The practical difference
| Question | Screen and recoat | Full refinish |
|---|---|---|
| Does it reach bare wood? | No; the existing finish is cleaned and abraded | Yes; the old finish and stain are removed |
| Can it change stain color? | No | Yes, within the behavior of the wood |
| Best candidate | Intact finish with dullness or light surface wear | Exposed wood, deeper scratches, discoloration, or unwanted color |
| Repairs | Limited; repairs may remain visually different | Board repairs can be blended into the larger sanding process |
| Disruption | Usually lower | More sanding, coats, and cure planning |
A recoat needs a bondable surface
The existing coating must be sound, clean, and compatible with the new coat. Oils, waxes, silicone-containing cleaners, acrylic polishes, and consumer ‘rejuvenator’ products can interfere with adhesion. A test area or deeper cleaning may be appropriate when the maintenance history is uncertain.
Good reasons to recoat sooner
- The sheen has dulled but bare wood is not exposed
- Light scratches appear to be in the finish
- You want to renew protection without changing color
- The floor’s maintenance history and finish compatibility are known
Signals that a recoat is too little
- Gray or raw wood is exposed
- Scratches or dents extend into the wood
- Pet stains or water damage need to be addressed
- The stain color needs to change
- The finish is peeling, contaminated, or failing
The question that protects your money
Ask what happens if the floor fails the compatibility or adhesion evaluation. A responsible proposal should not sell a maintenance coat as a cosmetic reset for damage it cannot reach.
