Hi, I have some questions for somebody with a knowledge of hardwood floors finishing. My mom is planning to put water based polyurethane over her old floors that were sanded few years ago. Oil based floor finish was used on them after that sanding. The floors are not in a bad condition. She is not planning to have them sanded this time.
When applying floor finish without sanding is it necessary to put some kind of binder on the floor before putting water based polyurethane over the existing oil based finish?
Could applying this without any sanding be a terrible idea?
Thank you.
