Western 1-Kote Premium Sanded is designed to be an upgraded product for one coat wall systems. Western 1-Kote Premium Sanded is a cement plaster that only requires water at the jobsite.

This product is currently manufactured in different regions and attributes may vary. Check with your supplier for more information.  

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 the best quality available in the industry.
