Production of gypsum stucco - a rather complicated process, from a technological point of view. He performed in several major phases. First element model of the future is made of molding. At the same time apply the soft pliable material such as clay and clay that can easily take the desired shape and hold it. Then the molding, allowing us to obtain accurate terrain model of the future. At this stage it is important to first verify the absence of possible defects, since otherwise the model will be inaccurate. At the last stage finished form is filled with plaster.
Production of gypsum - a process of thermal treatment of natural gypsum. His burnt, and then the stone ground into a powder and as a function of grinding gypsum are divided into groups: coarse, medium and fine grinding.

Building plaster divided in terms of its setting.
A - a quick-cast (initial set 2 minutes, the end - at least 15 minutes)
B - normal-setting (6 minutes initial set, the end - at least 30 minutes)
In the - slow-setting (initial set no earlier than 20 minutes, final set is not specified)
D - Durability is determined by the 12 brands of gypsum in compression.
They are: G-2, G-3, G-4, G-5, F-6, G-7, G-10, F-13, F-16, F-19, F-22 and F-25. Where number is the limit of compressive strength - 1 MPa (10kg/sm2)
In other words, for example gypsum g-16 - its strength is 16 MPa

For stucco work used mainly gypsum grades G-5 - G-10.

Gypsum - a binder, which expands and heats up during solidification. In the expansion of gypsum stucco work is a positive feature, since it will penetrate into the smallest form of relief.
