Below is introduction of construction method of external insulation rock wool board

     Method 1: The specifications and external dimensions of the external insulation rock wool board must be selected as per design. Before using the adhesive to paste the insulation board, a surface treatment layer must be applied to the mineral wool board.
     Method 2: Lower-level handling, elastic control line and hang the reference line to ensure the flatness and verticality of the rock wool board assembly meet the conditions.
     1. Wall surface treatment: the wall surface should be cleaned. The loose and weathered parts of the wall should be removed and cleaned.
     2. Snap manipulation line:Snap the horizontal and vertical control lines of the external doors and windows on the wall, expansion joints, and decorative stitching. 
     3. Hanging the datum line: Hang the vertical datum steel wire at the large corners of the external wall (external angle, internal angle) and other necessary places, and hang the horizontal line at a suitable position on a floor to control the verticality and flatness of the rock wool board.
      Method 3: Preparation of external insulation rock wool board adhesive. Pour a certain amount of clean water into a clean plastic bucket, and use a handheld electric agitator to mix while adding polymer slurry powder. The amount of liquid added is about 20% of powder material; stir fully for 5-7 minutes, until the stirring is even, the consistency is moderate, and it can be used.
     Above is the introduction of construction method of external insulation rock wool board. Hope this can bring you some help.
