Crowning floor due humidty.

The middle of the board is higher than the board s edges. This issue can either come from a moisture issue that is affecting the center of the planks or from sanding a floor that was cupped and still had moisture issues. Crowning is characterized by wood that is raised in the center and dips down on the long edges of the planks. Unfortunately it s also possible to cause crowning in an attempt to fix cupping.

It usually happens after water is left standing on the wood or if the floor s exposed to high humidity over a long span. It most often occurs when a floor has been sanded too soon after cupping. Cupping occurs when the edges of a wood plank become higher than its center. If the floorboards absorb humidity from the air or moisture from the subfloor they can swell and.

In terms of your flooring excessive relative humidity can cause several issues. Crowning is the opposite of cupping. Like cupping and buckling crowning is a defect a wood floor can develop when exposed to moisture. This can occur when the surface of the floor encounters moisture.

Crowning like buckling and peaking occurs when a floorboard is higher in the center than it is on the edges.
