Lime Wash:

Composition: Lime Wash is a traditional technique that involves mixing slaked lime with water and pigments. When applied to walls, it imparts a soft, mottled appearance that can range from subtle to vibrant, depending on the desired effect. Lime Wash is breathable, allowing moisture to evaporate and preventing mold and mildew growth. It's an excellent choice for historic homes, as it can recreate the classic look of aged, weathered walls.

Ideal Usage: Lime Wash is perfect for historic restorations, interior and exterior masonry, and drywall applications. It can also be applied over textured surfaces like cement, brick, or stucco.

Application: Lime Wash is applied using brushes and can be applied over texture or exterior surfaces like brick or stucco.


  • Organic and breathable finish.

  • Ideal for creating a weathered patina with subtle movement and natural color variation.


  • Not washable; challenging to touch up.

  • Sealer may affect color, recommended for lighter shades.

Maintenance Tips: Despite the name, Lime Wash is not washable. However, a matte wall sealer is available for added durability.

Roman Clay vs. Venetian Plaster: A Closer Look

Roman Clay vs. Venetian Plaster:

While Roman Clay offers a textured finish with various effects and is ideal for smooth interior walls, Venetian Plaster is a smooth, polished finish. It's a mix of slaked lime, marble dust, and pigment, creating a shiny, marble-like surface. Venetian plaster can be applied to interior and exterior walls using a trowel with multiple thin layers and fluid movement in different directions. Its application is heavyweight and dries with a more stroke-like finish.

Both finishes have their unique appeal and can be chosen based on the desired aesthetic and the surface they will be applied to.
