Compressive Modulus

Flexural Strength

Tensile Strength

For crack repairs: A 10 mm x 10 mm x 2.6 m long crack may be filled

For spalled concrete repairs: A 100 mm x 100 mm x 25 mm surface may be repaired

Condition cartridges between 5 °C and 25 °C (41 °F and 77 °F) prior to use.

Remove the twist cap from the top of the cartridge. Reach into the opening at the top of the cartridge with 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. Component A is beige and component B is black. 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 grey appearance and consistency.

Note: 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. 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 pliers or a similar tool. Remove residues 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 dispensing and application procedures as described.

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

TOOLING & FINISHING

Finish flush and strike even with the existing surface using a dry putty knife or small pointing trowel.

OVER PAINTING

Cured Sika® PowerSet gap filler may inhibit certain types of paints and coatings from adhering adequately to its surface. Test for adhesion and compatibility in an inconspicuous location before committing to any paint or coating. Painting is not typically recommended. Sanding the surface will help providing a better bond.

CURE MECHANISM

Sika® PowerSet is a two-component polyester formulation requiring a static mixing nozzle to combine the ingredients fo a reactive chemical cure.

Clean all tools immediately after usage, before initial set. Uncured mortar can be removed immediately from installation tools and surfaces with a solvent such as acetone, MEK or xylene. Cured material can only be removed mechanically. Heating the product will help soften the material in order to ease clean-up.
