You can put some desiccant or mothballs to keep the wood dry and absorb excess water.

The texture of the wooden blackboard is generally larger, so if you want to wipe it clean, you must ensure that the surface of the blackboard must have the friction needed for writing, and at the same time, the friction should not be too large.

In general, we use ink mixed with the juice of frozen pears eaten in winter to paint the blackboard surface. This is tried, it works very well, and it lasts for 3 months, so you only need to brush it twice a semester.

Principle: Physics.

At the same time, because the ink particles in the ink are smaller, the surface of the blackboard after painting is relatively uniform, the diffuse reflection is enhanced, and there will be no reflection, and the handwriting will be clear due to the contrast between black and chalk white. The effect of pear juice is that it contains sugars in the middle, so the viscosity is larger, and there are other substances, the first will not attract insects, and the second has no special taste, so it is the first choice. In this way, the ink particles in the ink are relatively firmly adsorbed on the wooden board and can be used for a long time.

The principle is this, if you choose other materials instead of pear juice, you must be careful not to have a strange smell and attract mosquitoes, and I hope you will develop more other methods!
