Default Attaching fabric to soundboard, best glue?

I'm restoring a GEC BC 5445 which has a fabric covered sound board.

The fabric came away easily with some soapy water so I reckon it was attached with a water based glue.

To reattach it, whats the best glue to use, I was considering PVA glue which should dry out clear?

thanks
Ray

I use latex based fabric adhesive aerosol spray, but you can also get adhesive in tubes.

Wilko for example sell small (20 ml) tubes which dry clear:

Hope that helps.

Excellent, I should be able to get this locally in a fabric shop.

Many thanks David.

Epoxy done right is a time tested repair technique. If you apply the layers "hot" i.e. before full cure has occurred, the layers will chemically bond to one another and become as one. Quicker too.

Copydex or PVA. Use sparingly to avoid oozing up through the fabric. Similarly don't press down too hard when fitting the fabric, enough to ensure that the glue is on both surfaces is sufficient.

PVA seconded. I've covered large speaker cablinets (for bass guitar) with something called carpet. Basically use a small decorating roller to put on a thin layer of PVA.

The other thing I've used is spray adhesive. Thin layer on the cabinet, let go tacky, press on cloth. After masking areas you don't want the spray going of course.

Water soluble PVA gets my vote. Dries clear and can be soaked off in future if needs be or if you make a mess of it the first time.

I haven't found copydex to be durable, at least when gluing hessian carpet edging. Stuff I glued with traditional evostik more than 50 years ago is still sound. I hope they haven't changed the formula significantly in the mean time.

The main benefits of fabric glue is that it can be used without mixing or diluting, it doesn't need clamping as it sticks right away, but still allows the fabric to be stretched to position it exactly before it fully sets, so the warp and the weft can be adjusted to be straight and properly lined up. It's also flexible, colourless and waterproof. No doubt other adhesives can be pressed into service, but it makes sense to me that when sticking fabric, to use fabric adhesive which is formulated for exactly that task and 'ticks all the boxes'.

Hobbycraft do a 60ml bottle for only 2.00 which gets good reviews.
