MATEX Sealex SW Hydrophobic Water Repellent Sealer

MATEX Sealex SW is a high-performance, water-based penetrative sealer designed to protect concrete, masonry, and natural stone from water ingress and weathering. Utilizing advanced silane-siloxane technology, this hydrophobic sealer penetrates deep into the substrate to form a durable, moisture-repellent barrier within the pores of the material.

Unlike film-forming sealers, Sealex SW does not create a surface layer that can peel or chip. Instead, it works from the inside out, maintaining the natural breathability and aesthetic appearance of the surface while significantly reducing water absorption. This makes it an ideal solution for exterior walls, foundations, and exposed structural elements in harsh climates.

Key Features

• Water-based formula for easy application and low VOC emissions.
• Deep penetration creates long-lasting hydrophobic (water-repellent) protection.
• Preserves the natural look and breathability of concrete and masonry.
• Resists water, dampness, and salt crystallization damage.
• Enhances durability against freeze-thaw cycles and weathering.

Applications

• Exterior concrete walls and foundations.
• Masonry blocks, bricks, and natural stone facades.
• Industrial floors and exposed structural concrete.
