Chengdu dry mixed plaster mortarRelated introduction:

Mortar applied on the surface of buildings or building components is collectively referred to as plastering mortar。According to the different functions of plastering mortar, plastering mortar can be divided into ordinary plastering mortar, decorative mortar and plastering mortar with some special functions (such as waterproof mortar, insulation mortar, sound-absorbing mortar and acid-resistant mortar, etc.)。 The plastering mortar is required to have good workability and is easy to be spread into a uniform and flat thin layer, which is convenient for construction。There should also be a high bonding force, and the mortar layer should be able to bond firmly with the bottom surface, and will not crack or fall off for a long time。In a humid environment or vulnerable to external forces (such as the ground and wall skirts, etc.), it should also have high water resistance and strength。

Compared with masonry mortar, plaster mortar has the following characteristics:

① The plaster layer does not bear the load;

(2) The plaster layer and the base layer should have enough bonding strength, so that it does not fall off and crack during construction or under the action of long-term self-weight and environment;

③ The plastering layer is mostly thin layer, and layered coating, the surface layer requires smooth, smooth, meticulous and beautiful;

④ It is mostly used in dry environment and is exposed to air in a large area。

Plastering mortar is usually constructed in two or three layers:

(1) The role of the bottom mortar is to make the mortar and the base can be firmly bonded, and there should be good water retention。

(2) The middle layer is mainly for leveling, and sometimes it can be omitted。

(3) The surface layer is mainly to obtain a smooth and smooth surface effect。
