What is the proper way to attach base shoe molding on a hardwood floor?

Attaching base shoe molding correctly is essential for both aesthetics and functionality. The proper method involves nailing it to the baseboard only. This technique allows the base shoe to cover the expansion gap typically found between the hardwood floor and the baseboard, providing a clean and finished appearance without interfering with the floor's movement.

When base shoe molding is nailed to the baseboard, it remains relatively flexible, which is important in accommodating natural expansion and contraction of the hardwood due to temperature and humidity changes. This flexibility helps prevent cracking or splitting of the molding over time. Additionally, by securing the molding to the baseboard instead of the floor itself, it avoids any potential damage to the hardwood surface when adjustments or removal might be necessary in the future.

Using adhesives or screws can create issues with rework or floor adjustments, as they can bind the molding too rigidly to the floor, leading to potential damage if the floor needs to move. Likewise, staples are not commonly used for this application, as they may not provide adequate support, which can lead to loose or detached molding over time. Thus, nailing the base shoe to the baseboard is the most effective and universally accepted method for installation, ensuring both stability and ease of maintenance.
