Default GREAT PAINT for foam

Just tried out Krylon's "H20 Latex Spray Paint" Super Smooth White on a test piece of foam, very happy to report....
It is fabulous, coats with an excellent finish. NO bubbling of the foam.
I plan to paint the GWS floats with it.

Next test will be to coat/seal with Krylon's "Polyurethane Clear Wood Finish".

Will report later how it works.

Does it only come in spray cans or can you buy it in pint cans? It would be nice to be able to mix custom colors and use it in an airbrush.

Ratttle cans.

There are many options, including acrylic and latex paints you can use in an airbrush.

Finding a good foam safe paint in a rattle can is just cool.

Yep. If it's the colors you want, it's a lot easier than setting up and cleaning out an airbrush.

Default Krylon H2o paint on foam

I gave one float two coats of the Krylon H2o paint, then a good coat of MINWAX floor paste. (I decided not to use the Krylon Urethane as it gave a yellow color finish).

The float weight increased 1/2 ounce.

I saw ACE had Spray White Epoxy and was tempted to try it.
I think it might give the foam a harder "shell" finish so that dings and scratches would be prevented.

Anyone ever try spray epoxy on foam?

I use 30 minute epoxy to join the two halves and it works great but I don't know if the spray contains something that will "eat" the foam.

ACE only had the H20 paint in spray cans, but in a wide variety of colors.

I tried it on a scrap piece of foam once and it melted it, also being latex it seems to go on thick and add a lot of weight.

I'm sold on the 79˘ bottles of gloss acrylic at Wallyworld.

What is "Wallyworld", is that a nickname for WalMart?
Did you mean that you tried the spray epoxy and it ate the foam?
Please clarify, OK?
Thanks,

I got interrupted mid post, it should have been posted right after Twistmaster's first post way ahead of the epoxy post. LOL

Never tried the epoxy spray paint on foam but usually it's not the paint that's the problem, it's the carrier that eats the foam. My experience has been the higher the flash point of the carrier the more likely it'll eat foam.

And think about it, how can they have true epoxy paint in a rattlecan?

Default Wally's World defined....

Thanks for making it clear,

Around here, (Chicago land), we never refer to Wal Mart so affectionately.

Targe is used because the "Nort" siders acting so uppity.

Do you say Chi-cah-go or as true residents say, Chi-caw-go?

Default Eh !

Very true !!

My final question.
Where in wallyworld do you find the ,49 cent gloss acrylic.
What department?
Would liike to give it a try. Have you used it on the GWS floats?
How does it spread? Any brush streaks or does it "equalize" nice and smooth?
Thanks,
Don

It's in the craft department and I use it though an airbrush thinned 50/50 with rubbing alchohol. Thinned out it would probably spread real even with a brush if you used thin coats.

Actually what I found works best for me to paint large things is one of the testors co2 kits that attaches the bottle and atomizer directly to the can. I think I paid $15 for it at WAL*MART or Meijer.

Spent some time prepping the foam on my formosa and painted it with white gloss acrylic and it suprised me how nice it came out.


I only break out my compressor and airbrush for detail work.

Krylon Fusion?It works on styro?Never would have thunk it.I've been using Testors Enamel in rattle cans for a couple of years on my foamies and it works great.I would like to find something that'll give a harder protective shell without having to brush it on,I wonder,does the Fusion provide something like this?

Default Testor's Spray Enamel WORKS!!!

Guys,
Thank's to WaldoP's comment about using Testors Spray Enamel I checked my paint shelf and found I had a can of their #1245 Gloss White.
I did a test spray on a foam packing piece and was pleasantly surprised how well it worked. BEAUTIFUL!!

Previously, I did try the Epoxy Spray and it ate the foam.
Dave Platt recommends using a base coating over foam before applying their Klass-Kote epoxy spray.

After the Testors dry, I'll spray the test piece with epoxy spray to see if it will provide a hard shell and not penerate the Testors product.

Very impressed with the Testor product. Looks like I'm on the right track.

Yep,all my planes are done with Testors.The only drawback is you can't get to intricate with your schemes because when you mask a base color to do a second trim color,the tape removes the original first coat of paint from the foam.Here's pics my E-Starter and Beaver with Testors and 3M pinstripes.

Have you tried the blue painter's tape? The adhesive isn't as sticky so it doesn't take the paint off when you remove it. Only drawback is the stuff's expensive!

I use Testers paint also, I had the same problem with it lifting when tape was applied and then removed so I now sand with 400grt between coats and it solved some of the lifting issues but added to the build time. The Krylon sounds like a good choice if it's priced around the same as testers but double the can size, I hate those little cans for $5 that only last for one plane.
I 've also been told that if you hold the can to close to the foam no matter what paint you are using it will bubble the foam because of the propellents used in paint cans. I found that out the hard way......

There is a product at Michaels Craft stores called Envirotex, it will add a bit of weight but after it cures it is clear and drys hard as a rock. It has a very long cure time, about 48 hours but it is worth the wait. This is the stuff that they used to pour on wood bar or table tops. In that application it is about 1/8th inch thick. I painted it on a foam wing in a thin coat and it is tuff as nails. I plan on using it on a foamy in the future, however I have not got a round to it yet. When it drys it gives a SUPER high gloss finish. I was thinking it could be used in place of fiber glass.

I just used the Testors Semi-Gloss Lacquer Overcoat. Seems pretty good. Originally, I decided to use it on a plane that had semi-gloss green, but a bad choice of gloss brown camo. I wanted to dull the brown. It worked pretty well, but is a bit glossy for a semi gloss, may try flat next time. You can coat an entire park size plane with one half bottle, if sprayed properly, to add little weight. On on or two small areas, there was just the slightest bit of krinkle in the brown undercoat. Probably the fault of the brown paint, where it was too thick, from several different paintings on it. Either way, works fine, but I would keep it light, for both weight and reducing possibility of effects with enamel undercoats.

Another benefit is that I hope it makes the finish tougher. It was put over white Econokote, which was scuffed with a scotch pad, but still chips easily. I now use the Monokote flats, if I am painting over them. They weigh a bit more, and are more difficult to stretch than the gloss iron-ons, but they hold paint much better. Also saves weight on dark schemes, if you use something like a dark green flat Monokote, since less paint is required to cover it well.
