Bad Rug Pad Choices
PVC rug pads - Certain types of PVC rug pads will “sweat” and end up marring or discoloring a hardwood floor. This is caused by the pad’s inability to absorb or release moisture. Also, in hot humid climates, the oils in PVC pads can react with a floors finish, “sticking” to the floor and causing permanent damage.
Synthetic Rubber or Latex rug pads - Although they may last for a few years, these pads will eventually break down and turn to dust. Anyone who has ever removed an old-style waffle pad when replacing old carpet will have experienced this break down effect. This occurs because the makers of these pads use lots of clay fillers during the manufacturing process. These clay fillers will break down and turn to dust over time.
