In home decoration, paint engineering occupies a very important part, the emergence of paint construction engineering has basically indicated that the decoration and more than half, the general paint construction process is for the interior surface to be more interesting, so what are the specific steps of the paint construction process.

When it comes to renovating a house, most of the owners leave it to the renovation company.

to decorate, which not only saves their own time, but also reduces some of the decoration troubles. Generally speaking, in home decoration, the paint project is generally the face of home decoration, if it is not done well, it will not only affect the quality of home decoration, but also leave many troubles to the owner, such as the appearance of paint loss, so in home decoration, what are the steps of the paint project?

1. Steps of painting project: preparation.

Before decoration, the construction personnel should prepare for painting in advance, generally including the cleaning of the paint environment, the protection measures of furniture, etc., such as the door and window frame is best pasted with a layer of color separation paper, and the furniture of wooden cabinets and partitions is best wrapped with a layer of newspaper, so as to avoid the situation that the paint drips on the surface of the furniture and is stained.

2. The steps of the paint project: color mixing.

In the home space area of the finish, first of all, calculate how much paint is needed to avoid the occurrence of insufficient paint or waste in the later stage, and then evenly allocate the required paint to prevent the surface of the furniture from being affected when painting, resulting in uniform color, and finally the primer is applied to avoid the texture of the furniture surface.

3. The steps of the painting project: construction.

If the owner has done the first two steps of the work, now officially entered the construction stage of painting, which is in the order of first hanging ceiling, lines, and then the wall. Generally speaking, it is necessary to repeat at least two times when painting the wall, but it is best to have a certain time interval between the two coats.

4. The steps of painting engineering: grinding.

After the painting is finished, in order to keep the wall smooth, we need to polish the wall, when the wall is sanded, we can touch the wall with our hands to see if the wall is smooth, and then use a softer putty.

Perform the process again, and then sweep the wall again.

5. Steps of painting project: cleaning.

After the construction personnel have completed the above steps, the owner can accept it, and during the acceptance, it is necessary to carefully check whether the wall and the surrounding area are clean and clean, and whether there are traces of paint in other places.

1) The original base layer of the old house must be removed (except for the new house and the intact old paint layer). Before scraping, check the original base with a 2m ruler, if the error exceeds 5, use talcum powder and white cement or gypsum powder to level it. (2) The base layer of gypsum board on the paper surface should be hooked with gypsum powder, and then attached with kraft paper or special bandages.

The special screws on the gypsum board must be repaired with anti-rust paint. (3) The base layer of the wood board must be brushed with alkyd varnish, hooked with wood glue powder or putty, and then pasted with kraft paper or special bandages, and shall not be blistered. (4) The first putty can be scraped with a ruler, and the yin and yang angles must be found by the ink line to find the verticality and flatness.

The latter putty should be completely dried before it can be constructed. (5) The second putty treatment of the wall, should achieve a large surface smooth, smooth, flatness with a 2-meter ruler to check, the large surface should be 3. 6) The third putty is a local patch, check the flatness with a 200 watt bulb or 800 iodine-tungsten lamp side illumination, and make up for it.

7) When scraping putty, try not to pollute other types of work, and keep the construction process and site clean. (8) When the paint construction personnel scrape ash at a high place, they should use stools and springboards, and it is strictly forbidden to step on the woodwork. Scaffolding is safe and reliable, and easy to use.

If the floor or floor tile has been constructed, the stool feet must be bandaged and protected before they can be used when the paint is re-applied. (9) Before the construction of the topcoat, the door edge, cabinet edge and other places at the junction with the latex paint should be protected with paper tape, and the floating ash on the wall should be cleaned before it can be carried out. (10) Latex paint construction primer once, topcoat twice.

After applying the primer, use the primer to adjust the putty to make up for it, and then apply the paint after sanding. (11) When painting, add water and stir evenly according to the actual situation, and add no more than 20% of water. (12) If the topcoat is brushed, it should be applied from top to bottom, first vertically and then horizontally, and finally gently comb the brush marks in the vertical direction.

The topcoat shall not be painted with obvious brush marks, and there shall be no flow phenomenon. Painting construction should be done from top to bottom, after the congenital flower wall, and the same area should be completed continuously. (13) If you need to pause during the painting process, you need to soak the brush or roller in the paint or water in time, wash all the utensils with water immediately after the brushing is completed, and dry them in the shade for later use.

14) The second topcoat should be carried out only after the previous topcoat is completely dry, at least two hours apart. The room temperature of latex paint construction should be above 10 degrees Celsius. At the same time, the doors and windows are closed to reduce air circulation, and the windows can be opened for ventilation only after 2 hours of painting.

15) When the latex paint is painted, other types of work shall not be constructed to prevent pollution. Pay attention to the protection of the finished product (ground and adjacent finished products). Latex paint that falls on other decorative finished products should be cleaned.

16) After the construction of latex paint, attention should be paid to the protection of the finished product, and no injuries should be hung, especially the light and mercerized latex paint should be paid more attention to, because the light and mercerized latex paint is easy to appear after brushing"Flowers"phenomenon.

How to make wall paint and its steps is a professional craft for the insider, and it is not so easy for the layman to do well.

Step 1: Apply the interface agent. Uses: Seal the base layer to prevent putty from having problems due to loose cement wall, floating soil or too dry, etc., and its surface is more suitable for putty adhesion than cement wall.

Step 2: Scrape putty. The flatness of the wall should be measured before scraping putty to determine the method to scrape putty.

Generally, the wall can be scraped with 2 putty, which can not only level but also cover the background color. Putty with poor flatness needs to be scraped several times 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.

The interval between each batch of putty scraping should be more than 2 hours (after the surface is dry).

Step 3: Sand the putty. Use a light bulb of 200 watts or more to light the wall and check the flatness while sanding.

Step 4: Brush the primer. After cleaning the dust on the surface of the sanded putty, the primer can be applied. The primer is applied once or twice, making sure that it is even, and after it dries thoroughly (2-4 hours), it can be sanded with fine sandpaper.

Step 5: Brush the topcoat. The topcoat is usually brushed twice, with an interval of more than 2-4 hours between each pass (depending on the drying time) and allowed to dry basically.

Wall solidification, leveling, putty, primer, wall paint.

Base treatment, full scraping putty on both sides, upper base coating, etc.

The specific construction process of latex paint is as follows:

1. First remove the ash blocks, scum and other debris on the decoration surface with a knife. After surface cleaning, the SG821 putty is adjusted to a suitable consistency with a dilution of water and vinyl acetate latex (with a mix ratio of 10:1), and the wall defects are filled with it.

After the putty is dry, first smooth the excess putty with a knife, and then polish it with coarse sandpaper.

2. Full scraping of putty twice: the first time the rubber scraper should be scraped, which requires the horizontal scraping to be smooth, uniform, smooth, dense and flat, and the line corners and edges are neat. Try to scrape as thin as possible, do not miss scrapes, do not leave joints, pay attention not to stain the door and window frames and other parts, otherwise it should be cleaned up in time.

After the first putty is dry, sand it with coarse sandpaper. Pay attention to the balance of the operation, protect the edges and corners, and clean it with a brown broom after grinding. The method of scraping putty for the second pass is the same as for the first pass, but the direction of scraping is perpendicular to the previous putty.

Then use coarse sandpaper to polish and flat, otherwise it must be carried out for the third and fourth times, and the 300w sun lamp side illumination wall or ceiling surface is polished and smoothed with coarse sandpaper, and finally polished with fine sandpaper to smooth and smooth.

3. Bottom coating: The construction should be carried out on a dry, clean and firm layer surface, sprayed once, and the coating should be uniform and not missed.

4. Middle-layer coating construction: If there is any unevenness before the first coating of the middle-layer coating, use putty to flatten and polish. The paint should be fully stirred with a portable electric mixer gun before use.

If the consistency is large, it can be diluted with water, but the amount of water added each time should be consistent, and the consistency should not be different. The paint is then poured into a tray and coated with a paint roller for the first time. The rollers should be painted transversely, and then rolled longitudinally, driving the paint away and flattening.

The rolling coating sequence is generally from top to bottom, from left to right, first far and then near, first the corners and corners, small surfaces and then large surfaces. The thickness is required to be uniform to prevent excessive coating from falling. The roller can not be applied to the corner of the shade, and it needs to be supplemented with a brush, and the coating should not be missed.

Always remove the roller hairs that stick to the wall. A wall should be built in one go. Avoid overlapping brushstrokes, and wipe the paint stained to other parts with water in time.

5. Latex paint surface layer spraying: due to the different base materials, tooth periods, alkalinity, and dryness, test spraying should be carried out on the local wall in advance to determine the compatibility of the base layer and the coating, and at the same time determine the appropriate coating amount. Before using the latex paint paint, shake the container enough to mix it well, then open the container and stir it well with a wooden stick.

When spraying, the mouth should always be perpendicular to the decorative table (especially in the dark corner), and the distance is about to be adjusted according to the size of the decoration surface), and the nozzle pressure is the spray gun in a Z-shaped shape, and the horizontal and longitudinal crossing. The movement of the spray gun should be balanced, and the coating amount should be consistent, and it should not stop and move from time to time, so as to avoid the phenomenon of stacking, sagging or missing spraying. In order to improve the spraying efficiency and quality, the spraying sequence should be safe

The order of the wall part, the column part, the pre-surface part, the door and window part, should be flexibly mastered, and the finished finish should not be affected without increasing repeated shading.

6. Cleaning: remove the obstruction and clean the splash material.

Generally speaking, the process flow of wall painting is: blank wall - grassroots cleaning - brushing 1 time interface agent - crack treatment - leveling (including yin and yang angle straightening) - sticking - scraping 2-3 times putty - grinding - primer - mending and polishing (the place to make up must be used primer 1 time) - two times topcoat - maintenance (the effect of protecting the wall) and other eight steps.

The coating base assembly project is one of the key projects of home decoration technology. If you want to achieve a generally satisfactory home décor effect, you should not let your guard down during construction! If a problem is found during construction, it should be considered immediatelyThe construction process of the wall painting processBefore applying wall paint, the primer should first be cleaned to remove debris and dust from the primer.

If the undercoat comes off or peels off, it must first be removed from the original wall**. If there are cracks in the wall, cover the space with kraft paper or mesh.

After cleaning the base layer, we can replace the chisel by applying an interface agent. After the application of the interface agent,The construction process of the wall painting process is:It can improve the adhesion of the base layer and can reduce the occurrence of hollowing on the wall surface.

When the wall is uneven, we must make the wall flat and fill the uneven place with plaster to ensure that the horizontal error of the wall is within 3 mm.

Once the walls are level, you can start scraping putty. For putty, it is better to choose a product with finer particles and a harder texture. Wall putty should generally be scraped two to three times.

The first layer of putty should be thicker. This is for a better leveling of the wall. The construction process of the wall painting process is:The second and third layers of the putty layer are relatively thin, and the paper makes the walls look softer.

Pay attention to the lotion when you scrape putty. After scraping putty, you have to wait until it is completely dry before you can scrape the putty again.

Many people don't understand the importance of polishing, but it is very important to have a perfect lacquer result. When sanding, the sandpaper chosen should be thin to avoid leaving marks on the walls. After polishing, clean the wall to prevent dust from affecting the adhesion of the paint.

Once sanding is complete, a primer can be used. When applying primer, make sure that all corners of the wall are evenly applied. The construction process of the wall painting process is:You can add a small amount of water to the paint to ensure that the primer is applied evenly.

After the primer is applied, sometimes some imperfections are left during the polishing process that are easy to find after the primer has been applied. When these problems arise on the wall, we need to work on the wall. Sandpaper the walls and reapply the primer.

When painting the topcoat, be sure to follow the product requirementsThe construction process of the wall painting process is:In order not to affect the effect of the paint film, pay attention to the brush corners, seams, etc., to ensure that a uniform coating is not missed. The top layer usually needs to be applied twice. During construction, attention should be paid to the temperature of the construction site.

That's all about:The construction process of the wall painting process is:Some information on what, I hope it will be useful to you.
