Sure Klean® Weather Seal Siloxane WB Concentrate is a solvent-free blend of silanes and oligomeric alkoxysiloxanes that mixes easily with fresh water on the job site to produce a penetrating water repellent ideal for application to dense or porous masonry surfaces.

An effective alternative to conventional solvent-based silanes or siloxanes, Siloxane WB penetrates and chemically bonds deep within the masonry substrate to provide long-lasting protection against water-related staining or deterioration. Siloxane WB will not darken, produce a surface film or impair the natural breathing characteristics of treated surfaces.

ADVANTAGES

• Treated surfaces “breathe” – does not trap moisture.

• Concentrate minimizes storage, transport and container disposal requirements.

• Mix with up to 19 parts fresh water. One gallon concentrate treats up to 4,000 square feet.

Consult coverage rates.

• Alkaline stable – suitable for new concrete.

• Penetrates deeply – effective on vertical or horizontal surfaces.

• Resists water penetration when applied over existing shrinkage cracks of 0.02 inches or less.

• Ideal for field or in-plant treatment of precast concrete.

Limitations

• Product must be applied within 24 hours of dilution for maximum effectiveness.

• Not appropriate for use on limestone, marble, travertine or other calcareous stones. Always test other natural stone to ensure desired results.

• Will not prevent water penetration through structural cracks, defects or open joints.

• Not recommended for below-grade application.

REGULATORY COMPLIANCE

VOC Compliance Sure Klean® Weather Seal Siloxane WB Concentrate is compliant with the US Environmental Protection Agency’s AIM VOC regulations.

Visit www.prosoco.com/voccompliance to confirm compliance with individual district or state regulations.

PREPARATION

Protect people, vehicles, property, plants, windows and all surfaces not set for treatment from product, splash, residue, fumes and wind drift. Use polyethylene or other tested material for protecting non masonry surfaces. Protect/divert pedestrian and auto traffic.

Ensure fresh air entry and cross ventilation during application and drying. Extinguish all flames, pilot lights and other potential sources of ignition during use and until all vapors are gone.

When applying to exteriors of occupied buildings make sure all windows, exterior intakes and air conditioning vents are covered and air handling equipment is shut down during application and until vapors have dissipated.

Surface should be clean, dry and absorbent.

Excessive moisture inhibits penetration and reduces the service life and performance of the treatment. If necessary, thoroughly clean the surface using the appropriate PROSOCO product.

Newly constructed and repointed surfaces should be clean, dry and thoroughly cured before application.

Sealing and caulking compounds should be in place and cured.

The top of walls need to be capped and made watertight prior to application.

Surface and Air Temperatures Surface and air temperatures must be at least 40°F (4°C) during application and for 8 hours following.

If freezing conditions exist before application, let masonry thaw. Subfreezing temperatures will cause Siloxane WB to freeze or crystallize, which inhibits penetration and impairs results.

Surface and air temperatures should not exceed 90°F (32°C). Higher temperatures cause rapid evaporation of water carrier and result in reduced penetration.

Equipment Recommended application is by high volume, low-pressure (<50 psi) spray. Fan spray tips are recommended to avoid atomization. Do not atomize/ vaporize the material.

For small scale application, or when spray application is not appropriate, product may be applied using brush or roller. Contact Customer Care or your local PROSOCO representative for more information.

Storage and Handling Store in a cool, dry place away from potential ignition sources. Keep tightly sealed when not dispensing.

APPLICATION

Read “Preparation” and the Safety Data Sheet before use.

ALWAYS TEST a small area of each surface to confirm suitability, coverage rates and desired results before starting overall application. Include in the test area any previous repairs and patches, including aesthetic cementitious finishes.

Different surface compositions may result in absorption and/or appearance differences. Test with the same equipment, recommended surface preparation and application procedures planned for general application.

Dilution & Mixing Dilute with clean, potable water only. Mixing vessels must be clean, dry and free of contaminants. When added to water, Siloxane WB turns milky white. Mix lightly to produce a uniform consistency.

One gallon of Siloxane WB concentrate produces up to 20 gallons of water repellent (on dense vertical surfaces). Always test for most appropriate coverage rates.

Siloxane WB is most effective when prepared solutions are applied within 8 hours of dilution, and must be applied within 24 hours of dilution.

Vertical Surfaces

• Porous: 1 part concentrate : 9 parts water

• Semi-porous: 1 part concentrate : 14 parts water

• Dense: 1 part concentrate : 19 parts water

Horizontal Surfaces

• Porous: 1 part concentrate : 7 parts water

• Semi-porous: 1 part concentrate : 9 parts water

• Dense: 1 part concentrate : 14 parts water* *A maximum dilution of 1 part concentrate to 9 parts water is required to qualify for an extended horizontal warranty.

Application Instructions For best results, apply “wet-on-wet” to a visibly dry and absorbent surface.

Vertical Surfaces: Spray Application

1. Apply in a saturating application from the bottom up using enough material to create a 4–8 inch

(15–20 cm) rundown below the spray contact point.

NOTE: When spray applying to fluted architectural block, spray in an “overlapping X pattern” for complete coverage of recessed surfaces.

2. Let the first application penetrate the masonry surface for 2 to 3 minutes.

3. Reapply in the same saturating manner.

Less material will be required for the second application.

BEST PRACTICES

Surface should be clean, dry and absorbent.

Excessive moisture inhibits penetration and reduces the service life and performance of the treatment. If necessary, thoroughly clean the surface using the appropriate PROSOCO product.

Ensure fresh air entry and cross ventilation during application and drying. Extinguish all flames, pilot lights and other potential sources of ignition during use and until all vapors are gone.

When applying to exteriors of occupied buildings make sure all windows, exterior intakes and air conditioning vents are covered and air handling equipment is shut down during application and until vapors have dissipated.

The top of walls need to be capped and made watertight prior to application.

Recommended application for PROSOCO protective treatments is high volume, low-pressure (<50 psi) spray equipment. Fan spray tips are recommended to avoid atomization. Do not atomize/vaporize the material.

For small scale application, or when spray application is not appropriate, brushes or roller may be used. Contact Customer Care or your local representative for more information on brush/roller application.

Dilute with clean, potable water only. Mixing vessels must be clean, dry and free of contaminants. When added to water, Siloxane WB turns milky white. Mix lightly to produce a uniform consistency.

Vertical Surfaces: Brush/Roller Application Recommended for small scale application or when spray application is not appropriate. Contact PROSOCO for more information. Apply uniformly.

Use enough material to saturate the surface. Let penetrate the masonry surface for 2 to 3 minutes.

Brush out heavy runs and drips that do not penetrate.

Horizontal Surfaces Apply in a single saturating application. Apply enough to keep the surface wet for 2 to 3 minutes before penetrating. Broom out all puddles until they penetrate the surface.

Dense, Smooth Surface Application Apply in a single coat using enough to completely wet the surface without creating drips, puddles or rundown. Brush out or back roll all runs and drips for uniform appearance. Do not over apply. Over application may cause unacceptable color change.

One application is normally enough. Always test for application rate.

Drying Time Treated surfaces will dry to touch within 1 hour.

Protect surfaces from rainfall for a minimum of 4 hours following treatment. Protect from foot and vehicle traffic until visibly dry. Surfaces may require as many as 72 hours to gain their water repellency properties.

Paint Adhesion Treated surfaces may be coated with most silicone emulsion and many oil-based paints. Always test to assure adhesion. Adhesion may be improved if surface is pressure rinsed and allowed to dry before application.

Adhesion of some cementitious coatings, plaster, stucco, etc., may be adversely affected. Such surface treatments should be installed and allowed to thoroughly cure before installation of Siloxane WB.

Always test to verify compatibility between Siloxane WB and other proposed surface treatments.

Cleanup Clean tools and equipment immediately with soap and warm water.
