Sealex SX Silane-Siloxane Water Repellent | MATEX

Sealex SX is a high-performance, solvent-based penetrative sealer designed to protect concrete, masonry, and stone surfaces from water damage and staining. Formulated with advanced silane-siloxane resins, this single-component product penetrates deep into the substrate to create a hydrophobic barrier within the pores, effectively repelling liquid water while maintaining the surface's natural appearance and breathability.

Unlike film-forming coatings, Sealex SX does not alter the texture or color of the material. It allows moisture vapor to escape, preventing internal pressure buildup and reducing the risk of spalling or cracking. This makes it an ideal solution for exterior walls, foundations, and other structures exposed to harsh weather conditions.

• Single-component formula ensures easy application via spray, brush, or roller.
• Preserves the natural look and texture of the treated substrate.
• Helps prevent freeze-thaw damage and reduces the risk of mold and efflorescence.
