Abstract
In circumstances where flooring may have a high moisture content, for example some types of concrete floors, at least one moisture sealing coating is applied to the floor to substantially preclude moisture migration from the floor, and then a first adhesive is applied over the moisture sealing coating and a scrim is applied to the first adhesive and held in place by the first adhesive. The scrim may be a layer of non-woven material that provides a surface substantially impervious to moisture. A second, carpet installation, adhesive is applied over the scrim, and commercial carpeting is laid on the second adhesive. Usually the scrim and carpeting will have seams, and the carpet installation is practiced so that the seams of the carpeting are substantially perpendicular to, or spaced at least about 6 inches from, the scrim seams. When worn the carpeting, scrim, and adhesive layers can be taken up, and the method repeated. Where a calcium chloride test of the flooring indicates a moisture reading less than 3 pounds per 1000 sq. ft. for 24 hours, the moisture sealing coating need not be applied.
