As the subject suggests whats the best adhesive to use when try to bond styrofoam? I've tried a PVA glue but doesn't seem to be strong enough

PS I've just joined so hello everyone!!!

Contact adhesive!

Evo stick! the brown stuff in a red tube!

I got some on my jacket last year, after washing and several rain storms, it still hasnt come off!

Hope this helps

willwoll100,

You may find that the solvent in the contact adhesive will melt the styrofoam. Here in the States I have used a product called Gorilla Glue. It's easy to apply and you use water as the catalyst to set the curing process in motion. I'm not sure whether you can get it in the UK but you might find it in a hardware store or B & Q.

The one problem with the Gorilla Glue is once the bottle is opened you have to seal it really well otherwise the moisture in the air will cure the rest of it. It's best to buy it in small amounts and use it all in one sitting. Make sure you clamp your foams together or put weights on top or the Gorilla Glue will expand and blow the joint apart. Once it is cured it is the toughest joint you will ever get.

Thanks for the reply but there are quite a few Evo-Stick products, does anyone know what it's called exactly?

Thanks

Cheers Steve A, I'll look into seeing if I can get some of the Gorilla glue.

Another question how much surface area will a 4oz bottle cover?

Check to see if it has solvents in it? Buy a small tube of Evo Stick red stuff and do a test piece, it is not worth getting it shipped from america!

Richardbarry.co.uk under adhesives, the stuff coventry uni uses is there for £57 but there is dunlop stuff for £8
A tube of it from b&q will be cheaper than that

Willwoll100,

The Gorilla Glue website indicates that the coverage is 1/2 oz per sqare foot so that tells you that you need very little to do the job, also when you navigate the site under Glue Finder select UK to find locations where you can buy the stuff.

Hi there are a couple of glue that can be used to glue polystyrene together. I used to build polystyrene patterns(press tool and foundry patterns)
If you are machining or casting the pattern you need to use these special glue.It is only special because it does not melt the styrene when you bond to piece together.Freemanns who make sheetwax make this glue or Burns & CO pattern supplys could stock this glue. It is quite expensive, I have used epoxy resin to glue sheets together.
If you any more help feel free to contact me
