Abstract
A method of humidifying a panel of cellulosic material, at least one side of which has a surface through which the panel can absorb water. A liquid humidifying agent is applied to the panel surface which wets the surface of the panel, which is soluble in water, and which reduces the surface tension of the water. Water is also applied to the panel to cause the water to follow the humidifying agent into the panel to increase its moisture content to a desired value.
