Technological processes of plastering various surfaces and structures with simple, improved and high-quality plasters
GENERAL DATA 1.1 The technological map has been developed for the installation of simple, improved and high-quality plaster coatings of internal brick surfaces of walls and partitions up to 3.5 meters high (hereinafter referred to as plastering works) using lime-cement mortars in a mechanized way. 1.2 Plaster is a finishing layer on the surfaces of various structures of buildings and structures (walls, partitions, ceilings, columns), which aligns these surfaces, gives them a certain shape, protects structures from moisture, weathering, fire, increases heat transfer resistance, reduces air permeability and sound conductivity of enclosing structures. 1.3 According to their purpose and properties, monolithic plasters are divided into ordinary ones - intended for use in normal temperature and humidity conditions, special ones - performing protective functions in relation to the base, and decorative ones - for finishing facades and some rooms of public buildings (lobbies, halls, stairwells). 1.4 Conventional plasters, depending on the thoroughness of execution, are divided into three categories: simple, improved and high-quality, which are shown in Figure 1. а - простая; б - улучшенная; в - высококачественная; 1 - основание; 2 - обрызг; 3 - грунт; 4 - накрывка Рисунок 1 - Виды штукатурки
