Can you apply antifoul to a wet hull?

[anubis]

Hi,
Drying out this week to check the bottom....does the hull need to be totally dry before you apply antifoul?
Thanks

It helps ... otherwise it just falls off when the water returns!

It used to be common practice for skint sailors to put on a coat of antifoul between tides. These days hauling out is quick and convienient, and we all seem to be a lot richer. I have done it lots, with no problems.

it does not take long for a hull to dry on the surface in the right conditions,if its dry on the surface then it can receive anti foul,what you really need to check is the drying time of the antifoul-some brands take longer than others.
hope this is of some help.

I have on occasions done an antifoul job from water back to water in 2 hours. So the hull was not very dry. Seems like no noticeable problem. olewill.

Whats this 'used to be...'? Look at any hard round Chi Harbour this time of year and there will be 'skint sailors' applying their antifoul..... self included! /forums/images/graemlins/smile.gif

The original question about 'wet hull' - there must be no trace of surface moisture. If there is, the paint just floats off again on the rising tide. Ideal conditions are a sunny day with a good breeze - the a/f will have dried within half an hour. The problems come if there is water trapped anywhere and trickling down - like from the keel / hull join.

I've antifouled and done my boottopping quite a few times between tides, one side a tide. I would still be doing it that way, if there were any decent tides in the meddy! Considerably cheaper than a boat lift for 57' and 48 tons which are not easy to find.

One word of caution. I have been anti fouling my boat today - she has been laid-up on the hard since October when I bought her. She has previously had self eroding anti-foul and after jet washing, scraping and sanding I thought that I had got the undersides just right for a coat of International Uno.

When I started to apply the stuff the previous coating was cracking and lifting as I applied it - after consulting an old sage in the yard I learned that I needed to prime over the old stuff before coating with new.

I shot off to the swindlery and bought some primer which went on a treat and looks to provide a good base for the Uno.

I dont know how folk manage to do all that between tides and still get a coating that stops the little barnacle blighters from eating your boat.

Incidentally, I mixed a good size pot of vindaloo curry powder into the Uno as advised by various peeps.

If the previous coat is cracking and falling off in several areas and not just a small isolated area. The antifoul has reached the end of its ability to be overcoated with any product. The entire bottom needs to be scraped of all previous antfoul coats prior to priming. This should not be done between tides and really would require a lift out to be done correctly.

If chilli and curry worked, do you not think the manufacturers would be using it. Has anyone tried putting chilli on one side of the boat and then leaving the other side as per the tin and checked the performance at the end of the season?

Re hauling large boats for DIY work. Adra seem one of the best in the W. Med and cheapest for hauling a large yacht to work on DIY. I can get the name and phone number of the manager who looks after it, if you like - he speaks English.

I think that maybe curry powder is one of several "agents" that barnacles find unattractive - manufacturers arent going to do anything for the chemical mystique surrounding their hugely expensive technically formulated products if they advertise it as "With Added Curry Powder."

I'm just going off anicdotal evidence - lot's of people say it worked for them so I'm giving it a try.
