The versatility of floating floor installation allows it to be installed directly over various existing floors, including wood, concrete, vinyl tile and vinyl sheet, even carpet. That means you don’t have to pull up old flooring or deal with the mess of repairing a damaged one before installing your new laminate floor. Just make sure the subfloor is structurally sound, dry, clean and flat. An underlayment is recommended for laminate installation. Underlayment serves as a moisture barrier and will help quiet floors in areas with heavy foot traffic. It also makes your laminate floor sound and feel more like a real hardwood floor.
