Before installing oak flooring, what is the necessary preparation step?

Preparing the subfloor before installing oak flooring is crucial to ensure the longevity and stability of the flooring. Cleaning the subfloor is a fundamental step, as any dirt, debris, or moisture present can lead to issues like improper adhesion, which can cause the floor to warp or develop gaps over time.

Installing 15 lb felt paper is an important part of the preparation process as it acts as a moisture barrier and provides a level of cushioning that helps to absorb sound and prevent damage. Overlapping the felt is necessary to ensure there are no gaps where moisture could penetrate, protecting the oak flooring from potential water damage.

This preparation step contributes significantly to the performance and durability of the flooring installation, ensuring that it remains level, looks good, and stands the test of time. Other options focus on various aspects, but they do not encompass the comprehensive preparation required for oak flooring installation.
