Abstract: The present invention is directed to a trowelable, lightweight, synthetic stucco composition containing a crushable, lightweight aggregate, and specifically to the protection of the lightweight aggregate from substantial particle size reduction during troweling application by providing in the composition a protective amount of a hard, non-crushable aggregate having a protective particle size. The hard aggregate is strong enough to resist the troweling step without crushing, and serves to keep the trowel a spaced distance away from the substrate upon which the stucco composition is applied, to thereby substantially prevent crushable, lightweight aggregates of similar or smaller particle size from crushing, and to limit the crushing of crushable, lightweight aggregates having a larger particle size.
