FAQ
For exterior use only — The product emits a strong smell. If to be used in areas such as interior foundation walls, basements, garage slabs, etc., make sure to have sufficient ventilation installed in the work area.
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 provide a better bond.
Clean all tools immediately after usage, before initial set. The 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 to ease clean-up.
- 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. ‘A’ component is beige. ‘B’ component 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.
- 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.
Dry substrate conditions are ideal, but damp conditions can be tolerated as long as the cracks, cavities or voids contain no standing water.
Do not apply over a wet, glistening surface. Substrate should be frost-free.
Sika® PowerSet is a two-component polyester formulation requiring a static mixing nozzle to combine the ingredients for a reactive chemical cure.
