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

摘要

This report describes the component selection studies for the wall - covering system known as System B. System B was developed for the purpose of lead paint hazard abatement. Detailed performance test data, installation test work, projected costs, and action needed to achieve a commercially available system are given. The components of the system consist of (1) J. G. Milligan and Co. 12 - 209 penetrating adhesive, which will strengthen and stabilize weak surfaces by rebonding loose paint and wallpaper to the wall surface; (2) flame - laminated fiberglass mat / low density urethane foam wall covering applied with the foam side of the laminate adhered to the wall surface with the same penetrating adhesive; and (3) a texture paint coating applied to the fiberglass mat surface by means of a hopper gun. The Milligan 12 - 209 penetrating adhesive should be useful not only with this covering system but also with other covering systems for lead - based paint abatement. Part of its effectiveness is due to the strong film it forms over the surface. The foam component of the laminate makes it practical to apply the system over rough or uneven surfaces and achieve a good bond. An alternate covering system, consisting of a cementitious coating or a textured paint coating, was partially developed but was dropped from consideration as an adequate barrier to lead - based paint. Contract information, tables, articles on fibrous glass, and photographs are included. (Author abstract modified).
