FIELD: construction engineering; smoothing concrete, plastered and wooden surfaces. SUBSTANCE: putty includes ground chalk, organic additive, surfactant and water; used as organic additive is aqueous solution of arabinogalactane and used as surfactant is spent lye change (waste of soap-boiling process) at the following relationship of components, mas.%: ground chalk, 73.0-76.0; arabinogalactane solution, 4.0-6.0; spent lye change, 10.0-12.0; water, 8.0-11.0. EFFECT: enhanced elasticity of putty; reduced hardening time; low cost. 2 tbl
