Acoustic Tiles


Senior Member
Hey guys!
I bought some acoustic tiles off ebay awile ago and fixed them to my wall with blu-tac because we wanted a method to attach them so they wouldn't rip the plaster off.
Just now they have started to become very loose and some even fall.
Just wondering if you could reccomend an adhesive to attach the tiles without ripping the plaster off if they need to be removes?

P.S I can't tac them or drill them into the wall :(
