Rainguard Micro-Seal™ Silane Siloxane Penetrating Water Repellent Sealer sets an industry standard for superior moisture protection. Used on new construction, infrastructure and remodel projects throughout the US and Worldwide, it’s tested to stop a 98 mph wind driven rain coming through a treated concrete, brick, block or stucco wall surface without changing the look or texture of the surface. Made from the best water repellent chemicals in the construction market, Micro-Seal is a blend of silanes and siloxanes trusted by architects, engineers and building owners looking for long lasting protection of unpainted, porous surfaces.

What makes Micro-Seal different? A proprietary ingredient called Micro-Lok™. This additive ensures a long lasting mechanical bond and creates a hydrophobic barrier not affected by weathering, salt, dirt, freezing temperatures, UV light and wind-driven rain.  Micro-seal is a penetrating sealer invisible after application as it penetrates completely below the surface.

It protects against damage from water, salt and freeze – thaw cycling that can cause cracks in a surface.  It also adds stain resistance to the treated surface for easier cleaning which is great for horizontal applications. Available in ready-to-use and concentrate and super concentrate formulations.
