The window cover near the heater cracked. Is there any way to handle it?

Construction quality problems are also caused by developers and construction units. The final construction quality is determined by the intervention of the developer to reduce the cost because of the lax operation of building materials and various technical links in the construction process. The use problem comes from the user. If residents make major changes to their houses, there may be problems. If the crack has penetrated into the putty layer, you can first use a sharp tool to enlarge the crack to the size of a screwdriver, fill in the caulking gypsum and grind it flat, paste grid cloth or kraft paper and level it with putty, and finally paint or paste wallpaper according to the normal process.

So what caused it? Very simple, let's talk about the way to repair the house at that time. Because it was customary to build a house at that time and the foundation was dug. If it's better, pile big stones with cement mortar. Almost directly throw a big stone into the foundation pit, then pile sand on it, and then wash the sand with water, commonly known as sand irrigation. When this step is completed, the whole beam will be watered.

And the continuous expansion will have an impact on the life and safety of the building. The possible reasons are uneven settlement of foundation, excessive upper load, incorrect calculation and reinforcement ratio, and cutting corners due to construction factors. But remember, the structure of all buildings is guaranteed for life for 50 years within the design service life! Some structural cracks are very small, mostly shrinkage cracks in concrete. Generally, this kind of crack has no effect on the structure and does not need to be treated!

Then start injection, the injection speed should not be too fast, sometimes the tape will bulge at the crack position, it doesn't matter, it will automatically penetrate into it until the whole crack is repaired, and the tape can be removed after two hours. If the crack repair agent 19 minutes is used, the adhesive tape can be removed in about 15 minutes. Treatment method: cut the crack as deep as possible with putty knife and fill it with gypsum. Be sure to fill it in. Then use bandage, bean wrap cloth or white polyester cloth to paste the cracks, dry them, and then scrape putty or do other technological treatment.
