In some cases, the type of subfloor you have will influence the choice of installation method. The sub-flooring can be pinned down to the concrete for sub-floor installations over concrete, allowing the hardwood flooring to be nailed on top. This approach is commonly used in new construction projects. It’s important to ensure the concrete slab is properly prepared, recessed in hardwood areas, or leveled to avoid elevation differences.
The nail-down method can be employed for non-concrete slab houses, such as those with plywood subfloors. This approach is suitable for both solid and some engineered wood floors, providing a secure and stable foundation for your hardwood flooring.
