Of course, the other thing you can do is make up a mix of PVA glue and water, (3:1 ratio) and apply this to the polystyrene. It will seal it, and it is then safe to prime it with an aerosol.
Just make sure you cover it all.

| Post subject: | Paint on Polystyrene |
Hey everyone! I havnt been on One-Ring all summer but I am getting back now, wich is good as I could use some advice. I'm building a game board wich will be a moria board or some other dwarven hold and will include Polystyrene cave walls. what I need to know is what type of paint to use on the polystyrene as I dont want to put hours into modelling it just to have it shrivel up when I apply paint. all answers are appreciated! |

Acrylic paint, applied with a brush or roller is fine for polystyrene. Don't use a spray can because the propellant is a solvent, and some of the thinners used in enamel paints will dissolve plastic too. I use cheapo acrylic paints straight onto styrofoam and it works just fine. |

I see that you are in Alberta, as am I (Red Deer), so my advice will be relevant as far as brands etc. For all my terrain projects, I go to Home Depot and do one of two things: 1. buy a small tin of Painter's Touch by Rustoleum, in Flat Black. Makes a perfect undercoat for whatever I am doing. I have had the same small tin for years. 2. go to Home Depot late on a Friday or early on a Saturday. They will have an orange flat cart with all the mis-tints from the week. You can usually find various greys or browns, and they are around $15 for a whole gallon of the stuff. Small tins too, usually around $8. Watch you get a latex interior paint, and not like a deck stain. This is always a winning venture. Of course, you can take any colour down to a real paint shop like a Benjamin Moore and get them to custom tint a whole paint can. Any colour you want, they can tint it. Enjoy! |

Just make sure you cover it all. You can add a few drops of paint (green or brown) to that mix so that the PVA coat stands out and you dont miss any spots. |
