Painting Foam Insulation Board?

Some of the pink foam insulation has a thin film laminated to it. I peel that off before painting. The foam is porous and will soak up some paint. If the film is on there. you're just coating the surface.

I just painted 2" foam and I found craft paint from Michaels and the like works great. It is also cheap. 

Carl...

I couple thoughts...did you remove the thin film on the foam board...some come with a very thin film that should be removed...this film is a tog hone for paint o

to adhere to...also, I find a light roughing of the surface helps...I add some portal cement to the paint/water base coloring...then apply the "paint" and proceed with washes and scenery

Fer cryin out loud. I didn't realize it had a film on it. Sure nuff, it's there. 

Thanks for the tip!  How embarrassing......

Carl, you are not alone! Been there, read the movie!

Also seems to absorb sound better when the film is removed. I used mixed leftover latex paint from Home Depot to paint the foam[after film removed].

Dewey, et al; I "discovered" that at Home Depot's paint dept., they have small jars of paint - 7.25 oz each - that they'll mix to any color for "test" purposes. Can't recall the exact price, but in the neighborhood of $2.50. One jar is just about perfect for a 4x8 board. I bought several.
