Cement plaster. Advantages and disadvantages of cement plaster. Cement plaster is a time-tested building material. In recent years, fewer and fewer cement mortars have been used, many construction companies are more likely to choose Group II solutions. In addition, the energy saving rule forces this trend, but it imposes higher construction physical and technical requirements, which can be more easily achieved by light and thermal insulation cleaning. The main components of cement plaster include binder cement, as well as partial lime, rock grain and possibly other additives and additives depending on the manufacturer. Cement plasters are very resistant to pressure and moisture-resistant in nature. The surface of the plaster is very hard and stable, but the stresses in the masonry can be mitigated worse, so this can lead to cracking or peeling faster. Cement plaster is suitable, in particular, for the exterior plaster of basement walls, plinths and surfaces that must withstand heavy mechanical loads.
