I stumbled on a few articles last night.

http://www.simplicityboats.com/latexcarnel.html

"Boatbuilders are traditionalists and it has been a hard sell to get them to accept plywood, stitch-and-glue construction, epoxy adhesives, and other similar innovations. Don?t let tradition keep you from benefitting from the ease of application and outstanding performance of 100% acrylic latex paints."


http://www.epoxyproducts.com/hindsight4u.html

"We have discovered how great exterior latex paint is on boat surfaces above the waterline and on epoxy surfaces. A top quality semi-gloss, exterior house latex (like that used for trim or shutters at $30 per gallon) is easier to apply, easier to clean up, keeps it shine much longer and is more fade resistant than any marine enamel I have ever used. It is also less brittle and less subject to cracking. Being slightly porous, it resists blistering much more than enamels. It all makes sense. Paint companies have performed a lot more R&D in the competitive, huge, house paint market than in the much smaller marine paint niche. Another plus - with custom blending, you can get any color you want."

I'm not trying to start a flame war here. I'm also probably not willing to be the first in the flock to try it. I do find it interesting when people are willing to experiment and share their results. The first article is particularly interesting to me. Maybe I'll paint some test pieces and leave them outside to see what happens.

Is there a good argument against using this topside other than latex doesn't belong on a boat? My house is subject to more environmental abuse than my boat.

Hello i386,

I have been considering latex also, for the hullsides.

Will be watching your thread to hear the news.



Enjoy

Re: Latex paint for topside

I read everything I could find when researching paints for boats (I had to refurbish a jetski hull). I ended up using an industrial enamel. I believe the "boat paints" are 99% similar to something off the shelf at a hardware store (comparing acrylic enamels to acrylic enamels, polyurethanes to polyurethanes, etc). But back to the original question......

I've also read of people using latex on boats, just that it could take some time to "cure." It's water evaporating out of latex, not solvents, so it's obvious they're different in that respect. Of course, film thickness has an influence on that also.

Only argument I could make against using it is that I doubt you can sand latex to get a mirror shine like the solvent-based paints. Whatever gloss you'd get from spraying it/rolling it is what you're going to have to be happy with. Price is approximately the same, latex is a lot easier to clean up.

pressure washed, and painted 2 coats, with a 3 inch roller, 2 inch brush in hard areas, then rolled over brushed area. this is my $150 boat came with a 1966 50 merc. i have done nothing to it but let it cure in the sun. it has had several rain storms, and does not appear to scratch, since i've been working inside.

I've seen this info before, but have never needed to try it. I don't see why it wouldn't work though.

Your house does not flex.......;) which will break up any latex...but enjoy and keep it very thin.

Re: Latex paint for topside

The boat I'm currently working on came with acrylic on the topside. It was ok but was wearing and I guess oxidizing. Whenever you ran your hand over ii, the hand was white.

What could you seal it with?

Hey TD, so you did the white topsides in latex acrylic? Need details on the paint, where bought and how much? I'm trying to get twin 57 Evinrude Big Twins on the Texas Maid right now, then I move on to topside paint.

Re: Latex paint for topside

So that works for the top side, what about below the water line, paint with anti-fouling is expensive. It would be nice to be able to match my boats original colors above and below...

Do I have to use Marine paint below the water line?

Re: Latex paint for topside

the hull of this one has one coat of Rustoleum oil base flat paint, and one coat of rustoleum oil base gloss. i've been using it for several years, no problem, and if it does get dock rash, it's easy to touch up.

Re: Latex paint for topside

TD, looks good! did you have to thin out the paint and if so by how much. Also do you think this will work on a aluminum boat if I rough the old paint and paint over?

Re: Latex paint for topside

Hey TD,

So you used an oil base paint for Below the water line?!? I was thinking on using interlux (expensive) stuff. How has it been with it on for several years? How does it compare to marine below water line paints? I'm not painting anytime soon but wouldn't mind the info to your experience. Did you prime?

It would be much cheaper to go with a walmart paint!!!
Thanks!!
