About Expansive Triangle Epoxy Flooring

Most of what makes an epoxy floor last, or fail, happens before any color ever goes down. A lot of contractors use acid etching to prep concrete because it's quick and cheap. The problem is that acid etching only lightly roughens the surface, and it can leave a residue that actually weakens the bond. That's a big part of why some epoxy floors start peeling or bubbling within a year or two.

We diamond-grind every floor instead, mechanically grinding the concrete down to a clean, exposed surface using diamond-segmented tooling. It takes more time and better equipment, but it means the epoxy bonds directly into the concrete rather than sitting on a lightly-scuffed surface. If you've had a bad experience with a peeling garage floor before, this is almost always why, and it's the first thing we'd do differently.
