How do you finish corners with decorative wall cladding?

How to finish corners with timber planks

The question is often asked for us to help installers and specifiers understand how our decorative wall products can be finished on corners.

We’ve outlined some options so you can see for yourself how it can be done.

VidaGroove & PurePlank Timber wall cladding

Since our range of timber can vary in age (some reclaimed timber is up to 60 years old!) it also varies in hardness and durability.

There are three common ways edges are finished:

1. 45 Degree Mitre Cut: The most visually unobtrusive way to finish an external corner is with a 45deg mitre cut.

Sometimes softer, more textured timbers will not achieve the best result over time with this method. For these timbers, use one of the methods outlined below.

  • Firstly sample this timber edge finish by cutting two pieces at 45degs, and replicating a 90deg corner join. Does it come up visually as the best option, i.e. is it smooth enough to leave a consistent surface?
  • Does this finish suit the environment? In high use retail environments, we would recommend another option below to guarantee longer term durability.

(Note: some textured timbers may require additional matching filler/caulking once joined to enhance the finish)

Some examples:

2.  Strip clashing: This provides a durable edge, as the bar takes any impact rather than the timber. Suited for high use retail, hospitality environments.

  • Prepare clashing lengths to match depth of timber plank edge cut at 45deg (i.e. PurePlank is 14mm thick, when cut at 45deg this becomes 20mm). You want to ensure any impacts strike the clashing not the timber
  • Cut pieces of timber plank at 45deg, to replicate 90deg corner.
  • Work up one side of the vertical wall as shown below
  • At completion of one wall face, insert the bar, gluing to cut edge of the 45deg join
  • Complete cladding of the next wall face, gluing plank ends as you go to the clashing. Normally work upwards from bottom of wall.

3. Beading strips made from cladding material: This works best with our solid timber planks, and works particularly well at wall ends and external corners, maintaining the complete timber look.

These can be made to order upon request.

  • The size of the timber beading should be detailed on plans, this typically equates to measurements the same as the depth of the wall cladding planks. i.e. 20mm x 20mm
  • Fit cladding to wall following our guidelines supplied, allowing for measurements of the beading at each external corner and/or wall ends.
  • Beadings can either be glue fixed, or brad nailed after cladding installs to the flat wall surfaces.
