Abstract

Abstract A mastic paint composition for concrete is prepared by adding to a mixture of Portland cement with aggregates the following: calcium chloride, naphthalene sulfonic acid formalin condensate, alkyl cellulose, propylene glycol and known additives, such as calcium sulfoaluminate as an antishrinking agent, zeolite as an efflorescence preventing agent, calcium stearate as a waterproofing agent and tributyl phosphate as a defoaming agent as well as coloring agents. A rubber latex or an emulsion of a vinyl resin may also be added. This paint comprosition is made by kneading these components with addition of water into a paste. In applying this paste to a concrete base, there is no need of treating the surface of the base beforehand, but the paste can be applied with a porous hand-roller directly to the untreated concrete base, and a mastic finish can be obtained in one shot.
