Sikacryl PowerSet is a two component polyester formulation requiring a static mixing nozzle to combine the ingredients for a reactive chemical cure.

* Gel Time is the typical amount of time for mixed Sika PowerSet to solidify at highest temperature in the range
Consumption

Coverage

Each cartridge will yield approximately 9-1/2 linear feet (2.9 m) of mixed material when filling a typical 3/8 in. wide by 3/8 in. deep (10 mm x 10 mm) gap (e.g. mortar joint)
Application steps

MIXING

  • Remove the twist cap from the top of the cartridge.
  • Reach into the opening at the top of the cartridge with a pliers or similar tool and pull the top of the plastic film upwards to reveal a metal retaining clip.
  • Cut the plastic film open below the metal retaining clip with a utility knife.
  • Ensure that both components within the plastic film are free to flow prior to inserting cartridge into a standard, good quality caulking gun. ‘A’ component is Beige in color. ‘B’ component is Black in color.
  • Attach the static mixing nozzle.
  • Begin dispensing the cartridge’s contents through the static mixing nozzle. Prior to installation, the initial portion of material dispensed from the nozzle is discarded until it can be visually verified that both components are flowing and mixing to a uniform Gray appearance and consistency.
  • If cartridge is partially used and the remaining contents is to be saved for a future application, leave the static mixing nozzle mounted on the cartridge until that later date. When ready to continue use, remove the spent static mixing nozzle by twisting counterclockwise and breaking the seal of the cured mortar. This may require the assistance of a pliers, wrench or similar tool. Remove remnants of cured mortar with a utility knife from the top of the openings in the plastic film to ensure fresh material is free to flow. Attach a new static mixing nozzle and repeat the dipensing and application procedures.

APPLICATION

After confirming that a well blended mix is being dispensed from the static mixing nozzle, fill the prepared crack, cavity or void with Sikacryl® PowerSet gap filler.

  

Tooling and Finishing
