Kelmore’s PrimeMore CS is a ready to use, one coat primer specifically designed for use on calcium sulphate/anhydrite screeds. PrimeMore CS penetrates and seals the screed’s surface creating a barrier, eliminating any adverse reaction with cementitious adhesives and flooring compounds. PrimeMore CS also improves the workability, adhesion, and strength of subsequently applied products. To help achieve total and uniform coverage, PrimeMore CS is pigmented red for enhanced visibility during application.
