So I've covered how to remove a mic's grill screen, cloth, or silk and how to rinse it out. Let's put it back in...

I've seen loads and loads of mics -vintage and newer- bearing the obvious scars of 'home improvement' -and I'm not talking about Tim Allen here. One of the clear signs of hobbyist mic mayhem is grill fabric laying lazily back from the grill, drifting between the mic's element and the inner frontal surface of the grill. Let's face it, prayer won't keep it where you want it to stay, but a light shot of a spray adhesive will.
Spray glues are nothing new, and there are a number available that will do the job. There are some that target the photo and graphics market, utilized for paste-up (tacking printed or photo bits onto a background surface) that smell just like the 'rubber cement' of old. There are others that cover the range of 'contact cement' uses in strength. Either of these will work and provide superior results.
When you're ready to reassemble your project mic, take your pre-cleaned grill and its cloth, make certain you know exactly how the cloth will be positioned within (no second chances with the 'contact cement' category), and step outside to spray. Put a latex or nitrile glove on the hand that will be holding the grill -or put it on a background of cardboard. Apply a very light spray (a dusting's all it needs) to the inside of the grill. Let it "gas off" for several minutes to allow the glue to tack-up & solidify. Now, place the grillcloth into position using tweezers, needle nose pliers, or forceps. Happy with its position? Run your finger around the inside of the grill over the surface of the cloth, pressing it against the tacky tines of the grill. Just like a good dog, it'll 'STAY'!
