  • Preparation

    Avoid contact with skin, eyes and clothing. Wash hands after use and do not take internally. Please refer to the product Safety Data Sheet (SDS) before using. The preparation process should be followed to ensure adequate penetration and optimum performance:

    Step 1: The concrete substrate must be structurally sound, thoroughly dry and clean. Wait at least 24-48 hours after rain and/or pressure washing before sealing; concrete should be visibly dry.

    Step 2: Remove all paints, previous sealers and/or adhesives before application.

    Step 3: The substrate must be clean of oil, grease, dirt, wax, curing compounds, efflorescence and other contaminants that might interfere with the penetration of the sealer.

    Step 4: If acid is used to clean the concrete, neutralize the surface completely and rinse it with water prior to application. Then wait for the concrete to dry out for at least 24-48 hours.

    Step 5: The surface-zone moisture content of the concrete should not exceed 4%wt.

    Step 6: Cover all surrounding areas not intended to be coated.

    Step 7: New concrete must be cured for at least 28 days before sealing.

  • Application

    Step 1: Countertop Sealer 880 is ready to use right out of the container. Stir extremely well before use.

    Step 2: Pour the Countertop Sealer 880 into a paint tray or bucket and drip a small roller or paint brush into the bucket.

    Step 3: Roll or brush one coat of the Countertop Sealer 880 on to the concrete countertop.

    Step 4: Immediately apply a second coat while the first coat is still wet. Apply until the surface is saturated but not to the point of puddling. (Since the Countertop Sealer 880 is a hydrophobic product if you try to apply a second coat after the first coat has dried, the first coat may try to repel the second coat.)

    Step 5: Roll or brush out any puddles until the sealer penetrates the substrate.

    Step 6: When the entire application has been treated with two (2) coats, let the concrete dry for at least six (6) hours before light use and at least 24 hours before placing objects back on the countertop for normal everyday use.

    Step 7: Clean up: Application tools can be cleaned using xylene.

    Step 8: Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

    Application Notes

    • Before application test the sealer by applying in an inconspicuous area to ensure the desired coverage and appearance is achieved.
    • Do not over apply.
    • Prevent from getting on glazed and finished surfaces such as glass, aluminum etc. In case of contact flush immediately with water.
    • Do not use on concrete that has been previously sealed without chemically etching or mechanically scarifying.
    • Water repellency may take up to seven (7) days to develop.
    • Maintenance: The concrete surface can be cleaned with mild soap and water. No citrus or vinegar-based products should be used. Organic does not always mean “mild” and can include citrus ingredients that you’ll want to avoid.
  • FAQ

    What does wet-on-wet mean? Wet-on-wet means that the second coat is applied while the first coat is still wet. Two coats of the Countertop 880 are required wet-on-wet. The second coat is applied immediately after the first coat while the first coat is still wet, since the Countertop 880 is a hydrophobic product it will try to repel the second coat if the second coat is applied after the first coat has dried.

    Does the concrete need to be dry before sealing? Yes, the concrete needs to be as dry as possible before sealing. We recommend the moisture content of the concrete be less than 4% wt. It is recommended to wait at least 24-48 hours after rain and pressure washing before sealing.

    What is the difference between the Countertop 880 and the Countertop 770? The Countertop 880 is a solvent based product and the Countertop 770 is a water based product. The solvent based Couuntertop 880 features increased performance, stain resistance and longevity.

    Where can I buy this product? The Countertop 880 is available through a number of distributors found on our distributor page.
