Q: How many processes do you need to brush the paint?

1.Choose coatings with excellent performance.

When choosing coatings, we should be clear about what requirements we want to achieve when choosing coatings, such as water resistance, high gloss, don't blindly choose, there is also a big gap in the types of water-based coatings.

Shuaike chemical interior wall coating resin.

2. Estimate the dosage before buying paint.

Many consumers do not estimate the amount of paint used in advance, for fear of buying less paint, and always buy more when purchasing. This may cause a waste of materials, increase the cost of home improvement, and at the same time, the accumulation of too much paint will also have a certain impact on construction safety. Therefore, it is recommended that consumers must look at the area of the construction area before construction, so as to estimate the amount of materials purchased.

3. The construction preparation process needs to be done well.

Water-based building exterior wall paint resin.

Paint dripping will stain the furniture during construction, so paste color separation paper at the junction of doors, window frames and furniture before painting to protect it from dripping paint that is difficult to clean.

4. Wall paint construction tips.

Different tools will bring different effects, for example, the roller brush is divided into two kinds of thickness, and the bristles are also different from wool and chemical fiber, and the painting effect of different brushes varies greatly.

First scrape putty, then brush the paint, paint at least 2 times, the specific number of times according to the use of different paint and paint types and walls.

Under normal circumstances, the walls must be painted 3 times, and the actual effect is good. Because the first time is the inner layer, the second time is covering, and the third time is the surface ground leveling, the actual effect is very good. In addition to this, the paint coating is mainly light and symmetrical.

Otherwise, there will be ripples, but the adverse effects will not be happy. At the same time, it should be noted that the frequency of painting should be determined according to the height of the color and the area covered, rather than the more painting frequency, the better. Because the paint is painted too often, after the wall is dried, the paint is very easy to crack and fall off under the action of weathering.

Brush the first paint: the order of painting is to brush the cast-in-place board, and then brush the wall, and the wall is from top to bottom. Clean the walls first, take a cloth and wipe the dust off the walls.

With a signature brush. When applying a new pen, remove wavy and unstable hair from the pen. Mix the paint well before application and dilute it with the right amount of water to avoid brushing the first coat of paint.

Add putty powder after drying, polish with an abrasive cloth, and rinse neatly after drying.

Brush the paint for the second time: the actual operation needs to be the same as the first time. Mix well before application. If it is not thick, it is not suitable to drain water to avoid seepage at the bottom end. After the paint layer is dry, use sandpaper to polish off the small bumps and brushes on the wall, and clean them after polishing.

The decoration of the new house generally must be brushed once and twice painted, the old house renovation if you do not shovel the wall and scrape putty again, then immediately brush the paint twice, especially in the case of winter, pay attention to the ambient temperature of the substrate is less than 5 degrees, and the construction can not be carried out, which will endanger the time of the paint coating film. Too hot, too cold, too wet, cold is not suitable.

Wall latex paint is not considered several times, but to the best practical effect to calculate, there are some old walls because of the bottom alkali or damp, the first to do waterproof material plating solution, then it must be twice, plus the bottom putty powder is not counted, the surface architectural paint depends on the situation, if the yellowing situation must be brushed with anti-alkali sealing primer twice, if there is no potential safety hazard can be exempted from this process, as far as paint is concerned, generally must be brushed at least twice to achieve the compactness and uniformity of architectural coatings, At this time, if you change to painting work, because the paint coating is thicker, you can achieve the effect at one time!

Generally, when decorating and painting the wall, the wall should be painted at least twice, but it must be dried before brushing the next time, otherwise it will crack; First of all, keep the wall dry, the surface moisture should be less than 6%, the pH value should be less than 9, the second is to clean the wall, and then paint, and wait until the first paint is dry before brushing the next time.

I think that if you are decorating and painting the wall, the wall should be coated with at least 5 layers of paint; First of all, the wall must be treated first, if the wall is very uneven, it is necessary to spray a layer of paint first, and then apply putty three times, after applying putty, and then carry out a other paint on the wall as a whole to smooth and wipe evenly.

Brush paint to 2 times, first of all, the primer must not be forgotten, the next is the topcoat, the construction of the topcoat should start from the chandelier, then the wall, the paint on the wall also needs to be at least twice, all over to add water to facilitate the absorption of the paint on the wall, the second time do not add water to supplement the absorbed paint.

Paint brushing process method: There are six kinds of coating spraying methods: brushing, wiping, painting, painting, roller coating and spraying process. Brushing is a method of scraping thick architectural coatings with a scraper.

Previously, it was used as oil-soluble topcoat, sizing lacquer, alkyd varnish, etc. In post-modern furniture and home decoration work, brushing is mostly used to scrape putty powder.

or fillers. Rubbing refers to using raw materials with good oil absorption such as rags, cotton fibers, and yarn as coating tools, and taking a certain amount of scraping raw materials and evenly applying them to the surface of the coated wood to achieve the purpose of filling holes and coloring. At this stage, it is generally used in coloring processing processes such as colored plate sealant, wood texture treasure and Grace.

The painting should be done by hand with a brush as a painting tool.

Lacquering is a method in which architectural coatings or additives are evenly applied to the surface of an object to produce a uniform and flat coating. Roller coating is a spraying method carried out by rollers or rollers of mechanical equipment, and it is only suitable for the floor plan of the object.

Spraying, rock color stone such as man-made plates.

Thick cardboard, walls, etc., mainly used in spraying buildings, boats, cars, walls, etc.

The spraying process is a spraying method in which all the coated material is immersed in a container filled with paint, and then removed from the tank in a short period of time, and the excess coating liquid is re-flowed back to the tank. Coating is the use of architectural paint viscous spraying method, the architectural paint into a certain width of the prologue shape, constantly falling out from the top, at the bottom, by the conveyor belt to transport the coated object under the paint curtain according to the spraying, the architectural paint that has not been sprayed on the surface of the coated object can be retrieved, assisted by the pump circulation system.

Therefore, the consumption of architectural coatings is small.

Attention needs to be paid to the paint brushing process: when the wall is brushed and the painted wall is checked, you can use the back of your hand to rub the wall continuously, and if you feel smooth and smooth, it means that the time is in place. If you feel astringent to the touch, and then look at the wall from the backlight position, if the surface layer is uneven, there are obvious traces of the barrel walking, indicating that in the construction process, the number of times the wall is painted is far from enough, and the thickness of the architectural paint layer does not meet the requirements.

Normal brushing should be carried out once and twice the steps of painting, and everything is shoddy from the flatness of the surface.

Express it. Qualified engineering projects will look very symmetrical under the backlight, and no traces of the roller brush can be seen.

There are several processes involved in exterior wall paint painting

1. Check the condition of the wall substrate first; 2. Clean the base layer of the wall; 3. Treat holes and cracks in the wall; 4. Scrape 1-2 layers of putty on the exterior wall according to the situation; 5. Roller coating alkali-resistant sealing primer; 6. Roller coating varnish; 7. Polishing corners and rough parts; 8. Spraying exterior wall paint; 9. Paste tape into grids at the elastic line part; 10. Elastic wire according to size requirements.

What are the types of exterior paints

1. Real stone paint.

Real stone paint is mainly made of natural stone crushed particles, and real stone paint is mainly divided into single color or colorful. Real stone paint is the preferred material for the exterior walls of many high-end buildings, which has the characteristics of safety, good decoration and high cost performance. The building has a natural and authentic color, giving people an elegant and harmonious aesthetic.

2. Exterior wall latex paint.

Latex paint is a water-based paint made of aqueous polymer solution, which is generally used on exterior walls, but can also be used in wet places such as toilets. Exterior wall paint has functions such as anti-aging and color retention.

3. Imitation stone paint.

The decorative effect of imitation stone paint is very similar to that of marble and granite, and it is prepared with natural stone powder of various colors. Imitation stone paint is a kind of paint that is more difficult to make in art paints, in addition to the hardness is not as good as natural stone, both the texture and color are close to natural stone.

4. Wood grain paint.

Wood grain paint is a water-based environmentally friendly paint that imitates wood texture, which can be matched with colored primer to realistically imitate various effects, which can be comparable to log furniture. It is mainly through a similar way of water transfer hall tung printing, and the imitation wood grain paint is transferred to the substrate to be constructed.

I concluded: The above is about the relevant content of how many processes there are in exterior wall paint painting, I believe everyone understands it! There are many steps and suddenness in exterior wall paint painting, so when painting exterior wall paint, you must follow these steps, and there are many types of exterior wall paint, which can be selected according to your own needs.

The house painting should go through 8 processes, and the following points should be paid attention to:

1. Deal with the base layer of the wall. Be cautious before painting, and the base layer should be smooth and clean. For the wall of the blank house, it is necessary to carry out leveling and cleaning; For painting walls, it is necessary to remove the old paint, and the putty needs to be removed after more than 5 years of use.

2. Apply the 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. For walls that have waterproof needs such as kitchens and bathrooms, waterproof coatings should be used.

Fourth, anti-crack treatment. If there are cracks in the wall, the cracks need to be repaired. It is necessary to paste kraft paper, good cloth, mesh fiber cloth, bandages and other materials on the cracks in 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. 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 close the light and level when the putty is in a semi-dry state.

6. Sandpaper sanding. After the putty is dry, it is necessary to polish it with sandpaper, and the grinding must be operated from all sides to the center, pay attention to polishing the filial piety sandpaper and do not miss the grinding or grind the putty through, and the scraper is printed after the sandpaper is polished, and the floating dust should be cleaned up.

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.

8. Paint the topcoat. Once the primer is dry, it needs to be sanded again. After that, the topcoat is applied, and the topcoat is usually brushed twice.

Normal wall painting has to go through four processes: putty, leveling, grinding and painting, and the painting can be subdivided into the process of priming once and topcoat twice.

Precautions: 1. After the wall is painted, when checking the painted wall, rub the back of your hand on the wall repeatedly, and feel smooth and smooth. If the hand feels very astringent to the touch, and then looks at the wall from the backlit direction, if the surface is uneven, there are obvious traces of the roller walking, indicating that in the construction process, the number of times the wall is painted is not enough, and the thickness of the paint layer does not meet the requirements, then rectification is required.

2. If it is decorated in summer, it is best to dehumidify the room first, or use desiccant such as quicklime to adjust the air humidity, and try to use moisture-proof materials and moisture-proof processes, such as Hexiang board and ecological board with good waterproofness. At the same time, pay attention to the use of edge banding and painting process to reduce the impact of air humidity on decoration quality.

3. In humid weather, it is best not to rush to carry out the painting process of wall paint and paint, otherwise it is easy to crack, deteriorate or mildew and turn yellow. Especially when the air humidity is greater than 80%, the use of plaster, putty, latex paint, paint and any paint should be avoided as much as possible during the decoration process.

Exterior wall paint is not only colorful, but also its water resistance, pollution resistance and weather resistance are also very good, so now it is more and more liked by the majority of consumers. The construction process mainly includes the following processes: 1. Inspection and recording of the wall substrate; 2. Clean the wall foundation; 3. Deal with wall holes, cracks, etc.; 4. Scrape 1-2 layers of putty on the exterior wall according to the situation; 5. Roller coating alkali-resistant sealing primer; 6. Roller coating varnish; 7. Polishing corners and rough parts; 8. Spraying exterior wall paint; 9. Paste tape into grids at the elastic line part; 10. Elastic wire according to size requirements.

House painting is actually very simple, the first part: scraping putty, mainly leveling. It is better to have the oiler shine on the lamp.

The second part: brush the primer, the main purpose of brushing the primer is to cover the putty, so that the primer can penetrate into the putty and play a role in sealing. Part 3:

Brush the top coat and adjust the color. It mainly plays the role of decoration. You can use roller coating or spraying, depending on your preference.

Roll coating fee of 20% of the lacquer).

The first step is to scrape putty leveling, generally the whole house is scraped twice, and then minor repairs and repairs again, in total, three times. Be sure to pay attention to the fact that each pass must be dry before you can scrape it again. The second step is to brush the primer, usually once.

The third step is to brush the topcoat, which can be toned according to your preferences, and the wide variety of products that are often seen on advertisements are basically topcoats. Generally, the topcoat is applied twice. Anyway, it should be noted that it must be dried thoroughly between each pass, otherwise it is easy to have problems such as resurgence in the future.
