COATING REPAIR METHOD FOR FREEZING DAMAGE OF CORROSION MISSING PART OF JACKET MATERIAL FORMED BY FREEZING DAMAGE IN BUILDING STRUCTURE

摘要

To provide a construction method which inexpensively, easily and quickly coats and repairs a corrosion missing part formed by partial freezing damage such as snow damage while adjusting a color tone.SOLUTION: A corrosion missing portion 1 of a jacket material A formed by freezing and expanding, rupturing and peeling a moisture contained inside of a jacket material A due to snow melting in a winter season is subjected to: a first surface treatment work step of removing a degradation part to improve adhesion of a coating material; a second surface treatment step of forming a primer treatment layer a via coating means using a matrix resin of a fiber-reinforced plastic structure and a resin coating material formed of glass fiber bundle fibers; a third intermediate coating step; and a fourth top coating treatment step of forming a top coat layer c.SELECTED DRAWING: Figure 1
