Frequently Asked Questions
Upon exposure to the air, Frame Mastic Sealant forms a tough, flexible skin which protects the bulk of the sealant from the hardening effects of drying out. If the skin is punctured or broken, the sealant below the surface forms a new skin.
Joint surfaces must be clean, dry, sound and free from dust, dirt, grease and other contaminants that may impair adhesion.
