Abstract
An alkaline liquid composition is disclosed which is useful for restoring grout. The composition consists essentially of an aqueous dispersion of a film-forming polymeric resin, a compatible surfactant, a basic alkali metal salt, sodium hypochlorite, pigment, and an amount of zinc oxide effective to set the composition when it is coated onto and absorbed by the porous grout.
