Water Repellent Sealer
AF005 WRS is a single component water-based sodium methyl siliconate solution designed to impart water repellency to a wide variety of surfaces. The siliconate reacts with moisture and carbon dioxide in the air to form an insoluble water resistant resin.  This product offers low water absorption that is maintained for long periods of time. Even exterior applications with AF005 show little change in water repellency over a five to ten-year period.

BENEFITS OF USE:
Concrete sidewalks, drives or floors:
  • Increases durability by improving resistance to freeze thaw effects (horizontal surfaces that bear traffic will need to be retreated more often to maintain optimum performance)
  • Improves weathering and reduces efflorescence of natural stone, precast stone and ceramics.
  • Protects and fortifies concrete as it seals against moisture damage.
  • Product will not discolor or stain under normal use
  • Application of the AF005 will reduce dusting and increase concrete life

OTHER VARIOUS SUBSTRATES
TYPE OF MATERIAL % water exclusion
limestone                                                       67.0
sandstone                                                      79.5
concrete block                                                75.5

  • The percent water exclusion is based on and in comparison to an untreated control sample.
  • When properly used, this product can reduce water absorption while still maintaining greater than 50% breathability. (Details of these test procedures can be found in the ASTM standard C-67 and U.S. Federal Specifications SS-W-110C.)
