Inspection should be done from a standing position with normal lighting. Glare, particularly from large windows, magnifies any irregularity in the floors and should not determine acceptance. When study is required to observe the condition, the condition is not likely acceptable.
A finish similar to that found on fine furniture should not be expected. Trash in the finish, a wavy look along strips, deep swirls, or sander marks, and splotchy areas can be indications of inadequate finishing or cleaning. The quality of the finish can be acceptable and still include some of these problems, but they should not appear over the entire floor.
The perimeter and hard to reach areas (i.e. under radiators, around cabinets and cabinet cut-outs, closets, corners, etc.) are most likely to contain these irregularities.
Again, when inspected from a standing position these irregularities may be present but should not be prominent. One, two, or three irregularities in a floor do not make the floor unacceptable. Depending on the nature of the irregularities a spot repair may also be warranted.
