When the initial inspection, a sample can be selected and stepped on the foot to see if there is any obvious break. The glue strength is mainly to ensure the subsequent use of the product, that is, the turnover rate, in order to save engineering costs. When testing, you can select a sample and put it into the water for a period of time to see if there is any open glue.
Because one side of the black coated board for construction is in contact with the concrete, in order to ensure the quality of the concrete, the surface needs to be smooth and flat, and there should be no scars or scratches.
