LITHOCHROME® Colorwax™ Concrete Curing Compound
A colored concrete curing compound that reduces moisture loss and improves visual uniformity of freshly placed colored concrete
LITHOCHROME® Colorwax™ Concrete Curing Compound is a colored concrete curing compound that reduces moisture loss from freshly placed concrete. Use during concrete placement, to reduce surface cracks and color variations caused by uneven drying and efflorescence that commonly occurs in warm, windy, or dry environments. It is not a paint or concrete sealer, and will gracefully wear, weather, and dissipate over several months without the appearance of peeling or chipped paint. As freshly placed concrete cures, its color will vary with differences in surface moisture. Concrete in shaded areas or in the center of large slabs will surface dry slower than those exposed to sunlight or closer to form edges. If salt content of aggregates are high, efflorescence can bloom to the surface and lighten colors. These visual differences can be long lasting, and raise questions about the quality of the concrete placement. LITHOCHROME® Colorwax™ Concrete Curing Compound enables contractors to immediately deliver jobs that are uniform in color and appearance.

Store at 40°F to 120°F (4°C - 49°C). DO NOT FREEZE!
Application
APPLICATION INSTRUCTIONS
If using spray equipment, always wear protective respirator, and mask adjacent areas to protect property from overspray. Remove overspray immediately with soap and water.
Coverage Rates
Coverage will vary depending on the porosity and texture of the surface, and application technique. Typical coverage rate is 100–400 ft2 per gallon (2.25–10 m2/L). Porous, broom or textured finishes will require more product. DO NOT THIN OR REDUCE!
Equipment
Apply LITHOCHROME® Colorwax™ Concrete Curing Compound by brush, roller, HVLP, airless, or pump-spray application. Always wear protective clothing and equipment proper for the method of application. If using a roller, use a quality 3/8" knap with tapered edges.
Spray applicator Guidelines:
Pump Garden Sprayer: Use conical tip.
Airless spray: 1500–2500 psi (10–17 MPa) fitted with a fan tip of 0.013–0.018 inches (0.33–0.46 mm).
HVLP spray: 5–40 psi (35–275 kPa)
When to apply a Colored Concrete Curing Compound
Apply LITHOCHROME® Colorwax™ Concrete Curing Compound when concrete is walkable and all bleed water has either reabsorbed into the concrete or evaporated.
Mixing
Prior to combining Part A with Part B, mix each separately until it is uniform. LITHOCHROME® Colorwax™ Concrete Curing Compound Part B is milk white and will look like a heavy cream prior to tinting. Combine Part A and Part B and mix until it is again uniform consistency and appearance. The material is now ready for use. Some heavier tints will produce more material than the gallon container of Part B will hold. In these cases, mix products together in a clean plastic pail.
APPLICATION
Jobsite Test Sections
Verify and approve suitability and appearance by making jobsite test sections prior to general application. Each individual concrete color, finishing technique, and sealer combination should be verified. Test sections must be of adequate size to be representative and be produced by the same workers who will apply product to the larger job. Test completed systems for wet and dry slip resistance to ensure they are safe. Do not proceed with products, techniques, or finishing systems that do not meet required safety specifications or site owner approval.
Application
Distribute product with a pump garden sprayer fitted with a conical tip, followed by back rolling with a quality 3/8" knap roller. Roll in multiple directions to ensure product penetrates into concrete cracks, joints, and pores. Take care not to create lap marks as they cannot be removed once the product has dried. LITHOCHROME® Colorwax™ Concrete Curing Compound is designed to match the final concrete color, it may first appear lighter than the freshly placed wet concrete.
Dry times will depend upon the selected coverage rate, penetration into the substrate, and weather conditions. At 70 °F and 50 % relative humidity with an application rate of 400 sq. ft. per gallon (10 m2/L), dry to touch and recoat times of 1–2 hours are expected. Avoid foot-traffic for a minimum of 12 hours after final application.
Cleaning of Equipment
Clean equipment with warm water and detergent immediately after application.
