Petit Vivid - Number of Coats ?

[Nemos]

We are about to do our bottom with Petit Vivid? With this paint, is there any reason to do more than one coat?

Thanks.

I do three coats the first coat is red and the next two are white. It last about two years an I have the bottom cleaned every 6 to 8 weeks boat is in the water all year long.

Thanks.

Why the first coat red?

We were told not to have it cleaned because it is semi-ablative? But you found tht O.K.?

Thanks again?

First coat is red so I can see it if it is comong off to fast. I am using white for the outer coats. I am at 2 years and 3 months with no issues I can see the red on the leading edges. Water line paint is no longer effective. I am holding off to haul until oct or nov. I love the white bottom with a blue hull it get clened about everyt 6 weeks boat is in the water year round

The first red coat (when showing) is a "telltale", that the (2) overcoats have worn off.

Yes; to achieve a build-up of 2 mils, using 3 THIN coats.

Vivid is applied in thin coats, using a 3/16” or less nap roller. Do not apply this paint in thick films or in more than four coats as poor adhesion may result.
METHOD: Brush, roller, airless or conventional spray.
When applying by roller use a short nap (3/16 inch maximum) roller cover
NUMBER OF COATS: 2 or 3
DRY FILM THICKNESS PER COAT: 2 mils (3.1wet mils)

After the first red coat (which is also some sort of epoxy hardcoat), we then do the following 2 coats of antifoul one black and one blue - (this showed areas of wear - leading edge and waterline) - which we covered with an extra two layers of anti foul last time, and they still are showing the red first again! But it's 3 years since we lifted.

WE also scrub every couple of months. It's the scrubbing that wears the antifoul down. You have to scrub slime and few barnacles off bottom. Even the best antifoul paints don't keep your bottom free of foul, I'm afraid!
