Marine & RV

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 High-solids antifouling directions for bottom paint, antifouling, and boat hull; do not infer immersion readiness from touch-dry time.

About this product

The high-solids version of Micron CSC, with an older 2011 data sheet. Unlike the standard CSC, its times do change with temperature: 16 hours to immersion at 50°F, 8 hours at 77°F and 4 hours at 95°F.

Using this specific product

Interlux Micron CSC HS is listed here as the High-solids antifouling version for bottom paint, antifouling, and boat hull. 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 High-solids antifouling; related versions can use different timing.
  • For bottom paint, antifouling, and boat hull, pay particular attention to substrate preparation, temperature and water exposure.
  • At 77°F (25°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.
