SEALEX SX is a solvent-based, single-component penetrative sealer formulated with silane-siloxane resins for superior water repellence on concrete and masonry substrates. Designed for deep penetration, it effectively impregnates mineral and highly alkaline surfaces such as concrete, cement plaster, bricks, lightweight concrete, and porous stone façades. The breathable formula maintains vapor permeability while providing long-lasting protection without altering the surface’s appearance. SEALEX SX is highly resistant to UV exposure, weathering, and freeze-thaw cycles, making it ideal for challenging environments. Its durable, non-film-forming finish helps preserve surface integrity while reducing water intrusion and extending substrate life.
