building materials, more particularly cold hardening urethane compositions used for anticorrosive and hydroinsulating coatings of metals, wood and concrete. SUBSTANCE: composition comprises wt parts: product of reaction toluylene diisocyanate with polytetrahydrofurandiol with molecular weight of 1000-2000 and/or 1500- 2060, 100; 25-40 % solution of coal tar in toluene, 70-100; and filler consisting of double of triple mixtures of cement, gypsum, talc, kaolin, finely divided sand at ratio for double mixtures of 1:10:10-1, for triple mixtures of 1:1:1, 3-7. EFFECT: high deformability of the resulting coating. 2 tbl
