Laminate requires a perfectly flat surface to prevent clicking sounds or joint failure. The subfloor should be checked for moisture content and elevation variations. After cleaning and leveling, the appropriate underlayment is installed to provide a moisture barrier and a slight cushion, which aids in floating installation performance and long-term joint integrity.
