Waterproofing method using polyurea and surfacepreparation compound
2009
PURPOSE: A waterproofing method for a concrete structure using polyurea coating is provided to improve stability and superiority by completely attaching and securing a coating layer to the bottom of a concrete structure. CONSTITUTION: A waterproofing method for a concrete structure using polyurea coating is as follows. The bottom layer(10) of a concrete structure is surface-treated. A primer layer(20) is formed over the surface-treated bottom layer. A plating layer(30), a surface control substance film, is constructed on the primer layer. A coating layer(40) is formed on the plating layer by spraying a coating material including rapid-hardening polyurea resin.
