Westcoat SC-70F Acrylic Lacquer Flat Sealer is a clear, single component, VOC-compliant solvenated lacquer sealer and glaze. It is a very hard acrylic polymer that is UV and stain resistant and is designed to protect and beautify concrete substrates. The solvent base can help the material to penetrate and adhere to concrete. It will darken the substrate and produce a flat or “natural look”.

Clean Up

Uncured material should be removed with an environmentally-safe solvent.; Cured material should be removed mechanically.

Coverage

Will vary depending on the surface.; Up to 400 square feet per gallon on a smooth surface and between 200-300 square feet per gallon on a rough surface.

Dry Time

For best results, allow the product 4-6 hours drying time at 70 degrees before permitting light pedestrian traffic or additional coats are applied.; Allow 24 hours to cure before heavy traffic is permitted.; Allow 48 hours before heavy objects are placed on the surface and allow 72 hours for vehicular traffic.; Allow 5 days prior to any abrasion or chemical exposure.

Moisture

All concrete should be tested for moisture before applying a seamless coating.. If moisture emissions exceed 5 lbs/1000 square feet/24 hours (ASTM F1869) or if the relative humidity (RH) exceeds 75% (ASTM F2170), contact the manufacturer before application.

Thinning

The material may be thinned by adding up to a maximum of one quart of water per gallon, for the first coat.. For best results, it is not recommended to thin the final coat.
