FAQs
What is FS MASTIC LIQUID used for?
FS MASTIC LIQUID is a two-component polyester resin adhesive formulated for marble crack repair, granite bonding, and natural stone adhesive applications. Its liquid stone filler consistency makes it ideal for extensive surface repairs on both natural and engineered stones.
How do I mix FS MASTIC LIQUID with hardener?
Measure 1 to 4 g of liquid hardener per 100 g of mastic and blend thoroughly until uniform. Proper mixing ensures optimal adhesion strength, a consistent working window of 8–15 minutes, and reliable stone bonding performance.
How should I prepare the stone surface before application?
Ensure the area is clean, dry, and lightly abraded to remove dust and grease. Proper prep maximizes adhesion strength and durability for liquid stone filler, marble joint repair, and granite surface bonding.
How does FS MASTIC LIQUID differ from epoxy-based stone adhesives?
FS MASTIC LIQUID is a polyester resin adhesive in styrene, offering a faster 6–8 hour cure compared to epoxies. Its liquid-grade consistency flows easily into wide cracks and large surface areas, making it ideal for repairing marble countertops and bonding extensive natural stone.
Is FS MASTIC LIQUID suitable for interior and exterior applications?
Yes. Its mineral-reinforced polyester adhesive resists moderate moisture and temperature fluctuations, making it ideal for indoor marble repairs and covered outdoor stone cladding. Protect newly made repairs from direct rain until they are fully cured.
