SikaTop®-144

Polymer-modified portland-cement coating

SikaTop®-144 is a polymer-modified, two-component, cementitious coating. Designed for use on concrete, mortar, and masonry substrates. Easily applied by brush, roller, or spray equipment. This fine-textured, abrasion resistant coating is used for protection against deicing salts and for damp-proofing/waterproofing.

  • Bond strength ensures superior adhesion.
  • Increases resistance of substrate to deicing salts.
  • No mix water needed, liquid co-polymer triggers special blend of cements, fillers, and admixtures.
  • Superior abrasion resistance.
  • No batching, factory proportioned unit ensures consistent composition and high quality. Non-flammable; low odor.
  • Easily applied to clean, sound substrates.
  • Approved for use in contact with potable water.
  • May be overcoated with Sikagard® protective coatings.

Usage

  • Use on grade, above, and below grade on concrete, masonry, and mortar.
  • Use on horizontal, vertical, and overhead surfaces, both interior and exterior.
  • Potable water tanks.
  • Use as a coating over newly repaired concrete to provide a monolithic/uniform appearance.
  • Use as a protective coating to reduce the affect of deicing salt on concrete.
  • Use as a protective coating for waterproofing, damp-proofing, and improved resistance to weathering.
 
  • Use on concrete and masonry substrates to improve abrasion resistance to foot traffic and light pneumatic-tire traffic.
  • Use to coat the backside of architectural curtain wall panels to prevent water intrusion from the outside.

As the temperature will affect the pot life, application temperature:

  • Above 73 °F (23 °C) will reduce the pot life and workability

  • Below 73 °F (23 °C) will extend the pot life and workability

Application steps

MIXING

  • All mixing must be done mechanically using a low-speed drill (400–600 rpm) and Sika paddle.
  • Place approximately 1/2 Component ‘A’ into a clean mixing container.
  • While mixing, slowly add all of Component ‘B’ and continue to mix until you achieve a uniform paste with no lumps.
  • Be sure to scrape down sides of the mixing container at this time.
  • Add remainder of Component ‘A’ and continue to mix until uniformly blended.

APPLICATION

  • SikaTop®-144 should only be applied over properly prepared surfaces with high-quality brushes, rollers, or “hopper-type’’ spray equipment.
  • Surface should be SSD prior to application.
  • Two coats are recommended for maximum performance.
  • Apply thoroughly mixed coating generously with loaded brush or roller.
  • Always finish off with light strokes blending back into coated area for uniform appearance.
  • For application in direct sun or on a hot substrate, pre-wet surface and allow surface water to dissipate before coating.
  • Refer to ACI 306 and 305 Guidelines when there is a need to place this product in cold & hot temperatures.

CURING TREATMENT

  • As per ACI recommendations for Portland cement concrete, curing is required.

  • Moist cure with wet burlap and polyethylene, a fine mist of water or Sika® Antisol®-250W*.

  • Curing compounds adversely affect the adhesion of following lifts of mortar, leveling mortar or protective coatings.

  • Moist curing should commence immediately after finishing. Protect newly applied SikaTop®-144 from direct sunlight, wind, rain and freezing.

*Pretest of curing compound is recommended.
