The process of building external insulation board on the wall

Wandering. Clean the outside walls first to ensure the walls are flat, clean and dry. Treat and depress to ensure the base level is flat.
Jumping lines and punches. The horizontal line, vertical line and segmentation line appear at the bottom level, and then punch the segmentation line to embed the expansion bolt.
Fixed anchor. Use expansion bolt to fix H-type hanger and L-type anchor connector.
Make a binding solution. Make the solution compound according to the correct proportion and make sure it is used within one and a half hours.
Insert the insulation board. Insert the insulation board in a "frame" manner and use joint mortars and expansion bolts to fix the insulation board.
Treat the seams. Fill the bubble strip in the split gap, stick a beautiful paper tape on both sides, and then fill the silicone seal  and scrape it off.
Mesh fabric and mortar. Place the mesh fabric on the joints, apply the mortar of the bottom layer, then lay the mesh fabric and apply the mortar in the final layer.
Clean and protect. Clean the residue solution, glue and other dirt on the edge of the insulation board, dispose of the beautiful patterned paper, expose the protective film and clean it with a clean cloth.
