The possibility of receiving the organo-mineral additive based on polymineral high-montmorillonite clays is considered. It is offered to use nonionic surface-active agents as an organic component. The organo-mineral additive is offered to be used in paints and dry building mortars (DBM) compositionas the structuring, thixotropic and dispersing additive. The DBM composition has been developed, including lime, glass sand, modifying additives and organo-mineral additive. It is shown, that including organo-mineral additive allows to increase coating offset resistance.

The authors established a higher quality of the appearance of coatings based on silicate paint sol in comparison with coatings based on silicate paints. Information is provided on the regularities in the formation of the quality of the appearance of coatings on the basis of silicate paint sol is that the silicate paint sol has a higher value coefficient of the wetting and spreading on the cement substrate in comparison with silicate paint. It was established that when using a paint brush on the cement substrate, there has been some slowing of the rise time of the structure of silicate paint compositions based on polysilicate solutions. A higher value of the adhesion work based on polysilicate solutions were indentified, indicating the strong force of the paint and the cement substrate.
