Water-exposure plan

Splash, filling and continuous immersion are not equivalent

Brief moisture

Splashes or dampness can use a different milestone.

Continuous water

Filling, launching or immersion requires the exact water milestone.

Use the Ablative bottom paint directions for boat and marine; do not infer immersion readiness from touch-dry time.

Using this specific product

Interlux Micron 66 Antifouling is listed here as the Ablative bottom paint version for boat and marine. For repairing marine or RV equipment, 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 Ablative bottom paint; related versions can use different timing.
  • For boat and marine, pay particular attention to substrate preparation, temperature and water exposure.
  • Substrate temperature.

How to check readiness

Check the immersion or launch milestone—not just touch-dry time. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath. Before recoating, confirm the first coat matches the manufacturer’s stated condition; if the maximum window passed, check whether sanding is required. Continuous immersion is more demanding than splashes; wait for the specific immersion milestone.

Avoid this mistake

Launching too soon can expose an incompletely cured film continuously.
