Safety Data Sheet
Installation Instructions

APPLYING CS-1500

CS-1500 may be factory or field applied to seal various construction components. No primer is required except on masonry subjected to continuous immersion. Some substrate surfaces may require special cleaning or treatment for optimum performance. Tooling techniques using solvents or soapy solutions are not recommended.

INSTALLATION

Concrete and masonry surfaces must be free of foreign matter and contaminants. Clean dust and loose particles out of joints. A clean, dry, sound and uncontaminated surface is mandatory. Stone surfaces must be cohesively sound, dry and free of contaminants. Granite, limestone, marble and sandstone must be pre-tested for adhesion prior to sealant installation. Mill finish aluminum may contain an invisible oil film or oxide. Clean working surface with alcohol. Many high-performance coatings or unusual surface treatments may require abrasion of the surface with steel wool or fine emery paper during preparation. In cases where doubt exists, consult Concrete Sealants for recommendations.

Joint design

Recommended maximum joint width should not exceed 1 1/4” (1.250) (3.175 cm) and the maximum joint depth should not exceed 1/2” (0.500) (12.69 mm). Minimum joint width should not be less than 1/4” (0.250) (6.34 mm). The sealant depth should be 1/4” (6.34 mm) for joints 1/4” in width. For joints over 1/4” in width, sealant depth should be 1/2 of the joint width but should not exceed 1/2” (0.500) (12.69 mm) in depth. In order to obtain the recommended sealant mass the joint should be filled with Caulk Backer Rod first, leaving a depth to be filled with sealant. CS-1500 will accommodate up to 50% total joint movement. Desirable backer-rod materials are polyethylene or polyurethane non-gassing foamed rod. Do not puncture the closed cell structure of closed cell polyethylene rod as bubbles could form and migrate to the surface of the curing sealant. The use of open cell backer rod material minimizes this condition.
