Historical Standard: Standard Specification for Adhesive for Acoustical Materials<\/h4>\n
\n

ASTM D1779<\/h4>\n

Scope<\/strong><\/p>\n

1.1 This specification covers an adhesive for bonding prefabricated acoustical materials to the inside walls and ceilings of rooms in buildings. This adhesive is required to maintain a tensile adhesion (bond strength) of not less than 3.45 \u00d7<\/span> 104<\/sup> dynes\/cm2<\/sup> (\u00bd<\/span> lb\/in.2<\/sup>) for a long period of time under the temperature and moisture conditions likely to be encountered and to maintain sufficient plasticity to allow for movement of parts of the building as it ages.<\/p>\n

Note<\/span> 1\u2014Cleanliness of Surface<\/span>The surface to which the acoustical material is applied with the adhesive should be clean, sound, and dry. Surface coatings should be removed if their nature indicates an unsatisfactory installation, so that the adhesive can be applied to the base. When the adhesive is to be applied on a painted surface, test tile should be applied for 48 h to determine suitable adherence of the coating by examination. Acoustical adhesives are not intended to be applied to surfaces that are moist and that have an alkaline reaction, or that may later become moist or alkaline. Such surfaces, as concrete or plaster, should be properly dried and aged before applying the adhesive.<\/p>\n
