PRODUCT APPLICATION
READ ALL INSTRUCTIONS CAREFULLY BEFORE STARTING PROJECT
SURFACE PREPARATION
Proper surface preparation is critical to achieve best results. The surface must be structurally sound and free of dirt, dust and other contaminants. Remove any oil or grease with RockSolid Heavy Duty Cleaner (sold separately). Scrub with a stiff bristle brush or broom. Rinse thoroughly with fresh water. A power washer is preferred. Repeat as necessary to completely clean and rinse. Allow to thoroughly dry.
APPLICATION
Use only with adequate ventilation. RockSolid Concrete Hardener is ready to use. Do not thin. Use only when air (ambient) temperature is between 50-90°F (10-32°C) and the relative humidity is below 85%. Shake the container vigorously for 30-45 seconds. Completely saturate the surface using a low-pressure sprayer or by pouring the product directly on the floor. Spread the material around on the floor with a stiff bristle broom or squeegee to work the product into the floor. Using a hose or sprayer, mist the surface with water to keep the floor wet for 30-45 minutes. After 45 minutes, squeegee or broom the excess moisture from the surface. IMPORTANT: Wait a minimum of 2 hours, then flush the surface with water and squeegee to a surface dry condition. Failure to flush the surface will result in the appearance of efflorescence and will require the use of RockSolid Efflorescence Remover(sold separately).
COVERAGE
On new concrete, each gallon will cover 200 square feet per gallon. On old concrete, each gallon will cover up to 150 square feet per gallon. Areas with crazing (fine cracks on the surface) may take two applications.
DRY TIME
Dry time is based on 70°F and 50% relative humidity. After flushing the surface, the surface will be ready for foot traffic after 2 hours and auto traffic after 12 hours. Wait a full 24 hours before applying a stain, sealer or coating.
CLEAN-UP
Wash tools and equipment with soap and warm water. Clean spills with mineral spirits. Properly dispose of all soiled rags and protect unused product from freezing.
