DAP 100% Silicone All Purpose Sealant

DAP 100% Silicone All Purpose Sealant is a durable, 100% waterproof and weatherproof sealant built for sealing out drafts, water and moisture around windows, doors, siding, gutters, flashing, pipes, vents and more. This all-purpose sealant family is available in 4 colors — Almond, Black, Clear and White — and in 2 cartridge sizes, 2.8 oz and 9.8 oz, so you can match the seal to the surface and pick the cartridge size that fits the job. Every option delivers the same flexible silicone rubber bond that stays pliable through expansion and contraction without cracking or losing adhesion, so seams stay sealed through seasonal temperature swings.
