  • Patent number: 9783997
    Abstract: Provided is a method of coating a PVC tile floor with improved fouling resistance, abrasion resistance, workability and gloss. The method includes forming wax coating having a plurality of layers (a multilayer structure) on the surface of PVC tiles, and coating the uppermost surface of a wax layer with a coating agent for polishing stone surfaces so that a protective coating film for primarily protecting the floor from the outside is formed unlike a conventional floor coating having a pure wax layer structure, thereby advantageously fundamentally preventing scratches and stains of the surface, avoiding detachment and sliding of films and greatly improving durability and safety in use, and, in spite of simplified coating process, preventing yellowing, securing superior gloss, and improving workability and processability as well as maintenance/conservation after working and economic efficiency.
