Description

A natural finish, solvent-based sealer featuring an oleophobic additive that repels water and fluids, resisting staining, and eases clean up. Ideal for concrete countertops. Surpassing anything else on the market Countertop 880 penetrates concrete substrates providing oleophobic and hydrophobic properties. Food-safe once cured, this sealer protects countertops against water, fluids, staining, UV light exposure and the wear and tear of everyday use.

Applications

Exceptional when used for:
  • Interior Concrete Countertops
  • Exterior Concrete Countertops
  • Honed marble, slate, travertine, natural stone, tile, grout
Not for use on:
  • Ardex/feather finish countertops
  • Concrete tables that have been sealed with a manufacturers wax or sealer

  • Preparation

    1. New “green” concrete must be properly cured. Concrete should obtain 80% of design strength, typically achieved within 14-28 days.
    2. The concrete substrate must be structurally sound and clean of oil, grease, dirt, wax, curing compounds, efflorescence, paints, previous sealers, adhesives and other contaminants that might interfere with the penetration of the sealer. Power wash, acid etch or mechanically scarify as necessary to achieve the desired surface condition. If acid was used to clean the concrete, neutralize the surface and rinse with water prior to application. Allow for proper dry time before application. The surface-zone moisture content of the concrete should not exceed 4% wt. Do not apply if standing water is visible.
    3. Surface and air temperatures must be at least 40°F during application. Surface and air temperatures should not exceed 95°F. Do not apply when temperatures are expected to fall below 32°F within 8 hours or when rain is expected within 12 hours following application. Keep material from freezing. If freezing conditions exist before application, let the substrate thaw before application. Do not apply during inclement weather or when inclement weather is expected within 12 hours.
    4. Crack, patching and expansion joint sealants can be applied before application; always test for compatibility and adhesion.
    5. Protect people, property, vehicles, window glass, roofing materials, plastic products, shrubbery, landscaping and all surfaces not set for treatment from overspray.
  • Application

    1. Always test a small area before application to ensure desired performance, aesthetics, coverage rates and to verify application technique. Let test area dry thoroughly, 5-7 days, before inspection.
    2. Stir material throughly before and during application. Do not dilute or alter material for purposes other than specified.
    3. Apply with a solvent-resistant roller, brush or low-pressure, non- atomizing sprayer. Apply to saturation letting the first coat penetrate for 5-10 minutes. If applying a second coat, reapply in the same saturating manner wet-on-wet (applying the second coat before the first coat dries). Less material will be needed for the second coat. Roll or broom out any puddles until the sealer penetrates the substrate. If it starts to rain, stop treatment and cover the impregnated areas.
  • Notes

    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.

    Dry Time

    Typical drying time is 4-6 hours at 70°F and 50% relative humidity. Cooler temperatures or higher relative humidity can extend the drying time. Treated surfaces will be ready for pedestrian and vehicle traffic within 24 hours.

    Clean Up

    Clean equipment and tools with mineral spirits. Unused or old material may be disposed of in a waste disposal site in accordance with local, state and federal laws.

    Precautions/Safety

    Avoid contact with skin, eyes and clothing, do not take internally. Use appropriate safety equipment during application and handling. Please refer to the safety data sheet (SDS) for additional precautionary instructions before use.

    Best Performance

    • Proper application is the responsibility of the user.
    • Make sure the most current versions of technical data sheets and safety data sheets are being used.
    • Do not use in immersion service or constant chemical exposure areas.

    Coverage

    1 coat: 50 square feet per 16 oz. 2 coats: 25 square feet per 16 oz. Variations in texture and porosity of substrate will affect the coverage and performance of the product.

  • 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.
