Finish peeling or flaking off the floor
Also searched as: finish coming off, floor finish flaking, varnish peeling
What it looks like
Sheets or flakes of finish lifting away and leaving bare wood, with a clear edge between coated and uncoated. Distinct from wear, which thins gradually with no lifting edge.
What causes it
In rough order of likelihood. Each one has a tell — the observation that separates it from the others.
A recoat applied over a contaminated surface
How to tell: Peeling within months of a refinish. Residue from an acrylic or oil-soap polish is the usual culprit — nothing bonds to it.
The floor was not abraded before the new coat
How to tell: Peeling in sheets across a wide area on a recently recoated floor. Finish needs mechanical key, not just a clean surface.
Incompatible products stacked on each other
How to tell: An oil-modified coat over a waterborne, or a different manufacturer's system, and it began lifting within the first year.
Moisture pushing up from below
How to tell: Peeling alongside cupping or dark staining. The finish is not the problem here; the water is.
What it actually means
Peeling is an adhesion failure, not a wear problem. Nothing you put on top will stick either, because the layer beneath it is what has failed.
Can it be fixed?
Usually repairableThe failed finish has to come off entirely — every trace — and the floor recoated properly. It is a full sand, not a screen-and-recoat, and pretending otherwise just repeats the failure. The good news is the wood underneath is usually fine.
What you can do yourself
- Stop using any polish, restorer, or 'rejuvenator' product immediately. These cause more of this than anything else.
- Clean with a hardwood-specific cleaner only, and keep bare areas dry.
- Find out what was applied and when — the product and the date change the diagnosis.
- Do not spot-patch. New finish over a failing layer lifts with it.
When to call someone
As soon as bare wood is exposed. Once dirt gets into open grain the sanding gets deeper and more expensive.
