Three types of moisture conditions may exist which will forewarn of possible moisture problems: 1. Concrete floor moisture - Concrete floors directly in contact with the ground are never completely dry. Also, the moisture content of new concrete is high, regardless of grade levels. Resilient floors may be seriously affected when installed directly [..]

This procedure involves the removal of fine dust, grit and spills from the floor surface with a mop dampened with a neutral detergent solution. Performed daily, this procedure helps to control grit and can reduce time and money spent on more intensive maintenance procedures.

Most dependent on the porosity of the surface that provides voids for dirt entrapment, presence of surface coatings, uniform coverage of the coating, and toughness of the surface coating to stand-up to wear and maintenance routines.

An "air" space around the perimeter of a laminate floor structure which allows for growth and expansion of the floor due to changes in environmental conditions.

The junction of precut surfaces butted together, such as tile or underlayment boards.

A suspended floor located above the surface of the ground, over a well-ventilated air space with at least 18 inches between the bottom of the lowest horizontal structural member and any point of the ground. An above-grade subfloor is normally over a basement or a crawl space.

Resistance to a form of wear in which a gradual removal of a flooring surface is caused by the frictional action of relatively fine particles. Abrasion resistance generally depends on the toughness of the product or wear-layer, thickness of wear-layer, and existence of surface coatings.

Wearing, grinding, or rubbing away by friction

The act of allowing wood moisture content to become at equilibrium with the environment in which it will perform (See EMC, Equilibrium Moisture Content)
