Part Two Hardwood Flooring – Why Cupping Occurs

Why should you care?

You first need to understand what it means when the hardwood flooring begins to cup. The bottom of the board picks up moisture during the water damage which is what causes the cupping.

Increase of moisture content causes cupping so decreasing the moisture content or drying the boards will cause it to lay back down.

If you still have cupping and your readings are saying the floor is dry….you need to recheck your readings. Those boards still has elevated moisture content.

We have gotten to the end of the drying process, the boards have layed down flat, you may think they look so good i don’t even need to re-finish these.

That is incorrect.

Wait for our next quick tip and we will talk about whether hardwood floors need to be refinished after drying.
