• NOT recommended for mirrors, sensitive metals (copper, brass, lead), Teflon, polyethylene, polypropylene plastics, and porous surfaces such as stone, concrete, marble, and granite
• Ideal application temperature range: +40°F to +90°F for optimal performance. Temperature resistance range: -40°F to +302°F
• How to use: 1) Ensure the application surfaces are clean and dry. If needed, apply masking tape to protect adjacent areas. 2) Cut off the end of the tube to open it. 3) Trim the nozzle tip to the desired size and attach it to the tube. 4) Insert the tube into a caulking gun. 5) Apply the sealant evenly to the surface. Smooth it with a tool or a gloved finger to fill the application area. 6) After use, reattach the cap on the nozzle to prevent curing. 7) Remove the masking tape. If needed, use clamps to hold surfaces together until the sealant cures. 8) Wipe away any excess sealant with a cloth dampened with solvent before it cures. Once cured, the sealant can only be removed mechanically.
• Full curing takes 24 hours; avoid direct water exposure before the sealant is fully cured
• Non-paintable, ideal for applications where permanent transparency is preferred
• Store in a cool and dry place between 40°F to 75°F, away from direct sunlight and heat sources. Properly seal the container to prevent moisture infiltration. Keep upright to avoid leakage and store in a secure location out of reach of children.
