Definition: Deglazing PVC (polyvinylchloride) pipe means simply to roughen up the sections that will be bonded. The solvent used for PVC does not adhere very well to smooth surfaces, so it is necessary to use fine sandpaper to deglaze the surface. So, deglazing is just a fancy word for roughening up slick PVC surfaces.
