Should You Sand Cupped Floors Right Away?
No. Sanding a cupped floor before the boards and subfloor are dry flattens the raised edges while the bottoms are still swollen. As the wood finishes drying, the centers end up higher than the edges, a problem called crowning. Wait until moisture readings confirm the floor is dry and settled.
What Happens If You Sand Too Soon
The board is wet underneath, so the edges are raised.
Sanding cuts the raised edges down to flat.
The board keeps drying and shrinks back.
The edges, now thinner, sink below the center.
The floor is crowned and may need sanding again, or new boards.
- When It's Safe to Sand
- The water source is fixed
- Readings on the boards match dry boards elsewhere in the home
- The subfloor is dry too
- The floor has had time to settle after drying
- Who Checks Readiness
The water damage team confirms the floor and subfloor are dry. The flooring contractor checks again before sanding. Moisture testing · Cupped hardwood floors
