Spraying antifoul

[Binman]

Is this a good idea.

 

[PaulRainbow]

Most of the work is in the prep, applying it doesn't take long. I think it would be more effort than it was worth, would take longer to mask up, hang sheeting to contain the over spray and don the protective clobber than it takes to roll a coat on. A radiator roller makes short work off it.

I think that you will find most antifouling that is used on leisure craft is intended for application by brush or, preferably, by roller.

I did think on this but just prepping the spray equipment and preventing overspray would be a lot more work than the time to roller the stuff.

I thought the principle benefit is a smooth finish (on a suitably prepared substrate!) for racing craft.

Unless the OP means the spray cans sold for use on saildrive legs, etc

I imagine it will be difficult to get the required film thickness with a spray gun.

I would not have thought it a particularly good idea but it can be sprayed.

The manufacturers data sheet for your chosen product will give all the technical information. Ie tip sizes, pressure for airless spraying or air pressure for air mix spraying, wet film thickness etc.

You will be very unpopular if spray mist drifts onto other peoples boats or cars if you do this out in the open.

In which case, airless is the better choice of spray equipment, if you do decide to go down that road.

And remember you will be spraying a toxic substance so see also the manufacturers safety data sheet for any special precautions necessary.

I have seen a boat that had sprayed Coppercoat, presumably airless spray, done in Holland. It was done very badly with terrible orange peel. I guess this was quite a difficult job but my roller applied looks a lot better.

Obviously not a very good job, Vyv. The sprayed Coppercoat jobs I've seen are certainly smoother than rollered ones. But while it may be worth all the associated faff for a product as expensive and durable as Coppercoat, I'm inclined to agree with PaulRainbow that it wouldn't be for a conventional antifoul.

Strangely enough I've just had an email exchange with Seajet (the paint manufacturer...) on the subject of spraying their 012 primer and 038 afoul, and whilst they do give info for spraying they do say that a mohair roller gives the best results. I've asked about that, and the answer is that they don't seem to expect people to have a decent spray setup.

So, because I'm lucky enough to have good tools, and perhaps more crucially, the boat at home, I'll be spraying it.

And the appropriate enclosed spraying facility with fume / mist extraction to ensureyou do not also spray your neighbours with toxic antifouling I hope


So easy with a roller and no equipment to clean up afterwards.

Nearest neighbour is a hundred yards away, so outdoor spraying - with a really good mask. Once I've set up the waterline masking, I'll time the job through to clean-up. I bet it's quicker, but I won't be doing it until March/April, so you'll all have to wait for the result - and possible humble pie.

Sadly it appears not to be the case

I'm not entirely sure sure what you mean by that?
