Painting Questions

[Wcsweb]

Hello Everyone,

Great fourm here I have read alot but didn't find this question and was hoping someone could chim in.

I'm going to be painting a 20ft 79 cc Proline. I was woundering if I could use one kind of paint to do the entire boat? I was looking into using Interlux Brightside and wanted to use a Airless Spay Gun to apply it.

Please direct me in the right direction for this project.

The boat will not be sitting in the water all the time.

Thank You in advance...

Re: Painting Questions

First off welcome to the zoo !!

Basically you should limit the immersion of topside paint to 72 hours - TOPS -at any one time. If you want to leave it in longer then either do an antifouling job on the bottom or leave it alone. Paint from the waterline up.
Now, using an airless sprayer might be handy but I'll throw a couple of downside items at ya'. One - you'll not get the proper atomization from that machine even using the smallest FFT tip. Second - you're gonna' have a lot of paint in your hose that will be unusable. And at $30.00 or so a quart it will start getting really expensive. Gotta' remember that marine paint and house paint are two different creatures. If nothing else then by viscosity.
Buy a cheap $100.00 gravity gun. Use a .17 tip and shoot it at 35 to 45 pounds. You'll need three coats minimum for any decent coverage.

Re: Painting Questions

The boat will be stored on a trailer. Thank you for your response.

Can I use topside paint to paint the entire boat?

Re: Painting Questions

Yes you can. Just don't leave the boat in the water over three days. And that is after two full weeks of curing time. Don't confuse dry to cured - big difference. However you can splash it after 72 hours - read the can.

Re: Painting Questions

Thank you for your response.

When painting the inside of the boat do you need to add any kind of anti skid to the paint? Or is it ok just to paint it as you would do with the outside of the hull?

Also about home much paint do you think I would use spraying it on for a 20ft cc?

Re: Painting Questions

Adding nonskid to the interior deck is a good idea. Pretty much all of the marine paint manufacturers have their own brand. It really isn't much more than refined play sand. So if you want to save a buck or two just use that - but it must be completely dry !!!!

As far as the amount of paint to use it all depends if you're going to do all of it or just the hull. Also depends on the color you are trying to cover and the color you want to apply. Let us know your exact plans and we'll go from there.

Re: Painting Questions

you will prob use 4 or 5 quarts. I did 2 coats of my 16 ft runabout with 1 quart or top side paint. But that wa sjust below the waterline.

Re: Painting Questions

Again thanks for the great info.

The boat it white and the bottom of the boat is faded blue. I wanna paint the entire boat white.

Re: Painting Questions

Another question for you - is the 'faded blue' old antifouling paint or a topside enamel? Makes a world of difference in your application.

This is the only thing I have read that I disagree with so far. Good antiskid is not made from refined sand. It is made of a poly bead material that is compatible with the paint so that it will bond with the paint and the painted surface.
I have heard of using sand as antiskid. It may work fine, I have never used it.
I have used Interlux Polymeric anti-skid and it works great.

drewpster - I will agree with you 100% on that point. At $35.00 a quart - or thereabouts - I was simply trying to save him a buck or two. The playsand does have its disadvantages to be sure - but it's cheap !!!

Re: Painting Questions

The biggest thing about painting is preperation of the surface. You have to make sure all loose paint is off. That is really hard to do. I would suggest using a pressure washer to blast off all of the old paint. even the paint that looks like it is not comming off will chip off with use and mess up the new paint.

Re: Painting Questions

I think the old paint on the very bottom is the antifungle paint. How can I be for sure?

Re: Painting Questions

You can usually tell just by looking at it. Or take a wet rag and wipe it pretty good. If it comes off then it's probably antifouling. Also smell it - sounds weird I know but bottom paint has its own peculiar odor.
Now another situation arises for you. If indeed you have antifouling applied the bottom of your boat it should have been roughed up pretty bad with 80# paper for adhesion. So ------ you can either reapply the bottom paint or spend tons of time on your back sanding and buffing it all back smooth again.
It is a no brainer for me - slap some more bottom paint on.
Yea I know, if it ain't one thing it's another.

Re: Painting Questions

your going to have to sand either way, but first water blast it. And don't waste money by painting an unprepared surface, the new paint will just come off in a month.

Re: Painting Questions

Is there a cheap good bottom paint? Or can I use topside paint?
