Causes and prevention of bad mortar cohesion
The fullness of the mortar in the horizontal mortar joints of masonry is lower than 80%; there are blind joints in the vertical joints, especially in the hollow brick walls, there are often more transparent joints, and the dry wall is built with large shrinkage, and the depth of the shrinkage can even reach 20mm The above affects the fullness of the mortar.

Putty for exterior walls must resist wind, sun and sun, so it has high gelatinity, high strength, and a slightly lower environmental index. The comprehensive index of putty in the inner wall is good, and it is hygienic and environmentally friendly. Therefore, the inner wall is not for external use and the outer wall is not for internal use. Putties are usually based on gypsum or cement, so rough surfaces are easier to bond firmly. However, during construction, it is still necessary to brush a layer of interface agent on the base to seal the base and improve the adhesion of the wall, so that the putty can be better bonded to the base.
