How to Protect Floors from Moisture Problems?

Moisture issues in the subfloor can cause significant damage to floors, such as warping, cracks, or loosening of floor coverings. Especially in humid environments, such as basements or rooms with fluctuating humidity, it is essential to protect the floor properly. A primer with moisture-regulating properties can minimize the impact of moisture and provide a stable base for further installation. It prevents moisture from seeping into adhesives or floor coverings, significantly increasing the durability and lifespan of the flooring.

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

Bona D501 is an ideal primer for humid environments due to its vapor-permeable properties. This one-component dispersion primer prevents moisture from seeping into the flooring while preparing the subfloor for strong adhesion with parquet adhesives. Bona D501 binds dust, levels small irregularities, and dries quickly, making the installation process efficient. The product is suitable for both absorbent and non-absorbent subfloors, such as cement-based and calcium sulfate floors, and provides a stable and durable foundation, even in humid conditions. With a drying time of just 1–2 hours, Bona D501 is also highly user-friendly.
