Using this specific product

Atlas Minerals Pool Putty is listed here as the Underwater epoxy putty version for pool spa. For repairing or coating a pool or spa, 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 Underwater epoxy putty; related versions can use different timing.
  • For pool spa, pay particular attention to surface moisture, film thickness and cure temperature.
  • At manufacturer-stated conditions; temperature, humidity and film thickness can change drying time.

How to check readiness

Check the longest stated immersion milestone before filling. Confirm the surface is dry and ready before continuing. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. Allow approximately 1 day before filling, subject to temperature and label directions.

Avoid this mistake

Dry-to-touch is not the same as ready for continuous immersion.
