How to Apply Marmorino Plaster
Creating a "Marmorino Effect"

The Marmorino Effect surface is smooth with a matte sheen and cloudy variation of values.

Marmorino is a term used to distinguish a traditional Italian plaster formula comprised of lime and fine marble dust. Materials with other additives, like silica sand, do not meet the Italian requirements for Marmorino. By using this traditional formulation or by using other fine grained lime based materials with sand additives a Marmorino Effect can be achieved.

The final effect you wish to achieve will determine the material to use.

Select Finish & Material

Finish Qualities Grain Material
For a matte surface with little modeling Fine Marmorino ks
For a matte surface with light speckling of burnished silica sand Fine/Medium Marmur Fine
For a surface with a variety of grain size and modeling Fine/Medium Marmorino by La Calce Del Brenta

1. Substrate Preparation:

  • Ensure your substrate is smooth, flat and level. This step is one of the most important and often overlooked. Any voids or high areas will cause those blemishes to polish more than the surrounding area.
  • Tape off any trim or adjoining walls not receiving plaster.
  • Prime the wall with preferably an oil based (low odor, quick dry) primer or other approved primer. This step isolates the substrate from the Marmorino finish which will ensure even suction of the finish material across the surface.

2. Base Coat:

3. Finish Coat:

  • Apply first coat of selected material (Marmorino ks or Marmur Fine or Marmorino by La Calce Del Brenta) with a stainless steel trowel using short random strokes. Do not let your edges dry; apply wet material to wet material. Let this layer dry about 70%.
  • Before the previous coat completely dries, apply a second coat of selected material with the stainless steel trowel. Increase your troweling pressure for this coat.
  • Before the material dries completely trowel down the material with a clean and polished Trapezoid Finsh Trowel stainless steel trowel. This step will close up close up grain and smooth the surface.

4. Polishing:

  • After one hour of drying, polish out the surface using a clean stainless steel trowel. Use short random strokes and keep your trowel edge clean. A smaller trowel will provide more pressure for polishing.

5. Wax and Sealing:

  • If increased gloss or water protection is desired apply a Cera Pase Wax.
  • Apply with a clean rag or trowel
  • Buff with a rag or buffing wheel.
