Repair sealants are watertight adhesives used to fix cracks in exterior surfaces. They come in various types, including marine, driveway, vinyl, and food grade silicone. Each has specific application instructions and drying times. Marine sealant is used to keep boats watertight, driveway sealant improves the appearance and functionality of paved surfaces, vinyl sealant is commonly used for above ground pool repairs, and food grade silicone sealant is used in equipment repairs involving edible products.

A repair sealant is a watertight adhesive used to repair cracks in exterior surfaces. Repair sealants are often made from quick-drying plastic compounds designed to be strong and durable. A wide variety of project specific repair sealant options are available to repair damage to items that come in direct contact with moisture such as boats, driveways, and swimming pools. Some repair sealants are available in kits that include a piece of patching material and application tools. Application instructions and drying times are different for each repair sealant product.

Marine repair sealant is commonly used all over the structure of boats to repair cracks and keep them watertight. Small cracks on a boat can turn into major damage when exposed to the pressure of being tossed by crashing waves. Clear silicone rubber is often used to make marine sealant strong enough to withstand water pressure without causing a leak. Most manufacturers suggest using a hull cleaner to remove any residue from the boat before applying the repair sealant. Silicone repair sealants labeled for marine use are often used as general waterproof repair agents to seal and protect the home.

Driveway Repair Sealant is specifically designed to adhere to rock surface and improve the appearance and functionality of a paved surface. Temperature fluctuation and earth settling can often cause what was once a solid, even driveway to crack and crack. Repair sealant made for use on driveways is usually tinted black and often comes in caulking tubes. Sealant is commonly injected directly into cracks in asphalt driveways to prevent water damage and discourage its spread.

Vinyl repair sealant is one of the most commonly used types. Above ground pool repair sealants can often be applied to small underwater cracks in the vinyl without draining the pool. Larger cracks in the pool material may require the use of a vinyl patch along with the sealant. Within minutes, most vinyl sealants fully cure and form a waterproof seal. Many pool repair sealants are repair sealants designed to remain permanently flexible to prevent future cracking.

Food grade silicone repair sealants are used in equipment repairs involving edible products. Some sealants emit toxic fumes that would contaminate consumer items. Repair sealants specifically labeled as food safe are designed to fully cure without leaching chemicals into the food they come into contact with.
