The hollow drum, cracks and condensation of the external wall insulation wall are corrected, and the door and window openings are closed and improved. The iron railings, downspout brackets, aluminum alloy window frames, wires and various holes to be drilled in the wall on the balcony. The pipes are installed and completed, and the holes are repaired. After the exterior wall paint is completed, the glass installation should be carried out.

The surface of the base should be clean. The hollow drum, cracks and condensation of the external wall insulation wall are corrected, and the door and window openings are closed and improved. The iron railings, downspout brackets, aluminum alloy window frames, wires and various holes to be drilled in the wall on the balcony. The pipes are installed and completed, and the holes are repaired. After the exterior wall paint is completed, the glass installation should be carried out.

Before the exterior wall insulation construction, according to the design size of the exterior wall of the house and the technical requirements of the exterior insulation, the reference line should be hung and the control line should be punched. A vertical line is hung at the necessary parts of the outer corners and outer corners of the building, and a horizontal line is hung on the ground. The insulation board is a closed-cell ceramic material with high porosity, non-conductivity and strong heat storage capacity made by advanced production technology and high-temperature baking foaming process. Insulation material, durable, non-aging, exactly the same as the life of the building, is incomparable to traditional organic insulation materials.

This insulation board is suitable for building exterior wall insulation, fire isolation belt, building self-insulation cold, thermal bridge treatment, etc. The fire protection level is A1, which overcomes the fatal weakness of organic materials, which are afraid of open flames and flammable. Aging, filling the gap in domestic inorganic insulation materials. It is required to add the bottom alkali-resistant glass fiber mesh cloth to the wall part filled with fireproof insulation tape, and the vertical width of the mesh cloth shall not be less than 100mm on the outside of the insulation tape width.

The insulation mortar should be applied at least twice, the interval time should be more than 24 hours, and the thickness of each layer of plaster should not exceed 20 mm. Grid lines should be made according to the building facade and design requirements. After the insulation slurry is fully dried and solidified (pressed with the palm of your hand), it can be plastered on the fixed surface). Reasons for peeling off the surface of the insulation board: 1. The paint on the base is not dry. 2. The sealing primer is not in place. 3. The positive and negative corners of the corrugated line are not clear and the spraying is uneven.
