A scratched timber floor at handover is one of the most common and most argued-over defects. The question that decides the cost is not how deep the scratch looks – it is whether it has gone through the surface finish into the timber. Everything follows from that, and it can be answered in a minute.
The test
Run a fingernail across the scratch. If it does not catch, the damage is almost certainly in the finish and can usually be polished or re-coated. If it catches, it has gone into the timber and no amount of polishing will hide it, because the timber underneath is a different colour. That is the whole triage.
What can be fixed in place
Surface scuffs and light scratches in a lacquered or oiled floor respond to a maintenance product: a refresher for oiled floors, a polish for lacquered ones. On a small area, a local re-coat can work if the floor has a compatible system – and it needs checking with whoever supplied the floor, because some finishes cannot be re-coated locally.
What needs a full re-sand
Anything through the finish, and anything widespread. A patch repair on a timber floor does not match: the new finish has a different sheen and the surrounding floor has aged. Once the decision is that several boards need attention, the whole room usually needs sanding and refinishing, and the cost goes up by an order of magnitude.
Engineered boards have a limit
An engineered board can only be sanded a limited number of times before the wear layer is gone. A 3 mm wear layer might take two sandings in its life; a 6 mm one more. A floor that has already been sanded once may not survive a second full repair, which makes prevention on site worth a great deal more than the repair option suggests.
Prevention is the only cheap answer
The comparison is stark: a fibrous-faced cover costs a few pounds per square metre, and a re-sand costs tens. Any floor that is going to be walked on during the works and is going to be judged at handover should have been covered with something that holds grit. That is the argument, and it is much easier to make before the floor is damaged than after.
What a refinish actually involves
A full sand and refinish means emptying the room, sanding to bare timber, applying a system and waiting for it to cure before anything goes back. On an occupied building that is days of disruption rather than hours. Knowing the real scope is what makes the prevention conversation easy, and it is worth explaining to whoever is deciding whether to buy the cover.
Insurance and who pays
Timber floor repairs are usually the largest single floor claim on a fit-out, and they turn on whether the floor was protected and by whom. Records help: what was laid, when, and by whom, plus the photographs. Where the protection was specified and laid properly, the conversation is short; where it was not, it is long.
Partial repairs that do work
A single damaged board can sometimes be lifted and replaced if the floor is floated and there is spare material from the original delivery. That is the one genuinely cheap repair available, and it depends entirely on someone having kept a few boards back. Worth asking for at installation.
A felt-faced PP honeycomb panel under the works costs a small fraction of the refinish, and it is the grit-holding face that does the work. Corrugated PP sheet alone does not hold grit and would not have prevented this.
What we can do
We supply felt-faced honeycomb protection for timber, and we will say honestly that it is far cheaper than the repair. Tell us the floor type and the wear layer thickness, and we will recommend a cover that keeps grit off it. Contact behaviour with resilient finishes is discussed in scuff marks on vinyl and linoleum.
