Waterproofing Coating - 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, andbelow 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.

Product Information

12 months from date of production if stored properly in original, unopened and undamaged sealed packaging

Store dry at 40-95 °F (4-35 °C)

Component ‘A’ must be protected from freezing. If frozen, discard.

Component ‘B’ must be protected from moisture. If damp, discard.

Condition material to 60-75 °F before using.

Application

Application Information

Factory proportioned unit. Mix entire contents.

> 45 °F (7 °C)

> 45 °F (7 °C)

~ 4 hours

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

~ 30 minutes tack-free time

2 hours minimum between coats

Application Steps

• 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.

• 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.

• 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.
