DIRECTIONS: Use rubbing alcohol to remove dust, dirt, frost and other contamination from Kleer cellular PVC trim products. Do not clean with petroleum solvents such as mineral spirits. It is recommended that a quality caulking gun be used to ensure ease of application. Cut tip at a 45-degree angle to approximately the size of the joint opening and puncture the foil inner seal. Gun a continuous bead into the seam or expansion gap, or completely fill nail holes. Finish promptly with a damp metal tool. Kleer Cellular PVC Structural Sealant skins over in 30 minutes, but may remain tacky for several days. 100% acrylic paint may be applied in 1-2 hours, even if the sealant is still tacky. Apply above 30° F. Clean tools and hands with rubbing alcohol.
