Kelmore’s PrimeMore Universal is a primer designed for use on porous/absorbent wall and floor backgrounds prior to applying tile adhesives or levelling and smoothing compounds. PrimeMore Universal regulates the porosity of the background, enhancing the workability, adhesion and strength of subsequently applied Kelmore products. When backgrounds are sufficiently primed using PrimeMore Universal, the surface finish of levelling and smoothing compounds will also be significantly improved. To help achieve total and uniform coverage, PrimeMore Universal is pigmented blue for enhanced visibility during application, and is suitable for interior and exterior use.
