Originally used to seal food cans and envelops, sealant and caulking have evolved from their initial applications into more useful ones. When installing windows, doors, molding or siding making sure to have a good sealant will keep it looking good, while helping to extend the life of your project. Caulking and sealant may have differences but share the same purpose – to fill gaps between building surfaces keeping water and air out. To some, these products may not seem necessary, but exposure to weather, and other elements, can cause your materials to lose strength and shorten their service life. Caulking compounds provide a long lasting thermal and moisture protective seal between most building materials including wood, stone and tile, brick, drywall, metal, concrete, glass and vinyl. With great resistance to water, weathering and moisture vapor, caulking is the best solution for keeping your next job strong and durable for time to come.
