When dealing with significant uneven spots in a subfloor, the correct approach is to fill them with leveling compound. This method is essential for several reasons. First, a level subfloor provides a stable and secure base for the flooring material, which is crucial for both aesthetics and functionality. If the subfloor is uneven, it can lead to issues such as cracking, warping, or failure of the flooring material over time.

Using leveling compound helps to create a smooth and uniform surface that minimizes the risk of these complications. This compound is designed to flow into low spots and cure to a hard, flat finish, effectively addressing any dips or rises. It is especially useful in preparation for installing various types of flooring, including tiles, vinyl, laminate, and hardwood.

In contrast, ignoring the uneven spots can lead to serious installation problems and reduce the lifespan of the flooring. Covering them with carpets or using thicker flooring may not resolve the underlying issue and can result in visible imperfections or inadequate support for the flooring system. Hence, applying leveling compound is the most effective and industry-recommended solution for preparing an uneven subfloor.
