How long before you can recoat Interlux Epoxy Primekote?
Short answer
Water-exposure plan
Splash, filling and continuous immersion are not equivalent
Splashes or dampness can use a different milestone.
Filling, launching or immersion requires the exact water milestone.
Use the Two-part epoxy primer directions for boat and marine; do not infer immersion readiness from touch-dry time.

Using this specific product
Interlux Epoxy Primekote is listed here as the Two-part epoxy primer 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 Two-part epoxy primer; 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.
Avoid this mistake
Launching too soon can expose an incompletely cured film continuously.
