The install started on Saturday with the blower/vacuum behind the liner running until Monday. Before we started the initial hose filling, the liner was flush with the corners. By Monday afternoon the liner bead in one corner had popped out and there was air behind all of the corners. Installer got the liner back in the track on Monday but didn't redo the vacuum. When I asked about the gaps, I was told the air gap is normal and that the loose vinyl will not wear any differently than if it was flush with the wall. The gap starts at the top/coping and continues to just below the decorative border.
Is this true?
Also, the liner manufacturer mentioned that a glue should have been used in the corners. I do not believe there was any adhesive used.
If this is a bad install, what should I ask the installer to do to make it right?
Thanks for your help,
