Hollowing is a common quality problem in housing projects. It means that the decoration surface layer (plaster layer or tiles) and the base layer are not handled well and the combination is not tight, resulting in a gap space between the base layer and the decoration surface layer. Use hard objects to You will hear a drum-like sound when you tap it lightly, which is called "empty drum" in engineering. If there is a hollow phenomenon in the wall and it is not discovered during the later decoration and construction, it may cause cracks to appear after the paint is applied, and the wall skin will fall off over time. If ceramic tiles are installed, the hollow wall will not be able to hang the tiles. , it will easily fall off after a long time.
What is the reason for hollowing on the ground?
1. The hollowing on the ground may be due to the fact that the surface of the base layer is not cleaned during construction, or the surface is not moistened enough when watering. Hollowing will occur in the later stage. If cement is applied, If the slurry bonding layer is uneven or the painting time is too long, the cement slurry will harden and lose its bonding effect, which will also cause the surface layer of the plate and the base layer to hollow together.
2. The floating ash on the back of the slabs was not brushed off and soaked in water before the surface layer of the slabs was laid. If the dry slabs were directly laid during the construction process, the moisture in the cement mortar would be quickly absorbed by the slabs, causing the mortar to become dehydrated. It affects its coagulation and hardening, which will reduce the strength of the mortar and affect the adhesion between the mortar and the plate.
For example, the floor tiles laid at home are hollow. The most common situation is that the floor tiles have hollow holes in the corners. For example, when we use a hollow hammer to hit the ground, we find that most of the floor tiles are very dense, with only hollows appearing in the corners. For this situation, I personally recommend the following suggestions for handling this situation.
If some of the corners of our indoor floor tiles have hollows, my personal opinion is that we don’t need to deal with them. In other words, even though we found hollows at the corners of these floor tiles, most of the floor tiles are very dense. In this case, even if these hollow floor tiles are not treated, there will be no problem. But in this case, I would like to give you a suggestion, that is, you must do a good job in making beautiful seams on the tiles. Prevent this gap from getting worse due to hollowing.
Everyone should have a brief understanding of the hollowing of indoor floor tiles. Because empty drums are divided into different situations, the required processing methods are also different. And the hollow drum has its own specifications and corresponding requirements. Because if this issue is not explained clearly, it may cause us a lot of disputes.
