SikaColor - 420 Chemstain (1Gal Unit)

SikaColor®-420 Chemstain® is a penetrating reactive stain that chemically combines with cured concrete to produce permanent, variegated coloring effects. When applied to concrete or some other cementitious materials such as overlays, the stain reacts with the free lime to create colored mineral deposits in the pores of the surface. Because there are so many variables involved in the chemical reaction process (i.e., mix design, age, porosity, texture and color of the concrete substrate), each application of SikaColor®-420 Chemstain® produces unique results. Expect wide color variations, mottling and unevenness of the color, within the confines of the concrete slab and from slab to slab.

(Previously named Sierra Stain® Reactive Acid Stain and LITHOCHROME® Chemstain® Classic.)
