Commercial flooring generally performs best when it is installed over a clean, sound, smooth, and sufficiently flat substrate. High spots and low spots can telegraph through resilient flooring, create visible irregularities, reduce adhesive contact, and cause problems at seams or transitions. Uneven floors may also interfere with carts, rolling chairs, shelving, partitions, or equipment. Substrate correction can include grinding high areas, filling depressions, patching damaged concrete, or using an approved leveling material. The required preparation depends on the flooring product, installation method, substrate condition, and project specifications. Floor preparation should be evaluated before the installation schedule is finalized. Substrate correction may affect labor, material quantities, drying time, and the date on which flooring installation can begin.
