Krylon Rattle can H20 paints work great on foam.
Someone may have made a post about this water base paint
One problem working with foam has been getting the right paint. Most spray can paints will ruin foam , just dissolve the foam. Leaving a melted mess.
H2O paint is water base paint in a spray can. Over spray clean up with soap and water up to 20 minutes after you spray.
No waiting for a second, third coat of paint.
15 minutes drying time.
Tried it on the tunnel portal and some buildings all made with unpainted blue foam.
Worked great.
Now I have to see if I can use acrylic and acrylic latex paints to fini***hem.
At present I saw only eight different colors on the shelf.
The only place I could find H2O paint was at Wal-Mart.
I’m using a light tan color as a base color in the pictures.
