Why can't you just coat over the old paint?

Because the new coating is only as good as what it bonds to. If the old paint lets go, the new coating goes with it. Prep removes the unknowns.

Will grinding make a mess?

We use HEPA dust extraction on grinders. There's still cleanup involved, but it's controlled.

How long does prep take?

Depends on the slab size, condition, and the system going on top. We'll give you a real timeline after we see the floor.

Prep is the job

Concrete Grinding and Surface Preparation

A coating doesn't bond to dust, laitance, sealers, or paint. It bonds to clean, mechanically profiled concrete. Everything we install starts here, including our garage floor coating systems.

Diamond grinding

We use planetary grinders with diamond tooling to remove old coatings, glues, sealers, and the top layer of weak concrete. The goal is a uniform, profiled surface that the coating system can mechanically lock into.

Shot blasting

For larger commercial slabs or aggressive profiles, shot blasting throws steel media at the floor and recovers it in the same pass. The result is a deeper, more aggressive profile suited to heavy-build systems.

Crack and joint repair

Cracks get chased out, cleaned, and filled. Control joints get treated based on the system spec and how you want the finish to read. None of this happens after the coating goes down, it happens before.

Moisture and contamination

We assess slab moisture and surface contamination before quoting. If the slab needs a moisture mitigation primer or extra remediation, we tell you up front, not after the floor is already failing.
