The single biggest reason garage floor coatings fail is inadequate surface preparation. Concrete is naturally smooth, dense, and frequently contaminated with oils and curing compounds.
The Problem With Acid Etching
Cheap DIY kits suggest washing concrete with muriatic acid. However, acid etching fails to open hard troweled concrete, leaves trapped moisture and corrosive salts in the slab, and does not level high spots or remove tire sealants.
The Superiority of Diamond Grinding
At Soares Epoxy, we use 600-pound industrial planetary diamond grinders equipped with HEPA dust containment. The diamond segments abrade the surface to a textured Concrete Surface Profile (CSP) 2, creating millions of microscopic anchor points that allow the primer to penetrate deeply and fuse permanently into the slab.
