The most common problems with inorganic vitrified microbead thermal insulation mortar

The biggest problem of inorganic vitrified microsphere thermal insulation mortar materials in the construction of external wall insulation is that it is easy to produce hollows. How to avoid the hollowing problem is an important guarantee to ensure the quality of construction. Avoid hollowing of inorganic thermal insulation mortar in the construction of external wall insulation. The main control points are as follows.

Methods to avoid hollowing
1. The material is of good quality, has strong adhesion, and is well bonded to the wall;
2. The wall should be well moistened before construction, and the wall should be well moistened before application. Appropriate water absorption after construction (completely dry walls absorb water strongly);
3. Appropriate thickness for single application. Excessive thickness can easily cause debonding;
4. Do not apply any more water before and after the slurry absorbs sweat. Perform leveling construction operations to disturb the bonded surface. Therefore, it is recommended that in actual operation, any hollow drums larger than 10 cm in size should be required to be reworked and filled.

At present, inorganic vitrified microsphere thermal insulation mortar has been widely used in building insulation projects, and hollowing is the most common problem during construction. In order to ensure its quality, we are Please pay special attention to the above four points.
