Hello,
after painting with white water-based paint, a drop unfortunately fell unnoticed onto the floor. After wiping it off, a dark stain was visible on the parquet. I tried to remove the stain with my fingernail, but the top layer came off (see pictures).
Does anyone know how this damage can be repaired?
I suspect that the layer was the sealing varnish.
I am now considering roughening the area with sandpaper in an inconspicuous spot and then applying a transparent, matte sealing varnish.
However, the helpful lady at the hardware store thought that a transparent sealing varnish wouldn’t help here because the color underneath the layer is slightly different.
What do you think? Could you please help me?
Thank you in advance and best regards

Hello questioner,
The good news is: the lady at the home improvement store is not correct!
The parquet wood is factory-sealed and should definitely withstand light scraping with a fingernail.
But that is not the issue here.
Your approach is the right one!
Please use fine sandpaper (120 grit) and a small cork block as a backing to avoid creating indentations in the parquet surface.
Then slightly moisten the exposed parquet wood and, after it dries, carefully sand down any raised wood fibers.
The surface protection can certainly be done with a clear varnish. Ideally, use a spray varnish and apply several light coats to avoid visible overlaps later.
Good luck: KlaRa
