Marmox insulation boards installation

Installation on concrete floors

• All traces of existing material should be removed to the concrete substrate, the floor should be level and dust free
• New concrete slab should be cured before fixing Marmox insulation boards
• Apply a bed of flexible adhesive to the concrete slab with a notched trowel, boards then to be thoroughly bedded in a staggered pattern, ensuring that no voids remain beneath them
• When the tile adhesive dry, tape all the joints with the fibreglass tape, then install the heating element, and tile with flexible tile adhesive
• Movement joints must not be bridged by the Marmox construction board

Installation on timber floors

• Timber floors must be rigid, checked for flatness
• The floor must be primed, before fully dry apply flexible cement adhesive layer with notched trowel, boards then laid (min 10mm) in a staggered pattern, fully bedded to ensure no void under the boards
• When the adhesive cured apply fibreglass tape to the joints and flexible tile adhesive
• After flexible tile adhesive dries secure the boards with screws and washers at the rate of 15/board with min 30 from the edge
