CURE MECHANISM Sika®

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

Cartridge, Ambient and Substrate Temperature	Gel Time*	Cure Time
-10 °C (ambient and substrate temperature only)**	60 min	360 min
0 °C to 4 °C (32 °F to 40 °F)	20 min	180 min
5 °C to 10 °C (41 °F to 50 °F)	12 min	120 min
11 °C to 20 °C (51 °F to 68 °F)	6 min	80 min
21 °C to 25 °C (69 °F to 77 °F)	4 min	40 min
26 °C to 30 °C (78 °F to 86 °F)	3 min	30 min
31 °C to 35 °C (87 °F to 95 °F)	2 min	20 min
36 °C to 40 °C (96 °F to 104 °F)	90 sec.	15 min

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

** Condition the product at 5 °C (41 °F) before applying at sub zero temperatures

How to Use
Surface Preparation
Cracks, small cavities and/or voids that occur in cementitious mortar, concrete or stucco substrates should be mechanically prepared to a clean, sound, dust-free condition. Extremely narrow (i.e. hair line) cracks and voids may need to be notched or routed. Dry substrate conditions are ideal, but damp conditions can be tolerated as long as the
cracks, cavities or voids contain no standing water. Substrate should be frost-free.

Mixing

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 ofthe 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 colour. ‘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 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.

Application

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.

Removal Important:

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.

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.

Limitations

Minimum recommended ambient and substrate temperature is 4 °C (40 °F).
Minimum application temperature: -10 °C (14 °F). Condition cartridge between 5 °C and 25 °C (41 °F and 77 °F) prior to use.
Maximum recommended ambient and substrate temperature is 41 °C (105 °F).
Fully-cured Sika® PowerSet is not a flexible material. Do not use in moving joints.
Not formulated to be an aesthetically pleasing product.
Do not apply over a wet, glistening surface. Substrates should be frost-free.
Material may stain porous substrates. Carry out tests on a small mock-up or in an inconspicuous location prior to proceeding with entire project.
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.
