A cowboy builder is threatening to wreck a lovely new floor.
He had the woodstain/varnish guy booked at the same time as the plumber. The plumber needed to walk across the floor, so the floor guy left a gap in the staining for the plumber to cross, then came back and filled it in later.
This leaves a vile darker "tide-mark" of double-stain at the join. It looks awful. The varnish hasn't gone on yet.
Is there a way to fix this, or at least improve it?
Mant thanks for any advice
