SOLDALIT® is our very best exterior finish for previously painted masonry surfaces and for bare masonry of all types. Soldalit uses a proprietary formula combining silica-sol and potassium silicate binders, inorganic mineral pigments and fillers, and an acrylate copolymer to form both chemical and mechanical bonds, even on the most difficult to paint substrates, without primer coats. This new-generation mineral silicate paint is ideal for finishing ceramic glazed tile and terra cotta, glass, non-ferrous metals, granite, marble, pebble-dash concrete, and previous acrylic or latex-painted surfaces. It is also ideal for all masonry surfaces exposed to severe weather conditions. Tenacious adhesion is enhanced with Soldalit’s nanoparticle technology that allows penetration of even the densest mineral or masonry substrates and provides a mechanical anchor to most existing organic, latex, or acrylic paints in sound condition.
