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 Water-based antifouling directions for bottom paint and water-based antifouling; do not infer immersion readiness from touch-dry time.

About this product

A water-based antifouling for use on boats where solvent paints are a problem. The cold-weather penalty is steep on its data sheet: 24 hours before overcoating at 41°F against 4 hours at 73°F.

Using this specific product

Interlux Micron WA is listed here as the Water-based antifouling version for bottom paint and water-based antifouling. 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 Water-based antifouling; related versions can use different timing.
  • For bottom paint and water-based antifouling, pay particular attention to substrate preparation, temperature and water exposure.
  • At 73°F (23°C).

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.
