Abstract

Building materials include a dampening layer which contains a plaster, and hollow microspheres, such as polymeric microspheres. Methods of making a sound dampening material include providing a plaster mixture. The mixture may include hollow microspheres. The plaster mixture is combined with water to form a slurry. The slurry is applied to a surface so that it sets to form a sound dampening layer. Methods of dampening sound through a structure include disposing a dampening layer on a surface of or within a wall, door, floor, ceiling, roof, or floor/ceiling assembly.
