About this product

The solvent-free sibling in Gaco's silicone line, written in metric first (13°C for the 4 hour dry). Its 4 to 48 hour recoat window and 24 to 48 hour wait for foot traffic are the same as S20, so the 2015 date is the real difference between the two sheets.

Using this specific product

Gaco GacoProEco Solvent Free 100% Silicone is listed here as the Solvent-free silicone roof coating version for roof 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 Solvent-free silicone roof coating; related versions can use different timing.
  • For roof 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. At 13°C (55°F).

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 says to recoat within 4 to 48 hours. 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.
