01

How Stain Resistance Works

STEP 1 — SURFACE MODIFICATION

Modifies the Cured Film Surface

The SRC additive migrates to the surface of the curing coating, forming a low-energy, non-porous outer layer.

STEP 2 — REDUCED PENETRATION

Limits Contaminant Penetration

Oils, tannins, and common contaminants have a harder time wetting or penetrating the modified surface, staying closer to the top.

STEP 3 — CLEAN RELEASE

Easier Cleaning & Stain Release

Because contaminants remain near the surface rather than soaking in, routine cleaning removes them before they leave a permanent stain.
