Can I install the cork tiles over other floor surfaces such as ceramic tile, wood parquet floors, vinyl tiles or carpet?
No. If you have carpeting, vinyl, sheet vinyl, rubber etc., it will need to be removed and either the floor will need to be sanded until smooth or easier, a new plywood sub-floor be installed. (For example: Multi-ply plywood comes in sheets of 48x48x1/4″) The problem exists with the previous adhesive residue in the substrate. The new adhesive will not adhere to such a condition. Best results: use an all purpose type of adhesive and glue and fasten the new plywood in place. Follow the section concerning ” plywood sub-floors”. If you have ceramic or stone tiles and they are secure and not loose, float a cementious patching cement over tiles making the surface free of all deflections, grout lines and tile cushioning. The sub-floor must be flat and smooth and free of all paints, dirt, oil, grease and other foreign matter.
