DULUX AcraTex Sponge Fine Render delivers the charm of yester-year with the benefits of today’s technology and unlike limewash or cement based coatings, will not develop surface cracks. The cured coating has a mottled aged rendered patina and is similar to that of a limewash finish. Specified in multilayer applications, generally without topcoat, the natural finish will age gracefully. Can be overcoated with AcraShield Advance weather-proofing barrier topcoat for optimum weatherability.
