Using this specific product

Loctite (Henkel) Polyseamseal Painter's Caulk is listed here as the White version for trim, baseboards, and crown molding. 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 White; related versions can use different timing.
  • For trim, baseboards, and crown molding, pay particular attention to joint depth, tooling, ventilation and exposure to water.
  • Depends on temperature, humidity, porosity and depth of sealant. Bead size 1/4 in. 78°F and 50% RH.

How to check readiness

Probe an inconspicuous edge for a continuous skin and follow the stated water-exposure milestone. Tack-free time: 10 to 20 minutes. Can be painted with latex paint or primer in 60 minutes. Test the seam or finish at the least-ventilated spot before normal water exposure.

Avoid this mistake

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