Fixing to concrete floors.

•  The concrete surface must be clean before applying the board.
  
  
•  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.

 Fixing timber  floors.

•  Timber floors must be rigid, checked for flatness.
  
  
•  The floor must be dry. Apply suitable tile adhesive layer with notched trowel. Boards then laid in a staggered pattern, fully bedded to ensure no voids remain under the boards. 
  
•  When the adhesive dries apply fibreglass tape to the joints.
  
  
•  Secure the boards with screws and washers. Use 15 screws per board with min. 30 mm from the edge. Then install the heating element and tile using flexible tile adhesive.
