About this product

A two-part acrylic whose sheet is a six-step temperature ladder: cure takes 120 minutes at 41 to 50°F, 80 at 51 to 68°F, 40 at 69 to 77°F, 30 at 78 to 86°F, 20 at 87 to 95°F and 15 at 96 to 104°F. The sheet says painting is not typically recommended.

Using this specific product

Sika Sikacryl PowerSet is listed here as the Two-part fast-setting acrylic crack and joint sealant version for cracks and joints. For sealing a joint, the useful question is not simply whether the surface looks finished—it is whether the exact next-action milestone shown above has been reached.

Before you start

  • Confirm the package says Two-part fast-setting acrylic crack and joint sealant; related versions can use different timing.
  • For cracks and joints, pay particular attention to joint depth, tooling, ventilation and exposure to water.
  • Gel time is for mixed material at the highest temperature in the range. The ladder runs from 120 minutes at 41 to 50°F down to 15 minutes at 96 to 104°F.

How to check readiness

Probe an inconspicuous edge for a continuous skin and follow the stated water-exposure milestone. The sheet gives a gel time of 4 minutes for the 69 to 77°F range. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.

Avoid this mistake

Surface skin is not the same as through-cure, especially in a deep joint.
