Antifouling drying time

[killick]

I will be antifouling my Sadler 26 with Jotun seaforce 30.Due to tides i have a choice of putting it back within 48 hours[24 hours drying time] or to let it dry for 14 days.Wil the longer drying time result in better or poorer performance? Any advice will be appreciated.

I very much doubt if it will make any significant difference - but the 48 hour option gives you 2 weeks extra sailing time, much more important!

Just looked up the data sheet for you. Using the 10 degrees column for hull temperature (it might be warmer than 10, but the time doesn't change significantly till it gets really hot) this says 9 hours before applying a second coat and then anywhere from 12 to 22 hours before it's dry enough to launch. This is for serious sue-for-millions-if-it-doesn't-work application on container ships, so I'd be inclined to trust it. Although I doubt many yachties follow the rules for drying time between coats.

Last time if did AF it was drying on the roller! Some AF paint lets you launch within a few minutes, so you can paint the bits under the props.

It always pays to check the manufactures recommendations, but the paint I slap on just before launching to cover the areas where the pads have been seems just as effective as the rest, especially considering it gets fewer coats.

I've used Jotun SeaGuardian and SeaQueen - both dry much quicker than it says. I queried it - the figures given relate to heavy application by airless spray, not the amount you can get on with a roller.

Takes a long time to antifoul big ships, which Seaforce is designed for. 14 days not a problem, I've left ours for over a month in hot temperatures and it works fine.
