Painting the hull
« on: July 06, 2008, 03:15:07 PM »

I'm about to paint the hull of my Vliestroom and i have 3 colours to spray on, Red on the bottom for the waterline, black for the hull and white along the top. My question is, which colour do I do first, and do I spray it all one colour, then the next colour over the top of that, and so on. If you know what i mean.  :-\

I would say to apply the lighter color first because a dark color will cover over a lighter,
 to where a lighter color will require many coats to cover the dark.

I would go with the white first, then the black and finish off the bottom with the red in this case to make it easier to mask off..

I made some bad experience with mixing black on white color, even twice. Tried with 2 different paint types and both did the same.

So never paint white on black or black on white.....those colores simply can get along together, don't ask me why  :(

Hi, sorry to see the bad blistering / cracking on the paint job.

I know that this is after the fact but did you key the hull in first?
I use 1000 wet n dry then spray with a red oxide colour which is the closest I could find to antifoul. then flat that back before applying any more paints (any colour)

R,
I tried key in the hull first and also leave it. Makes no difference. Had to remove ALL the paint 3 times before I had a nice paint job. Same second when the black paint hit the white, it starts to blister. Even after 1 week break between the two paint jobs. The blistering happens ONLY wtih those two colors, didn't happen between the red and black color.
But at last I had a sucessfull paint job, I just had to make sure that no mixing between the two colors occoured.

Ok were the black and the white from the same manufacterer? it sounds to me that the white was  an enamel and the black was either cellulose or acrylic as this is the only way that a reaction would take place.

Yes both colors from same manufactor. And after the first attempt, I tried to switch to a completly different manufactor for both paints and again the same results. Weird isn't it.

Have been painting boats for centuries and have never seen anything like it. But also first time I combine these two colors. All other combinations works without problems. Black/Red, White/Green, Black/Green, White/Red  all okay.
