Description:
Western 1-Kote Premium 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 Premium Sanded Gray is a cement plaster that only requires water at the jobsite. Western 1-Kote Premium 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.

​

Western 1-Kote Premium Sanded Gray features a low shrinkage formulation, enhanced fiber content and accelerated set characteristics designed to improve crack resistance and finish readiness while maintaining the consistency and control of a factory sanded 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 Premium Sanded Gray is also available in a pump-grade version with an excellent flow that does not require additional additives (Hi-Flow).
