Ask about the problem of painting the wall, the quality of the wall painting is common

1. The area of your house is 100 square meters, and the area of scraping putty is calculated according to 200 square meters, which is normal and not much.

2. 10 yuan per square meter, it should be a labor cost - this ** is not high! The materials (including paint) should be purchased by yourself.

3. If you repaint in the future, it is best to remove all the current putty layers - reconstruction; If you want to remove the current putty layer completely, it depends on the adhesion (firmness) of the current putty layer. Or, if the time gap with this construction is not very long, it should be directly rolled on top of the current paint.

4. It is not advisable to directly paste wallpaper on the surface of the paint layer, and the putty layer should be removed, and the putty should be re-approved for leveling, brushing the base film, and then the wallpaper can be pasted.

5. Above, hope, thank you!

Generally speaking, the painting area = construction area * As for the 10 yuan per square meter you said, is this a simple public expense? Or does it include what you call a regular paint? I don't know if the ordinary paint you are talking about is wall paint or putty paste as some regions say.

If the brush is the wall paint, the decoration depends on the specific situation of the wall, if the hanging is water-resistant putty, the decoration only needs to repair the damaged part of the wall, and you can brush the wall paint or paste wallpaper after a simple polishing If the hanging is not water-resistant putty, it is recommended that the original putty and plaster should be removed when the second decoration is also needed to do plaster leveling, scraping putty, painting wall paint or wallpaper.

Common problems in the quality of wall painting: common problem 1: the reason for the hollow drum crack in the wall plastering layer 1, the base layer is not well treated, and the cleaning is not clean.

Reason 3, a plastering is too thick, and the intermittent time of each layer of plastering is too short. Prevention and control plan: At the junction of different base materials, the metal mesh should be nailed, and the lap width on both sides should not be less than 100mm.

Layered plastering can not exceed the specified thickness, where greater than 9mm layered thickness should be layered plastering, divided into survival. Reason 4: The wall is not watered enough to be moist, and the moisture in the mortar is easy to be absorbed, which affects the adhesion. Prevention and control program:

The base wall should be watered before plastering construction, and it should be poured thoroughly and evenly, so as to ensure that the watering depth enters the wall 8 10mm, and the brick wall should be watered more than twice a day in advance, and the speed of water absorption of aerated concrete wall is fast and then slow, and the water absorption is slow and lasts for a long time, and the number of times of watering should be increased, so that the plastering layer has better coagulation and hardening conditions, so that the water will not be sucked away by the aerated concrete in the process of mortar hardening. This answer applies to wall painting in most cases.

If it is not firmly bonded, hollow drum and crack, when plastering the inner wall of Dan Trembling Source, it is sometimes found that the bond between the stucco layer and the substrate is not firm, resulting in hollowing, cracks and other problems, which is mainly because the base is not clean and not wet enough, and in the process of hardening the strength of the mortar, uneven shrinkage stress is generated, so the phenomenon of dry shrinkage cracks is formed.

If the plastering layer is too thick, the plastering layer can be cracked at this time, and the thickness of the plastering layer can be controlled in a certain range of holes, keep about 20mm, the operation should be layered, intermittent plastering, the first time the ash solidifies before the second time, must not be completed at one time.

If it is an interior wall plastering, it is easy to have problems such as hollowing and cracks on both sides of the window frame, so in order to avoid this situation, a special person should be responsible for the door modal window cracks.

In the process of decorating human settlements, murals are very important, and many newcomers are not very familiar with the painting process and wall requirements. Today, will answer for you, want to know friends may wish to share withPaint the walls yourselfWhat is the process!

Paint the walls yourselfOne: wall restoration.

Before you start painting your walls, be sure to clean the walls that need to be painted. If there are irregularities and irregularities, fill them with cement grout to keep the wall clean and smooth. To carry out leveling work on the wall, it is possible to use plaster dust to make people.

Paint the walls yourselfOne: putty.

The putty wall is applied three times, and the thickness of the putty must not be greater than 3 mm after three times, otherwise, the wall will be prone to cracking and sagging.

Paint the walls yourselfOne: the wall is thrown to Changguang.

Wall sanding should be done using fine sandpaper. If you use sandpaper that is too thick, it is easy to leave sand marks and even affect the aesthetics of the wall. There is another important step in the process of polishing the surface of the wall.

After polishing the wall, the wall surface must be cleaned. Otherwise, there is too much powder, which can easily affect the adsorption of the coating.

Paint the walls yourselfOne: primer brush.

The next step is to apply the primer. Pay attention to the balance of the primer when applying the primer. Make sure that every place can be brushed to make the walls smooth and flat.

Paint the walls yourselfOne: Brush it up.

After the primer is finished, brush the finishing layer. When using the topcoat, do not add too much water, otherwise it will affect the concentration, thickness, hardness and feel of the paint film.

Precautions: Pay attention to the weather, paint the wall to prevent the weather, such as rain and snow before, thoroughly remove the mold, oil, fly ash, loose lining, shovel wall on the wall, and then wipe it with coarse sandpaper. If there are vulnerabilities and leaks, fix them in time.

When decorating, you can use a top-to-bottom approach, with a straight brush or a left-to-right and crossed brush. In order to avoid different shades on the surface of the wall, the white stucco should be continuously stirred during the brushing process.

When decorating the house, the walls must be painted so that the walls will not look so ugly and make the whole room look bright. How do you paint the walls? What are the specific methods? The following is an introduction to the treatment method of painting the wall.

The basic treatment methods of different walls are slightly different, but the overall requirement is that before painting, the base layer should be smooth and clean before painting the wall. For the wall of the rough house, it is necessary to find a flat surface to clean; In order to paint the wall, the old paint needs to be removed when painting the wall, and it takes more than 5 years to remove the putty; For walls that were originally wallpapered, tear off the wallpaper and dispose of it.

After the basic cleaning of different wall roots is completed, you can choose to brush the interface agent when painting the wall. The interface agent is of great help to the adhesion of the bottom layer, which can prevent the phenomenon of hollowing and shelling of the gray layer. When brushing the interface agent, it must be brushed evenly.

If the brush is not good, the thickness will be different, and the effect is very bad.

Equalization, after brushing the interface agent, it is necessary to find out the uneven area of the wall. For such a wall, gypsum can be used to smooth the surface, so that the wall error does not exceed 3mm. If the error is too large, the light will be cast on the wall, and the light will be dazzling.

Therefore, the work of this stucco wall treatment process should be standardized as much as possible.

Waterproof, if there is a waterproof wall in the kitchen, balcony, etc., it must be painted with waterproof paint. In the past, the anti-Hu Jingshui materials only needed a simple brush, but now the new waterproof coatings are mostly two-component, and even potato banquet is three-component. Therefore, before painting the wall treatment, it is necessary to know how to deploy and what proportion of the deployment will be.

If not proportional, the waterproofing coating may not achieve the original effect. In that case, the waterproof effect of the wall will be greatly reduced, and there will even be a phenomenon that it cannot be protected from water. Because waterproofing these areas is important, water is often used.

The above is an introduction to the treatment method of stucco wall.

After using the wall for a long time, stains, blistering, cracking, chipping, chalking, etc. will inevitably appear due to various reasons, so it is necessary to repaint the wall, thenHow to paint the wallsThis? Here's howHow to paint the wallsSpecific steps and precautions.

The materials needed to paint the walls include: primer, gypsum powder (or quick-bonding powder), white latex, caulking tape, putty powder, 360 mesh water sandpaper, latex paint (primer, midway and topcoat).

1. How to paint the wall and clean up the old wall

First, the walls should be cleaned and then the raised surfaces should be shoveled. For oil and stains, the coating should be removed directly.

2. Scrape putty powder

After the wall has been processed, the putty powder needs to be re-selected. When choosing putty, it is best to choose putty with high quality and hard texture.

3. Grinding

Use finer sandpaper to polish the walls to reduce damage to the walls. If you are using a soft texture, you should use 400-500 sandpaper. If the texture of the putty used is hard, then use 360-400 sandpaper.

Also, when polishing the walls, one must remember not to use too much force so as not to leave scratches on the walls.

4. How to paint the primer on the wall

The primer is the foundation for the topcoat. When applying primer, not only should it be applied evenly, but also make sure that every part of the wall is painted. If the wall area is large, some water should be applied appropriately when applying the primer to ensure that the primer on the wall is applied more evenly.

5. Make amends

The flatness of the wall should be checked before painting, as only some wall pits and small bumps can be seen at this time, so it is essential to ensure the flatness of the entire wall.

6. How to paint the top coat of the wall

The top coat is actually a brush topcoat. It is best to choose a high-quality wool brush or roller for tools.

7. Maintenance

Under normal circumstances, it takes 4 hours for the surface latex paint to dry after construction, although it takes 4 hours, but this time the latex paint cannot be completely dried, so you must wait until the latex paint is completely dry before you can treat the wall.

The above isHow to paint the wallsTake a look at the specific steps and precautions.

1. At the junction of concrete pillar and brick wall, hang a layer of cement mortar with nylon net, and the effect of nylon net is to reduce cracks in the combination of concrete and brick materials, increase the strength of the leveling layer, and ensure that the wall is not cracked.

2. White cement, gypsum and construction glue are made into putty, which is used for batch ash and leveling. Architectural paint can only be brushed after the ash is approved.

With the continuous development of society, housing prices are now rising very sharply, and it costs a lot of money to renovate a house, and many people choose to have insufficient budget during construction, and the construction cost is too high. will choosePaint the walls yourself, then I will talk about itPaint the walls yourselfWhat are the strategies andPaint the walls yourselfprecautions.

1.First of all, choose the right tool, the better the wall brush effect, the better the quality. It better covers the original original color, making the paint film durable and able to withstand repeated scrubbing.

2.Before painting the walls, attach the floors, wardrobes, doors, and corner lines to the paper so that they don't get smudged or torn after the construction is complete.

3.Before painting, the dust and dirt on the walls should be cleaned, and nails and small cracks should be filled with filler.

4.Brush the outside with a brush first, then roll with a roller. Roller coating can be carried out in the form of "W" or "M" and can be applied in different directions.

1.Take care to save the paint.

Paint is flammable and the temperature is relatively high, especially in summer. Otherwise, it may lead to a disaster. Therefore, the paint should be stored in a cool, well-ventilated place, and the storage container must be sealed and isolated from flames and wire outlets.

2.Extend the drying time of putty on the wall.

The putty should be scraped twice and dried for 1-2 days. If it is summer, extend the drying time of the putty. Due to the hot and humid weather in the summer, the drying time will be longer. When scraping putty, wipe off the water vapor from the wall with a dry cloth to keep the wall dry. It is recommended to paint the walls.

3.Walls are difficult to handle.

In the summer, the wall surface is prone to falling into the illusion of drying, so the construction workers have to pull the wall because the base layer is completely dry. High humidity and high temperatures make walls difficult to dry, and dehumidifiers can be used to speed up the drying of wall surfaces.
