ABSTRACT:
Resinous coatings of an ethylenically-unsaturated polyester are employed to form masonry blocks and tiles which exhibit resistance to fading and loss of color consistency in exterior applications. Ceramic coated quartz granules and sand particles precoated with an unsaturated organofunctional silane provide depth and softness of color and texture which when combined with a polymerizable polyester resin produce decorative fade resistant articles that also exhibit resistance to staining and moisture. The sand, granule and polyester compositions of the invention can also be formed as cast articles without masonry unit backing.
