SILANE WB CONCENTRATE™

1 of 1 products in this brand
SILANE WB CONCENTRATE™ is a VOC compliant modified silane water repellent concentrate designed for dilution with fresh potable water at the jobsite. When diluted, SILANE WB CONCENTRATE™ may be applied to vertical and horizontal, dense and porous masonry surfaces. SILANE WB CONCENTRATE™ is solvent free and VOC compliant. Prepared solutions react with the silica in concrete and masonry in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that prevents water molecules from penetrating, while allowing free migration of water vapors. The chemical bonds formed in this process become an integral part of the substrate and provide long-term water repellent protection.

    Pretreatment For Paint
    Water can penetrate through most paints and coatings. This leads to damp substrates, blistering and peeling of paint. Pretreating concrete, masonry, or stucco with SILANE WB CONCENTRATE™ prior to painting keeps walls drier and extends the life of the paint. SILANE WB CONCENTRATE™ is compatible with most latex and other paints. But to assure compatibility between paint and pretreatment, a small test application is recommended. Note: Do not use a pretreatment or allow overspray on metal or other nonporous surfaces to be painted.
    Limitations

    Not intended for below-grade waterproofing. SILANE WB CONCENTRATE™ will leave a residue on non-porous substrates such as glass windows, metal frames and painted surfaces. Caution should be taken with specialty coated glass or plastic windows. Check compatibility before application. Protect materials which can be damaged by solvents. Do not apply when following conditions are present:

    • Ambient or surface temperature less than 50° F or predicted to fall below 50° F within 24 hours following application.
    • Rain within 72 hours prior to application or predicted within four hours after application.
    • Wet or frozen substrates.
    • High winds which could cause excessive overspray.
    • Application should be completed by qualified applicator with experience applying water repellents. Application equipment should be clean and free of foreign materials which could be dissolved and deposited on surfaces to be treated. Contact CPI for additional precautions and information on compatibility with specific materials.

    Technical Details & Test Data

    Installation

    Dilute with clean potable water. Mix well after dilution. Prepared solution should be applied within 24 hrs. after dilution. Recommended dilution rates shown below.

    Brick Masonry:
    Dense – Dilute 7 parts water to 1 part concentrate
    Porous – Dilute 4 parts water to 1 part concentrate

    Concrete:
    Dilute 9 parts water to 1 part concentrate

    Do not apply in temperatures <50º F. Best results are obtained by applying prepared solutions of SILANE WB CONCENTRATE™ on clean and dry substrates. All surfaces must be cleaned to remove all traces of dirt, dust, efflorescence, mold, salt, grease, oil, asphalt, laitance, curing compounds, paint, coatings and other contaminants. Acceptable surface cleaning methods include shot-blasting, sandblasting, water-blasting and chemical cleaners. If chemical cleaning agents are used, neutralize and wash off residues completely. Allow surface to dry at least 72 hours after water cleaning. Check with your Chemical Products Industries, Inc. representative to verify suitable cleaning methods, products and that the surface preparation is adequate.
    As a standard procedure, fresh concrete should be allowed to dry for 28 days before application. All repointing must be completed and allowed to cure at least 3 days. Concrete repair and replacement must be completed prior to application. Patching materials, caulking, sealing materials, traffic paint must be fully cured before applying prepared solutions of SILANE WB CONCENTRATE™. In addition; the actual amount of material that is used for each application is dependent on the absorptive capacity of the substrate.

    Before applying, it is recommended that preliminary tests be carried out to determine usage and to test the effectiveness of the treatment.
    Spray apply by low-pressure (150 psi maximum) pumping equipment with a wet fan type spray nozzle. Alternate methods include nap roller (1”) or by brush. Required application rate varies from 40 to 200 sq. ft. per gallon depending on surface texture and absorbency.

    Vertical Surfaces: Test small area before starting general application to assure desired results and coverage rates. Provide adequate ventilation.
    Apply in a flooding application, from the bottom up using a “wet-on-wet” technique so the material runs down 6 to 8 inches below the spray pattern. On highly porous surfaces such as architectural concrete block, allow the first application to penetrate for 3-5 minutes then reapply in the same flooding manner. Brush out drips or runs that do not completely penetrate the surface to ensure a uniform application.

    Horizontal Surfaces: Test small area before starting general application to assure desired results and coverage rates. Provide adequate ventilation.
    Apply prepared solution in a flooding application and keep surface wet for 3-5 minutes before completely penetrating the surface. Avoid puddling or ponding, brush or broom excess material until it fully penetrates the surface. If applicable, block all drains and use absorptive coverings to contain run-off of excess material. To avoid unnecessary clean-up, use soap and water to remove overspray as soon as possible. Caution: Over application of material on dense surfaces may cause darkening of surface.

    Dry Time: 2 to 4 hours depending on temperature and humidity. Protect from rainfall, minimum of 6 hours following treatment. Treated surfaces will require 3-5 days to gain optimal water repellency.

    Clean Up: Thoroughly rinse equipment with soap and clean water. Rinse thoroughly.

    Precautions: Fire hazards are eliminated since SILANE WB CONCENTRATE™ is water-based and does not contain combustible or flammable solvents. Respiratory protection is not required during normal use and handling. Please refer to the Material Safety Data Sheet for more detailed information.
