About this product

A polyurethane sealant with a 2 hour skin time and 6 to 8 hours to tack-free. Its sheet pairs a 40 to 100°F application range with a service range from -40 to 180°F, which is the number that matters for exposed joints.

Using this specific product

Tremco Dymonic 100 is listed here as the High-performance polyurethane sealant version for joint sealing. 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 High-performance polyurethane sealant; related versions can use different timing.
  • For joint sealing, pay particular attention to joint depth, tooling, ventilation and exposure to water.
  • The source gives no conditions for this time.

How to check readiness

Probe an inconspicuous edge for a continuous skin and follow the stated water-exposure milestone. The data sheet gives a skin time of 2 hours. The data sheet gives a tack-free time of 6 to 8 hours.

Avoid this mistake
