Water Repellent Treatments – Vertical Surfaces

Water ruins expensive masonry

Durable and beautiful though it is, over time, simple rainwater can visibly decay and stain unprotected concrete, brick and stone.

Rainwater soaks into masonry. It dissolves natural salts that re-crystallize when the surface dries. The salts build up in the masonry pores from repeated wet/dry cycles. In cold weather, water freezes and expands inside the masonry pores. At first, the cracks and fractures from wet/dry and freeze/thaw cycles are microscopic. They don't stay that way.

Combined with other natural forces, such as extreme temperatures and biological growth, this progressive decay can turn an expensive masonry investment into an eyesore and liability.  

Water subjects unprotected masonry to:

• Cracking, spalling and delamination
• Damp walls
• Efflorescence
• Mold, moss and lichen growth
• Lime run
• Corrosion from acid rain
• Rust stains
• Reduced thermal insulation

Stop water damage
Step 1: Fix the obvious problems.
These repairs stop direct water flow into the masonry.

• leaky gutters and downspouts
• failed flashing
• faulty roofing and caulking
• cracks in the masonry

Step 2: Protect the masonry with a high-quality water repellent.
When water can't invade the masonry, neither can any of the previously described problems. Protective treatments let the beauty and value of masonry investments endure.

Sure Klean^® Weather Sealpenetrating water repellents provide an invisible, breathable shield against the water-related enemies of masonry. It's protection that lasts -- in most cases, 10 to 15 years.

Sure Klean^® Weather Seal Siloxane PD
A ready-to- use, water-based silane/siloxane water repellent. Designed for use on concrete and masonry surfaces, Siloxane PD penetrates more deeply than conventional water or solvent-based water repellents. Low odor and alkaline stable, Siloxane PD is ideal for field or in-plant application to color-sensitive concrete, GFRC, most masonry and stucco surfaces. Application equipment, window glass and areas affected from overspray are easily cleaned with soap and water.

Sure Klean^® Weather Seal Siloxane WB Concentrate
A self-emulsifying water repellent concentrate designed for dilution with fresh water at the jobsite. This solvent-free blend of silanes and oligomeric alkoxysiloxanes mixes easily with water to produce a penetrating water repellent ideal for application to dense or porous masonry surfaces. Weather Seal Siloxane WB can also be used as a primer to even out porosity and improve adhesion of BMC^® Breathable Masonry Coatings.

Sure Klean^® Weather Seal GP
An economical, ready-to-use, low odor and alkaline stable water-based silane/siloxane water repellent for concrete, stucco, and most masonry surfaces.  Helps masonry resist cracking, spalling, staining and other damage related to water intrusion.

Sure Klean^® Weather Seal SL100 Water Repellent
Complies with all known regulations limiting the Volatile Organic Compound (VOC) content of architectural coatings and sealers.

Sure Klean^® Weather Seal Natural Stone Treatment
A general purpose siloxane water repellent developed for limestone, marble and most other traditional masonry surfaces. Natural Stone Treatment penetrates deeply to provide long-lasting protection without altering the natural appearance of the substrate.

Sure Klean^® Weather Seal Natural Stone Treatment WB
An odorless, water-based solution of potassium methyl siliconate developed to effectively treat a wide range of natural stone and masonry surfaces that provides long-lasting repellency without altering the natural appearance of the substrate.

Sure Klean^® Weather Seal Natural Stone Treatment
A general purpose siloxane water repellent developed for limestone, marble and most other traditional masonry surfaces. Natural Stone Treatment penetrates deeply to provide long-lasting protection without altering the natural appearance of the substrate.

Sure Klean^® Weather Seal H40
Formulated as a deep-penetrating water repellent and consolidation treatment for brick, most natural stone, terra cotta, historic concrete, stucco and cast stone surfaces. H40 protects against deterioration caused by water and water-borne contaminants while strengthening weathered surfaces and soft mortar joints.

Sure Klean^® Weather Seal Blok-Guard^® and Graffiti Control
A clear, solvent-based silicone elastomer formulated to weatherproof concrete block and other porous masonry materials. Blok-Guard^® and Graffiti Control protects masonry surfaces from repeated graffiti attacks without altering the natural appearance.

Sure Klean^® Weather Seal Blok-Guard^® and Graffiti Control II
A clear-drying, water-based silicone emulsion for weatherproofing concrete block and other porous masonry materials.

Sure Klean^® Custom Masonry Sealer
A clear, solvent-based silicone elastomer formulated to weatherproof custom masonry units, cast stone, architectural concrete block, precast concrete, wood and porous masonry without altering the natural appearance. Custom Masonry Sealer penetrates and fills pores to prevent water penetration through exterior walls exposed to normal weathering.

Sure Klean^® Burnished Block Sealer
A water based acrylic emulsion for protecting and enhancing the finish of burnished concrete block. Applied with brush, roller or low-pressure sprayer, this milky-white liquid dries quickly to a tightly adhered glossy finish providing resistance to the scrapes and scuffs of transport and facilitates the removal of mortar smears and other construction soiling.  A treatment following construction cleaning enhances the appearance of burnished block and makes maintenance cleaning easier.
