Wood is prone to environmental changes such as temperature, moisture, winds, etc.
Due to environmental changes wood tends to crack, decay, warp and damage.
Also due to said changes wood tends to decrease its dimensional stability and strength.
This happens because wood is attempting to match the environmental changes.
As this is a natural process, wood splitting, warping, cracking cannot be totally prevented.
However, this process can be slow down by applying wood stabilisers.
Wood cracking
Splits and cracks occur when wood shrinks as it dries. Wood shrinks roughly twice as much along the growth rings as it does across the rings and it is this uneven shrinkage that causes cracks to develop.
Splits and cracks in wood are ruptures or separations in the grain of the wood which reduce the quality as measured by appearance, strength, or utility.
Why Wood warps
There’s a gain or loss of moisture content
Dimensional stability
It is the extent to which a given material resists changes in dimension with variations in environmental factors. Wood, however, although little affected by changes in temperature, changes considerably in volume (shrinks and swells) with variations in moisture content. Wood if green or dry is soaked in wood stabilisers for an appropriate period then wood does not shrink appreciably when dried. Equally important, wood thus treated and then dried swells very little when exposed again to high humidity.
Wood stabilisation
Wood stabilization is a system of impregnating wood with chemicals to form a hard and tough surface. Stabilized wood is generally easier to turn, sand, and polish than unstabilized wood, particularly spalted and punky woods. Stabilizing enhances grain appearance, increases water-resistance, and the increased hardness helps resist scuffing and scratching.
Wood products change and warp depending upon the temperature and humidity. If you want to reduce the chances of this happening, you can stabilize the wood with chemical treatments. Doing this will add weight and harden.
