• Prevents moisture-related problems with floor coverings over concrete floors.
• Serves as an excellent primer for SpecChem Underlayments/Overlayments.

Concrete Surface Preparation:

• New concrete must be at least 5 days old with all curing compounds and sealers removed, and possess a minimum tensile strength of 150 psi.
• Existing concrete must be clean, dry, and sound. Remove all contaminants such as oil, dirt, and unsound concrete.
• Concrete surfaces must be mechanically prepared to a minimum ICRI CSP of 3. Acid etching is not acceptable.

Mixing:

• Condition all materials to a temperature range of 65°F to 85°F.
• Mix Parts A and B separately for one minute using a drill and mixing prop, then combine and mix for an additional 3 minutes to ensure proper chemical reaction.

Placement:

• Spread with a squeegee or notched squeegee and back-roll with a roller to improve bond and reduce surface imperfections.
• While still fresh, broadcast clean/dry sand over the application to create an ideal bonding surface for underlayment or overlayment systems.

Available in 3-gallon units (two 1-gallon Part A resin and one 1-gallon Part B hardener) and 15-gallon units.

Two years from the date of manufacture when stored properly in original, unopened containers in a cool, dry area away from direct sunlight.

Coverage rate is approximately 75-125 sq-ft per gallon, depending on the texture of the concrete surface.
