Тhe physic-mechanical properties of the compositions based on inorganic polymer – so-dium liquid glass modified with carbamidе and mixed in a scientific proportions with typical inorganic additives and kaolin in the pigment part providing the increase in their lifetime (≥ 120 days) was studied. It was revealed that the introduction to the composition of 20 wt. % of styrene-butadiene latex and introduction to composition of the pigment part additionly of chalk of 15-30 wt. % of kaolin instead of the titanium dioxide allows obtaining cost-effective, stor-age-stable materials suitable for the protection and decoration of facades of buildings and structures. Rheological characteristics of sustainable materials were the following: full power of flowing is 1.5–2.3 MW/m3; power to the destruction of coagulation structure is 0.45-0.80 MW/m3; consistency constant is 20–36 Pas; flow index is 0.30–0.50. The talc should be used as second filler at the preparation of light-colored compositions. Iron minium (Fe2O3) is one of the best components for a colored pigment mixture additionally including kaolin (30 wt. %). Recommended weight ratio of iron minium: kaolin is 2: 1. This protective material is charac-terized by the following parameters: full power of flowing is 1.8–2.1 MW/m3, power for the de-struction of coagulation structure is 0.70 MW/m3 and the flow index is 0.50.
