About this product

A clear two-part urethane topcoat with a 20 minute pot life, so the mixed batch has to go down quickly. It touches dry in 20 to 30 minutes but takes 48 hours for light foot traffic and 96 hours for chemical and solvent resistance, a long tail after a short set.

Using this specific product

Gaco GacoFlex UA7090 is listed here as the Two-component clear aliphatic polyurethane version for clear topcoat. For coating or sealing a roof, 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-component clear aliphatic polyurethane; related versions can use different timing.
  • For clear topcoat, pay particular attention to roof temperature, dew, rain in the forecast, film thickness and how many coats are needed.
  • At 70°F (21°C).

How to check readiness

Check that the surface is dry and that no rain or dew is forecast inside the stated window. The data sheet gives a pot life of 20 minutes. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Try a protected edge first and avoid turning, dragging or concentrated loads.

Avoid this mistake

Rain resistance and walkable are earlier milestones than the full cure the roof system is rated for.
