Spray adhesives

Looking for alternatives to 3M 77 spray adhesive for tape covering- anyone used anything else they can recommend? Don't forget its gotta be foam safe!

As in EPP foam, or polystyrene type foam. If t is the former, then try some contact adhesive, thinned down till it is like milk. Brush it on, leave it to dry till it is on the dry side of tacky, and tape will stick to it like the proverbial to the blanket. I normally use Evostik and Evostik thinners, but any decent contact adhesive will do the trick.

I've always found spray glues to be rather messy, and they tend to come loose easily, I thinck brushed on thinned contact adhesive acts like a primer that the tape glue can really stick to.

That said, I would use laminating film instead, much better in all regards...

what you have described Andy is for EPP

Ebay or try the local sign making shop

Indeed it was. If it is polystyrene (expanded or extruded) then using a solvent free contact adhesive watered down works well. Copydex is a commonly available one, and it normally doesn't need much watering down too....

there you go Ben

Thanks for the answers - does copydex and water not go too well on EPP then?

It does work, but doesn't work as well as solvent based stuff. The bond between the adhesive and EPP is not quite as easy to dislodge with the solvent based stuff.

Most solvents that are found in contact adhesives are okay on EPP, certainly EvoStik ones work fine. Generally speaking, it is the polystyrene based foams that can't cope with much solvent exposure at all. EPO (Expanded Polyolefin type foams) are sometimes resistant depending on the solvent strength and type, but EPP is pretty hardcore really.
