I had vinyl flooring professionally laid 2 years ago. Now it is covered in black stains and a faint pink discolouration. We have the same flooring in two different rooms - in the kitchen (which is stained) and in the downstairs bathroom (not stained) which is next to the kitchen.
Today i pulled up the flooring to see what was causing the stains on the kitchen floor. The glue was still as wet as the day it was laid. The bathroom however, whilst a bit sticky, was pretty much dry. Does anybody know why this has happened?
