Key Features
-
Superior Adhesion: Specifically formulated to create an unbreakable bond with marble, granite, quartz, and terrazzo.
-
Optimal Consistency: The “Solido” (solid/paste) texture is buttery and non-sagging, perfect for vertical applications and filling deep cracks or chips.
-
Fast Curing: Minimizes downtime with a quick-setting formula that allows for rapid grinding and polishing shortly after application.
-
High Polishability: Once cured, the mastic mimics the natural gloss of the stone, ensuring repairs are virtually invisible.
-
Excellent Stability: Resistant to water, oils, and most common household chemicals.
