Colour of antifoul

[bobtooke]

Does colour of antifoul make any difference to its effectiveness?
I've been told that the most effective is black and the darker colours. The worst are the lighter colours.
I wanted to use an off white so as to blend with the gelcoat appearance but not if it's at the expense of effectiveness.
Can anyone offer advice or experience?
Thanks all.

Not that I know of.

I would avoid white of any kind as the scum line will get dirty and be noticeable. For this reason I use black.

Darker colours do seem to work better. They don't reflect the light that encourages the fuzzies.
white or pale gray show the dirt really quickly and start to look a bit scruffy.

Hmm point taken. Seems like black is the way to go then to avoid looking rough, aside from effectiveness.

Someone told me the lighter colours have less copper, as the copper darkens the 'paint'.
Not sure how true it is though.

I've been told the same.

I've been told the same.

So, I guess that means that the colour most likely to contain most copper is Black! ?

It's what my engineer told me. so I have black.. now that said. I still got bad growth last year.

We're having a good run with Coppercoat (contains a lot of powdered metallic copper) which seasons to the copper blue/green.

Had White once a few years back, looked great for a couple of weeks

Black every time now, don't know about effectiveness s but look a whole lot better for longer

Dark on light and light on dark. So you can always see the places that you missed when painting.

Since I have recently spent some time wet sanding it seems to me there is a lot of pigment in antifoul paint . The slightest touch with abrasive paper releases a rich colour. I guess this in part explains why it is so expensive.
Dark blue seems best in our area as the water is muddy and limescale is the main element of any fouling.

I always have black, because of the arguments above. The new antifoul should tolerate the existing one, if not removed. When is the right time to remove totally the old layers of antifoul and make a completely new set up? 10 years?
