FIELD: process engineering.
SUBSTANCE: invention relates to producing glue joints and may be used in construction and woodwork. Proposed method comprises applying synthetic glue with acid curing agent on surfaces to be glued together and jointing them together to complete hardening. Said acid curing agent represent production wastes containing, at least, 80% of toxilic acid in amount of 0.5 to 2.0 weight parts per 100 weight parts of carbamide-formaldehyde resin.
EFFECT: higher strength, possibility to recover chemical production wastes.
