Explanation

Adhesive surfaces are surfaces that are wetted by water. This means that the water molecules are attracted to the wood surface, and they spread out to form a thin layer in order to maximize their contact with the surface. The adhesive forces between the water molecules and the wood surface are stronger than the cohesive forces between the water molecules, resulting in a thin layer.

There is an explanation video available below.
