A wide joint latex grout composition is disclosed comprising a thermoplastic film-forming resin latex and particulate mineral filler, the fillers comprising from about 74 to about 88 percent by weight of the grout composition and possessing a wide range of particle sizes, a major proportion of the grout comprising sand. Cracking in joints up to about one inch wide is avoided by the high sand loading, and dilatancy problems expected from such high sand loadings are obviated by closely controlling the particle size distribution of the sand and other inorganic fillers.
