Painting Preperation

[Thuffjr]

Hello All
Im planning on repainting my boat, and since it is not kept in the water I am not using anti fouling paint on the bottom. I know i need to apply a dewaxer of some sort. My question is do I have to paint right after dewaxing, or can I dewax one day and prime another? Also di I need to strip old botom paint befor applying Interlux epoxy primekote? Thank you for any help and im sure I will be back with more questions befor im done.

Go to their website and follow the directions, also you need to know what's on there now before you paint over it.

Not knowing if its aluminum boat - but if it is you need a special aluminum etching primer for bare spots.

If the boat is fiberglass consider buffing before you decide to paint - wetsand with 1000 grit and then buff out.

If painting - then wetsand with 400 gritt then follow up with primer only on bare spots only - no use wasting money priming the entire boat.

There are alot of paints that people use on this site - so go ask questions from folks with finished products - personally I sprayed on a paint similar to rustoleum and used my hlvp sprayer.

Epoxy Prime-kote comes in two parts. The two parts must be mixed along with 2333n solvent prior to use. In the can prime-kote is about like marshmallow cream until the solvent is added. It will then loosen to a paint-like consistency. Yes, it must be thinned.

It also has strong solvents in it. Interlux does not recommend coating over unknown paints. the solvents in the primer and the paint can break down the underlying paint causing it to fail. Unless you know what paint was used before and verify that it is compatible with prime-kote, you run the risk of problems down the road. Personally i would remove it.

I have had the best luck using chemical removers rather than sanding it off. the trick with paint removers is to follow the directions very closely. Most gel removers recommend dabbing the remover on rather than brushing. There is a reason for this, so follow the rules. Most also recommend keeping the remover wet. The paint will not come off if the remover is allowed to flash in the breeze. The best I have found for fiberglass is Citristrip or Kleen Strip Aircraft remover. They both work very well. I have also heard that Marine strip works great, but you have to be strict about the directions and do it the way they say.
