Cling - Waterproof Brick & Masonry Sealer Gel

CLING: A WATERPROOFING GEL FOR VERTICAL CONCRETE, BRICK, AND MASONRY SURFACES

A revolutionary waterproofing gel that offers exceptional performance without sagging, running, or dripping. This innovative product penetrates deeply into vertical concrete, brick, and masonry surfaces, providing up to 25 years of durable protection.

The gel consistency of Cling is optimized for vertical applications, ensuring no material loss. Unlike traditional liquid sealers, Cling Masonry Gel "clings" to the substrate, allowing for deeper penetration and formation of an invisible hydrophobic barrier.

Cling's waterproofing capabilities keep surfaces dry, enhancing their "R-value" and thermal resistance. The breathable formula allows moisture vapor to escape without compromising the sealer's performance, preventing water damage and deterioration.

WITHSTANDS WIND-DRIVEN RAIN Cling effectively prevents moisture and water from penetrating porous brick and masonry substrates. Its hydrophobic properties resist rain, moisture, and organic growth, safeguarding against deterioration and water damage. Compared to liquid alternatives, Cling offers the longest service life.

EASY TO APPLY Easily applied using an 8-inch magimate brush or an airless sprayer, Cling can be used on a variety of concrete, brick, and masonry surfaces, both indoors and outdoors, on new and old construction.

DRIES INVISIBLE Cling Masonry Gel dries to a clear, invisible finish, preserving the original appearance of the treated surface. Although it goes on as a white gel, it will fully convert to a clear polymeric resin within 30-45 minutes, creating an effective and unobtrusive barrier.

APPLICATION PROCESS When applying Cling Masonry Gel, start from the bottom of the substrate and work upward, applying a 6-8 mil thick coating. Ensure to cover between bricks and into mortar joints. If using an airless sprayer, take care to protect surrounding surfaces from overspray.

The gel will initially appear white but will gradually become clear as the active particles absorb and react below the surface, forming an invisible hydrophobic barrier. Within 24 hours, the surface will typically return to its original appearance (some surfaces may take up to 7 days).

Water repellency and the "beading effect" may take up to 7 days to fully develop. Cling Masonry Gel can seal cracks up to 0.3 mm and can be painted or coated 7 days after application, improving the adhesion of paints and coatings.

PRODUCT DETAILS Cling Masonry Gel is a high-performing, 100% breathable, and non-film-forming waterproofing solution. It penetrates deep within the concrete, chemically reacting within the pores and capillaries to create a long-lasting hydrophobic surface that resists wind-driven rain, moisture intrusion, water, organic growth, and efflorescence.

The gel formula is optimized for vertical surfaces, ensuring no material loss. Cling is UV stable and will not break down with exposure to UV light, maintaining its clear, natural, and invisible finish.

Surface preparation, application methods, dry time, cleanup, and precautions are provided in the detailed product information. Cling Masonry Gel is designed for use on dry, porous masonry surfaces, and should not be applied below grade or on previously sealed or painted surfaces.
