• Is the BEALSTONE® coating compatible with underfloor heating?

    Yes, this type of traditional heating technique, with screed and insulation, is fully compatible with the BEALSTONE coating. As with other types of coating, precautions must be taken to ensure correct operation, with regard to the substrate and temperature settings.
    For application, the screed must be dry and clean (see technical data sheet on www.bealinternational.com) and the heating must be switched off 4 days before application.
    When the substrate is made up of materials of a different nature, which are not stable and/or have joints (e.g. tiles, OPAL system, etc.), it is imperative to take the necessary precautions to avoid, as far as possible, any movement due to expansion, differences in surface and internal stresses and shearing, i.e. to choose :
    – Reinforcing net or reinforced textile mat at junctions
    – Reinforcement net to be embedded in the first technical layer.
    – Special textile mortar adhesion mat in the corners
    – Uncoupling membranes over the entire surface

    As with conventional underfloor heating, the maximum temperature should be 28-30°C.
    Start-up (in steps of 2 to 3°C per 48 hours above the substrate temperature) once the BEALSTONE® product is completely dry (minimum 7 days). After the heating system has been switched off, it is always put back into service by temperature increase in steps of 2 to 3°C / 48 hours.
