What Is Elastomeric Sealant?
Elastomeric sealant is a building material used to fill and seal up spaces. With a rubbery liquid texture that dries hard but retains flexibility, it can be easy to work with and is typically long lasting. When applied or inserted into a crack or space, elastomeric sealant expands and seals to the surface, creating a waterproof barrier. It is barely visible or invisible on most materials, and may be used indoors or out. A chemical compound, or polymer, called elastomer makes up elastomeric sealant. It is strong and spongy-hard and rubbery, making it an elastic polymer. Typically it comes in a tube, tub or can and is semi-liquid and creamy, which makes it very malleable for application by hand or with a caulking gun. Hardware and specialty stores that carry building materials usually stock sealants.
