I was out of town for 5 days and during that time my kitchen faucet spontaneously developed a slow leak. Upon returning home there was a 7 foot by 7 foot puddle of water in the kitchen -- probably sat there for at least a few days. Some of that water also went underneath cabinets. The kitchen has oak hardwood floors (solid oak, non-engineered, narrow 2" tongue and groove planks). Some of the planks have begun to "cup" (curl upward along the edges).
I've read that it's possible the wood may lay flat again if it's thoroughly dried out. I've also read that mold is a risk if it's not dried out properly.
Here's what I'm currently doing to dry out the floor:
- Closed off the kitchen and raised the temperature to ~83 degrees Fahrenheit using an oscillating space heater.
- Oscillating fans blowing across the surface of the floor.
- Oscillating fans in the unfinished basement blowing air at the subfloor.
- Dehumidifier running non-stop in the kitchen (30% humidity, as low as it will go).
I've been taking moisture readings with a pinless sensor, but the drying doesn't seem to be making much progress. The surface obviously feels bone dry to the touch, but on the seams where the oak planks come together the moisture sensor gives an off-the-chart reading (over 30% moisture content).
Does anyone have any other ideas for drying out the floor quickly?
I did stumble across this "rescue mat" system: https://www.jondon.com/dri-eaz-rescue-mat-system.html which appears to suck water from the floor, but the accompanying Dri-Eaz vacuum costs over $2000 (!!!). Perhaps I could connect those rescue mats to a regular shop vac and get the same effect?
Any tips much appreciated! Would love to hear if someone has managed to salvage "cupped" wood floors without having to sand and refinish them.
UPDATE: It's been one month since I posted this and I have had the oscillating space heater, fans and a dehumidifier running non-stop the entire time -- maintaining 84 degrees in the kitchen. The moisture content of the wood has come way down, but it's still elevated -- 9.3% in some spots. The cupping has flattened out a lot and I have a feeling it will completely disappear given another month or two.
