What are some ways to prevent board cracking?

Wooden boards are extremely sensitive to moisture content; exceeding the specified range can easily lead to cracking or warping, rendering them unusable. This can cause significant losses for large manufacturers. Given this, what methods can be used to prevent board cracking? And in what areas should we pay extra attention?

First, mechanical protection method

Those who frequently handle these kinds of things know this method: after the board is dried, to prevent it from deforming or cracking, they tie some wires or something similar to it to fix it. This applies a force from the outside, which can better control the expansion of the board. After using this method, the degree of cracking will naturally be much smaller.

Second, brush some paint on the surface.

The reason wood cracks is simple: it contains too little moisture, just like how steamed buns will crack if they're too dry. To avoid this, we need to retain its internal moisture and slow down evaporation. How can we do this? There's a type of coating on the market that, when applied to the surface, reduces moisture loss and is very effective in preventing wood from cracking.

Third, the immersion method using specific reagents.

There are many products on the market to prevent wood from cracking. One type of waterproofing agent is particularly effective. Simply soak the product in it, and after a long period of treatment, it will completely penetrate into the interior of each grain. This way, when the product is taken out, the moisture will no longer easily evaporate and can be maintained within the specified range for a long time.
