Default Loudspeaker Foam Surround glue?

Hi All.

Hoping you can advise me.

I need to replace the foam surrounds and cones on a pair of Jamo Speakers I picked up recently for $15.

I've removed the remains of what crumbled away and will soon be ready to glue their replacements.

What's left of the special glue (white) I bought won't be enough to finish the job.

Do I need to buy more dedicated foam surround glue or is standard PVA wood glue (white glue, elmers glue) suitable.

This is issued with foam surrounds in the UK: Anita's Tacky PVA Glue - a poly vinyl acetate glue which dries colourless and remains flexible.

Need the proper glue and would not use general PVA.

QSR sells some in various sizes (50ml >) directly or via eBay.
Speaker Foam Surround Adhesive - Bostic (250ml) * Queensland Speaker Repairs

Speakerbits also sells some good glue for this purpose but their website seems to be MIA.

Doesn't your foam surrounds vendor add the suitable glue with the parts?

White (when wet) PVA glues is fine. Dries transparent and slightly flexible.

*Some* brands, meant for woodworking/carpentry include some mineral load (finely powdered talcum or industrial chalk) to give it some "solid contents" to make it stronger, more rigid, those dry whitish opaque and you donīt want them.
Buy whatever you find locally NOT branded "extra strong" or similar.

Also avoid the type sold for schoolkids use, and labelled as "washable".

A bonus to Mothers who must clean Juniorīs mess but those again include a load: starch.
When clothes are washed, starch grains absorb water, expand, and soften glue so itīs easily washed away, again you donīt want that.

IF you live in a large city, printer suppliers have a special "bookbinding glue" which is pure PVC (+ water of course), they apply it to cheap (non stitched) books or tear away writing pads and is meant to be flexible.
Often slightly dyed red or green, no problem since itīs only a dye, not solid pigment.

Before comitting to the real refoaming, you can draw a straight bead along some paper and let it dry overnight, then check transparency and flexibility.

Just checked, Anitaīs looks fine.
