100% Epoxy. 100% Better.

Floors built to handle real life.

We don't cut corners — ever. Our 100% solids epoxy systems are thicker, stronger, and longer-lasting than water-based products or DIY kits. Every project starts with proper concrete prep and a moisture test, because shortcuts always show up later.
