Default What type of paint is best on foam?

What is the best type of paint to use on foam? I have heard that Krylon H2O is the best because it is latex and flexible with the foam but I have also heard people using stronger acrylics too. Any info is appreciated.

Thank you.

Best is a matter of opinion, some will really like a certain paint and others will hate it.

What I can tell you is what I have been using for 5 years on depron and Styrofoam, and that is Testors spray enamel, it does not seem to flake or chip off, no matter how hard I have hit the ground or something else. Even though it says to clean spray nozzle with paint thinner, it has not affected my foam.

Another one I have used but not much is, Krylon Short Cuts, it says, usable on craft foam, but it does list acetone in it, I use several thin coats, and it seems alright.

I have not tried latex, but I am going to thin down some gloss and put it in my airbrush, and see what happens.

+2 on the Testors make sure its the one safe for Styrofoam it will say so on the can at the top, the krylon short cuts works great too, But in thin coats like wildflier says The Krylon H2O latex paints are very very heavy, and does not stick very well IMHO.

H2O works good on foam, shoot light coats at a time and fog it on, drys fast.

Thanks everyone, I am pretty sure my LHS carries the Testors enamel line might try that first.

I'm a big fan of the cheapie acylic paints from the hobby section of WalMart. Dozens of colors and easy to custom mix to whatever you want. I thin it with rubbing alcohol about 50/50. If it is too thick, it will spray blobs from my airbrush.

Not bad with a good brush either when thinned.

Wipe with alcohol and lightly sand the surface with 400 or 600 grit sandpaper first for best adhesion with any paint.

All I've ever used on foamies and very happy with it. Lots of colors to choose from, readily available, and very affordable.

Default Paints

Being new to foam planes I searched around and a pretty common plan was to use Polycrylic spray as a primer and then most paints will be OK. I don't totally believe that so I have been using Testors Pactra paints but only thinned with their thinner for my air brush. This is just my opinion but maybe it will help.

You folks do know to turn your spray bombs upside down after painting and spray till no paint comes out to clean the nozzle right, otherwise they get stopped up (everyone probably knows that already)?

Whatever paint you decide to use, keep it in THIN coats. Paint can add a LOT of weight quickly. If your airplane has a long fuselage and/or large tail, paint will move your cg rearward quite a bit quickly.

I LOVE Vallejo air.
Ready to use in an airbrush and is fairly durable for acrylic paint. Also comes in luftwaffe colors.

Pretty much anything, dependent on the foam. For your Trojan, the Testors I would say is #1. It's a lot like the Stryker foam, nothing wants to stick 100% to it.

For acrylics, I've always used FASKOLOR from Parma. Can be brushed or sprayed.
http://www.parmapse.com/fas1.html

I've heard,read,viewed great success with WOW Products coating used first as a base.
Gives a much better base for your paint to stick to and adds strength to the foam, and unlike fiberglass, is flexible.

Household Emulsion Silk paints .... water washable ... weather resistant when dry.

Available in any colour or shade you want mixed while you wait. Cheap and plentiful ready for touch-ups / repairs etc.

For warbirds - the flat version is nothing short of amazing. And coverage is very good with little weight build up.

Here's my Me109 before in 'toy-like' finish :



Here after a repair and repaint job with common emulsion ....





and careful use of permament marker pen ...

Greetings,

Happened to notice this thread and wanted to add my $.02 Just finished my first Depron foamie. Painted it up using Createx acrylic paint with my airbrush. The paint sprayed great unthinned about 18 psi from my airbrush but adhesion was very poor. I did everything I could including running a rag with alcohol over the surface before painting. It was a very frustrating experience. I had heard good things about Auto color and happened to notice thay my hobby shop had some in stock. I picked up a bottle of white just to try it and some test shots were very promising. Sprayed great right from the bottle and it seemed to fill the pores of the depron more than the Createx. Most importantly, it did very well on the adhesion test. After waiting for the paint to dry a bit, no lifting with blue or green painters tape. Createx might be fine over a base of Auto color but since Auto color, like Createx, has a wide range of colors, why bother with the Createx. BTW, I did the createx in very light coats helping the paint dry between coast with a hair dryer. The Createx dries fast but no stick.

I use craft paint from Walmart and put on with a brush.
It will do a better job of adhering if you tape the surface and then remove the tape leaving the surface grainy.
If i am bending a wing out of foam i tape one side anyway.

Krylon Fusion for plastics is great!. It is NOT a water based paint. I used in on an EPP kit and I could do a reasonable job with one coat.

Thank you.
My advice is to use acrylic craft paint. You can buy it from a craft store like "Michaels". When you buy it, get the big plastic bottles of white, black and silver when it's on sale it costs less than 2 dollars. All the colors of the rainbow can be created by mixing the other colors but you will always need black white and silver.

I agree with Barry. That's what I did for less than $1.30 a bottle. I just kept mixing until I got the perfect match to my corsair and T28. I put what I mixed in some old empty acrylic bottles now the perfect match sits in a bottle on the shelf ready if needed. Works great for me
