it's taken more than a few coats of (Vallejo) paint to rid the pink bleed through. I started with grey primer, then a few different coats of greys, light & dark. in the process, some detail has been lost to my disappointment. but there may be a better way. any help appreciated; thanks.

I assume you are talking about extruded styrofoam insulation board. Dow Corning also makes it in light blue, which I find much easier to cover with a coat of paint. But when you are talking about "detail" you must mean that you've carved it into a shape or a model of some sort-- you could have just started with white foam. I use the type found as fresh meat packaging from the meat department in my local grocery store, the kind that "trays" of hamburger or steaks come on. It's easy to carve into walls, pavement, etc. and easily painted with acrylics or light enamels. And you get to enjoy a hamburger or a steak while model building! Need it thicker?--glue two sheets together with Elmer's or other white glue.

HI guys -

I use the pink foam often enough - After some practice, you can get nice results, and havent had problems with painting.

Below is before it was primed - I use vallejo primer:




and here it is after prime and paint:



I haven't had any problems with the pink part showing or bleeding through , but have had trouble if I've use a marker on the foam along the way (laying out etc). I can generally just paint over the bled out area once the topcoat is dry.

Good luck!

Nick

great job. I did mix some airbrush medium & a couple of drops of retarder in with the V-primer in an attempt to preserve the detail so maybe I over-did it.


first attempt, so i'll go at it again and see if I can improve.


thanks

Nice work on that, I just got the books from the guy in Hungary that uses all the foam stuff. Good books there.
Well to make a long story short I bought a sheet of foam to try ,will use my table saw to cut into smaller pieces.
I like that, all airbrushed you say?
Good job.


Cheers

My work doesn't hold a candle to what Nick has done; but to give you a different option you might try latex house paint. That is what I have used for a couple of years now, I picked up a tester jar of flat black from the DIY store (Home Depot) for about 3 bucks and some chip brushes from Harbor Freight for about a buck (I use a boring beige for desert dioramas). I thin it down with a bit of water (about 75% paint when thinned) and paint it on.The latex gives a great tight surface that is impervious to enamels and other 'hot' paints and finishes when fully dry (about 24-48 hours). Just another idea, take it or leave it as you wish. Good luck!
Cheers,
Rick


Here is one with the flat black latex paint.


And here is one with sandy beige color.

nicely done. really like the little pigeon coop with the fly cages.

the black basing seems a common starting point for a number of things (figures, mountains, et cetera) yet I've not had the courage to try it, always skating on the side of caution. but there does seem to be some merit in trying.

any chance you would share how you carved the rocks in the bottom picture? that's my next challenge!

thanks

Ha Ha, that's a good one!! Wish I had those kind of skills too!

I didn't carve them at all, they are pieces of 'tan bark' from the fire pit in the backyard. I picked up five or six pieces that looked like that layered sandstone you see out in the desert, cut them in half and attached them to the front of the insulation foam. Primed and painted and there you go.
Glad you liked the rolling Signal Corps pigeon coop! I saw one at the D-Day Museum down in New Orleans a couple years ago and got the bug to build one. One of my favorite builds.

Cheers,
Rick
