We had the Charcoal Parquet flooring fitted in February 2014, by June 2015 we noticed a yellowish staining on the flooring between two carpets that we had in our conservatory. The floor was cleaned every week, carpets moved back, and no spillage was on the floor. However, we did not have blinds in the conservatory for the first 2 years and believe that this could be caused by sun damage. We have other lighter colour change around the conservatory flooring. Harvey Maria have been to see this recently after years of complaining, and have concluded that it is caused by rubber backed carpets. Neither of the rugs are rubber backed so not sure how they reached this conclusion. We need to see if anyone else has had this problem. My photos that show the gap between a runner and a larger rug is too large to post but the fading is similar in colour to old, faded paperback books. Hopefully someone could help us as we were not warned of such a colour fade in such a short time. We have been told by another LVT producer that their tiles would fade lighter in the sun. Adhesive and cleaning have been cleared as a cause of this discolouration. Any help, advice would be appreciated.
