crp July 31, 1962 MORE ABOUT AUDICOTE "May Audicote be applied to bases such aa Baxbord, Sheetrock, or previously painted surfaces7" Our formal recommendation, and the only one for which, we are responsible, is contained in the AIA folder... "may be applied to properly prepared gypsum or Portland cement lime basecoata, or over monolithic concrete." While we realize that Audicote has been and will continue to be used on other than recommended bases, with varying degrees of success, those adaptations are at the user's own risk. "May Audicote be used as a simulated acoustic?" The nature of the material, and the thin consistency required for spray application, renders it unsatisfactory for this purpose in either hiding power or finished appearance. We know of no case where it has been used successfully in this manner. "Is two coat application always recommended?" Ho. We have come to recognize, as have most manufacturers of acoustical plasters, that on low suction baseB, three coat application may be necessary. The first coat provides suction for succeeding coats, and reduces tend ency for blistering and drop-outs on low suction bases such aa mono lithic concrete. Our bag directions are being revised to show this (a recommendation also made by other manufacturers) when existing bag stocks are depleted. It is part of our responsibility as effective, product-wise salesmen to be acquainted with performance characteristics of Audicote... to discuss the -sensible limitations of the product (as well as its advantages) so that we are not placed In a position of liability beyond the intended, specified use of the product.
