USG_Plaster Mixing Procedures
Successful mixing of industrial plasters requires specific standards and procedures. Recent improvements in plaster formulations have resulted in improved products. To obtain the full benefit of improved products, as well as new products, shop procedures must be standardized. An ideal plaster mix is one in which the plaster particles are completely dispersed in the water to produce a uniform, homogenous slurry. In order to accomplish this goal, batch size, mixer design, mixing time, water purity and temperature must be controlled. This technical bulletin outlines the factors that determine production of an ideal plaster mix.
