Audited Supplier Silway 714 water repellent is a water-dilutable solution of potassium methyl siliconate designed to impart water repellency to a wide variety of surfaces. Supplied at a concentration of 52 percent in water.
Silway 714 water repellent is usually diluted to a concentration of 3 percent or less before application.
Silway 714 water repellent reacts with carbon dioxide in the air to form an insoluble water-resistant treatment within 24 hours.

* Reduces water absorption into the substrate, thus reducing spalling due to freeze-thaw and efflorescence,
thereby increasing the life of the substrate
* Colorless and non-yellowing protection preserves the natural appearance of the substrate
* Penetrating and breathable
* Low VOC
* Nonflammable
* As a surface treatment in applications that utilize its ability to impart a water repellent surface
and reduce water absorption
* For use on bricks, sandstone, limestone, and ceramics
As a surface treatment Silway 714 is diluted to a concentration of 3 percent solids or less prior to application.
Do not use concentrations higher than 3 percent solids unless prior testing indicates a necessity. The use of higher concentrations than required may result in the formation of a white residue on the surface. Users should test the concentration to be applied on the substrate prior to use.
After application of the silicone solution, allow the treated surface to dry for at least 24 hours to develop maximum water repellency. This interval may be shortened somewhat by force-drying at temperatures up to 175°C. While this removes the water quickly, time must be allowed for the curing reaction between Silway 714 and the surface being treated. Carbon dioxide streams do not appear to reduce the cure time appreciably.
