Q: Is is better to have 2 or 3 coats of polyurethane when refinishing hardwood floors?
A: I use 3 coats as a standard finish on all jobs. 2 coats is more like a “clean up” job. The more important factor is that oil based finishes be used without cheap, fast dry sealers as a base. The straight application of polyurethane, buffed between each coat is a far more durable product.
