Development of Lead Based Paint Hazard Abatement System Using Laminated Wall Covering and Adhesive Systems. System A

摘要

This report describes the component selection studies for the wall - covering system, known as System A, that was developed for lead - paint hazard abatement. Detailed performance test data, installation test work, projected costs, and action needed to achieve a commercially available System A are given. The components of the system are a wall covering consisting of a factory - laminated, coated wallpaper and fiberglass mat. A barrier adhesive saturates the fiberglass mat and provides the bond to the wall surface. A strippable feature is built into the system to provide further lead - paint hazard protection. When numerous combinations of wall coverings and fiber glass mat were evaluated, the most promising combination was a polyethylene - coated, 59 - pound - per - ream, bleached kraft paper laminated to a 1.4 - pound - per - 100 - square - foot fiber glass mat. The most acceptable barrier adhesive found when considering system performance, application methods, and environmental conditions was the J. G. Milligan and Co. 12 - 225 barrier adhesive. The system, as designed with these components, has the desired strippability feature and provides a good barrier to lead - based paint. Contract information and company correspondence are appended; an article on fibrous glass and tables also appears. (Author abstract modified).
