Application temperature: Above 10°F
Service temperatures: -75°F to 250°F
Methods of application: Cartridge/caulking gun
Working time: Approx. 10-15 minutes for a 1/4” bead
Working surfaces: For best results, surfaces should be clean, dry and free from any material that may deter adhesion.
Cleanup: Clean tools and excess material with minneral spirits before it dries. Scrape dried excess.
Extrudes slightly yellow and dries crystal clear. Air, caulk and surface temperature should be above 10°F. If desired, it may be painted with water-based paint immediately (wet-on-wet). For other types of paints, we recommend a compatibility test. If joint depth exceeds 1/4”, use backing material. Not designed for continuous submersion or use below the waterline. Do not use for aquariums.
