What should I pay attention to when painting the wall indoors, and the precautions for painting the

If the wall is not painted well, it is easy to cause a lot of paint problems and various wall problems, which affects the wall decoration effect. If the wall is not good, it will look bad in the whole home. In the construction process, pay attention to the following aspects, you can easily avoid common wall decoration problems.

1.The ambient temperature of the construction should be higher than 5, the humidity should be lower than 85%, the pH value of the underlying substrate should be less than 10, and the moisture content should be less than 10%. Qualified construction conditions are the basis for painting the walls.

2.The unevenness of the base layer will affect the final decorative effect of the paint, and also increase the workload and material consumption of filling and finishing. Therefore, in terms of wall flatness, it is necessary to find the surface flat, the yin and yang angles are vertical, the façade is vertical, and the yin and yang angles are square.

3.The putty needs to be stirred evenly before construction to avoid the slurry containing powdery particles that are too late to dissolve, which will affect the overall construction effect. During construction, a single batch scraping should not be too thick, otherwise it is easy to cause more bubbles in the putty paint film.

At the same time, it is necessary to pay attention to the putty closing time, if you do not grasp it well, the surface has been dried and then the knife is retracted, and the powder will be depowdered. Avoid high-temperature construction, construction in humid environments, and construction before the base is completely dry, etc., which can avoid the occurrence of various paint diseases.

4.The paint should be stirred evenly before use, and diluted in the correct proportion, excessive dilution is very likely to cause chalking, color deviation and other defects. The dilution ratio should be comprehensively considered according to the environment, construction habits, product characteristics, decoration requirements, etc.

The dilution ratio should be reduced for dark paints to avoid color differences.

5.In order to obtain a smooth and delicate paint film, a short-haired roller should be selected, and a medium-haired roller can be selected if the substrate is rougher. Interior decoration generally does not use long-haired rollers.

Due to the difference in the amount of paint applied and the traces of painting, the difference in wall covering or color caused by the use of different tools should be avoided as much as possible. Large-surface roller coating and edge repair should be carried out continuously, not too long intervals, to prevent uneven blooming.

The wall must be flat and smooth, and the wall putty must be dried before applying latex paint.

Brush the primer first, then brush the topcoat, generally the primer once, and the topcoat twice.

The concentration of latex paint required by row brushes is higher than that of roller brushes.

Latex paint should be applied after the paint application is finished and the paint has dried.

In addition to inferior latex paint contains a large amount of formaldehyde, individual manufacturers use organic mercury in antifungal agents, ethylene glycol and other harmful substances in film-forming additives, the harmful components of excellent quality latex paint are relatively few, the common problems of latex paint, due to the quality of latex paint itself and the problem of painting, the painted wall often appears chalking, discoloration and fading, peeling and peeling, among which the reasons for chalking are: poor resistance of paint, poor wall treatment, paint to too much water film formation, etc.; The reasons for fading and discoloration are: high wall temperature, sunlight exposure, high alkalinity of the wall, and construction at the same time as paint will also cause fading and discoloration; The cause of peeling is simple, mainly due to the resurgence of the wall and improper treatment of the base layer.

Apply latex paint, and wait for it to dry thoroughly each time before applying it a second time.

Can interior and exterior paints be mixed? Mr. Zhu Chuan, the general manager of China Paint magazine, said that the exterior wall paint brush the interior wall, from the perspective of environmental protection, is no problem, and the interior wall paint is not necessarily used to paint the exterior wall, the exterior wall paint focuses on sun resistance and the interior wall paint focuses on alkali resistance and scrub resistance.

1. The temperature of the day of painting, if the temperature is above 20 degrees and relatively dry, then it is okay to brush the wall paint twice a day, but pay attention to the interval, the general interval should be more than 2 hours;

2. The humidity in the air, if the humidity is large, or it is rainy weather, it is recommended not to paint to prevent the paint film from absorbing moisture and blistering;

3. If the humidity is moderate and the temperature is also suitable, you can brush it twice a day; However, it is also necessary to pay attention to the separate brushing with the polyester paint to prevent the reaction and cause the latex paint film to turn yellow;

4. In addition, when there are more than 2 colors of paint in the home, and the color of the roof and wall is different, it should also be brushed separately to avoid color confusion and waste of materials by repeatedly washing the brush. If you have more questions, you can click on ID to consult.

The most important thing is that the wall should be dry and not have moisture, otherwise it will peel later. If it is scraped white, the old wall must be rolled into the wall.

In the process of decoration, we will inevitably brush some paint, the paint is to make our decoration more bright, so under normal circumstances, we will invite professional personnel, but at present, there are many friends in order to save a sum of money, so they often choose to act by themselves. So how do you paint yourself? What should I pay attention to when using paint?

If you choose the immediate service, the wall will be sanded dust-free and the wall will be thoroughly cleaned. If there is a place where the skin has fallen off, take putty knife 戕 [qiāng] and clean it.

2. Add water and white latex to the putty powder, and the putty powder should be stirred more.

3. Use a shovel to scrape the adjusted putty powder on the wall, not too thick, and try to be as uniform as possible.

4. After the putty powder is dry, it is necessary to carry out the hardest step of grinding, and use sandpaper to polish every uneven place with sandpaper, in fact, this step is the hardest because it is too difficult to test physical strength, and there is a lot of putty dust, remember to wear a mask.

5. Steps 3 and 4 are repeated n times according to their needs, but generally they can be repeated 2-3 times, provided that they must be dry before repeating.

6. After the putty is polished, you can do the last step, which is to brush the latex paint, which is relatively simple, and you can directly use a roller or brush to dip the latex paint on the wall. Latex paint can choose a high-efficiency deodorizing and anti-formaldehyde fresh breath anti-formaldehyde deodorizing full-effect wall paint, which is more assured to use healthily.

Precautions. 1. Stir the paint in the tank thoroughly before use, and then mix it according to the ratio requirements, and let it stand for ten minutes before construction.

2. The unmixed paint after opening the can must be resealed and stored in a cool place.

3. After the paint is ready, please use it up within 4 hours, and it is forbidden to pour the unused paint back into the barrel.

4. Please refer to the product label for details of production date, product name, net content, product ratio, etc.

5. Shelf life: 12 months (after exceeding the shelf life, it can still be used after a small area test).

6. After the construction tools are used, they can be washed with soap and water.

7. Please do not apply in wet or cold weather (when the temperature is lower than 5 degrees Celsius and the relative humidity is greater than 85%), otherwise the expected coating effect will not be achieved.

For interior decoration, painting the wall is an indispensable and important step. The quality of the painted walls and the use of paint will affect the overall housing experience and safety in the later stage. Whether you paint the wall yourself or hire a worker to paint it, you must pay attention to the steps and details of the draft when painting the wall.

These problems must be paid attention to when painting the wall in interior decoration: the influence of temperature and humidity, the color difference of wall paint, and the preservation of wall paint and paint.

When painting the interior decoration wall, pay attention to the humidity changes in the air. If the air humidity is high and the drying speed is slow, to be honest, you can use a dehumidifier or pants dehumidifier to speed up the drying speed. Otherwise, if it is very humid all the time, it will also affect the quality.

Conversely, if it dries too quickly, it can also cause cracks in the wall. Therefore, it is necessary to pay attention to the changes in air humidity at any time. In the summer, it is necessary to pay attention to the phenomenon of fake wall "drying", and be sure to let the workers confirm that it is completely dry before painting the wall paint.

When painting the wall in the interior decoration, you must not be in a hurry, whether it is natural drying or manual intervention, to ensure that the wall is dry, which is more conducive to the painting of the wall.

When painting the wall in the interior, some people will choose to paint the wall paint in a darker color, on the one hand, because they like it, and on the other hand, they feel that it is more resistant to dirt.

In this case, it should be noted that when choosing darker paint for interior decoration and painting the wall, it is best not to add any thinner to the paint, because this can avoid the color difference of the wall paint to the greatest extent.

The wall paint and paint used for interior decoration are flammable and explosive, so they should be placed in a dry and cool environment when stored in the dry season, pay attention to fire prevention, and avoid accidents.

When choosing wall paints and coatings, you must also choose products of qualified quality, pay attention to the national standards for such materials, and avoid inferior products causing adverse effects on the body after moving in later.

When painting the wall in the interior decoration, we must follow the construction process, grasp the progress of each level, and do not let the rush or other reasons affect the effect and quality.

<><What problems need to be paid attention to when painting the wall1. Choose to paint the wall on a sunny day If the construction day is a thunderstorm, do not paint, because the painting on rainy days is prone to uneven wall color, whitening and other phenomena, which has a great impact on the aesthetics of the wall decoration. If the owner needs to rush the construction period, an appropriate amount of whitening powder can be added to the paint, which can increase the drying speed of the paint.

2. If the construction day is a rainy day, and the wall is painted with latex paint, it will not have much impact on the decoration effect of the wall, but after the first latex paint is painted, the drying time of the latex paint should be appropriately extended.

3. Putty is like cement on the wall, it also needs a period of drying time to wait for the putty to dry before scraping the putty, so as to ensure that the wall can achieve a better decoration effect, especially on rainy days, to appropriately extend the drying time of putty.

Painting the walls requires painting, which is the last step, but the effect after molding is often determined by a variety of factors.

Now what is the beauty of painting the walls related to?

The simple ones can be divided into the following points:

First, the big inspection:

Cement wall: Comprehensively check whether the cement wall that needs to be painted in the blank room is solid and smooth. Putty wall: Be sure to check whether the wall putty is qualified water-resistant putty, if not, you must shovel off and redo the water-resistant putty.

2. Finished product protection: There will be dust when dealing with the wall, and it is inevitable that putty, paint or other glue will drip off, so we must do a good job in advance to protect the finished decoration products in the room.

3. Preparation before scraping putty: ensure that the wall is solid and flat, and brush the wall with a brush or other tools to make the cement wall as free of floating soil and dust as possible.

4. Scrape putty: Generally, the wall can be scraped with 2 putty, which can not only flatten, but also cover the background color. If the flatness of the putty is poor, it needs to be scraped several times more locally. If the flatness is very poor and the wall is heavily tilted, you can consider scraping the plaster first for leveling, and then scraping the putty.

5. Grinding putty: After the water-resistant putty is completely strengthened, it will become extremely solid, and it will become extremely difficult to polish it at this time. Therefore, it is recommended to start putty grinding 1-2 days after scraping.

6. Brush the primer: After cleaning the floating dust on the surface of the sanded putty, you can apply the primer. The primer can be applied once and must be even.
