The effectiveness of using lime plaster mixture as a finishing layer of exterior walls of buildings

The issues of the influence of the finishing layer on the heat and humidity regime of building enclosing structures are considered using the example of four types of dry building plaster mixtures and three types of enclosing structures. The amount of condensate falling out is analyzed depending on the type of construction and operating time. It is established that the presence of a finishing layer based on a dry building mixture on the outer surface of the enclosing structure contributes to the dis-placement of the zero isotherm. The use of plasters based on Porotherm LP, VerMix SHN50 dry building mixes and based on the proposed lime plaster eliminates the formation of condensation in the thickness of structures made of expanded clay with insulation and bricks with insulation. The expediency of using a dry building mix based on the developed lime composition with polysaccharide additives is formulated
