Can you float a solid hardwood floor?

Yes, you can float a solid hardwood floor, but it's generally not recommended. Floating floors are typically designed for engineered hardwood or laminate, which have a tongue-and-groove design that allows them to expand and contract. Solid hardwood is more stable when nailed or glued down to the subfloor, as it can expand and contract significantly with humidity changes, potentially leading to gaps or buckling if floated.
