Many houses will have empty drums after the decoration, and the empty drums will not only look bad but also cause harm to us. This is what we call the bean dregs project, because the empty drums are not in place when the wall construction is not in place. This phenomenon, so this is the bean dregs project, then what does the empty drum mean ? What is the cause of the empty drum? The following is a small series of decoration home network to introduce to you.
First, what does empty drum mean?
1. When the wall is added with the treatment layer, the base layer is not dry. For example, when the cement plastering wall is scraped with plaster, the cement plaster layer of the base layer is not dry, so the cement plaster layer is in the process of water evaporation, different materials. The treatment layer made on the wall, in the process of temperature and humidity change, its expansion coefficient is different, causing a change in volume, which causes it to form a delamination hollow with the gypsum layer;
2. The empty drum is caused by the presence of air in the original masonry and ash layer. When testing, use an empty drum hammer or hard object to tap the plaster layer and the leveling layer to make a buzzing sound. “Empty drum†generally means that the floor, wall, ceiling decoration layer (paste or paste tile) and structural layer (concrete or brick wall) are not firmly adhered or bonded.
3. If the wall hollow is not treated in time before the decoration or decoration, the wall will be cracked in a large area after the decoration. This is because in the wall painting construction of the house decoration, the wall putty should be applied to the wall, and the wall paint can be applied after grinding. However, the wall putty used in general is mostly the so-called environmentally friendly putty powder, that is, the putty powder in the factory has been produced. Incorporating glue, this type of environmentally-friendly putty powder is used after mixing with water and mixing, and wall paint is also required to be mixed with water. When the wall with empty drum problems encounters these waters Infiltrated, the water is sucked into the wall, and the water is contained in the wall, which is difficult to volatilize at once.
Second, what are the reasons for the empty drum?
1. The base wall plastering of the quasi-wall is not treated as required or the base rubbish is not cleaned up. Before the tile is laid, check whether the base plastering of the wall meets the requirements. The wall base debris, dust and must be cleaned; the cement mortar or 107 cement slurry on the back of the tile is covered with a hammer handle or a soft hammer. Knock the tiles to fill the back of the tile with a grout, then press firmly to firmly bond the tile to the base of the wall.
2. A small amount of local hollow drums appear on the tiles on the wall floor. Without affecting the installation of furniture, such as cabinets, mirror cabinets, showers and water heaters, it can be left untreated, but if it affects installation and daily life, it is recommended. Knock off this part of the tile and re-lay it. If you find a hollow drum on the edge of the tile, you can water the part of the edge of the tile, pry the gap between the tiles with a small shovel, then pour the cement into the gap, the empty drum will automatically suck in until the irrigation Solidify after filling, avoiding overall replacement.
No matter what construction is required, the construction will be in place. If it is not in place, then there will be problems, which will affect the quality of the project. What is the meaning of the empty drum and the reasons for the air conditioner? I think everyone can introduce it through Xiaobian. I understand that, if you still want to know more about decoration, please continue to pay attention to the decoration home Internet cafe.
