Rapid Set


High-Adhesion Acrylic Primer

DESCRIPTION: Rapid Set® CONCRETE LEVELER™ PRIMER (CLP) is a ready-to-use acrylic primer that improves the adhesion of Rapid Set® Concrete Leveler® to prepared concrete. CLP acts to prevent pinholes and bubbles from forming in the finished surface.

SURFACE PREPARATION: CLP is intended for use on prepared concrete. Surface must be dry, porous, clean, sound, and free of oil, curing compounds, dust, mastic and other bond breakers. Mechanically profile the surface by shot blasting or grinding. Acid etching the concrete surface is not recommended.

MIXING & APPLICATION: Shake well to ensure primer is thoroughly mixed and there is no sediment in the container bottom. Mix at low speed with a drill and paint mixer. Apply primer to substrate and work into the concrete surface with a soft-bristle push broom. Paint roller or spray application will not achieve sufficient coverage. Spread evenly to avoid puddles and to thoroughly coat the surface. Maintain material, surface and ambient temperatures above 50°F (10°C).

For excessively porous or absorbent concrete surfaces, multiple coats may be necessary. Prime the surface with an initial application of diluted primer at a ratio of 1 part water to 1 part primer. Allow to dry and become tack free. Then, apply a second coat of undiluted primer. Repeat as necessary until the final coat of primer stays wet for at least 20 minutes. Lower temperatures and/or higher humidity will extend drying time.

Apply Concrete Leveler after the primer is dry (usually 30 minutes to 3 hours) and within 24 hours of the final primer coat. If more than 24 hours have elapsed, reapply primer.

COVERAGE & PACKAGING: CLP is available in 1 quart and 1 gallon bottles. Coverage is about 50 ft2 to 100 ft2 (4.6 m2 to 9.3 m2) per quart or 200 ft2 to 400 ft2 (18.6 m2 to 37.2 m2) per gallon.

SHELF LIFE: CLP has a shelf life of 2 years from date of manufacture if kept in a cool environment, out of direct sunlight. Do not allow material to freeze.
