Abstract
A feldspar containing protective composition for paving, coating, sealing and the like includes a dry component mixed with a liquid component in an amount necessary to produce a desired consistency of the composition. The dry component includes about 40-50% by weight of feldspar aggregate, about 35-40% by weight of a mineral powder, such as a pottery grade feldspar, up to about 15% by weight of masonry mortar and up to about 7% by weight of cement. The total amount of masonry mortar and cement is at least about 10% by weight of the dry component. The liquid component is formed of an adhesive copolymer in an aqueous emulsion, such as ethylene vinyl acetate.
