Vinyl flooring is a popular choice for high-traffic areas at home and in the workplace. Many people consider it one of the most desirable materials. Vinyl can also look beautiful. It comes in many colors and patterns. Some options even mimic the look of stone, tile, or wood. But what happens when greenish or grayish stains appear under a vinyl floor?
When grayish stains appear from the bottom up on a vinyl floor, it is most likely signaling that mold or mildew is present. As most people know, mold and mildew thrive in moist, dark places, so if they are present in the vinyl, it’s a sign that there is too much moisture in the substrate. This can come from an ineffective or non-existent moisture barrier or a leak from somewhere nearby. No matter what the source, it’s not good to have moisture trapped underneath the vinyl.
Unfortunately, installers can make several mistakes when putting in vinyl that can lead to mold and mildew growing. It’s important to do everything possible to make sure that the moisture in the room and in the substrate is under control before laying the finished flooring.
