The 40+ standard stain colors shown are representative & approximate, as closely as possible, concrete with a flat troweled finish, sealed with BRICKFORM, solvent-based, Gem-Steal. Standard vs Acid Based Stains: Standard stains fill the pores of the concrete surface to produce a consistent color. Acid-based stains penetrate & chemically react with the concrete to form a translucent color with rich tones and attractive marbling effects.
Perma-Cast Sierra Stain is a penetrating reactive stain that chemically combines with cured concrete to produce a permanent variegated coloring effects. Perma-Cast Sierra Stain is perfect for exterior hardscape, artificial rock formations, interior floors, walls, statuary and countertops. Because there are so many variables involved in the chemical reaction process there will be wide color variations, mottling, and unevenness. This is normal and usually desired.
