    • A repairing method using a repairing mortar composition containing a polymer is provided to reduce a setting time and to be inexpensive. A repairing method using a repairing mortar composition containing a polymer comprises steps of: removing a weak part of an upper plate of a concrete; cleaning the upper plate of the concrete from which the weak part is removed; maintaining a wetting state of the cleaned weak part; uniformly coating a polymer primer composition for repairing the upper plate of the concrete manufactured by adding water of 3~25 parts by weight based a polymer primer of the upper plate of 100 parts by weight consisting of a powdery polymer of 1-30 weight% selected from a PAE redispersible powder resin, POLY SAE redispersible powder resin, an ultra rapid hardening cement of 70-99 weight%, a POLY ethyl vinyl acetate based redispersible powder resin, and a PVA-VeoVa based redispersible powder resin at the weak part of the wetting state; and installing a mortar composition for repairing the upper plate of the concrete including water of 3~25 weight% and a powdery polymer of 1~10 weight% selected from the PAE based redispersible powder resin, the PVA-VeoVa based redispersible powder resin, the POLY SAE based redispersible powder resin, the ultra rapid hardening cement of 10~46 weight% in the upper plate of the concrete treated by the primer, aggregate of 50~86 weight%, and the POLY ethyl vinyl acetate based redispersible powder resin.
