Flooring

  • Make sure all concrete, plaster and paint is dry before introducing the flooring to a room.

  • Ensure that there is no damp.

  • Acclimatise the flooring by stacking it in the room where it is to be fitted; leave it for two to four weeks before laying (four weeks in the winter). If the room is to have heating, make sure it is on, especially in the winter.

  • If you are fitting over underfloor heating we do not recomend using our stock flooring . Please speak to a member of staff about a special order of flooring dried down to a moisture content that will work better with your situation.

  • Always leave a 10-15mm expansion gap all the way around the edge and do not glue the edges of the boards together , so that each individual board can move on its own.

  • Make sure that the base to which you are fixing the flooring is dry, flat and sound.

  • Secure the boards to the base by nailing or screwing through the tongue or by using a recommended adhesive.

  • If laying the boards on joists, the ends of the floorboards must be joined on the joist..

  • Once laid, the floor will require filling and the  sanding. Best results will be achieved by using a combination of belt sander, orbital sander and edge/corner sander.

  • Vacuum the floor to remove dust and then wipe the floor with a cloth dampened in white spirit.

  • Apply recommended floor seal with appropriate applicator in even strokes along the length of the boards.

Cladding

  • Most cladding boards can be fixed with nails. When using oak  it is important to use stainless steel to avoid corrosion of fixings and blue staining of the wood.

  • Ring shank nails are preferable to normal wire nails because of their extra grip.

  • The length of the nail should be two and a half times the thickness of the board. The nail should penetrate the batten by at least 32mm.

  • Where boards are double-nailed, it is advisable to pre-drill over-sized holes to allow for some dimensional movement. In this instance it may be necessary to use fixings with larger heads.

Decking

  • Use a weed suppressing membrane to stop vegetation from growing up through the deck.

  • Space the supports or posts a maximum of 1800mm apart.

  • Joists should be a maximum of 400mm apart.

  • Leave at least 3mm gap between deck boards.

  • Ensure the deck frame is rigid, square and level (with a slight run off) before fitting the boards.

  • Use galvanised or stainless steel screws.
