Methods for treating insulation materials in damaged areas of building exterior wall insulation

During the construction of building exterior wall insulation, it is inevitable that some problems will occur because some details are not well controlled, which will affect the quality of the entire insulation system. Faced with these problems, we must use correct methods to deal with them. Below we Some reference treatment methods are given for the insulation materials that are damaged when the external wall insulation of the building is damaged.

There are three main situations when the insulation material of a building's exterior wall is damaged and the insulation material is exposed: the exposed insulation material at the damaged area is intact, the exposed insulation material at the damaged area has been damaged or fallen off, or the insulation material is exposed through a large crack in the exterior wall. deal with.
1. How to deal with the damaged exposed insulation material intact
1. Shovel off all the exterior facing materials within 15 cm of the damaged area and its surroundings, and shovel off the damaged mesh cloth;
>2. Apply a layer of anti-crack mortar to the entire repair area, and press alkali-resistant mesh cloth into the anti-crack mortar (the size of the mesh cloth should ensure that the overlap length with the original mesh cloth on the wall is not less than 8 cm), and then add a layer of anti-crack mortar.
3. After the anti-crack mortar is completely dry (about 3 days), use the same decorative materials as other parts of the exterior wall to repair the exterior wall surface.
2. How to deal with damaged exposed insulation materials
1. Shovel off all the exterior facing materials within 20 cm of the damaged area and its surroundings to expose the mesh cloth, and use sharp tools to remove the damaged parts. Remove the damaged insulation material together with the mesh cloth on it;
2. Prepare vitrified microbead insulation mortar at the project site, and fill the area where the insulation material was removed with vitrified microbead insulation mortar. The height of the microbead thermal insulation mortar should be slightly lower than the exterior wall (but it should be ensured that the original wall insulation material at the edge is fully covered and not exposed to avoid fires caused during the construction process);
3. Equal vitrified microbead thermal insulation mortar After it is completely dry (about 7 days), apply a layer of anti-crack mortar to the entire repair area, and press alkali-resistant mesh cloth into the anti-crack mortar (the size of the mesh cloth should ensure that it is consistent with the original mesh cloth on the wall). The overlap length is not less than 10 cm), and then add a layer of anti-crack mortar;
4. After the anti-crack mortar is completely dry (about 3 days), use the same decorative materials as other parts of the exterior wall to repair it Exterior wall surface.

The treatment method for exposed insulation materials with large cracks in exterior walls is the same as the treatment method for intact exposed insulation materials in damaged areas. I will not write them out here. I hope that the above method can insulate the damaged areas of building exterior wall insulation. Helps with material handling.
