Quick determination of water vapor permeability and water vapor resistance of plasters and putties

The existing methods for determining the coefficient of vapor permeability and vapor permeability resistance of plaster and putty materials are characterized by a long time of the experiment.This underlines the need to create a method for accelerated determination of these indicators, taking into account the simplicity of its practical implementation.The paper provides a detailed description of the proposed method, indicating experimental procedures and an algorithm for processing measurement results.The correspondence of the results of the determination of the vapor permeability coefficient by the accelerated method and according to GOST 25898–2020 is shown.
