1, environmental protection function
When buying coatings, we must pay attention to the environmental protection characteristics of coatings. Among the harmful components contained in paint, formaldehyde is the most harmful to human body. Generally, regular stores have formaldehyde testers. Therefore, before buying the product, the clerk must use the standard formaldehyde tester to detect the formaldehyde content in the paint. You can only buy paints that have not detected formaldehyde.
2, paint film characteristics
When buying paint, many people only look at the model effect displayed by the specialty store, but the most common problem after decoration is the cracking of the wall, and the flexibility of the paint film cannot be seen through the model. It is suggested that samples can be tested on retractable objects, such as balloons and rubber, before buying paint, and then the ductility of the paint film can be tested after the paint film is dried. If the paint film can remain flexible, it shows that the paint film has a good effect, and it is not easy to cause wall cracking in the later use.
3. Anti-pollution characteristics
In the family decoration crowd, young people account for the vast majority, and there may be children at home now or in the future. For some experienced parents, they deeply understand the troubles caused by children doodling on the wall, so the pollution resistance of the wall must be within the consideration standard of buying paint. You can take a marker with you before you go to the specialty store. For the products you are satisfied with, you can scribble a few strokes on the model and then wipe it with a wet cloth to see how the paint film is stain-resistant. If it is not easy to erase, it means that the stain resistance of the paint film is not good, and it is recommended not to buy it.
4, mildew and antibacterial performance
Nowadays, with the rapid development of urbanization in China, high-rise residential buildings have become the trend of urban community construction, among which the most common problem for the residents at the bottom is shading, which leads to dark and humid indoors and easy to breed mold. For this part of users, when buying paint, we must pay attention to the anti-mildew and anti-bacterial characteristics to understand whether the performance is up to standard. The most direct method is to check whether there are signs of mildew and bacteria on the paint bucket. Both the residents at the bottom and the residents at the top will encounter moldy walls in their lives. It is recommended to buy mildew-proof and antibacterial paint.
What should I pay attention to in rainy season decoration?
1, let the tiles drink enough water. The vast majority of materials are isolated from water, focusing on the dry season, while tiles have to engage in "hydrophilic sports." In summer and dry season, the information about the soaking water demand of floor tiles and tiles should be extended, generally more than 4 hours, so that it is sufficient and close to saturation. This is not a simple explanation. When bonding, it is not firmly bonded with cement because of water absorption, which leads to hollowing and falling off. ?
2, wood drying before mount guard. In the dry season, wooden products used for decoration always "frown". First, because many building materials stores do not have enough storage space for materials, the moisture content of wood exposed to the wild will definitely increase after being watered by rain; Secondly, the rainy weather is low and the air circulation is slow. If the room is wet, so will the wood. As a result, after the wet wood was installed, it was blown by the dull autumn wind, and the "ugly state" such as cracking and tilting was exposed. Therefore, dry wood decoration should be "waiting for posts" in the dry season. When buying wood, the owner had better personally go to the site to check whether the materials are stored indoors or outdoors to determine the moisture content; Perhaps after purchasing the materials, please ask the decoration team to check with a moisture tester. Under normal circumstances, wood with water content within 1 1% can be "employed".
3. Resistant to painting In all decoration work, painters must not be "impatient", especially in the dry season, impatience will definitely become the "root of all evils". Because putty must be scraped before painting the wall, it usually takes 1-3 times, during which the normal drying time is 1-2 days. However, as soon as the heavy rain falls, the boring period of putty scraping will be forced to be extended, and the demand will have to wait for 2-3 days, maybe longer. It's best not to draw on rainy days. Take wood products as an example. When it rains, a layer of water vapor will condense. If you paint at this time, the water vapor will be firmly wrapped in the paint film, forming a turbid appearance, which will also lead to uneven color and a white scene. Regarding the latex paint on the wall, after the first brush, attention should be paid to appropriately extending the time for the wall to be stuffy.
4. Find a boring nest for the materials. Don't be a transfer worker in rainy days. Decoration materials are settled to be "retaliated". Therefore, it is necessary to ensure the ventilation of the borehole in the storage location. Once it rains, close the window immediately. Don't let rain spill into the house, use materials. In rainy days, it is best not to transfer decorative materials. If you accidentally "drink water" during the transfer process, it will be dangerous to use. 5. Prevent the copper wire head from "poking" the copper wire head outside the wire, and always like to "poke" to disturb the "decoration safety". Don't handle it casually, wrap the wire, especially be alert to the guys around the wet wood products to prevent the wires from being short-circuited by moisture.
6. New floor tiles can't jump. We plan to bid farewell to the messy shape in humid climate. The newly paved floor tiles usually have a slow cement setting speed, so don't spell its acceptance limit, try to prevent trampoline from stepping on immediately, and advocate placing springboard to walk when necessary to reduce touch. The personality of housing planning strives for accuracy, and tries to prevent those flashy decoration methods, especially the ceilings and partitions related to paint and wood.
7. Insist on indoor ventilation. On rainy days, because of the low air pressure, air activity becomes "slow" and many harmful substances cannot evaporate. Therefore, we must insist on space ventilation, or install indoor air purification devices to "infect" the turbid air in the decoration room, which is not only beneficial to the health of construction workers, but also helpful to the boring of indoor walls, floors and wood as soon as possible.
8. Grasp the reserved scale and train the "compression resistance" of gypsum line to be applied to wood floors, doors and windows. The former should consider the change of water content and leave a certain elastic coefficient; The latter pays attention to thermal expansion and cold contraction. Usually, the technical requirement of clearance is less than 2 mm In the dry season, this gap will remain more than in the dry season. Gypsum board and gypsum line are simply wet on rainy days. When using the connection, it is necessary to ensure that the time is relatively long, achieve appropriate compressive strength, and prevent wet cracking in spring.
9. Selection and production date of artificial board The latest selection and production date of artificial board is the latest. On the contrary, it is best to process the data of wooden keel for a long time. Before construction, open the wooden package as much as possible and let it dry for a while to make the data close to the indoor moisture content. When decorating, touch the position between the wall and the fixed wood structure, first brush the moisture-proof paint on the wood, and then cover it with moisture-proof cloth to prevent the wood structure from being deformed by moisture.
