H&C® Clear Liquid Hardener & Densifier
H&C Clear Liquid Hardener & Densifier is an amorphous colloidal silica solution designed to both harden and densify concrete. This proprietary formulation penetrates and reacts with concrete faster than conventional systems and produces a harder, more uniform surface. H&C Clear Liquid Hardener & Densifier enhances stained or dyed concrete and is ideal for polished concrete applications.
Where to Use
POLISHED CONCRETE APPLICATIONS SUCH AS:
H&C Clear Liquid Hardener & Densifier is water-based and is very easy to apply. It increases the life expectancy of the concrete and resists blushing and yellowing. H&C Clear Liquid Hardener & Densifier is ideal for polished concrete applications and other commercial decorative concrete flooring projects.
- Pump up Sprayer
- HVLP Sprayer
- Push Broom
- Grinding Equipment with Vacuum
- Auto Scrubber
All concrete must be porous, clean, dry and free of grease, oil & any other contaminates. Remove all old coating, paints or sealers prior to application of H&C Clear Liquid Hardener & Densifier. Once the surface is clean and all old coatings, paints or sealers have been removed, grind the concrete to an initial surface profile of 100-200 grit. This will allow for optimum penetration of H&C Clear Liquid Hardener & Densifier.
***Please refer to the Product Data Page for full Product Application information.
FOR PROFESSIONAL USE ONLY. Mix, shake or stir thoroughly before applying. Temperature for application should be between 50°-90°F. Do not apply if rain is expected in 8 hours before or after application.
Depending on size of work area, H&C Clear Liquid Hardener & Densifier can be applied with a pump up sprayer or a high volume, low-pressure sprayer (HVLP). Apply H&C Clear Liquid Hardener & Densifier to the surface evenly at the rate of approximately 400-500 sq. ft. per gallon. Lightly broom out any puddles immediately after the material has been applied. Allow H&C Clear Liquid Hardener & Densifier to remain on the surface for 20-30 minutes. DO NOT LET ANY AREA DRY OUT during this time. Add more H&C Clear Liquid Hardener & Densifier as needed in order to maintain a uniformly wet surface. After material has completely penetrated the surface, continue grinding and polishing to the intended final surface profile and desired finish. For best results, use an auto scrubber and water to remove residual slurry between abrasive disc grits.
