Concrete must be at least 7 days, and preferably 28 days old. Surfaces must be dry and clean of all prior sealers, curing compounds, oils, or other foreign materials that might prevent penetration. If used as a first stage densifier or dye-lock for concrete polish work, grind to the desired aggregate exposure ending with 80 to 200 grit tools. Use brooms or vacuums to remove all grinding dusts, loose concrete laitance, and powders, or the densifier may permanently adhere them to the surface.
Mixing: If diluted, mix until uniform.
Jobsite Test Sections
Verify and approve suitability and appearance by making jobsite test sections prior to general application. Each individual concrete color, finishing technique, densifier, 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
Mask all areas not to be coated to safeguard against splashes, overspray, and runoff from application. Wear all required safety equipment. Take care not to allow tape adhesive to interfere with surfaces to be treated. Surface wet with material will be slippery until dry.
Distribute product with a pump garden sprayer to fully saturate the surface. Surfaces should remain wet 5 to 10 minutes. Work material into the surface with a broom, mop, or sponge to ensure product penetrates into substrate pores and microcracks. Take care not to create lap marks as they cannot be removed once the product has dried. If too much material has been applied, and it is puddled after 30 minutes, dilution and removal with a wet vacuum is recommended.
When the first application is dry to touch, a second coat can be applied to maximize densification properties. If used as a polishing aid, wet polishing can begin when dry to touch.
Dry times will depend upon the selected coverage rate, penetration into the substrate, and weather conditions. At 70°F (21°C) and 50 % relative humidity with an application rate of 400 sq. ft. per gallon (9.8 m2/L), surfaces should be dry and walkable and ready for the next stage of polishing in 1 hour.
If surfaces will not be polished further, or they will be sealed with a coating, wash surfaces at this stage with fresh water to remove excess densifier. When completely dry, surfaces can be returned to service. If sealing, wait 24 hours to allow the densifier to cure.
Cleaning of Equipment
Clean equipment with warm water and detergent immediately after application.
