Some friends have found that black spots appear in the seams of the tiles in their own bathroom. Are these black spots the moldy of the tiles? How should they be handled? Below, Xiao Bian gave everyone a talk about the “mouldy†tile.
The moldy mold In fact, it is a grout
Tiles are refractory acid oxides and semi-metal oxides that are formed by grinding, mixing, pressing, glazing, and sintering to form an acid or alkali resistant porcelain or stone. Its raw materials are mostly made of clay, quartz sand and other materials. In fact, mold is not a tile, but a tile grout.
Tile grout, also known as the industry's grout, it is mainly composed of white cement, adding a small amount of inorganic pigments, polymers and trace antibacterial agents, consisting of dry powder material. The white substance in the tile connection of the general household is the tile grout.
The tile grout has become moldy and has nothing to do with the tile product itself. In the concealed corner of the bathroom, it is easy to see moldy condition of the tile grout, such as the rear of the toilet, the bottom of the sink, etc., which are not commonly used by the naked eye. However, kitchen areas that are similarly tiled in large areas are often exposed to the outside, and are generally relatively dry.
Why does the grout agent mold?
Although it does not rule out the possibility that the quality of the seaming agent itself may not be closed, it is often due to problems with the use of the seaming agent. The floor and walls are not cleaned for a long time, and they are not wiped in time after use. These will make the air in the bathroom space wet and cause the tile grout to become moldy.
When the indoor air environment is relatively humid, and the tiled floors and walls are dirty, and they are not cleaned in time, these dirt will be easily corroded on the grout, resulting in the appearance of white grouts on the surface. The more black spots. The shower room itself is a relatively closed small space. If the tiles are not wiped clean after bathing, then the shower room is very easy to return to the tide. If the corners are just filled with unclean stains, the seaming agent will mold. It is easy to appear.
In addition, the phenomenon of mildewing of general grouts occurs mostly in the wet provinces of the south and other regions. In the northern regions, especially in the dry Beijing region, if this method is used properly, this problem will not occur.
If the mode of use is appropriate, but moldy phenomena still occur in the short term, it is not excluded that the quality of the sealant products used by construction workers during the renovation work is problematic. Moreover, because the current tile work is mainly performed by the construction company's construction personnel, the acquisition of the tile grout is also done by the staff of the home improvement company.
Moreover, even if the product quality of the tile seaming agent is better, the product will have different reactions depending on the mode of use and the surrounding environment. What is the value of the indoor humidity in the home and whether the room is ventilated for a long period of time, which will affect the service life of the tile grout.
Use cleaner to remove
If you encounter a moldy condition of the tile grout, you can purchase a bottle of tile cleaner in the regular supermarket and you can wash it off. In addition, some cement residue cleaners sold by building material chain supermarkets will also have a certain effect on them. If the moldy condition is more serious, the above two methods can not completely eradicate these traces, so you can try again with the former home improvement construction personnel to allow them to repair.
The construction staff only needs to use a bottle of quality-guaranteed ceramic grout, and re-embed the spot where it has already emerged. But for non-professionals, this operation may be relatively cumbersome. At present, the quotations of such services are not high, and the costs are mainly concentrated on labor costs. The material fees are actually very low. At present, the construction fee for each construction worker is about 300 yuan per person per day.
However, it should be noted that if you want to find a tile brand to provide this service, then it is best to directly link with the after-sales service department of the tile brand used in the home, because the vast majority of tile brands are currently only for their own brand customers. After-sales value-added services.
The above is about the "mouldy" of the tile related to the discussion and treatment, in addition we need to pay attention, if the caulking agent inadvertently stuck on the tile, then within 24 hours after the completion of the jointing work, it is best to use a wet towel to Wipe clean.
