US Heritage Group’s handmade Traditional Limewash is a breathable shelter coat that is ideal for historic masonry that requires a vapor permeable finish. Water is the vehicle for limewash; the viscosity is slightly thicker than that of water, causing it to absorb into material in the same fashion as a stain. As the water is absorbed into the substrate and evaporates, the lime is deposited on the surface to color and protect. Lime wash can be applied to any material that is capable of absorbing water, such as brick, wood, stone, plaster, and concrete. This quality prevents it from being applied to materials that have been previously sealed or waterproofed. The combination of a “breathable” stucco or plaster finish, and limewash coating is most appropriate for historic masonry or the construction of a new home, made to look traditional. When ordering, we suggest that you first purchase a small one-quart sample of your preferred color, the white wash base coat, and apply it to the substrate. Please follow the application instructions. Please make your decision 24 hours after the material has been applied to the wall, which gives the limewash sufficient time to cure. Limewash can be applied to a variety of surfaces including brick, stone, plaster, and even wood. U.S. Heritage Group can also provide traditional lime stucco or plaster to suit your project requirements.
