Mel powder is a creamy white powder obtained by crushing calcium carbonate rock. Mel powder, which is also known as putty powder, has very fine grains and is completely smooth and uniform. Mel powder's stickiness is high and it becomes very resistant after drying and losing moisture. Mel powder is used in building painting, for the production of chemical varnishes, in perfumery, in rubber production, in the production of toothpaste and sculpture. Mel powder is also known by other names such as putty soil, putty mud, and caulking powder. Mel soil is the main ingredient of putty or putty paste, which is also known as putty mud. Also, among other uses of powder flour, we can mention its use in bonding and filling the space between tiles and mosaics of wall or floor surfaces and building paint. Powder is the most basic material used in patina work and it is also used to create a prominent texture on the wall. Mulch has a fine granularity and is mainly classified in the group of building painting materials. Mel powder is light and compact and easily dissolves in various solvents. The adhesiveness of this type of powder is high and increases after drying and losing moisture.
One of the important uses of Mel powder is to make oil-based putty, to make relief panels, and to repair various plaster and wooden surfaces. Cited.
The importance of using Mel powder
Mel putty powder alone is not useful. By adding different ingredients, this powder becomes a soft and homogeneous paste, when this paste is placed on the cracks, fractures and grooves of the work surfaces, it fills them and becomes strong after drying. Mel powder quality depends on the concentration of calcium and its impurities. Mel powder is also used in building painting as a sealant and filler for the unevenness of the work surfaces.

Advantages of using Mel powder in building painting
When we talk about putty in building painting, it means a substance that is created by combining Mel powder with several other substances, the obtained combination is called putty, which has different types. Putty is very similar to gypsum powder, for this reason it molds to the shape of the materials around it and becomes very hard after drying.
The putty paste obtained from the combination of Mel powder, due to its high flexibility and strength, is used in making sculptures. And relief panels, which are made of stone powder, are also used. Among the other uses of Mel powder, we can mention patina on wood and glass, use in the production of resin and varnish. Mel powder is one of the most basic materials used in patina; Mel powder is also used together with glue and oil to prepare sculpting paste.
