Wall latex paint construction process.

First of all, the impurities on the wall should be cleaned up, after making sure that the wall is free of impurities, start to scrape putty, and use sandpaper to polish the wall flat, and then start to paint the primer, when painting, you need to ensure that every corner of the wall is painted, after the primer, the pit hole of the wall is polished and smoothed, and finally the top coat is painted, and the wall shall not be touched or scrubbed within ten days after painting.

<> "Latex paint is one of the commonly used materials for wall decoration, and installation steps are required when painting. So, what are the steps of latex paint to paint the wall? What are the advantages and disadvantages of colored latex paint for brushing the wall?

What are the steps of latex paint painting wall.

1. Grassroots treatment.

Before painting, it is necessary to do the base treatment, clean up the dust and other debris on it, and the pipelines on the wall should be closed.

2. Scrape the putty twice.

After the base layer is processed, take the jujube roll, start to apply the putty, must be scraped more than twice, use the horizontal way to apply the scrape, and ensure its flatness and uniformity, and the second time needs to wait for the first time to be completely dry before scraping. Wait until it is shaved and dry twice, then sand it and clean it clean.

3. Underlying processing.

Before the bottom layer of the wall is constructed, it needs to be kept dry and tidy, and then start spraying, just one pass. However, it is necessary to pay attention to the uniformity and not to miss the coating.

4. Middle-layer coating construction.

In the construction of the middle layer of paint, the wall needs to be uneven, and it is necessary to use putty to make up for it, and then polish it flat.

5. Spraying of latex paint surface layer.

After the construction of the middle layer is completed, the spraying of the surface layer of latex paint begins, which normally needs to be sprayed three times, and in the spraying process, it is necessary to ensure that all parts are sprayed, so that the effect will be beautiful.

6. Cleaning. Finally, after the above processes are completed, the cleaning work can begin. For example, remove the obscurations and clean them.

Advantages and disadvantages of colored latex paint for brushing walls.

1. There is a wide range to choose from.

There is a wide range of latex paints, it has many medium colors, and it can also be blended and used according to different needs. This can be especially used in various styles of decoration environments, and it is easy to dissipate the surplus.

2. It is easy to have color difference.

Although there are many colors of latex paint, each time the color is blended, it is easy to have the problem of color difference. If the first dosage is not well mastered, the second blending is required, then it is easy to have color difference. At the same time, after a long time of use, there is still a phenomenon of fading.

As we all know, the wall is an appearance project, the quality of its decoration can not only affect the beauty of the whole home, but also affect everyone's health, therefore, many people will choose more environmentally friendly latex paint when painting the wall, let's introduce it in detail: the steps of wall painting latex paint and the precautions for wall painting latex paint.

One: finished product protection.

First of all, it is necessary to maintain the maintenance of the other completed parts of the room.

Two: Preparation.

Before construction, it is necessary to remove the dust and other impurities on the surface, fill in the uneven places, and then apply a layer of interface agent on the wall.

Three: Yin and Yang angle straightening and bottom leveling.

After doing the preliminary work, we need to see if the wall is flat and check the verticality of the corners, so that we can confirm the construction plan.

Four: Scrape putty.

After doing the above work, we can start scraping the putty, and when brushing, we need to do it up to 3 times, so that we can match the leak to make it more beautiful.

Five: polish putty.

When sanding, we first illuminate the surface with a 200-watt bulb so that we can check the flatness of the manuscript as we go, so that we can achieve better results.

Six: Brush the primer.

After cleaning the float and sinking, we can brush the primer, when brushing, as long as the uniform brush once, after drying, in the next step.

Seven: Brush the top coat.

After the above steps are done, we can make the topcoat, in order to look good, we had better do it twice, and the second time should be more than 3 hours different from the previous time, and after it is completely dry, you can do waterproofing and other preventive measures.

Precautions for wall painting latex paint:

1. Prevent obvious whiskering.

During construction, it is necessary to adjust its concentration first, and then, when dipping and coating, it is necessary to sell an appropriate amount of leakage, and to smooth it several times during construction, so as to avoid excessive whiskering.

2. Prevent penetration.

In order to avoid the phenomenon of penetrating the bottom, then, it is not allowed to miss the brush during operation, and it is necessary to ensure its concentration, and not too much water can be added.

3. Prevent obvious joints.

In the operation, pay attention to the method, under normal circumstances, are the use of high and low brush, and the second row should be followed by the previous row, so as to avoid the obvious phenomenon of joints.

Step 1, first to buy the right painting tools and brushes, the best tools can brush out a thicker coating, so that the original bottom of the color can be covered, but also to ensure the durability of the paint film, can withstand repeated scrubbing.

Step 2: Before brushing latex paint, the joints should be repaired and leveled, and the dust and dirt on the wall should be removed with a special detergent or water for cleaning the wall or glass, and it should be dried. If there are holes such as nail holes on the wall, putty can be used to fill them.

Step 3, and then mix the latex paint with water, the proportion of water added to the roller coating is generally controlled to 20% to 30% according to the volume ratio is the appropriate proportion, if the water is too much, it is easy to cause the latex paint film formation is poor.

Step 4: Stir the paint and water evenly and then stand for 20 minutes to achieve the purpose of defoaming, so as to avoid needle holes or small bubbles after the latex paint is on the wall.

Step 5: The still time has passed. It's time to paint. Then moisten your tools with water first, such as the wool brush and roller in the corner of the shady corner, first moisten with water, and then dip the material. The next step is painting.

Step 6, the latex paint is painted according to the standard process, which is painted in a bottom-to-bottom and two-sided way.

1) The first brush primer plays a role in closing the alkalinity and increasing the mechanical occlusion (adhesion) of the bottom coat, and the painting process is the living room and then the bedroom, and the top plate (ceiling) and then the wall.

2) If you feel that the wall is not delicate enough, you can also use 600 water and sand to gently knock off some small particles on the wall before painting the second topcoat.

3) Paint again after 2 to 4 hours after each painting, or feel it with your fingers, if the paint you press with your fingers does not feel sticky (acupressure dry), then it means that you can paint.

4) The position of the switch box and door cover and window cover should be covered with masking paper before painting. Masking paper can be bought together when you buy a roller and a wool brush.

1. Deal with the base layer of the wall.

Different base treatment methods are slightly different, but the general requirement is that the base layer needs to be smooth and clean before painting. For the wall of the blank house, it is necessary to level and clean; For painting the wall, it is necessary to remove the old paint, and the putty needs to be removed after more than 5 years of use; For the original wallpapered wallpaper, tear off the wallpaper and then process.

2. Apply the interface agent.

After the basic cleaning treatment of the different wall base layers is done, the next step is to choose the brush interface agent. The interface agent can enhance the adhesion to the base layer and avoid the hollowing and shelling of the plastering layer. When brushing the interface agent, be sure to brush until it is evenly brushed.

3. Waterproof treatment.

If it is a wall that needs to be waterproofed such as kitchens and bathrooms, waterproof coatings must be used. In the past, waterproof materials only needed to be simply painted, but now the new waterproof coatings are mostly two-component or even three-component. Therefore, before construction, it is necessary to understand how to deploy and what the proportion of deployment is required.

If it is not proportionally blended, the waterproof coating may not achieve the original effect.

Fourth, anti-crack treatment.

If there are cracks in the wall, then the cracks need to be treated before painting. Under normal circumstances, it is necessary to paste kraft paper, good cloth, mesh fiber cloth, bandages and other materials on the cracks of the wall, the junction of the light wall and the load-bearing wall, and the joints of gypsum board.

Fifth, scrape putty.

After the wall is cleaned basically, brushed with interface agent, leveling, and anti-cracking treatment, the next step is to brush putty. Common putty powder needs to be blended on site, and the ratio of putty powder and water should be strictly controlled according to the product instructions when blending. At the same time, try to stir it well, and then let it stand for 10 to 20 minutes and stir it again before use.

When scraping the putty, use a scraper or spatula to scrape according to the conventional batch, and try to use as much force as possible to make it fully bonded to the wall, and do not scrape repeatedly in one step. The thickness of the batch scraping putty is generally in the middle, the number of scraping and coating should not be too much, the new house is generally approved twice, and the second-hand house is better to be approved three times. After each brushing, due to the high strength of the putty, the putty should be in a semi-dry state, and the scraper should be used to collect the light and level it when the putty is in a semi-dry state and is not deformed by hand.

6. Sandpaper sanding.

After the putty is dry, polish it with sandpaper, and the polishing must be operated from all sides to the center, and you should be extra careful when polishing the corners, so that you can be as straight as possible. Pay attention to the sandpaper do not miss the grinding or grind the putty through, after the scraper is sanded with sandpaper, the floating dust is cleaned up, and the topcoat can be directly brushed.

7. Brush the primer.

Nowadays, the wall generally needs to be painted with primer, which is used to seal the base layer, increase adhesion and improve fullness. The primer must be brushed evenly to ensure that every part of the wall is brushed, if the wall eats a large amount of paint, it is best to add a little more water to the primer to ensure that it can be painted evenly.

8. Paint the topcoat.

After the primer has dried, it needs to be sanded again. After that, it's time to apply the topcoat. Do not add too much water when mixing the topcoat, otherwise it will affect the thickness of the paint film, the feel and the hardness of the paint film. The topcoat is generally brushed twice.

1. Wall repair.

For the rough wall or the house that has made 1 putty layer, the base layer requires that the base layer must be flat and firm. There shall be no chalking, sanding, hollowing, falling off and other phenomena.

2. Scrape putty.

The effect of putty is to make the wall a little smoother.

3. Wall polishing.

After scraping putty, there are always some uneven surfaces, or the base layer is not very flat. At this time, sandpaper needs to be dispatched to carry out manual grinding and repair.

4. Paint operation.

Most of the construction methods of paint have four types: row brush, stick brush, spray gun, and batch. When spraying, the spray gun should be held steadily, and the distance between the nozzle and the wall should be 30-50 cm, not too close or too far. The spray gun moves regularly, and the horizontal and longitudinal S-shaped walls are painted.

In general, it should move at a constant speed between 400 and 600 mm per minute. It is necessary to pay attention to the consistent color and uniform thickness of the stubble parts, and to prevent leakage and flow.

Construction method: brushing, rolling, and spraying have their own lengths and disadvantages, and each should take what it needs.

Roller coating is suitable for large-area application, and the efficiency is higher than that of brushing, but there will be a fish skin effect like a hemp surface. This method of construction is unpopular for those who don't like hemp noodles. In addition, roller coating requires nearly 20% more material than brushing, artificially increasing the cost.

The brushing method is to paint manually with a brush, which is a commonly used construction method. The advantages of the brushing method are that it saves paint, the tool is simple, the construction is convenient, it is easy to master, the flexibility is strong and the adaptability to the paint variety is also strong, and it can be used for general paint.

However, the disadvantage of the brushing method is that the manual operation labor intensity is high, the efficiency is low, and it is not suitable for the quick-drying paint, if the operation is not skillful, the action is not agile, the paint film will produce brush marks, sagging, and the defects of uneven brushing.

There are two types of spraying, one is air spraying and the other is high-pressure airless spraying.

Air spraying will leave a lot of bubbles on the wall, although the construction speed is fast, the effect will be very poor, and it is not recommended to use it indoors.

High-pressure airless spraying has just become popular in China in recent years, but in foreign countries, high-pressure airless spraying interior and exterior wall latex paint has long been widely used. The specific construction method is to use a special high-pressure airless spraying machine to transport the high-pressure paint to the spray gun through the high-pressure hose, and release the pressure through the spray gun to form atomization, so as to form a smooth and dense coating on the surface of the wall.
