Traditional Lime Plaster Techniques

Venetian Plaster

• Venetian plaster is a technique using lime-based plaster with a color additive mixed in. Apply the plaster to the wall in thin layers using a trowel; hold the trowel at different angles for each layer. This change in angles changes the way the color of the plaster appears, creating a rich depth and texture to the wall.

Stucco

• Stucco is among the more recognized techniques of using lime plaster. Common on exteriors, this material is also becoming more widely used as an interior treatment as of 2011. To create stucco, trowel plaster into circular or crescent shapes across the surface. You can achieve this lime plaster technique with pre-colored plaster or paint it after you've applied it and it has dried thoroughly. The time it takes stucco to dry depends on humidity levels, ambient temperatures and the thickness of the plaster. Wait a minimum of 24 hours before painting stucco.

Tadelakt

• Tadelakt is a traditional Moroccan lime plaster technique. This three-layer process requires you to pay special attention to the second layer. Apply the first coat in a slightly waving pattern, some of which will remain visible Then apply the second layer and smooth it as much as possible. Any imperfections in the plastering will remain visible in the final wall. Once you have applied the second coat and it begins to dull, smooth it with a dampened sponge float and apply the final layer. When the third layer is not quite dry, polish the wall with a small stone to create the finished texture of Tadelakt.

Spatolato

• "Spatolato" is an Italian term given to this lime plaster technique because of its final appearance; the word translates to "spatula." Apply the plaster in multiple thin layers using a crosshatch motion. Make thin, overlapping short strokes from various directions to create the distinctive Spatolato finish.
