First, we must remove impurities such as dust and particulates, and remove moisture when necessary. Apply the patch to the pits, sand holes, corners, fissures and so on, fill them up and then scrape them. A scraper can also be arranged on the conveyor belt of the patching glue to facilitate uniform patching. Paper should be used to separate the upper and the lower plates to avoid bonding. After 2-4 hours of repair, the glue begins to solidify, then the surface of the board can be leveled, the best opportunity is to leveling before solidification, if conditions permit, can also add heating equipment, hot blower and other shorten the solidification time.
