CEILING REPAIR METHOD AND WALL REPAIR METHOD

摘要

The present invention provides a method of repairing a plaster ceiling. The plaster ceiling to be repaired by the above described method includes: plates bridged across joists and spaced apart from each other; a ceiling base material finished with a masonry trowel over the lower surfaces of the plates; and a ceiling finishing material formed over the lower surface of the ceiling base material. The above described method includes the steps of: drilling an injection hole extending from the upper surface of the plate to the interface between the plate and the ceiling base material; injecting an acrylic resin composition containing: at least one monomer selected from an acrylic monomer or an methacrylic monomer; a thermosetting resin; and a curing agent; through the injection hole into the interface between the plate and the ceiling base material; and curing the acrylic resin composition so that the plate and the ceiling base material are adhered to each other. The invention also provides the use of the above described method.
