Can cork tiles be installed over other types of floor surfaces such as wood parquet, vinyl tiles, carpet, or ceramic?
The answer for this is, no. Carpeting, vinyl tiles, sheet vinyl, etc., will have to be completely removed and the subfloor sanded until smooth or a new plywood sub-floor will have to be installed prior to installing the cork tiles. The adhesive used to apply the cork will not adhere to other surfaces, resulting in the tiles pulling away. For ceramic and stone tiles, first you must ensure that non of the tiles are loose, then you will have to float cementious patching cement over tiles to fill in all deflections, and grout lines. It is vital that the subfloor be smooth, flat, and free of all defects as well as clean of all paints, dirt, oil, grease, and other foreign matter. If the subfloor is not smooth and free of all defects, these can transfer through the cork tiles.
