Hardwood Floor Maintenance Issues: Cupping
Most people who have been around a wide variety of hardwood floors are familiar with the issue of cupping, though they may not know the technical term for it. Cupping is a way in which some hardwood floors tend to deform over time. When a floor begins to have areas that dip down, or even divots, it is called cupping.
How Cupping Happens
Cupping happens first and foremost because of moisture in the wood. Since wood was once a living substance, it is composed of cells. The wall of a tree cell is made up of cellulose, which is a strong material that easily bonds with water. When cupping happens, it is an indication that the moisture level present in the hardwood planks is on the decrease. This can happen because the wood was produced and stored in an environment that has a lot of humidity and moisture. When that wood is moved to its final destination in an environment with less humidity, the wood will gradually dry out, which can lead to cupping.
Cupping can sometimes become a severe problem, but most of the time it is slight enough not to be noticeable to the naked eye. Scratches on the surface of the wood, however, are usually noticeable and should be dealt with before they become a true eyesore.
