Acoustic Foam

Hi!

All the glue I have tried over the years has failed. Velcro is what i've had best results with for acoustic foam.

Put the foam on the outside of the grill. Looks clean and nice, and you don't have the issues with glue showing.

Spray the back side of metal with super 77 . Let it tack up but not dry. Apply the foam. If you don't care about consemtics you could do a very light dusting to the foam also. That would ensure they bond. But one side should be enough .

This one crops up on various forums from time to time!

My method is this:

Take some evostik, bondloc or similar polychloroprene based adhesive.
Thin it down using xylene or toluene paint thinner from the paint shop (must be done outside). Dont go nuts but make it like single cream or thin honey.

Note: white spirit, alcohol or turpentine does not work.

Using a mini polythene foam roller, (the coarse white ones - smooth polyurethane will dissolve) apply the glue all over the rear of the grille.
Using a rag dipped in the solvent, wipe any drips of glue that have made it through the holes (loading the foam roller with only a small amount of glue avoids this).

Apply the foam or cloth, and press it down carefully all over. It should stick wherever it touches.   

Doing this avoids the spider-web effect of aerosol carpet glue (messy) and the risk of leaving little patches with no glue on them which sag later.

Note that it's only good for unpainted or powder-coated grilles. If you spray painted it yourself first, you might find the foam or cloth comes off and brings the paint with it!

edit: mix the glue in a metal or polythene container or it'll melt. I use an old linbin storage box.
