Is there something wrong with this HardWood Floor
I am doing a home renovation and ran into a problem today with a hardwood floor subcontractor.
He was hired to sand brand new walnut hard wood floors. He took about 3 days to complete the job. The problem is that I am seeing like waves and waves of what looks like bumps. I asked him if that was normal, and he mentioned about 90% of the homes turn out this way. The problem is I have never seen any hardwood floors that looks like this. So I asked my General Contractor, his reponse was he doesn't know but he has never seen this either.
So I guess I am here asking if this really is normal for walnut, because honestly I don't know.
Thx for your help.
