Since the process of cupping is the wood reacting to moisture, if the wood ’s moisture level returns to the proper equilibrium, the cupping can resolve.

Depending on the type of moisture issue, however, will determine how easily it can be fixed or how much effort it will take. While wood floor cupping is a slower process from water vapor, taking weeks or months, the are the same.

It refers to a state when the individual wood planks appear to be higher on the edges as compared to the center of the boar forming the shape of a cup. Cupping is a result of the changes in moisture in the room. When the moisture increases, the wood swells and then when it decreases, the wood shrinks.

How to Fix Cupped Hardwood Flooring. The planks that make up wood flooring expand and contract based on the amount of moisture in the room. Whenever there is too much moisture, the wood expands. A crowned wood floor is another problem that is usually the result of a moisture issue.

Crowning is typically a problem that is a direct result of cupping. Like cupping , wood floor crowning happens because the boards are exposed to a moisture imbalance over an extended period of time. Ultimately boards that have cupped due to these moisture differences develop a set and remain cupped even when the boards have dried. You can observe this dramatically in an interior wood floor that has been floode then dried.

First round of flooring cupped. Boards will remain cupped. Floor replaced with same type flooring using special moisture resistant adhesive. Slab passed moisture reading required for gluing flooring. Second floor also failing with cupping over of floor.

Now scheduled for third round of flooring. Different type of engineered hard wood , same moisture resistant adhesive. If your hardwood floors have a wavy appearance, they are likely cupping due to wet mopping or an underlying moisture problem.

Convex and Concave Cupping. In wood flooring usually the bottom of the floor is the area where elevated moisture content occurs compared to the flooring surface. Underside of the board absorbs water vapour causing fibre to swell. Cupping , also known as wash-boarding, is the milder form of floor damage.

Picture a typical wooden floor plank. For most solid wood floor species, noticeable cupping can be visible after just a few days. Unlike solid hardwood floors, engineered wood floors cup when moisture levels are reduced. Since engineered wood flooring is created using two layers of wood , the face of the boards will begin to cup faster (roughly times faster) than its backer layer.

The time to refinish wood flooring is after it’s flattened as much as it will. If you sand off the cupped edges before it flattens, you could end up with a ‘scalloped’ floor in winter after it dries.
