What is plaster and what is its use?

Gypsum, which is also called plaster, is a type of construction material that is obtained from gypsum found in nature. Gypsum is found in the form of hydrated dicalcium sulfate in sources on the surface of the earth and after crushing and transferred to the furnace in the form of very fine white powders, it is used for construction purposes. Plaster is used for building joinery, and its use is not suitable for load-bearing surfaces. It has its own complexity, so it requires special skills and tricks to use it.

Gypsum is used in various industries, but its common uses are related to the construction industry for masonry, plastering of walls, ceilings and building columns, whitewashing, cleaning and mortaring.
This substance is one of the ingredients It is used to make the aac block in the amount of 1-0.7%.

Fastness and increase in volume are among the prominent features of plaster that have turned this material into a widely used material in the construction industry. The fastness of plaster has made it available only as much as needed. Because before the work is finished and the whole wall is whitewashed, it becomes dry and hard. If the plaster is stuck, it will increase in volume and by filling the holes and pores, it will create a uniform surface.

Gypsum is a fast-setting material, but to slow it down, you can increase the amount of water and knead the resulting mortar. The mortar resulting from this method is called dead plaster or dead plaster. Dead plaster is used for whitewashing walls. Be careful that dead plaster does not lose its elasticity before drying. Mixing with water causes heat and it is about 20 degrees warmer than the desired environment. Therefore, gypsum mortar can be used at low temperatures. The use of gypsum can somehow create sound and thermal insulation, and it has high resistance against fire.

White plaster

This type is used for whitewash in the building as a face, which has a lower price compared to other types of construction plaster.

Ivory Plaster

Due to its very soft and micronized granulation, this item is used in sculpture, making prefabricated plaster parts, and producing glaze paint.

Gypton plaster

It is obtained from the combination of plaster with adhesive additives such as serisham and it is applied in two layers on brick, porous concrete surfaces, cement surfaces (cement block). and the concrete block is executed.

Marble plaster

This item has a high resistance to moisture and is a type of plaster without molecular water, which is mixed with a solution and then re-baked.

Satin plaster

It is used to whiten the final layer of surfaces. To prepare this material, plaster is mixed with additives such as perlite.

Siva plaster

It is used on all kinds of different surfaces, to perform sub-work operations. It can be used for all kinds of oil paints, acrylic coatings, PVC wall coverings, satin polymer plaster and Belka.
