ARDEX IMPREGNATING TILE & MARBLE SEALER is a deep penetrating protective sealer developed to reduce water permeability and surface staining on porous tiles and natural stone surfaces. It is designed for use on unglazed floor tiles, terracotta, clay tiles, marble, stone, bricks, and similar porous substrates while maintaining surface breathability. The sealer enhances the appearance of tiles with a subtle glossy finish and helps improve long-term surface durability for both interior and exterior applications.
