While both mastic and glue are adhesive substances used to bond materials together, they possess distinct physical properties and specialized applications. Glue is typically a liquid, solvent-based or water-based adhesive engineered to penetrate tight joints and form a rigid, high-tensile bond between two solid surfaces. Mastic, on the other hand, is a thick, viscous, paste-like adhesive specifically designed with high initial grab and body, allowing it to hold heavy items like ceramic tiles, drywall sheets, or flooring materials securely in place on vertical or horizontal surfaces without sagging.
