FIELD: paint and varnish industry. SUBSTANCE: composition comprising epoxy diane resin, urethane modifying agent, solvent, polyethylsiloxane liquid and amine hardening agent involves oligomer as urethane modifying agent of the formula: with average molecular mass 1 900 Da containing 6-7% active epoxy groups. The definite ratio of components allows to enhance water resistance of coating by 1.5-fold and reduce the residue content in composition by 1.5-fold. Invention is designated for protection of concrete, metallic and asphalt-cement surfaces from chemical and atmosphere effect and decomposition. EFFECT: improved and valuable properties of composition. 2 tbl, 7 ex
