Why Sealtite is better than caulk?

All gunnable sealants and caulks depend on three material properties to work: adhesion, cohesion, and impermeability to water. Sealtite is designed to address the failure of caulked joints. Sealtite acts under compression at all times, thereby eliminating all factors associated with tensile stresses. Sealtite has no adhesive “glue line”. Instead, it seals the joint wall interface with a high density foam acting under constant pressure and a waterproof, hydrophobic acrylic polymer. This composition provides for long life and resiliency allowing up to 100% movement with zero adhesive and cohesive stresses. When Sealtite is in a 4:1 ratio it is impermeable to water.
