Thread: Waterproofing Painted Foam?

Tweet

I did a few Skull heads for new GB's, And I painted them entirely with Silver,Black,and White Acrylic Paints from a craft store. What can I seal this with to make it waterproof? I don't want the paint running off during rain and ruining the prop and the grass around it! I also want something relatively cheap! Any Suggestions?

if all of the foam is covered then just a little clear coat did the trick for me.

you can get the poly spray at walmart. that should work well enough.

If you used acrylic paints, then technically it is waterproof (acrylics are a polymer that dries to a plastic coating).

If you want to protect your paintjob, then you'll need some sort of clear sealant like the polyurethane the others mentioned. If the foam is completely covered, then you could use the spray stuff (aerosol spray will melt foam-but the paint surface protects it from melting) if you've got some gaps in the paint, then you could get the stuff in a can and brush it on. They come in shiny and matte (flat or dull) finish.

I use Acrylics on all my foam projects. Last year one of them got wet, and it made the paint run off the foam, and leave it half painted with huge streaks, and it ruined the floor around where it was (Got it off with some elbow grease )
