Can you paint an exterior acrylic oil based paint over interlux brightside

Hi guys I only have enough interlux brightside to do one coat of one of my hulls. I was thinking of painting over the interlux brightside with an oil based acrylic enamel exterior house paint that I can buy locally and color match with the rest of the boat. Do you guys see any problems with this? Would there be any adhesion problems?

Thanks for all the help guys!!

 

Sand well!
The house paint won't do well submerged.
The house paint will fade faster than the Interlux.
House paint is less scratch resistant.
House paint has a lower visual quality.
Interlux feels better than house paint.

 

Rustoliem would be better than acrylic and is available for tinting.

 

Forget the acrylic. Here is a chlorine pool paint recommendation. Epoxies are said to last 2-3 times longer.

Keep in mind, pool paint does NOT typically see temp extremes. And even UV is tempered. So a boat is a harsher environment, sans chlorine.

Stick with polyurethane Ron. One or two part..over epoxy...even Sherwin Williams sells polyurethanes..

 

Pool paint is usually flat. It will not match the gloss finish of Interlux. I would use the Interlux on the outside of both hulls and paint the inside with a cheaper paint.

 

don't get lost in the point please

I used acrylic pool paint as a basis for establishing lifetime of 3 years for Ron because I have no boat lifetimes to compare..and the point is that acrylic sucks..

Acrylic enamel is not the way to go..

 

I'm limited by what I can buy in mexico and I can't find any polyurethane locally. What house paint would you recommend for a marine environment then? Should I go with oil or water based acrylic latex or enamel? I'll do the last coat of the hulls with the interlux brightside.

 

Would there be any adhesion problems? YES
Above the water line I have used Rust-Oleum Marine Coatings 1 qt. Gloss Oil-Base Gloss White Topside Paint. $20 at big box stores.

For Interlux produce I would recommend Interlux 333 or Interlux's Brush-Ease 433 is a slow drying solvent designed to ease brushing, rolling and to improve flow. Interlux Brushing Liquid 333 is a slow drying solvent formulated to ease brushing and facilitate the flow of specified paint coatings and 216 for spraying. You will see a difference.
Read the directions and follow the directions.

Don't breathe the foul air.

 

Don't use any water based paint below waterline.
Don't use water based paint under any oil.

Do use rustoliem.

 

Hi guys many thanks to all the amazing people and all the advice I really appreciate it!!

So I was able to find someone who can order me amershield polyurethane polyester acrylic paint in mexico (https://specialtycoatingsinc.com/products/amershield-voc-polyester-acrylic-polyurethane). The label says its for metal and concrete but the guy said it would work perfectly for a boat. I shouldn't have any issues using tbis

 

You must use an epoxy primer first.

 

Thanks fallguy! Do I need to put a epoxy paint primer if I'm painting it over epoxy?

 

Yes, it will help you make the boat look better.

 

Thank you fallguy you are absolutely awesome!!! I couldn't find any epoxy primers locally but I was able to find a 2 in 1 epoxy paint primer combination where you have to mix the paint and primer together and apply the mix. I plan to paint one coat of the epoxy paint primer mix and then how many coats of the polyurethane polyester acrylic should I paint? Thanks to everyone for all the great advice I really appreciate it!!!

 

Normally, you paint a mist coat and do any additional fairing and longboard work. Sand to 180 grit. Then 3 coats of epoxy primer. Then sand to 220 grit. Then two coats of polyurethane, sand 220 or 320 to finish. Then a final coat of perfect.
