What is the process of painting the wall? What process is required to paint the walls

1. Remove the wall.

Carry out a simple treatment of the wall and remove the original white ash of the wall.

2. Wall leveling.

After the white ash is removed, it must be leveled again.

3. Scrape putty.

When brushing putty, it should be well blended, not delicate, because it is directly related to the quality of the bridge deck in the later stage.

4. Sandpaper sanding.

There will be some coarse places when brushing and scraping putty, or some places that are difficult to cover, which can be sanded with sandpaper.

5. Paint the topcoat.

It is important to remember that do not add water.

Brush wall paint selection points.

1. Choose a regular point of sale: try to buy in the ordinary market or a store with more credit, and choose a professional brand: the choice of paint does not have to buy that kind of fame, but it must choose a professional.

2. Depends on the aqueous solution: the coating will be layered under static conditions, the upper layer is 1 4 aqueous solution, if the aqueous solution is colorless or light yellow, there is less floating substance, and the coating quality is better.

3. It depends on the fineness of the paint particles: put a small amount of paint into a glass of water, the water is clear after stirring, the particles are independent and non-sticky, the size is uniform, and the paint quality is better.

4. Look at the drawings: take a small piece of sticky latex paint, which can be hung for a long time and continue to fall evenly.

5. Test the feel: apply enamel with your fingers, there is no rough sand texture, and there is a smooth feeling when rinsed with water. The smell of the smell: the environmental protection coating should be water-based, non-toxic and odorless; Do not buy additives.

The process is as follows: <>

1. Wall repair.

Before painting the wall, the wall foundation must be done well, and it must be kept flat and firm. Therefore, we need to deal with the loose position of the wall; If there are grooves, they should be smoothed with cement mortar;

If there are some fine cracks on the wall, professional wall repair materials should be used to repair them, or white latex can be used to stick to the mesh, but white latex must be selected. If there are protrusions on the wall, it needs to be smoothed.

2. Scrape putty powder.

Scraping putty powder is also a step in laying the foundation. Putty powder can make the wall a little smoother. When you buy putty powder, try to choose putty with high particle fineness and hard texture, in order to make the effect of wall paint painting better, scrape putty, we generally scrape three times, the first time is thicker, and the second or third time can be slightly thinner; The wall surface treated in this way is smooth and flat, and it is not easy to crack.

3. Wall polishing.

If there are uneven parts of the wall after scraping the putty powder, then the wall needs to be sanded. In order to make the effect on the wall paint better, the putty bottom must of course also be dealt with. Otherwise, the dust is too thick and the adhesion of the wall paint will be directly affected.

Fourth, brush the primer.

The primer must be applied before painting the wall. When brushing the primer, it is necessary to ensure that every position can be brushed, and there is no need to brush it two or three times, but only to brush it all once. If the primer is unevenly brushed, the wall paint will appear yin and yang wall, which everyone must pay attention to.

Fifth, make amends. Repair is the last time to repair the wall before painting the wall. Because after the putty and primer are applied, some imperfections will be revealed. In these cases, we can add a little water-mixed primer to neutralize the color difference.

6. Paint the walls.

Brush the wall paint, do not overdo it, this will affect the thickness and feel of the paint film. The drum hair should not be short, and the hair quality should be fine, and the brushing of the top coat should maintain a uniform speed. After the first brush, brush the second time every 2-4 hours.

It takes 1-2 days for the topcoat to dry, so keep in mind the time if you need to do other wall decorations.

There are at least 8 processes for painting the wall, and the specific process content is as follows:

1. The yin and yang angles should be leveled.

2. The construction wall should be repaired.

3. The wall should be cleaned without dust and other stains.

4. Paint the interface agent on the wall.

5. Batch scraping putty, 2-3 layers are recommended.

6. Use suitable sandpaper to polish the wall.

7. Evenly paint latex paint on the wall.

8. Completion acceptance.

What are the common problems of wall painting:

1. The construction effect is not good: the color can be adjusted according to your preferences by using latex paint to brush the wall, so there are often situations where the idea does not match the reality. In order to avoid similar situations, it is recommended to find professionals to carry out color matching and construction during construction.

2. The wall is uneven: when scraping putty and painting latex paint, it is required that the base layer of the wall must be cleaned and smooth. If there is a protruding place, it needs to be shoveled, and if there is a pothole, it needs to be leveled with putty, so as to avoid latex paint potholes.

3. Poor film formation of latex paint: When brushing latex paint on the road, it is necessary to add an appropriate amount of water for blending, so as to make the construction of latex paint simpler and make the color of latex paint more natural. But be sure to pay attention to the control of water volume, which is generally between 20% and 30%.

If there is too much water, it is difficult to form a film, and if there is too little water, construction will be difficult.

4. Uneven color of latex paint: During the construction of latex paint, the painting must be uniform, and it is best to pass it in one stroke, so that it is not easy to have uneven color.

The process of painting the wall is very simple, and you must accurately grasp it yourself.

1. Remove the wall.

Before we started construction, we had to treat the walls. The white ash of the original wall is removed, and then the interface agent (wall solidification) is applied to the roller, and the cement layer is sealed and connected.

2. Wall leveling.

When the white ash of the original wall is removed, the next step is to carry out two leveling work on the wall. One is the horizontal correction of the lowest layer of the wall, when the detection error of our wall flatness exceeds 10mm, we can consider using cement for leveling.

3. Scrape putty.

Batch scraping putty is a very important step in wall construction, which will be directly related to the quality of the wall in the later stage. It is better to choose putty with higher particle fineness and harder texture during construction, and if the texture is softer, you can also add a limb or fixed white latex to the putty to improve the hardness of the putty.

1. Preparation before construction.

1. The wall should be kept dry, the surface moisture should be less than 6%, the pH value should be less than 9, and the new cement construction should generally be maintained for 20 to 40 days.

2. Before construction, it is necessary to remove bulges, remove oil, remove dust, remove alkali, remove mildew and loose layer, etc. In addition to the occasion, it can be rinsed with dilute acid water, then rinsed with clean water, and then brushed with paint after drying; When removing mold, first use a shovel blade to remove the mold on the construction surface, and then use wall washing water, spray and wash twice, and then brush the paint after drying.

3. During construction, a small amount of water or dilution can be added according to the different climatic conditions and the specific painting (please refer to the instruction manual of each variety for the specific amount added). When the temperature is lower than 7 °C and the humidity is higher than 85%, it is not suitable for construction.

4. Do not use polyester paint materials while painting wall paint, because free ion TDI will make the glue paint yellow.

4. Apply the first coat of paint, refill the putty, and remove the surface dust after polishing.

5. Apply the second coat of paint, remove the surface dust after polishing and use water sand skin for water grinding.

3. The order in which the walls are painted.

1. First of all, paint the ceiling, starting closest to the natural light source and gradually moving away.

2. Secondly, paint the walls, from top to bottom, about two feet wide each time, also starting from the natural light source, and then gradually moving away.

Painting a wall requires wall repair, putty scraping, wall sanding, primer and topcoat.

Wall repair: Before painting the wall, be sure to clean the wall, otherwise it is very easy to leave particles and affect the overall appearance. In addition, if there are cracks in the wall, you can fill it with stone education, or paste it with white latex, and then paint it later.

It should be noted that after using the stone filling, in order to avoid unevenness, it is necessary to carry out leveling before painting.

Scrape putty: Scrape putty at least twice, and make sure the wall is dry and clean before construction. When constructing, in addition to uniformity, it is also necessary to grasp the thickness, and each layer should not exceed three millimeters.

In addition, putty powder is the basis of stucco, and you should try to choose the best one, with good water resistance and hard texture.

Wall sanding: After brushing the putty powder, you need to choose a moderate sandpaper for sanding, so that the primer can be more firmly attached to the wall. But remember to clean it after sanding, and the sandpaper used for sanding should not be too thick, otherwise it will be troublesome to leave scratches.

Brush primer and topcoat: There must be a careful technique for brushing primer, and every corner must be evenly brushed, otherwise the overall effect will be affected. Once the primer has dried, it's time to apply the topcoat.

The technique is similar to that of primer, but in order to make the overall effect better, it is best to apply the topcoat twice, and when you brush it a second time, you can do it without waiting for it to dry, about two to four hours.

What should be done by painting the wall?

To ensure that the wall is clean and smooth, the wall should be cleaned in time to remove the dust and other substances floating on it, and if necessary, a professional grinder can be used for base treatment. When grinding, it should be evenly not worn through, and the surface dust after grinding should also be removed in time. Before painting the walls, stir the paint in the bucket thoroughly.

Due to the difference in the construction method of wall painting, the number of application passes of primer and topcoat can be adjusted according to actual needs. However, in order to achieve a good coating effect, it is necessary to use a brand of products together, do not mix various brands of paints and coatings with different properties, and at the same time can avoid adverse reactions.
