I have been installing the shower room and toilet of late. I have been doing it one wall at a time. Now the 3rd wall is in I have a problem in sealing the wall to the rear wall and shower tray. The gap is to tight to to get the gun in and my finger to finish it.
I have a plan that involves 2 nozzels a length of tube, a stick and a plastic washer. Watch the next blog to see if it worked.
