Application information of the method of canonical correlations to assess the influence of technological factors on the quality of paint coat of building products and structures are provided below. The algorithm for calculating the method of canonical correlations is considered. It is shown that the substrate porosity is determinative for the paint coat quality. The viscosity of the paint applied by the pneumatic method affects the quality indicators less, especially compare to brush application. The coefficients in canonical variables characterize the strength of the influence of the relevant signs-factors and the efficiency of indicators on the level of communication between them. Various ways of applying paint are considered on substrate with a porosity of 24%, 28%, 32% on the example of oil paints MA-15, of alkyd paint PF-115, of water dispersion paint AK-111, it is shown, that the porosity of the substrate is a decisive factor in determining the quality of the paint coating. The viscosity of the paint when applied by the pneumatic method affects the quality indicators less compared to the brush application.
