How to ensure a reliable foundation for floors with underfloor heating?

Laying flooring over underfloor heating necessitates specific steps to guarantee stability and longevity. Variations in temperature can strain the subfloor, potentially causing cracks or disconnection of the flooring. An appropriate primer is vital for enhancing adhesion and safeguarding the subfloor from these impacts. Moreover, a primer binds dust and forms an even surface, crucial for a successful installation of underfloor heating.

Bona D501 Primer is ideal for underfloor heating and guards against temperature-induced damage.

Bona D501 is a superior, single-component dispersion primer crafted specifically to cater to the needs of underfloor heating systems. This primer allows vapour to pass through, which helps reduce moisture-related problems and guards against damage from temperature shifts. It is compatible with both absorbent and non-absorbent subfloors, including cement-based surfaces, calcium sulfate floors, and chipboard. Bona D501 dries rapidly (within 1-2 hours) and creates a firm, dust-free base that significantly enhances the bonding of parquet adhesives such as Bona Quantum or Bona Titan. The product is straightforward to apply with a brush or roller, ensuring an easy application and consistent outcomes.
