About this product
The only page-sourced Gaco entry in this batch: the numbers come from the product page, not a data sheet. It gives 10 to 12 hours between coats and walkable within 24 hours, with no tack-free or rain figures, so treat it as a planning guide.
Using this specific product
Gaco GacoFlex U91 is listed here as the Aromatic urethane coating version for urethane coating. 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 Aromatic urethane coating; related versions can use different timing.
- For urethane coating, pay particular attention to roof temperature, dew, rain in the forecast, film thickness and how many coats are needed.
- The source gives no conditions for this time.
How to check readiness
Check that the surface is dry and that no rain or dew is forecast inside the stated window. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. 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.
