Silicone caulk offers more moisture resistance, flexibility, and durability than standard caulk. Acrylic caulks with silicone are ideal for indoor projects requiring only moderate water resistance, while silicone sealants are waterproof with excellent weatherability and can withstand a wide temperature range. A huge range of high-quality products are available for bonding materials such as PVC, concrete, glass, painted surfaces, wood, plywood, brick, stone, masonry, and more. To best fit the repair job at hand, a variety of colors are offered. Select products will qualify for a bulk discount.
