Refinish or replace? How to tell what your wood really needs.
A tired-looking floor, stair or run of trim doesn’t always need to go. Often the wood is fine, and it’s only the finish on top that’s worn out.
First, find out what it’s made of
Solid hardwood can usually be sanded and refinished several times over its life. Engineered wood has a real wood layer on top of a plywood-style core; whether it can be sanded depends on how thick that top layer is, which you can sometimes see at an edge, a heat vent or a threshold. Laminate, vinyl and printed wraps only look like wood, so they can’t be sanded at all. The same goes for trim: solid wood trim can be stripped and refinished, while MDF trim with swollen or crumbling edges is usually best replaced.
Then, look at the damage
- Scratches and dullness in the finish only: often a light sand and fresh topcoat is enough.
- Grey, worn traffic paths: the finish has worn through and the bare wood is exposed. Refinish before it gets deeper.
- Dark black or grey stains: usually water that has soaked into the wood. Sanding may not remove them, and individual boards or pieces may need replacing.
- Cupping, soft spots or movement: check for a moisture or structural problem first. Refinishing won’t fix what’s underneath.
A simple test
Put a few drops of water on a high-traffic spot. If it beads up, the finish is still protecting the wood. If it soaks in and darkens the wood within a few minutes, the finish is worn through there and it’s time to refinish.
When it’s a close call, I’ll tell you honestly which way I’d go and why.
