Timber flooring

Shrinkage and expansion of timber floorboards and timber wall panelling is a natural and cyclical process.

The degree of movement depends on the surrounding changes in atmospheric moisture content and therefore is generally controlled by seasonal weather conditions.

Changes are most evident during long periods of either dry or wet conditions.

However, local conditions also have considerable influence.

This Primefact covers the following topics:

• Home design considerations
• Polyurethane finishes
• Acclimatisation of natural timber flooring
