About this product

A two-part aliphatic urethane that matches UA7090 on pot life and touch time but gives shorter waits afterwards: 24 hours for light foot traffic and 72 hours for chemical resistance. The sheet's own caveat is that the numbers assume good weather and no rain.

Using this specific product

Gaco GacoFlex UA60 is listed here as the Two-component aliphatic polyurethane coating version for urethane 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 aliphatic polyurethane coating; related versions can use different timing.
  • For urethane 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.
