Paneling

Recommendations for MDF tongue and groove panelling

  • Always follow best building and painting practice guidelines (refer to BRANZ).
  • Prepaint panelling before installation/fixing to avoid lap lines as product contracts with ambient temperature (timber products will take on and release moisture consistent with the prevailing conditions). See also the EcoEdge Finishing & Painting section
  • Avoid fixing scotia or ceiling covers to ceiling panels as any movement of one will affect the other (same building principle as floating floor system)
  • Face nail or staple at 450mm centres at least 25mm in from an edge or corner and at least 25mm fixing penetration into sub-construction
  • Use brad panel pins for concealed fixing taking care to angle through the back edge with the and pushed flush
  • Use contact or wallboard adhesive in combination with nailing (refer glue suppliers guidelines on use)
  • Allow for an expansion gap on each end of the panel. Minor movement may occur particularly when the panelling is fixed to a sub frame batten and frame.
  • A new house build or renovation using timber will take time to settle to its environment. Some movement caused by moisture shrinkage can be expected but can be minimised. Avoid the build area to become damp and cold and take care to slowly heat the house after building and painting is complete. To minimise heat shock, properly ventilate the home by opening doors and windows during the heating process. Slowly increase temperatures over several days and do not exceed 60 C at any time during this process (the ceiling is generally the hottest point).

Must not be used in the following . . .

  • Around wet areas such as baths, saunas and swimming pools
  • Outside or in exposed to weather areas
  • In areas where temperatures exceed 60°C (e.g. ceiling areas close to flue’s, high-temperature heat pumps/central heating).
  • In direct contact with concrete or masonry surfaces unless separated by damp proof course 

Please note:

Wood fibre is generally hygroscopic which means it readily absorbs moisture. Shrinkage of the product may occur if the product
is exposed to damp and cold or overly humid and hot conditions. Ensure product is stored in dry conditions at least 15cm above a
concrete or masonry surface.
