- For Best Application Results
Application temperature range is between 41°F and 95°F. Minimum joint depth is 1⁄4”. Joint size should not exceed 1⁄2” deep by 1-3⁄4” wide. If joint depth exceeds 1⁄2”, use foam backer rod. Sealant should be installed when joint is at midrange of its anticipated movement. Allow sealant to fully cure before applying paint, approximately 24 hours depending on temperature, humidity and depth of fill. Priming not required for most construction materials. For cold weather application, condition cartridges at 70°F prior to use. Do not apply over contaminated surfaces. Use with adequate ventilation. Avoid contact with alcohol and other solvent based cleaners until fully cured. Do not cure in the presence of curing silicone sealants. Store below 80°F in dry place for optimal shelf life.
- Surface Preparation
Surface must be clean, dry, structurally sound and free of old caulk, dirt, dust & other foreign material. Priming not required for most materials. Depending on the joint surface, for best results it may require a thorough wire brushing, grinding, sandblasting, solvent washing and/or primer. A roughened surface will also enhance bond. Taping sides of joint is recommended in any size where an extremely accurate match to the edge is desired.
- Product Application
Cut nozzle tip at a 45° angle to desired bead size. Puncture inner foil seal. Load cartridge into caulk gun. Fill gap or crack with sealant. If necessary, tool or smooth the bead of sealant before it skins over. Clean up excess uncured sealant from surface and tools with Pettit 120 Brushing Thinner. Scrape or cut away excess cured sealant. Do not use Pettit 120 Brushing Thinner to clean hands or skin. Wash hands or skin with soap and water. Paintable in 1 hour, depending on temperature and humidity, with water-based and oil-based paints. Reseal cartridge for storage and reuse.
