Imperial Gypsum Base is ideally suited for fire-rated veneer plaster systems. The panels are available in a variety of sizes and large enough to be installed like drywall panels. The distinctive blue face paper is designed to provide the qualities desirable for veneer plaster applications, that is, it provides for a strong plaster bond, controls water absorption and resists plaster slide. The panels provide a rigid base that resists sag and are not affected by decay, normal moisture or dry rot; they will not attract vermin. When securely attached, gypsum base adds lateral stability to the assembly. Also, gypsum base partitions faced with veneer plaster on both sides have high resistance to sound transmission. Resilient attachment further improves ratings.
