Tephra Stone is a colorless waterproofing applied to a large variety of materials, especially waterproof materials on porous surfaces, such as concrete, plaster and stone. Tephra Stone has excellent water resistance, reduces water absorption in the substrate, reduces freeze-thaw cracks and efflorescence, thus increasing the life of the substrate. “Colorless protection, maintains a natural appearance, and keeps the substrate permeable and breathable

Tephra Stone

Colorless waterproof insulation with nano technology comes ready for direct use Without the need for any additions. Tephra Stone was developed with a group of materials that work to form an insulating layer Closing the pores on stone and concrete facades prevents water absorption Maintain color. Tetra Stone interacts with the air and forms a protective, non-removable layer Colorless protection that preserves the natural appearance of the stone
