After the putty was scraped for two days, there were many large-scale cracks, what should I do?

Answering a question from an owner today. The owner said that the first time putty was applied to the house two days ago. I went to the house today and found that there were cracks in the putty in many places. He asked me what should I do in this situation?

This situation has also been asked by an owner a few days ago, so let’s analyze the reason.

The first reason is that the quality of the putty is too poor. The poor quality of the putty has poor adhesion and viscosity, and is easy to chalk and crack.

The second reason is that the putty is too thick, which is a problem that many old oilers are prone to make. Putty is used as a leveling material.

Some old oil masters have an outdated concept of decoration. In the past, putty needed to be glued. The amount of glue added was controlled by the oil master himself. I feel that the wall needs to be scraped thicker, and a little more glue will not cause cracks. , and now it is different. Now the putty does not need to add glue, just add water.

Some masters can scrape the putty to a thickness of more than half a centimeter for the first time, which is very dangerous. Once the surface of the putty dries too fast, and the bottom layer dries very slowly, the probability of cracks is very high.

In the national standard, it is written that putty is used as the surface layer, and the thickness is 2-5 mm. This thickness is not the thickness of one layer, but the thickness of the entire putty layer, and the entire putty layer needs to be scraped 2-3 times. That’s why the putty needs to be dry before it can be scraped off.

If the above mentioned situation also occurs in your home decoration, first check whether the implementation standard is written on the back of the putty packaging bag. If there is an implementation standard, it means that there is no problem with the putty, and the cracks in the wall are likely to be scraped by the putty. If it is too thick, shovel off all the putty in these places, first use plaster to level the wall, and then scrape the putty.

If the putty used does not comply with the standard or only has the enterprise standard, all the putty in the house will be shoveled out. These putty are time bombs. One day, when the whole family is eating, the putty on the top will fall to your rice bowl. in.
