How long does International (AkzoNobel) Interprotect take to dry?
Short answer
Launch-ready plan
Weatherproof, in-water and underway are different dates
- Prepare and apply the Epoxy polyamide primer
- Keep it dry for the stated time
- Launch or use only after the stated cure
This product’s stated stages Quoted at 77°F
- Safe to touch1 hour
- Working time ends3 hours
Worth noticing: Working time is only 3 hours; the next stated stage, safe to touch, is 1 hour.
Common mistake: Launching on the first dry day; most marine products need the immersion time stated.
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 Epoxy polyamide primer directions for epoxy primer, undercoat, and marine primer; do not infer immersion readiness from touch-dry time.

About this product
A high-performance epoxy polyamide primer. Its data sheet leaves the 25°C overcoating cell blank, so the page gives only touch-dry and pot life at 25°C and points to the 5, 15 and 35°C overcoating figures in the question below.
Using this specific product
International (AkzoNobel) Interprotect is listed here as the Epoxy polyamide primer version for epoxy primer, undercoat, and marine primer. 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 Epoxy polyamide primer; related versions can use different timing.
- For epoxy primer, undercoat, and marine primer, pay particular attention to substrate preparation, temperature and water exposure.
- At 25°C (77°F).
How to check readiness
Check the immersion or launch milestone—not just touch-dry time. The data sheet gives a pot life of 3 hours. Touch only a hidden edge first; a dry surface can conceal a soft layer underneath.
Avoid this mistake
Launching too soon can expose an incompletely cured film continuously.
