Before You Start
For this project, we decided to forgo power tools like a mitre saw and enjoy a bit of a challenge instead. If you also feel up to it, you can opt to use a hand saw and a mitre box to get the job done.

Start with a Sketch

  • 1.1Measure the installation wall and plan your design.
  • 1.2Decide how many panels you need and how wide the spaces should be.
  • 1.3Use ratios of 1/2 and 1/4 to subtract the spaces from the total width.
  • 1.4Use ratios of 1/3 and 2/3 to subtract the spaces from the total height.

Locate the Studs

  • 2.2Make a mark on the wall where the studs are.

Pro Tip

If nailing your mouldings into the stud isn’t an option, glue can help ensure that everything is solid.

Measure Out and Mark the Guide Lines

  • 3.1Use the bottom left corner of your plan as the starting point.
  • 3.2Use a bubble level to draw the plan on the wall.

Cut the Mouldings

  • 4.1Use a mitre box and a hand saw to cut all of the mouldings at a 45° angle.
  • 4.2When measuring, go from the outside corner of the moulding.
  • 4.3Inverse the angle of the cut on each end.

Nail the Mouldings

  • 5.1Install the first moulding by nailing it through the centre, allowing it to rotate.
  • 5.2Ensure that the moulding is level and use additional nails to secure it in place.
  • 5.3Follow your guide lines to complete the installation.

  • 6.2Apply latex to the nail holes and around the moulding edges using a caulking gun.

Pro Tip

Want contrasting mouldings? It is much easier to paint them before installing them. To choose the right colour for your decorative new wall, just consult the Colour Selector by SICO.
