Suitable for both new and existing interior spaces, Porta Contours are made from sustainable and responsibly sourced materials and are fast and easy to install by one person. They can be fixed directly onto prepared plasterboard, timber, steel, brick, or masonry wall surfaces. 

Contours are available in a range of textured designs to create calming atmospheres or vibrant patterns. Made from durable, solid, and engineered timber, Contours are available in a range of species, including: 

Contours are perfect as a feature in any area of your home. It can also be used to clad joinery and create concealed doorways for a seamless finish. 

Porta recommends coating the lining boards on all faces and edges before installation in all areas of the home, including high-moisture areas, such as bathrooms and laundries.

Installing Porta Contours

To create a stunning Porta Contours feature wall over an existing plasterboard wall, follow the step-by-step instructions below.

Step 1 – Planning

Porta - Home Office Feature Wall8

  • Measure the height of the wall to work out the length of the Porta Contours timber lining boards you will need.
  • Measure the width of the wall divided by the cover to work out how many lining boards you will need. (The cover of each lining board is 78mm – excluding Plateau 39 which has a cover of 39mm.)

  • Acclimatise the lining boards in the same space the will be installed in, for at least 48 hours after delivery.
  • Ensure that the surface the lining is being fixed to is even, with a maximum tolerance of 3-4mm from flat. Use packers to ‘even’ the surface if the difference is more than this tolerance.
  • Locate the studs on the wall as they will be the fixing points of the lining boards.
  • The boards should be securely fixed at centres not exceeding 450mm.
  • Lining boards can be fixed directly to wall surfaces.

Coating the Lining Boards

Installing the First Board

  • Start from one side of the installation and work across the wall.
  • Apply construction adhesive.
  • Locate the first board and secure it by nailing through the face of the tongue side of the board.

Installing Subsequent Boards

  • Each following board will only need to be nailed through the tongue side when a secret fix application is used. Put the tongue nails in accurately and flush with the surface so the next board covers the head of the nail.
  • Progressively check boards are plumb or level (as appropriate) with a spirit level. Fit each board snugly and avoid over-cramping.
  • For spaces wider than 3m, an expansion joint of 10mm should be allowed.

Installing the Final Board

  • Measure the area for the final board.
  • If required, cut the final lining board to size and secure it by nailing through the face.
  • Alternatively, fill the remaining gap with matching timber trim.
