For best results, The Visual Magnetics Graphic System should be applied to a smooth hard wall surface as the MagnaMedia print film and InvisiLock magnet are smooth and flexible so a bumpy wall surface will show through to the final graphic surface. A heavily textured wall should be smoothed over with a filling compound and/or sanded smooth before applying the ActiveWall primer. Another option is to hang or mount commercially available rigid panels in the designated graphic areas prior to installation of the Graphic System or cover the wall surface with smooth paneling.
