Epoxy primer designed as a moisture barrier for concrete floors and screeds.
Moisture Vapor Barrier
CHEMPROOF™ SC is a two-component, 100% solids, VOC-free epoxy primer with a 2:1 mixing ratio, formulated with phenalkamine chemistry. It is specifically designed as a moisture barrier for concrete floors with very high residual moisture before the installation of floor coverings, topcoats, or parquet (up to 0.15 bar/cm²).
CHEMPROOF™ SC is also suitable for calcium sulfate-based screeds with slightly higher residual moisture. It can be used as a primer on absorbent, non-absorbent, and smooth surfaces, both indoors and outdoors.
