The new wooden staircase (I think oiled oak) was covered in the middle with painter's fleece for 14 days for protection. Today the fleece came off and we were shocked to find that the uncovered edges on the right and left had darkened.
Should or can something be done about it? Will the middle part of the steps darken in 14 days to match again, or will it take longer? Or will I always see the difference?
The stair builder saw the coating when installing the railing and unfortunately didn't say a word about it darkening so quickly.
