Foam core primer

Hi guys,

Can anyone point me at a spray primer that's safe to use on foam core?
I know you can seal the foam edges with pva then use anything, but is there something that won't melt the core straight out of the can?

Im in the UK so if anyone knows of anything a brand name would be good ta.

I don't know of anything, not sure if there is a spray product out there that won't melt it.

There are a couple of spray paints that are used for floral work that are safe to use on foam...it's the propellant that's the problem with the sprays.

Not a cheap option but you could use regular acrylic paint in an air-brush (powered by a compressor - don't use canned propellant though as it will have the same problem).

I think it makes more sense to seal with PVA then spray with normal paint to be honest!

Once I get to the painting stage of the theater I was going to try out an old method from back in the day . I will do a thin mix of pva water and black paint and put it in a plant mister (or even a washed out multi-surface cleaner bottle) and use this to "spray" undercoat the whole thing.

I used to do something like that to stop sand and gravel basing from flicking off when I painted it, should do that again really, had completely forgotten about it Thanks!!!

There are a few paints that are safe for foam. I would check with your local art store / craft store vs your DYI shops. You might also take a look at RC model shops. I found this link on google..

Also the Krylon H2O brand is marked safe for foam, but I have never personally used it.

Thanks for the help guys, especially that link ^^ , i will be ordering some of that.

Krylon H2O Latex

It won't melt foam, but i can only find it in glossy black, where matte black would be ideal.

Yes the website says it takes 15 minutes to dry, that is a lie! It is very watery, and to get good coverage you will need to spray it several times from different angles. It took about 6 hours to dry enough to be handled, high humidity didn't help...
