Tetrion Stonefil is a versatile filler designed for repairing and restoring natural stone, ceramics, marble, slate, concrete, and brickwork. It provides a super smooth, pinhole-free finish and acts as a fast-setting, waterproof filler and adhesive. Suitable for a wide range of surfaces including marble, onyx, quartz, china, ceramic, brickwork, terrazzo, granite, slate, limestone, concrete, and sandstone. It can be mixed with a hardener for application as a filler or adhesive. Once set, it is resistant to temperatures from -20°C to 100°C. The filler can be overpainted or tinted with pigments, strainers, or stone dust before the hardener is added. For best results, use in temperatures between 5°C and 30°C. Clean tools with cellulose thinners before the paste sets.
