- 40% silane; One component for ease of application
- Long-lasting penetration protects against moisture and chloride intrusion
- Chemical bonding for long-lasting protecting against damaging moisture
- Does not change concrete surface appearance by forming a film or glossy enhancement
- High degree of vapor transmission; Treated surfaces “breathe” – does not trap moisture
- Easy to apply. No premixing or special equipment required.
- Improved durability against freeze-thaw cycles and deicing salt stress
- Reduces efflorescence, mildew and atmospheric staining
- Forms an effective chloride screen that reduces surface erosion and corrosion of rebar in reinforced concrete caused by water and water-carried salts
- Ideal for use on concrete surfaces subjected to vehicle traffic
- Appropriate for use on the following concrete substrates: Architectural Precast Panels, Glass-fiber-reinforced Cast-in-Place Pavers, Cast stone, Manufactured stone
- Resists water penetration when applied over existing shrinkage cracks of 0.02 inches or less
- Suitable for sale in most states and districts with more restrictive AIM VOC regulations

Concrete Silane WB 40
water-based 40% silane emulsion for concrete
Description
This ready-to-use, high-grade silane water repellent provides resistance against the damaging effects of water intrusion, freeze-thaw cycles, and chloride intrusion. Unlike conventional coatings and sealers, Concrete Silane WB 40 penetrates completely and reacts to form a chemical bond within the substrate. Treated surfaces retain their natural color, texture, appearance, and vapor permeability.

PRODUCT SUPPORT
OVERVIEW
PROSOCO® Concrete Silane WB 40 is a water-based, 40% silane emulsion, penetrating water repellent for concrete. This ready-to-use, high-grade silane water repellent provides resistance against the damaging effects of water intrusion, freeze-thaw cycles and chloride intrusion. When properly applied, Concrete Silane WB 40 provides exterior horizontal and vertical concrete resistance against water and waterborne contaminants. Depth of penetration is controlled by the application (loading) rate.
Unlike conventional coatings and sealers, Concrete Silane WB 40 penetrates completely and reacts to form a chemical bond within the substrate. A water repellent barrier is formed without a surface film or gloss. Treated surfaces retain their natural vapor permeability. Treatment with Concrete Silane WB 40 will not entrap damaging moisture within the concrete or masonry surface. In addition, treated surfaces retain their natural color, texture, and appearance.
