        The manufacturer of color steel composite board glue said that before using color steel composite board glue to bond the board, the surface of the board needs to be treated first. The commonly used treatment methods are mainly:
        I. Solvent cleaning method: It mainly removes oil and other dirt on the surface. Generally, the surface is wiped or cleaned with an inexpensive and easily available organic solvent.
