A coating composition is provided comprising hard particles, a binder and at least one thickener. Pigment materials, dispersants, biocides and antifoaming agents may also be included. The particles may be about 0.001 to about 0.02 mm (about 1.0 to about 20.0 microns) in size and have a hardness on the Mohs hardness scale of at least 5. The hard particles may be present in the composition in an amount of about 2.0 to about 15.0% by weight of the composition. The coating composition can be applied to the veil to form an abrasion resistant coating. The coated veil can then be used to form a coated gypsum product. The coating composition improves wear resistance and reduces the damage that may be caused by rolling and handling of the coated gypsum product during installation and / or adverse conditions after installation. Also provided are methods of forming coated veils and coated gypsum products. |
