What are the common problems in plastering interior walls?

When plastering the interior wall, it is sometimes found that the plastering layer is not firmly bonded with the matrix, which leads to problems such as hollowing and cracks. This is mainly due to insufficient cleaning and wetting of the base, and uneven shrinkage stress is generated during the hardening process of mortar strength growth, thus forming the phenomenon of drying shrinkage cracks.
2. The plastering layer is too thick
The plastering layer will be too thick during construction. At this time, the plastering layer can be cracked, and the thickness of the plastering layer can be controlled within a certain range, and kept at about 20 mm During operation, it should be plastered intermittently by layers, and the plastering can be carried out for the second time after the first time of ash solidification. Never do it all at once.
