There, raw gypsum is mixed with several additives, including starch, paper pulp and an emulsifier (or thickening agent), then blended with water to form a thick paste. The gypsum paste is spread onto Manila paper in 3/8-inch to 3/4-inch-thick layers. Another sheet of Manila paper is then laid on top.
The experience of many generations has proved many times that gypsum is the best material to realize stucco and ornamental ideas. With a help of gypsum only, you can work out everything, even the smallest details neatly. It is possible because of gypsum features: it expands and penetrates into the smallest dimples of the form's reliefs.

Lath and plaster is a building process used to finish mainly interior dividing walls and ceilings. It consists of narrow strips of wood which are nailed horizontally across the wall studs or ceiling joists and then coated in plaster.The technique derives from an earlier, more primitive, process called wattle and daub.
utilizing the patented UltraSTEEL™1 process. Cold Rolling and UltraSTEEL™ UltraSTEEL™ is a manufacturing process that alters the characteristics of plain steel, providing higher strength capacity at a lighter gauge. The process effectively hardens the steel by working it in strips with two mating rolls, which produce a dimpled surface

Byproduct gypsum is produced when power companies scrub their coal-fired emissions to remove sulfur dioxide. The resulting byproduct is calcium sulfate. National Gypsum can use this solid waste, which would otherwise go to a landfill, to produce wallboard.
Synthetic or "by-product" gypsum from the desulphurization of flue gases at coal-fired power plants is used where sources are available. Currently three manufacturing plants—Carrollton, Kentucky, Moundsville, West ia and Toronto, Ontario—use synthetic gypsum. The total recycled content for these synthetic gypsum plants is 96%.
★ Gypsum is used in making drywalls or plasterboards. Plasterboards are used as the finish for walls and ceilings, and for partitions. ★ Another important use of gypsum is the production of plaster of Paris. Gypsum is heated to about 300 degree Fahrenheit to produce plaster of Paris, which is also known as gypsum plaster.
Feb 09, 2007· The utility identified as a source of end-user production problems will quickly and permanently lose that gypsum market to more reliable sources. Marketing to an Alternative End-User.
To produce plasters or wallboard, gypsum must be partially dehydrated or calcined to produce calcium sulfate hemihydrate (CaSO4½H2O), commonly called stucco. A flow diagram for a typical gypsum process producing both crude and finished gypsum products is shown in Figure 11.16-1. In this process gypsum is crushed, dried, ground, and calcined.
To produce gypsum board, crushed natural gypsum or synthetic gypsum is is heated or calcined to dehydrate the feedstock. Next the calcined gypsum is mixed with water and additives to form a slurry which is fed between continuous layers of recycled paper on a long board machine.
