Check that moisture

As we all strive for that perfect job and superior finish it is timely that we remind joiners, builders, owner builders and do-it-your selfers of the need to be aware of what the moisture content of the timber they propose to use is and how that moisture content can effect the end result of their project.
Flooring, lining board, joinery timbers, and weatherboard must comply with the moisture contents outlined in Australian Standard 2796. This can easily be downloaded off the internet but for many will be confusing so ask your timber merchant for their help and advise.

All timber merchants should carry meters that can gauge the moisture content of these timbers thus allowing them to give advice as to the best installation methods. We strongly advise joiners and builders in particular that they too should carry these meters.

Most problems associated with timber movement be it shrinkage, expansion, cupping or warping can be traced back to the moisture content of the timber used and how it has reacted with the environment around it. Once you have established that the moisture content of the timber you are to use complies with the appropriate standards the job has only just begun. You need to then be aware of the environment in which the timber is to be installed. Will it be excessively hot, dry or damp as any of these can dramatically affect the way in which your timber behaves.

Air conditioners, slow combustion fires, large areas of glass, poor ventilation, direct heat from the sun and rising damp are all things we need to be aware of when preparing to use timber in our building projects.

So don't be afraid to ask for advice, it's free and in the long run could save you a packet.
