APS-236 Emulsion

Waterborne, organo-modified siloxane emulsion designed for use as a penetrating and durable water repellent for concrete, split-face block, brick, natural stone etc. Rejuvenates the color and appearance of worn and weathered surfaces.


  • Superior water repellency for various substrates.
  • Low dilution levels required for maximum performance.
  • Chemically bonds to the treated substrate preventing potential
    damage from repeated freeze/thaw cycles.
  • Excellent storage stability. Freeze/thaw stable and elevated
    temperature (50oC) stable.
  • No change or slight change in surface appearance
  • Can be used in admixtures for cementitious products


  • Substrate should be clean and free from any contaminants (dust,
    dirt, oil, grease, curing compounds, paint/coatings, efflorescence,
    etc.) before applying APS-236 Emulsion.
  • Dilute product to 5—10wt% depending on the intended use in
    water (preferably de-mineralized) and stir at low shear.t
  • Two coats of the dilution should be applied wet-on-wet
    (approximately 15—20 minutes in between coats) to ensure the
    best coverage. Do not allow second coat to pool or puddle on
    treated surface.
  • APS-236 Emulsion can be applied by brush, roller, spray or dip.
  • A minimum of 24 hours should be allowed before treated surface
    comes in contact with water. Maximum water repellency will
    occur approximately 48—72 hours after application, depending
    on the curing conditions.
