Cove Waterproof Silicone Sealant

Joints and gaps move — with temperature, with vibration, with time. Cove is a silicone sealant that cures into a waterproof seal and stays flexible afterwards, so the joint doesn't crack the first time things shift.

Why you'll love it

• Strong adhesion: bonds reliably to many materials — glass, concrete, metal, brick, tile, and more — and stays stable even under stress.
• Permanently flexible: adapts to expansion, movement, and vibration after curing, reducing the risk of cracks in the seal.
• Weatherproof: protects joints and transitions against moisture and weather in typical outdoor applications.
• Quick, clean work: cures rapidly and finishes cleanly, and the neutral-curing formula keeps odor low while you work.
