adhesion before choosing, because the wrong method damages the slab or leaves residue that compromises the new coating. A coating that is peeling comes off differently than one that is well-bonded, and we adjust the method to match.

We identify the existing coating, select the removal method, mechanically strip the surface, and profile for the new system. The process is dusty and loud, and the space needs to be cleared and ventilated.

After removal, we assess the slab condition underneath — cracks, spalls, and moisture — before the new coating follows. Removal often reveals work that needs to be done before coating, which is why we treat it as the first step of the new floor, not a separate cleanup.

A new coating bonds to the surface under it. If that surface is a failing coating, the new one fails with it — the bond is only as strong as what it is bonded to. Removal gives the new system a clean substrate, which is why it is often the first step of a lasting floor. See our diamond preparation and polishing for the profiling step that follows removal.

An old coating can hide a lot — cracks that have spread, spalls that have grown, moisture damage, or previous patch jobs that are failing. Removal is how we find out what the slab actually needs before the new floor goes down. That is why we treat removal as an assessment step, not just a cleanup.

For South Florida slabs, that matters. Humidity and seasonal movement take a toll under a coating that is hiding the damage, and removal is how we catch it before the new floor covers it up again.

Not every removal is a precursor to a new coating. We also remove coatings for slabs that will stay bare — a driveway where the old sealer is failing, a patio where the coating is peeling, a garage where the owner wants polished concrete instead. The removal method is the same; what follows is what differs.

We profile the slab for whatever comes next, whether that is a new coating, a polish, or a bare concrete surface. See our coated floor renovation and maintenance for when an existing floor can be saved instead of removed.
