styrofoam ftw? now with WIP
« on: Aug 08, 2010, 10:06 PM »
So I am making a backpack and I have found this perfect piece of Styrofoam but the real question is what can I do to coat the material to prevent the spray paint from eating through it? Anyone?

Thin down some elmers glue with water and use a brush to coat it.

Use it as a base template but dont use it for the build. Make it out of cardboard and fiberglass it.

its a really thick vacuum form foam for packing, any thought on fiber glassing that? or do you think it'll melt through it as it heats up?

Nosaj is using it for a shield for his son. I've seen it use on verps and the like. Make sure the glue seals well and you sand well too.

Speaking chemically, they are virtually the same once impregnated with elmers and fiberglassed. Pink foam is just a little tighter packed in the 'cells' of foam, is all. Give it some extra love with the seal and fiberglass treatments and your fine, or you could try to template and recreate in pink foam or cardboard.

Just remember when sealing the foam you're going to want to do several layers of the Elmers before the fiberglassing.  If you have one small spot that the fiberglass can seep through it'll melt the entire piece.  Wish ya luck and I look forward to seeing your W.I.P.  ;D

The Fiberglass resin alone will eat and melt that styrofoam quick, fast, and in a hurry, and could even pose a fire hazard.  Resin gets very Hot when it is curing, that is why you should only mix it in paper or metal containers.

I would suggest not using styrafoam at all. as A'den suggested, you can use it as a template for cardboard, or plastic.  At the end of the day, Styrafoam will just end up looking like styrafoam (IE- cheap)

Spanner.... I've worked with styrofoam and pink board for years doign 40k terrain. The elmers glue seals it against the fiberglass reacting and melting it and causing any hazards. And once it's covered in fiberglass and sanded, bondo'd, and painted, if it's done right with the proper attention, it won't look any different or worse than anyone who builds something out of carboard and fiberglasses it, or hammers flat sheets of metal or anything.

Styrofoam props tend to look cheap and like crap because, quite frankly, the largest amount of people who use them are looking for a quick way out, and a cheap way out, and don't bother to put in the proper effort and work.

Honestly why not put a layer or two of paper mache or Water Activated Paper Packing Tape then fiberglass? maybe try out the Aqua resin to see if it will work as well..

Strength.. Paper mache will fall out. Aqua resin, as far as I remember, it still an exothermic reaction, and thus will melt. Water activated packing tape could work, but like Nosaj said... You get one gap (easy to do with tape) or soak through (in the case of the tape) and it's all shabs up.
