Using this specific product

Sika SikaBond Construction Adhesive is listed here as the Polyurethane version for subfloor, wood, and concrete. For bonding parts, 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 Polyurethane; related versions can use different timing.
  • For subfloor, wood, and concrete, pay particular attention to surface fit, cleanliness, clamping pressure and bond-line thickness.
  • 73°F and 50% RH; depends on temperature and humidity.

How to check readiness

Test a noncritical offcut or wait for the stated load milestone before stressing the joint. Skin time: 2 hours. Reserve full cure for demanding use, chemicals, washing, immersion or load—not merely gentle handling.
