Before installation, always thoroughly read and adhere to the installation instructions and maintenance guidelines provided by the manufacturer. Laminate is typically available in easy-to-use interlocking planks that click together securely, requiring no nails, grout, or adhesives. This type of installation is referred to as a “floating floor”, because the laminate is not secured to the subfloor underneath. Laminate can often be installed over existing flooring, as long as the subfloor is sound, level and has no moisture issues. Proper maintenance of laminate flooring requires regular cleaning with a dust mop, broom, or hard floor vacuum, which will help prevent abrasive dirt from scratching the floor's surface layer. You can also use a damp mop with water only. If you need a more thorough cleaning, you can use a solution of water with vinegar or a non-sudsing ammonia. Do not pour liquid directly on floor. Although most brands of laminate are either waterproof or have a moisture-resistant topcoat, it‘s still best to clean up spills quickly. Never use a steam cleaner on laminate floors. To help prevent scratches from daily activity, it’s a good idea to put protective felt pads under the legs of furniture.
