Coat the styrofoam with gesso or Zinsser primer. They're acrylic and will add a 'wall' between the foam and spray paint. Painting it with latex paint would also be good. Whatever you use, be sure it's an exterior product. It should work fine. Hope that helps. Linda

I love head planters, too. I hope you will post a photo when you finish.

Where do you get the styro heads?? Haven't seen those in years.

I totally forgot how spray paint can melt styrofoam! If you don't have leftover latex paint, you can get those "patio" acrylic paints at craft stores. They are made for outdoors. I sure hope you are able to post a picture of your planter. There are so many cool plants you can plant for "hair." One of my favorites is ornamental grass.

I used one of those heads the other day when I made a garden man, from my Dad's old overalls and shirt that I had been keeping. I used the flat fronted head, and then put a straw hat over the face. Like sleeping. Did not want to try painting a face since it is a MAN!
Speaking of stryofoam and spray paint, I learned something last week (on line of course). I immediately tried it--take one of the small stryo coolers, and spray it GENTLY with the gray. I did it with straight lines around the cooler and then sprayed in spots. Trial and errer. It is light weight, but looks like concrete!!!!

Thanks for the ideas! I will try to learn how to post pics cuz I'm anxious to do the head pot thing. I already have a spiral grass plant to put in it.We have a resale shop in Madison WI called Savers that sells the wig heads for $2.99. I'll get another and try soon!

Just curious, but couldn't you take the wig head and make a mold with it so you could pour your own concrete ones? Not that I've ever tried it, but it sounds good in theory LOL
That way you could have the "real McCoy" at a fraction of the price.

Wish I had thought of a planter when I painted mine. I ended up throwing it away when I moved. I painted mine with regualr craft paint and then put on a coat of glossy clearcoat. I never used it outside, but if I had thought of the planter idea I would have.
