Armor SX5000 WB
The Armor SX5000 WB is a professional-grade water-based silane siloxane concrete sealer for unsealed concrete, brick, pavers, bluestone, flagstone, slate, and other natural stone. It penetrates the substrate and chemically reacts to form a long-lasting water-repellent barrier below the surface that reduces the absorption of water and other liquids by up to 95%. The Armor SX5000 WB silane siloxane sealer helps to reduce damage caused by water absorption, snow and ice, and road salts.
- PROFESSIONAL GRADE SILANE SILOXANE SEALER: The Armor SX5000 WB is a professional-grade water-based silane siloxane sealer designed for use on unsealed concrete, brick, paver, bluestone, flagstone, slate, natural stone, and masonry.
- REDUCES WATER ABSROPTION BY UP TO 95%: The Armor SX5000 WB chemically reacts to form a water-repellent barrier below the surface that will reduce the absorption of water and other liquids by up to 95%.
- WON’T CHANGE THE LOOK OR COLOR: Formulated with high-quality US-manufactured resins, the Armor SX5000 WB is designed to protect your concrete, brick, pavers, stone, and masonry without changing the look, color, or feel. Your substrate will look and feel exactly as it did before it was sealed!
- LONG LASTING PROTECTION: The Armor SX5000 WB Silane-Siloxane concrete sealer chemically reacts to form a water-repellent barrier below the surface that can last for up to 7-10 years. By reducing the absorption of water through the surface, damage caused by water absorption is also reduced. Sealed surfaces are more resistant to cracking, spalling, ice damage, salt damage, organic surface growth, and staining.
- READY TO USE: The Armor SX5000 WB is ready-to-use and can be applied to a properly cleaned and prepped unsealed surface with pump sprayer. One gallon covers up to 175-225 square feet per gallon. Foundation Armor cleaners and sprayers are available separately.
- EASY TO MAINTAIN: The Armor SX5000 WB works entirely below the surface so there is no surface film or coating to maintain. When it is time to reseal, simply apply 1-2 coats of the Armor SX5000 WB to a clean, dry, and absorbent surface with a pump sprayer.
- WATER BASED FORMULA: The Armor SX5000 WB is water-based. It is easy to use, 0 VOC, and has no odor. Clean-up is quick and easy, and can be done with soap and water.
