  Product Description  
     
 

MasonrySaver 20-B Water Repellent for Concrete is a VOC compliant water repellent which contains an optimized 20% blend of silane and siloxane. This product has been specially formulated for use in "severe environment" situations, such as parking garages, where protection from extreme moisture and de-icing chemicals is required. This water-based blend penetrates concrete pores up to 1/4 inch or more depending on surface porosity and moisture content at the time of application. MasonrySaver 20B Water Repellent For Concrete reacts with the minerals in concrete in the presence of ultraviolet light and atmospheric moisture. This reaction forms strong permanent bonds beneath the surface and creates a hydrophobic zone that helps prevent water penetration, while allowing free migration of water vapors. The chemical bonds formed in the process allow MasonrySaver 20B Water Repellent For Concrete to become an integral part of the substrate and provide long-term water repellent protection.

MasonrySaver 20-B Water Repellent for ConcreteWhere to Use:
MasonrySaver 20B Water Repellent for Concrete can be used on most vertical or horizontal exterior, above-grade surfaces. It is ideally suited for concrete where maximum chloride ion protection is needed including: Architectural concrete; precast or cast-in-place, Mortars, Exposed Aggregate Products, Portland Cement, Stuccos, and Concrete Masonry Units.

Vertical Application:
Mix well before using. Test small area of surface before starting general application to assure desired results and coverage rates. Apply from bottom up using a low pressure sprayer (10-25 psi) with a fan type nozzle, or by roller with a minimum 3/8" nap. Set sprayer to produce a coarse stream; avoid atomization of the material. Flood surface until excess runs down six to eight inches below spray or roller pattern. For maximum penetration and desired coverage rates, a wet on wet application is recommended; retreat within three to five minutes after initial application. A wet treated surface may be agitated with a soft bristle scrub brush to ensure more even distribution and greater penetration. Protect all adjacent glossy surfaces, paint films, windows, plant life, asphalt-based materials, and all other non-targeted surfaces from overspray and rundown. Remove overspray from non-targeted surfaces immediately with soap and water. Apply to southern exposed areas during coolest part of day..

Horizontal Application:
Mix well before using. To ensure proper coverage, measure surface before treating and apply product with low pressure spray or deep nap roller. Pretest to measure material penetration rates. Apply a single flood coat using sufficient material so that the surface remains wet for two to three minutes before product penetrates. If additional material is required to reach desired coverage rate, a wet on wet application can be used. Avoid puddling or ponding; brush or broom to spread material to more porous area. 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.

What are the Coverage Rate(s):
Coverage rates will range from 80 - 150 square feet per gallon per coat of application depending upon surface porosity. When treating fluted, scored, and split-face block, allow for reduced coverage due to increased surface area.

When to Apply:
Surface and air temperatures should be a minimum of 40°F and a maximum of 100°F. for two hours following application.

How Long to Wait:
Dries to touch in one to two hours depending on temperature and humidity.

Equipment:
Pump-Up or Airless Sprayer.

What is a High Solids Silane Blend:
This high solids blend of mostly silane modified with other silicone resins offers a faster cure rate with more predictable results. It does not form a film and, as a result, offers excellent vapor transmission. Its small particle size gives excellent penetration and long-term durability. Ideally suited for highly alkaline substrates and has excellent chemical resistance.

Safety Precautions to Observe:
Proper safety procedures should be followed at all times while handling the product. Wear chemical resistant gloves and chemical splash goggles. 

Refer to the Material Safety Data Sheet for important health and safety information before use.
