Here’s some balau cladding work we did on the ceiling in the reception of a new office building in Umhlanga Rocks.
We used 19 x 30mm strips of balau which we ripped from a standard 19 x 68mm balau deck board. We started off with a treated pine frame or structure on to which we attached these balau strips. Being a ceiling it was important to ensure that our structure didn’t fail under the weight of the balau. Balau, being a very heavy and dense wood, can get quite heavy when suspended from a ceiling. Secure fixing points, and enough of them, are necessary to ensure it doesn’t fail.
It was very important to do this as neatly as possible as it is the reception area and as such is visible to all visitors as they enter the door. Care needs to be taken to ensure that gaps between boards are uniform and that the boards are parallel to each other. Also it is important to get the total structure to line up parallel with walls and corner of walls and slab above. It becomes unsightly when these don’t. At times the corners of walls may not be perfectly square and adjustments then need to be made so that the ends of the timber structure are at least parallel to the adjacent wall even if it means the structure itself isn’t square. Small adjustment can be made to the gaps between boards to compensate for this. 1mm on each end of a gap won’t be visible to the naked eye but will result in a 20mm “gain”, after 20 boards, on one side.
The ends of this suspended balau ceiling or bulk head needed to tie up with the boards to give it an appearance of being one solid, much wider piece of timber. It is often not possible to use a full-sized timber as it becomes too heavy on the structure, and the pocket. In these instances “build ups” are used to make it look like one solid wider piece of timber. The same principle is common in table tops where the top is only 22mm thick but is built up on the edges to give it the appearance of being 40mm thick. Care must be taken to do it neatly and it must be planned properly so that each piece fits into each other. There’s nothing more frustrating than getting to the end only to find you are 20mm out and should have set your first piece 20mm closer in.
Screw holes were filled with a clear epoxy mixed with saw dust and sanded flat.
This balau ceiling was left un-oiled to give it as much of a natural appearance as possible. It can be finished with an oil and the only product to use here is either Timberlife Satin Wood 28 Base or Woodoc Deck Dressing. This oil soaks into the timber. Most other products will dry on the surface and will eventually peel and flake.
