Hardwood floor refinished?

hard wood floor refinishing Add comments

Refinished my hardwood floor and replaced the water based to oil based finish. Now I am having a cupping problem. Please help

Cupping of hardwoods means one thing and one thing only….too much moisture.

Is your home on a crawl space or on a slab?

If on a crawl space….is there visqueen under each and every inch of your floors? Were the windows closed or open upon refinishing? Was there enough time allowed with the oil based finish between one coat and the next? Is your ice maker leaking only when it is on and running under the floor? Is there a toilet running and leaking that you really haven’t noticed?
Where is the water coming from???? Did you have a dehumidifier running and turned it off? Where is the cupping the worst, that will likely be close to the origin of the issue.

While hardwood floors will last forever,they can be terribly finicky about the conditions they are in.

Call the installer or flooring company back immediately!!! Also, call a plumber to make sure that this is not a plumbling issue. A plumber can check for leaks in pipes below ground level to see it that is the issue. If that is the case, once the leak is repaired…put some fans on the floor, and it will settle down.

Although you just had the floors redone….sometimes issues are just a weird matter of circumstance.

    The cupping isn’t likely related to the finish, but rather water intrusion. The finish wouldn’t cause cupping. Maybe a strange pattern or an uneven look, but cupping is highly unlikely.

    I would suggest getting a moisture meter (see if you can’ rent one, they are expensive >$100) and testing the wood (try along the base to keep the prong marks to a minimum. See what the readings reflect. I’d bet you have a minor water leak, maybe slab or something wicking in from an adjoining lav?

    I would start running fans aimed at the floor right now. Once you find and fix the leak, place several fans over the cupped areas and leave them running. This may take several weeks. I once had a lady whose saltwater aquarium broke while she was on vacation and the water sat on her floor for almost two weeks.

    She ran fans for almost a month and we had very little in the way of sanding to do to get the cupping reduced to nothing.

    movement in hardwood floors is usually because of moisture. it can come from a small water leak or could be from a change of season. cupping is a sign of to much moisture.you can try a dehumidifier. you will have to find the setting that keeps your floor flat by bringing the moisture down a little at a time. going to far will develop cracks. good luck.
