Limitations Do not dilute or alter after proper mix of concentrate. Application temperature range 35º to 85ºF (2º to 49ºC). Protect from freezing. May damage glass, aluminum, metal, ceramics & glazed tile. Always protect these surfaces. Not recommended for glazed surfaces.

ALWAYS TEST each type of surface to ensure desired results. Let test area dry before inspection.
Over application to dense or dark colored surfaces may produce a white film after drying. This indicates that the product was applied too heavily. Retest using higher coverage rates.

Application Steps:

  • Clean surface to bare concrete using SealGreen Cleaner to remove dirt and oil.
  • Inside applications – Clean by washing, if possible; by sweeping or vacuuming; or lightly mopping the surface. We recommend the use of SealGreen Concrete Cleaner and then rinse thoroughly. Allow to dry.
  • Outside applications – Pre-treat the surface with SealGreen Cleaner and then wash with a pressure washer (2000 to 2750 PSI – no higher – to prevent etching of the concrete surface) with a medium fan tip. Thoroughly rinse and remove all loose material from surface with pressure washer. Allow to dry.
  • Smooth concrete surfaces like garage or basement floors work in four feet by four feet sections. Spray sealer lightly onto the surface to be treated using a low-pressure garden sprayer with a fan tip. Using a string mop spread the sealer evenly until concrete has moist appearance. Repeat this process throughout the entire surface.
  • Repeat step 4 in areas that are drying faster than others. Repeat this process until the sealer beads on the surface when sprayed. Once sealer beads the sealing, process is complete.
  • Do Not Allow over spray onto glass or metal as it will etch those materials. To clean over spray on glass, metal, plastic; use clean water immediately. Use water to clean tools. Wash hands with soap and water and use hand lotion.
  • Remember: If sealer is over-applied, a white powdery residue may appear. Remove excess sealer with mop.
  • General Application Tips
  • White Powdery Residue: Do not attempt to remove the white powdery residue which may result from over-application before a couple of days have passed as it will only make more white powder. After a weeks, you can usually brush or wash the powder away. Any powdery residue will eventually wear off and go away. White powder results from the sealer that cannot be absorbed drying on the surface of the concrete.

New Concrete: Concrete should be fully cured prior to applying SealGreen Concrete Sealer.

Damaged Concrete: Cracks or spalling should be repaired before applying SealGreen Concrete Sealer.

Surface: “The Cleaner – The Better” – Remove all loose material from the surface of the area to be sealed. Surface should be as clean as possible. Heavily soiled areas should be hosed off or power washed. We recommend the use of SealGreen Cleaner to remove oil, dirt, mold, and other contaminants. Do not use any petroleum-based cleaners when cleaning the surface.

Ambient Temperature: Because SealGreen Concrete Sealer is water-based, the temperature should maintain 50 degrees 24 hours prior to and after the application to insure that SealGreen Concrete Sealer will not freeze.


    • Discard container when empty
    • Sealer is – non-toxic – non-hazardous – non-flammable
    • Keep out of reach of children
