- Application Instructions
For best results, surface and air temperature should be above 50°F and below 90°F. Temperature should not fall below 40°F for 24 hours following application. Do not apply if rain is expected within 12 hours of application. Stir thoroughly before and during application. A minimum of two coats is recommended. DO NOT THIN.
- First Coat: Apply first coat liberally and evenly, working in one direction. DO NOT OVERAPPLY. Remove excess material by back-rolling. Allow to dry at least 4 hours before applying second coat.
- Second Coat: For best coverage, apply second coat perpendicular to the first coat. Two coats are usually sufficient. A third coat may be necessary to ensure uniformity, depending on the porosity of the surface. One coat is usually sufficient when applied over H&C® ColorTop® Solvent-Based Solid Color Concrete Sealer 250.
Slip Resistance
Some surfaces may require a slip/skid-resistant additive for safety. Surfaces may be slippery when wet and proper preventative precautions are recommended. To increase slip/ skid resistance, add H&C® SharkGrip® Slip Resistant Additive to the coating when applying. See product data page for detailed instructions. The addition of anti-slip/skid additives will not eliminate the possibility or risk of slipping/skidding or falling.
Cleanup
Clean tools with xylene following manufacturer’s safety instructions. Use waterless hand cleaner to remove dried material from skin.
Maintenance
Clean light to moderately soiled surfaces with a 50/50 solution of H&C® ConcreteReady® Cleaner Degreaser and water. Use the cleaner at full strength for heavy soiling, such as oil and grease stains.
- Jobsite Test Section
Due to the wide variety of substrates, preparation methods, application methods and environments, it is important to create a test sample.
Limitations
Only use on interior surfaces if the area allows for good ventilation. Strong solvents, such as gasoline or brake fluid, will dull the cured film. Do not use on wood surfaces. Not recommended for immersion (underwater service).
Surface Preparation
- Newly poured concrete must be at least 28 days old. Newly installed pavers should weather a minimum of 60 days; excess joint sand should be swept off the surface prior to sealer application. All concrete must be clean, dry and free of grease, oil, paint, sealers, etc. A high-pressure water wash is recommended. To spot clean, use H&C® ConcreteReady® Cleaner Degreaser, following label instructions. If mold, mildew or fungus are present, kill and remove with a solution of one cup household bleach to one gallon of water. Wear protective eyewear, waterproof gloves and protective clothing. Quickly wash off any of the mixture that comes in contact with your skin. Do not add detergents or ammonia to the bleach/water solution. Surface should have the feel of 120-grit sandpaper at minimum, and readily absorb water. To test absorption, spray various sections of the surface to be sealed with water. If the water does not absorb rapidly, concrete must be etched with H&C® ConcreteReady® Etching Solution, following label directions. If the surface does not feel like 120-grit sandpaper following the first application, a second etching is required. (NOTE: Porous vertical surfaces, such as standard CMU, split-faced block, and exposed aggregate, generally do not require etching.) Prepared concrete must have a pH level between 6 and 10. Allow 24 hours to dry before sealing.
- Previously Painted or Stained Concrete: Make sure all previously painted or stained surfaces are in sound condition. Scrape and sand all loose material prior to the application. To ensure adequate adhesion of the sealer, scuff sand all remaining stain or paint.* Reapplication of the stain or coating may be necessary to create an even, uniform appearance. To remove light soil from the surface, use H&C® ConcreteReady® Etching Solution mixed to a 50/50 ratio with water. To remove heavy oil and grease stains, use the cleaner full strength.
- Repair: Use H&C® ConcreteReady® Quick Patch and Repair, following label directions, to fill low spots and spalled concrete. Note: Patching compounds will generally be visible through clear coatings.
*WARNING: Removal of old paint by sanding, scraping or other means may generate dust or fumes that contain lead. To avoid exposure to lead dust, wear proper protective equipment, such as a properly fitted respirator (NIOSH approved) and follow proper containment and cleanup procedures. For more information, call the National Lead Information Center at 1-800-424-LEAD (in U.S.) or contact your local health authority.
