THE URETHANE COATING WATERPROOF METHOD OF THE ROOF AND THE GROUND OF BUILDING USING BY THE EMBOSSMENT SPRAY COATING SYSTEM THAT MAKES EMBOSSING LAYERS

摘要

An urethane coating type waterproofing method for the rooftop or the bottom of a building is provided to prevent a slide when performing a repair work for the bottom of a building or walking, and to keep the thickness of a modified urethane resin layer regularly and to enhance elongation against deformation such as expansion and contraction, relaxation or flexural deformation of a building. The urethane coating type waterproofing method for the rooftop or the bottom of a building for forming an embossed pattern layer using an embossment spray coating system comprises the steps of removing a corroded mortar layer from the bottom of a building, drying a base for surface treatment and removing filth, oil, etc.(S10), applying 1-liquid primer on the surface regularly using a roller(S20), placing modified urethane waterproof materials of roughly 4mm on the 1-liquid primer using a trowel, etc.(S30), forming an embossed pattern layer in roughly 1mm by spraying non-sag type 2-liquid color urethane resins on the modified urethane resin layer using a mortar gun(S40-1), forming a top coating layer by coating the modified urethane resin layer with oil-based coatings using a planetary roller(S50-1), and finishing and curing(S60).
