Minimum outside temperature for bottom painting?

So I'm taking a stab at bottom painting this year. We plan to haul out sometime in April. Outside temperature will probably be toasty: mid 40's to low 50's (bikini weather), possibly with a chance of rain or snow (snowed 12 inches last April 14th!), but its usually drier than summer. So just a quick question: Is there a minimum temperature for bottom painting for the paint to properly adhere to the vessel? I've heard the stuff dries pretty fast, but I know that low temperatures tend to make things dry/set longer. Also, will a quick rain/snow completely ruin a paint job if it doesn't set quickly? That paint doesn't come cheap, nor does the haul out. Thanks for the input. This group totally ROCKS for us newer Cal owners.

Always refer to the paint manufacturer's directions... they should be on line.

Hi, ??? Don't know your name or the flavor of your boat or your location. But anyway... The painting thing has a lot of hooks. Most paints will set minimum temp at 40 or 50 F. Recoat times go way up as temp drops. If it gets wet before new coat, wait till dry. Are you going with hard paint or ablative? Kinda depends on where you are, what kind of sailing you do, and how much bottom scrubbing/wiping you do (or have done for you). If you take a instruction recommendation to use Interlux 202, get e REALLY good respirator/filtered mask. The stuff evaporates very quickly and can knock you on your butt. If you are using no sand primer, be careful to observe what paints you can't use over it. And remember the no sand cannot be completely dry before you do first coat of bottom paint. All kinds of stunts and tools for bottom sanding. Be careful to follow instructions so your beautiful bottom job does not start to peel off in a few months. Also, some paints have a specification of how soon the boat has to go in the water after painting. You're going to have a ball !

I would take that one step further and recommend that you contact the manufacturer. They may have more information that they are not publishing on the datasheets. I was doing some bottom work last spring, and pushing the low limits of the datasheet as far as temp was concerned. Interlux advised me that I could go another 10 degrees colder but I would need to add something like 24 hours to the recoat time. I'm sure it depends on the paint.

Our boat is the-one-and-only Cal 34 in Seward, Alaska. We are thinking ablative because the 24-hr sunlight in the summertime causes remarkable growth of slime and some sort of seaweed on the bottom of our boat (no barnacles, since the water is too cold), unless one can recommend something else. We cleaned the bottom twice last year (a cold, cold SCUBA dive) and need to double our efforts this year. Nothing grows in the winter. We are thinking two coats and a third along the waterline, as mentioned in our sailboat maintenance book. Its expensive, but we aren't shy to take our boat out into the gulf and over towards Prince William Sound. The annual glacial melt causes lots of unpleasantries, such as logs, to be floating around most of the fjords. Took a nice chunk out of our paint along the keel, which I think was only a single coat. I'll take a look into the Interlux 202. We plan to get a respirator regardless. I'm just hoping we can time our haul out during that short period where the weather warms up and its not raining! Thanks for the info. Happy sailing! --- In Ca… [at] yahoogroups.com, "Husar, Charlie [USA]" <husar_charlie@...> wrote: > > Hi, ??? Don't know your name or the flavor of your boat or your location.

Thanks. My significant other has been looking around and most manufacturers never seem to list temperatures on their websites. I guess I could also inquire into some local knowledge, but I'm a bit leary because everyone has an opinion about things...especially sailors! --- In Ca… [at] yahoogroups.com, "Bob Ellison" <bob_sharon@...> wrote: > > I would take that one step further and recommend that you contact the manufacturer.

when we did our haulouts, we were able to actually telephone the companies and speak to the people who were able to give us precise info. there is a phone # somewhere in the brochures. If you are calling France, you may need to correlate the hours of the company, but the 800 #s called us back each time. (they want you to succeed)we watched a huge (formosa 50+/-)do-it-yerself job go with the nonsand, too much time, cold air, or moisture in between, or incompatible products, looked great but 24 hours later it was on the ground. We couldn't bring ourselves to ask, but the boatyard did put everybody there on a no exterior-work program for a day. They did peel off the rest of what was left and I think they sanded what was left to reprep. I like 2000E barrier coat (do grey or white then switch for second layer to be sure it's covered)followed by Trinidad (2 diff companies, but ours still look good) There will always be that fingernail biting interlude till you're done (I couldn't watch our mast being restepped once). If you are fearful, have the yard do it, learn for next time. Could save you a bundle.
