Our hero service — Epoxy Flooring
The Master Seal
epoxy system.
A floor is only as good as what sits underneath it. We diamond grind the slab, repair what needs repairing, prime, apply your colour base and decorative flakes, then finish with two protective clear coats — not one.
Diamond Grinding & Slab Preparation
We mechanically prepare the existing slab with professional diamond grinding equipment. Correct preparation is fundamental to adhesion and long-term performance.
Patching & Surface Repairs
We inspect the slab and repair appropriate cracks, holes, surface imperfections and damaged sections to create the best possible foundation. Structural issues are assessed separately and are not resolved by a coating.
Primer
A professional primer system is applied to the prepared substrate, creating the foundation between the slab and the epoxy layers above it.
Epoxy Base Coat
Your selected AS2700 epoxy base colour is applied across the prepared floor.
Decorative Flakes
Your selected decorative flake blend is broadcast across the epoxy base. Prefer a clean, uniform look? A solid-colour system is available instead.
First Clear Coat
The first protective clear coat is applied over the cured base and flake layer.
Final Clear Coat
A second clear protective coat completes the Master Seal epoxy flooring system. Two clear coats — not one.
