As many of you have found out using just spray adhesive behind your Old Headliner will not resolve your problem.
The Original Headliner Material from the Manufacture is only 1/8th inch thickness including the Cloth and the Foam Backing combined. From age and heat the foam backing as you have experienced has deteriorated and become a powder form and the cloth has nothing to attach to!
By spraying a Wet Spray Adhesive on the back of the cloth with out the foam backing in place will only bleed through to what you feel is the cloth material in good shape on the interior exposed side, but now you have a bigger mess than before you started trying to fix your old headliner from falling.
I would recommend purchasing a box of regular thumb tacks and tack it up until you can either replace the old Material with New Material in which includes the New Foam Backing your self or have a professional shop take care of the problem for you.
Cutting a small hole into your Headliner & Injecting Adhesives with a syringe does not work!
Spray Adhesive on the back side of the cloth with out the foam backing does not work either!
We have the OEM BMW Materials in stock, these are not after market materials found here in the USA at most Upholstery Shops or supplies houses or even Jo-Ann Fabrics. These are the Original 1/8th inch Headliner Materials that were installed a the BMW Plant when the cars were being Built.
