Description:
Western 1-Kote Sanded Gray is designed to be a cost-effective, factory premixed, fiber reinforced, modified portland cement exterior plaster for one coat wall systems. Western 1-Kote Sanded Gray is a cement plaster that only requires water at the jobsite. Western 1-Kote Sanded Gray may also be used over wood or gypsum backing and may be utilized for a scratch and / or brown coat application for a conventional stucco system.  It is available in a “regular” as well as a “premium” blend.

 

The base coat is designed to be mixed with a fixed quantity of water (unlike traditional one coat products where the water varies due to the moisture content of the bulk sand.) By eliminating the variables of field mixing - every bag, every batch and every wall - are produced with consistent performance characteristics.  Western 1-Kote Sanded Gray is also available in a pump-grade version with an excellent flow that does not require additional additives (Hi-Flow).
