Build up your fresco plastering skills at the minimum cost!
To gain experience in plastering at a minimal cost it is possible to prepare a “Practice Lime Putty” from common Type-S Hydrated Construction Lime.
Type-S Hydrated Lime is manufactured from Dolomitic Limestone (Dolomitic limestone contains 35 to 46 percent magnesium carbonate).
Being a great lime to practice fresco plaster application techniques, this lime is NOT suitable for the actual painting in fresco due to high content of magnesium which leads to fast setting, poor adhesion/binding of colors and efforescence on the color layer. However, it is widely used in construction (for which it was developed and manufactured: Type-S stands for “Special”) and is available at very low cost almost at any building supplies retailer.
