Self-Adhesive Tiles Over Pergo

Q: I just put down my new Pergo flooring my house and it looks beautiful! I was wondering if I can stick 10 self adhesive vinyl tiles on top of Pergo laminate. It is for decorative purposed and am putting the tiles in front of a gas fireplace. It is going to be around 3 feet wide and 3 feet long. Is it o.k. to lay down the self adhesive tile on top of the Pergo?
Thank you,
Laura
A: The short answer here is “no,” but let me explain why this would not work. Since your Pergo laminate is a floating floor, this means that as you walk on it, it will flex slightly. Self-adhesive tiles are meant to be installed directly to a subfloor and are not built for movement to occur underneath them.
This means that if they are adhered to your Pergo, as the Pergo moves, the tiles will begin to flex more than intended, which will causes cracking or peeling. Basically put, the tiles will fail. Also, Pergo laminate is not meant to have other flooring installed over it, making it unsuitable as a subfloor, so you would void any warranty on both the Pergo and the self-stick tiles.
Your best bet here would be to either leave the Pergo, remove some of the planks and build a small area for the fireplace, or find a rug or mat which would be suitable to place over the Pergo, under the fireplace.
