It is particularly well suited to subfloors incorporating underfloor heating systems, where strong bond strength and stable surface preparation are critical.Role In Underfloor HeatingWithin an underfloor heating installation, correct subfloor preparation is essential to ensure efficient heat transfer and long-term floor performance. Eco Prim T Plus plays a key role by:Enhancing the bond between the subfloor and levelling compound covering heating pipes or heating cablesMinimising air bubbles and pinholes in smoothing layersSupporting even curing across heated areasHelping to prevent delamination caused by thermal movementWhether used above wet underfloor heating pipework embedded in screed or over electrical underfloor heating mats prior to encapsulation, this primer helps create a stable and reliable base for the finished floor.GuidanceEnsure substrates are clean, dry, sound and free from dust, grease, laitance or loose material before application. Apply evenly by roller or brush in accordance with manufacturer instructions. Allow the primer to dry fully before applying levelling compounds or adhesives.Underfloor heating systems should be commissioned and tested in line with industry guidance before floor preparation begins, and heating should remain off during application and curing unless otherwise specified by the system manufacturer.Technical OverviewWater-based acrylic primerLow VOC and low odour formulationInternal useDesigned for use beneath smoothing compounds and adhesivesCompatible with common cementitious and calcium sulphate substratesMapei Eco Prim T Plus is a dependable choice for professional floor preparation, helping ensure a strong, durable foundation for underfloor heating systems and high-quality floor finishes.
