Hardwood Finish Problems
Hardwood floor finish problems — peeling, flaking, bubbling, clouding, and discoloration — are common complaints that can stem from several causes. Finish is the protective layer that shields the wood beneath, and when it fails prematurely, it often signals an underlying issue with moisture, application technique, or product compatibility.
Key Takeaways
- Peeling and flaking often result from applying finish over contaminated wood, excessive moisture, or improper sanding
- Bubbling is typically caused by trapped air or applying finish too thickly
- Clouding or whitening can indicate moisture trapped beneath the finish film
- Discoloration may result from UV exposure, chemical reactions, or incompatible product layers
- A certified inspection evaluates the finish type, application method, wood moisture, and environmental conditions
