Abstract: A stable caulk or sealant composition containing as principal ingredients styrene-ethylene/butylene-styrene copolymer, heptane solvent, and a resin is disclosed. The composition is generally employed in a canister pressurized with a propellant to expel a stream of water-impervious sealant to fill cracks, crevices and gaps to water damage. When desired, the sealant is removable from the application area, typically by manually pulling (e.g., with one's bare hands). In some embodiments, a propellant is added with the sealant in a container to propel the sealant out of the container when the sealant is applied.
