发明名称 Drywall repair patch
摘要 A drywall repair patch comprises: a mesh sheet which carries a dry, pressure sensitive adhesive layer on at least one side thereof, and at least one layer of a dry, water hardenable cement product carried on a side of the mesh sheet. The mesh sheet is free of any rigid supporting plate. Further by this invention, water is applied to the water hardenable cement, typically after placement on the wall, followed by pushing a portion of the cement layer and mesh sheet into the hole being covered, without substantially breaking the adherence to the wall, to form a concave portion of the patch in the hole. After hardening, a second portion of water hardenable cement material is applied to form a smooth wall surface over the hole and drywall patch.
