How to Ensure a Stable Base for Floors with Underfloor Heating?

Installing flooring over underfloor heating requires specific preparations to ensure stability and durability. Temperature fluctuations can put stress on the subfloor, leading to cracks or detachment of the flooring. A suitable primer plays a crucial role in optimizing adhesion and protecting the subfloor from these effects. Additionally, a primer helps bind dust and creates an even base, which is essential for a successful underfloor heating installation.

Bona D501 Primer is suitable for underfloor heating and prevents damage from temperature changes.

Bona D501 is a high-quality, one-component dispersion primer specifically developed to meet the demands of underfloor heating systems. This primer is vapor-permeable, helping to minimize moisture-related issues and prevent damage caused by temperature fluctuations. It is suitable for both absorbent and non-absorbent subfloors, including cement-based floors, calcium sulfate floors, and chipboard. Bona D501 dries quickly (within 1-2 hours) and forms a stable, dust-free base that significantly improves the adhesion of parquet adhesives such as Bona Quantum or Bona Titan. The product is easy to apply with a brush or roller, ensuring user-friendly application and consistent results.
