Silicone caulks and sealants can be used to bond many common materials, including plastic, metal, glass, and ceramic. Probably the most common household use for caulk/sealant adhesives is caulking cracks. Because these products are so simple to use and their consistency is easy to handle, applying silicone sealants to all your gaps, cracks, or breaks is a snap.

Since silicone is waterproof, silicone sealants are well suited for repairs around bathtubs, faucets, toilets, and sinks. The powerful hold created by silicone caulks and sealants also makes them useful for construction jobs, especially outdoors. Silicone sealants are commonly used to seal windows, bathtubs, sinks, tiles, and plumbing fixtures. Because of their durable features, silicone caulks and sealants are often used for automobiles, appliances, and sealing cables and sensors in electronic devices.
