How to protect floors from moisture problems?

Excess moisture in the subfloor can lead to considerable floor damage, like warping, cracking, or the loosening of floor coverings. In particularly humid areas, such as basements or rooms with changing humidity levels, it is crucial to safeguard the flooring. A primer with moisture-regulating abilities can reduce the effects of moisture and offer a stable foundation for further installation. It stops moisture from penetrating adhesives or floor coverings, significantly enhancing the longevity and durability of the flooring.

Bona D501 primer is vapor-permeable and provides moisture protection without affecting adhesion.

Bona D501 is an excellent primer for humid spaces thanks to its vapor-permeable nature. This one-component dispersion primer prevents moisture intrusion into the flooring while readying the subfloor for robust adhesion with parquet adhesives. Bona D501 binds dust, evens out minor irregularities, and dries swiftly, streamlining the installation process. The product suits both absorbent and non-absorbent subfloors, such as those based on cement or calcium sulfate, and ensures a reliable and resilient foundation, even in damp conditions. With a drying time of just 1–2 hours, Bona D501 is also remarkably easy to use.
