ORGANIC COATING MATERIAL PROCESSING METHOD FOR CEMENT-CURED BODY AND UNFALLING METHOD FOR LATH MORTAR

摘要

PROBLEM TO BE SOLVED: To solve the problem that, in regard to the processing method for an organic coating material coated on a cement-cured body of a building exterior wall and an unfalling method for lath mortar, though a problem is temporarily solved with a treatment of a cement filler, if an existing coating film is in an active film state, when coating is applied over the existing organic coating material, the interface of the existing coating film can not discharge humidity to become an excessive wet state in most cases, causing a rapid chemical change to bring building into a musty state.;SOLUTION: The processing method for an organic coating material comprises steps of removing four portions per m² of the coated coating material of about 20 cm in diameter to expose the surface layer of the substrate cement-cured body 1; removing an organic coating material 2 of about 10 cm wide along cracks; removing adhesion inhibitors stuck on the wall surface; treating the entire surface with an SBR group cement filler to increase the adhesive force between the existing substrate layer and the subsequent process material; and successively applying a trowel pressure on the coating surface and urging the SBR group polymer cement mortar 3 to move while coating is executed to the thickness of about 2 mm with the SBR group polymer cement mortar 3 to bury a glass fiber net body 4 under the coating surface.;COPYRIGHT: (C)2006,JPO&NCIPI
