- Timber flooring is normally seasoned or kiln dried to an average moisture content of between ten and 15 per cent. However, there are many local factors that will influence that moisture content once the timber is in place.
- Timber takes up or gives off moisture, depending on the temperature and relative humidity. This is why natural shrinkage and expansion takes place as it tries to equalize with it's surroundings.
- Changes in moisture content of timber are most evident during long dry or wet conditions. But you local environment can also have a big influence.
- Concrete needs to be fully cured before your new timber floor can be installed over the top. 4 to 6 months is usually the time needed for a new concrete floor to be fully cured. Before installation of your new timber floor can proceed, a moisture test MUST be done.
- Good ventilation under your floor is important. Not enough cross ventilation or damp soil conditions from poor drainage can cause problems.
- Air conditioning will normally reduce the moisture content of your home and may cause gaps in the floor underneath the vents.
- Windows, large glass areas and skylights can create hothouse conditions with high temperatures and low moisture. These can contribute to board shrinkage. Excessive direct sunlight can cause colour changes to your floor
- Before the timber arrives, make sure you have suitable storage within the house, as it needs to acclimatise to your home conditions.
Ideally, you should always consult your local timber supplier and installer for peace of mind.
