The original commercial acid stain, colorful LITHOCHROME Chemstain Classic adds beautiful translucent special effects to concrete. The reactive, penetrating concrete stain produces unique, permanent concrete color effects. Chemstain is ideal for creating an antique, mottled, variegated patina for exterior hardscapes, interior floors, or artificial rock and water features.
LITHOCHROME Chemstain Classic penetrates and permanently stains new or existing concrete and cementitious toppings and wears only as the concrete wears. Use this time-tested reactive concrete stain for
* Popular, creative, faux finish effects
* Permanent, variegated colors
* No chipping and no peeling
* Distinctive, lasting results
Multiple applications of concrete stain can intensify colors. Infinite effects can be achieved by either layering the stain colors or applying the stains over other Scofield coloring systems or colored cementitious toppings.
For best results in large areas, professional quality, acid-resistant hand-pump sprayers are recommended. Compatible Scofield concrete sealers should be used to protect the finished surface.

Applicable Standards for LITHOCHROME® Chemstain® Classic
Newly placed concrete should be sufficiently cured, a minimum of 14 days. However, on interior applications of the Chemstain colors Copper Patina, Fern Green, and Weathered Bronze, the concrete must be sufficiently dry (typically 1428 days) so that the Moisture Vapor Emission Rate (MVER) is less than 5 pounds per 1000 square feet per 24 hours (2.5 kilograms per 100 square meters per 24 hours) based on a 72 hour test period per ASTM F1869. The Warning Section on page 1 should be read.
Liquid curing materials must not be used. Concrete flatwork should be cured with new and unwrinkled, nonstaining, high-quality curing paper conforming to ASTM C 171 Sheet Materials for Curing Concrete.
Exterior flatwork or interior floors topped with SCOFIELD Texturetop must be sufficiently cured to walk on without damage prior to staining, at least 48 hours after installation at 70° F (21° C). SCOFIELD Texturetop cures at a rate similar to concrete and retains moisture which, when using the LITHOCHROME Chemstain Classic colors Copper Patina, Fern Green, or Weathered Bronze, can in some instances cause darkening if the Chemstain solution is applied too early. Prior to using these colors, the Texturetop topping must be sufficiently cured, normally 1428 days, and the Moisture Vapor Emission Rate (MVER) of the topping should be less than 5 pounds per 1000 square feet per 24 hours (2.5 kilograms per 100 square meters per 24 hours) based on a 72 hour test period per ASTM F1869.
Coverage Rate for LITHOCHROME® Chemstain® Classic
Approximate Coverage: 200-300 ft2/gal per coat. Do not dilute.
(Or 4.9-7.4 square meters per liter per application.)
LITHOCHROME Chemstain Classic is available in 1-Gallon and 5-Gallon Pails.
Coverage will vary depending on the porosity and texture of the surface, composition and age of the concrete, preparation and application techniques, number of applications, and other factors.
