The processes of development of finishing coatings on the basis of cement colloidal systems are determined. The influence of processes of modification of colloidal cement systems on the properties of decorative coatings is studied. It is shown that the introduction of modifying additives in combination with mechanical activation allows using the optimal technological parameters of processing to give colloidal cement composites the necessary properties and increase the resistance of protective decorative coatings. The joint activation of the components of colloidal cement adhesive with a modifying additive leads to an increase in the strength of the samples at all times of hardening. Studies have shown that modifying additives and fillers have a positive effect on the thixotropic properties of the system and contributes to the formation of the hydrate with colloidale particles, which leads to hardening of the reinforcement system of a composite. Found that the addition of metakaolin enhanced the activity of fine cement systems. Studies have shown that fillers have a positive effect on the thixotropic properties of the system and contributes to the formation of the hydrate with colloidale particles, through which are formed the spatial packing, which leads to hardening of the reinforcement system of a composite.
