Wall decoration is a major project in home improvement. Paint is also an essential building material for wall decoration. What are the precautions when painting a wall? How should our owners do a good job of supervision? Following Xiaobian together to understand it.
Check accessories and primer model
Like the glue used to reinforce the bottom surface and various accessories for wall decoration, the user is not familiar enough with the situation that the use of inferior materials and the transfer of dragons to the phoenix are most likely to occur during construction:
1. The wall backing glue is forbidden to use 107 glue. 107 glue is used as a decoration material for interior decoration. In recent years, it has been banned from use by the State. Its excessive formaldehyde is unhealthy. Users should pay attention to preventing the construction team from using it for convenience.
2. The new interface agent pays attention to environmental protection - it is best to avoid the use of glue. There are many interface agents on the market that can be used to reduce the pollution. The user can purchase the environmental interface agent and avoid using the construction personnel. With glue.
Putty to shave thin and dry
After the leveling and reinforcement of the shovel wall, it is necessary to scrape the putty powder, and the putty scrape is not smooth and dry. The relationship between the finish of the wall paint and the cracking of the wall paint will not be cracked. To supervise the work in person:
1. Put an end to the construction staff to save a layer of putty for saving trouble. Even if thick putty is hard to dry, the thinner the putty is, the better (dry faster) is 0.5-1mm.
2. Emphasizing natural air-drying and drying-out - Many construction teams began to paint the latex paint for the next time as soon as the putty did not dry out. The scraped putty must naturally dry and be sure to dry.
3. Make sure that the putty scrapes at least twice - if the construction staff tells you that it's unreliable at once, put the putty at least twice, three times better, and keep the scraping time two hours or more on two occasions.
Supervise the ratio of latex paint to water
After completing the greasy and good anti-alkaline primer, some users will choose latex paint, and the construction will generally dilute the latex paint, and the watering ratio chosen by the constructors is also very particular:
1. The water is more easily cracked. The more dilute the latex paint, the easier it is to construct. Many construction teams add a lot of water to the latex paint in order to increase the construction speed. However, after the completion, the wall surface is prone to cracking and flowering.
2. The ratio of watering is generally 20% - 20% of the ratio of water is more appropriate, over-dilution can brush a lot of area, but the quality of the problem is worrying, poor control of the proportion is also a waste of paint, user repair problems are also troublesome.
3. Stir thoroughly after mixing with water—Latex paint must be well-mixed after mixing with water. It is recommended to use a special stirrer for more technical protection.
Ensure the quality of wall paint
1. Confirm the use of water-based paint - water-soluble paint is the general trend of the paint market, good environmental protection and colorless and odorless, no precipitation and agglomeration is the best product.
2. Check the paint certificate - the national environmental protection standard; the green ten environmental protection type II mark; the qualified test report of the latex paint product; the anti-formaldehyde report (the report must have the CMA check mark) detected by the third party organization, etc. One or two of the above certificates.
3. To avoid the superposition of environmental protection building materials - even if the coating is environmentally friendly, the floor is environmentally friendly, the furniture is also environmentally friendly, or should pay due attention to control the number of these building materials, green building materials does not mean zero formaldehyde, superimposed or there may be excessive formaldehyde.
How to decide the construction method?
There are many construction methods for wall painting projects. Currently, the three main methods include roller painting, spraying, and airless spraying. According to different needs, the user can request the construction team to use different construction methods:
1. Brush the paint with the least loss – the brush is the most economical material, but it is time consuming, work slowly and slowly, and when you manually brush, you must start from one point and start sequentially.
2. Faster spray drying time - spray gun method is preferred for wet days, high efficiency, fast spraying speed, and faster drying speed of paint film. Be careful to prevent dust from falling into the paint during operation to avoid causing paint filming. .
3.Airless spraying is exquisite but the loss is high - At present, the most popular method in China is the use of high pressure airless spray process, the surface effect is delicate, the quality is excellent and the coating coverage is relatively high, but the loss of material is large
Editor Comments: The wall decoration is a large area of ​​work, it requires high-level engineering and details of the operation, so it is recommended that the choice of large brands of home brushing services or professional construction team will be more secure.
