Painting on dry plaster is a technique used in art and architecture. The two most common types of painting on dry plaster are secco (5 letters) and FRESCO (6 letters). Secco is a painting technique where the artist paints onto dry plaster with water-based paint. FRESCO is a painting technique where the artist paints onto wet plaster with water-based paint. Both techniques are used to create beautiful works of art and architecture.
