In a well ventilated area, apply to clean, dry, free of frost (cold weather application) surface for proper application, (do not use soap to clean, silicone won’t adhere to soap residue), for porous surfaces, use sandpaper/wire brush to clean surface before applying, allow 24 hours to cure and bond properly, silicone sealants skin over in 5 mins, dry to touch in 1 hour cures/bonds in 24 hours and can take up to 7 full days to reach maximum strength.
60° ideal curing temp – allow 24 hours, RTV product (room temperature vulcanization) meaning cur begins upon exposure to air expect off gas because of this. Remove old silicone beforehand, seal is better on clean surface vs trying to bod new silicone with old silicone, not SDF certified silicone (wick is used for food contact) not paintable, safe on glass (clean beforehand) safe on copper, a more flexible less permanent option compared to furnace cement and fireplace mortar, OK outdoors water resistant once fully cured, red colored silicone due to red oxide in formula, creates the higher temp rating.
