Need primer?

Post by Otter »

I am getting ready to use WR-LPU on my boat...any need to use a primer? I already bought the system 3 primer. When I read the instructions for the top coat paint, they seemed to indicated it can be applied directly to the epoxy.

I used the primer wh I used Wr-lpu. I think it evens out the tone and gives better coverage with thinner coats.

Chris-
I didn't use the primer on mine and the epoxy base coat was fine. I was using the Mercer green (and Clear Gloss on the brightwork), but I suppose over lighter colors, the primer coat first might work better. Can't hurt to use it since you have already bought it.

Billy is correct. Darker colors will cover better. Whites and yellows not so good. Remember to keep humidity high, thin the paint to prevent fast evaporation and allow better flow and leveling, and apply thin coats. Avoid trying to fix blotches and cover too quickly. This stuff will cling when applied too thick and suddenly run right to the floor. Flood your floor with water to add to humidity and keep dust down.

I used primer under my wr-lpu. I was doing red which has a hard time covering, so the primer helped.

I did the bottom in red without primer. It took five coats to hide everything.

+1 on primer under red. Something about red pigments. Epoxy must be a suitable surface for the top coat, since my clear gloss stuck to it.

Like Roberta said, raise the humidity in the shop any way you can. Water or the floor and I used a room humidifier that we had to help you breathe when you are sick. It will help the paint flow and keep a wet edge for blending.

Unless you are spraying, expect a bit of orange peel and brush marks. If you want a super smooth, glossy finish you will need to wet sand and buff it out.

I used VC Performance on the bottom of the Tahoe without primer. It only comes in white.

I used Pettit on the Bartender. They said to prime. They have two primers, white for light colors and a grey for dark colors. For darker colors they said mix some of your top coat with the primer.

That is interesting Bill, I would think that suggestion is so any scratches won't show quite so much. Since most bottom paints are designed to wear away (ablative), I thought the point at which you can see the primer is an indicator that you need to re-do your paint?

The VC is an epoxy paint with UV inhibitor, It also has a lot of Teflon in it. It is tough!
