The process of brushing latex paint, how long does it take to latex paint, there are several 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.

The process of brushing latex paint: base treatment, repair putty, scrape putty, apply the first latex paint, apply the second latex paint, apply the third latex paint.

1. Treatment of the wall base: The treatment methods of different base layers are slightly different, but the general requirement is that the base layer needs to be smooth and clean before painting.

<>3. Scraping putty: It refers to the most important step in the treatment of the base layer by filling or overall treatment to remove the uneven part of the surface of the base layer and keep the wall smooth and smooth.

4. Apply the first latex paint paint: the application sequence is to brush the top plate first and then the wall, and the wall should be up and then down when brushing the wall.

5. Apply the second pass of latex paint: the operation requirements are the same as the first pass, and it should be fully stirred before use.

6. Apply the third pass of latex paint: the operation requirements are the same as the second pass of latex paint. Because the latex paint film dries quickly, it should be operated continuously and quickly, starting from one end and gradually brushing to the other end, paying attention to the connection between the upper and lower brushes, and the latter row of pens is immediately followed by the previous row of pens to avoid drying and then dealing with the joints.

Introduction to latex paint

It is a kind of water-based coating prepared by adding pigments, fillers and various additives to synthetic resin emulsion as the base material, also known as synthetic resin emulsion coating, which is a kind of organic coating.

The color of latex paint is soft, the surface is smooth and smooth, and the appearance is fashionable and high-end, which is an ideal paint for painting walls. Latex paint dries quickly and has good alkali resistance, which is the first choice for many household coatings. So what are the construction processes of the latex paint process?

1. Clean up the bottom layer first, check the original bottom layer before scraping the ash, if it exceeds 5, then you need to use talcum powder and white cement or gypsum powder to level it.

2. The bottom layer of gypsum board on the paper surface is hooked with gypsum powder.

3. Brush the bottom layer of the laminate with alkyd varnish, and use wood glue powder or putty to hook the joints.

4. The first putty can be scraped by a ruler, and the yin and yang angles need to be used to find the verticality and flatness through the elastic ink line.

5. Slow down the spine After the first putty is completely dry, you can carry out the second putty.

6. Next, perform the third putty. 8

7. Remove the floating ash from the wall, and then apply the primer.

8. After the primer is dry, you can paint it, the primer once, and the topcoat twice.

What should be paid attention to in the construction of latex paint.

1. The wall must be dry, usually the new house should be naturally dried for more than two weeks, and the concrete wall should be naturally dried for more than three weeks, and the moisture content of the wall should be less than 10%.

2. The paint should be stored in a cool and dry place above 0.

3. The amount of water added should refer to the relevant instructions of the product as much as possible, and too much water will affect the gloss, hiding power, film formation and durability of the coating.

4. The construction should be stopped when the temperature is below 5, the construction should be stopped when the air humidity is too large, and the construction is strictly prohibited below 0.

5. The construction of the exterior wall should be stopped in case of rain, and if it rains within 12 hours after the end of construction, it should be shielded as much as possible to avoid the coating of the royal layer being affected.

Article summary: The above is the construction process of the latex paint process and what should be paid attention to in the construction of latex paint, I hope to help some friends in need.

The process and process of brushing latex paint: wall treatment, wall sealing, corner treatment, wall leveling, scraping putty paste, grinding the wall, painting primer, finding unevenness, and maintaining.

1. Wall treatment

The wall should be clean and flat, of course, in the wall treatment, you can use a slight moisturizing water to do an experiment to check whether the adhesion of the original coating is qualified, if there are some debris such as ash blocks, scum and so on, it should be removed with a knife.

2. Wall sealing

The wall is closed with 801 glue, the purpose of which is to enhance the adhesion between the putty and the wall. Of course, if it is an old house, then you can brush the interface agent to increase the insurance coefficient.

3. Yin angle treatment

When dealing with the elastic line of the wall Yin Pei Dan or the two corners, it is necessary to pay attention to its verticality; Under normal circumstances, the yang angle treatment can be done with a rod, and then the gypsum powder and 801 glue are used to prepare gypsum putty. In general, it is not recommended to use plaster lines.

4. Wall leveling

Check whether the wall has a "hollow drum", which can be judged by tapping, and its sound can be judged; Then use a slightly longer aluminum alloy ruler to check the depression of the top and the wall, make a mark, and use gypsum putty to pad the uneven wall, usually the uneven difference is not more than centimeter.

5. Scrape putty paste

The commonly used accessories for scraping putty brush latex paint are: waterproof putty, sandpaper, 801 glue, interface agent, gypsum putty and so on. After the plaster putty is dry, (each time it must be thoroughly dried), then scrape the putty.

There are two ways to test whether the putty is dry: to see if the color is consistent; Second, there is no phenomenon of "sticking sandpaper" when grinding.

6. Polishing the wall

The top surface of the strong light oblique can be sanded with No. 360 sandpaper, and the finer sandpaper is preferred, if the sandpaper is too thick, it will leave deep sand marks, and the paint will not be covered by coarseness. After sanding, the wall must be thoroughly cleaned to avoid dust that will affect the adhesion of the paint.

7. Apply primer

After the wall floating ash is cleaned, you can paint the first wall paint, and the compatibility of the primer must be brushed evenly, and every place must be brushed, and it is usually added a little more water when brushing the primer to ensure that it can be painted evenly.

8. Make up for injustices

In the putty grinding, the wall will leave some pit eye defects, usually it is difficult to see clearly with the naked eye, only after brushing the paint will be obvious, then it is necessary to make up, it must be polished and smoothed when paying attention to the repair, and then add a little more water to brush the primer again, so as not to make the color difference between the paint and the amount of water on other walls.

9. Carry out maintenance

Normally, although the latex paint will dry after 4 hours after painting, the dry paint film does not reach the standard hardness, so it is necessary to do wall care for 7 to 10 days without scrubbing or touching the wall.

The process and process of brushing latex paint are as follows:1Prepare tools and materials:

Latex paint, brushes, rollers, tarpaulins, brooms, detergents, buckets, etc. 2.Cleaning the walls:

Clean the walls with detergent and water to remove dust, oil, and other stains. 3.Pre-treatment of walls:

If there are cracks or uneven places on the wall, they need to be repaired and sanded first to ensure that the wall pins are flat. 4.Apply the primer:

Apply a primer to the wall to enhance the adhesion and hiding power of the latex paint. 5.Painted with latex paint:

Use a brush or roller to evenly apply the latex paint to the wall, being careful not to miss or repeat the brush. 6.Wait for drying:

Wait for the latex paint to dry, which usually takes about 24 hours. 7.Secondary brushing:

If desired, it can be covered for a second application to enhance the coverage and aesthetics of the coating. 8.Cleanup Tools:

Wash brushes, rollers, and other tools with water and detergent so that they can be used next time. The above is the process and process of brushing latex paint, it should be noted that when painting latex paint, we should pay attention to the thickness and uniformity of the brushing to ensure the quality and aesthetics of the coating.

The production process of ordinary latex knee is as follows:

1) water (it is best to use deionized water, groundwater can not be used) and a variety of additives 5 including dispersant, wetting agent, leveling agent, anticorrosive and mildew inhibitor, film-forming auxiliary, buffer, defoamer, rust inhibitor, whitening agent and other 6 mixed, and low-speed stirring;

2) Add white pigment filler (solid powder) and hydroxyethyl cellulose (789) aqueous solution for high-speed dispersion, and grind to make white pulp if necessary;

3) Add the white slurry to the emulsion slowly in batches, and then add the next batch of white slurry after stirring evenly at low speed, and then continue to stir at low speed to obtain the initial coating.

4) Adjust the viscosity of the initial paint with a thickener, mix the color and depth of the initial paint with a color paste, or add some defoamer to be the finished product of latex paint, which can be put into storage or sold after passing the filtering, weighing, packaging and inspection.

Generally speaking, the production process of latex paint includes the dispersion of pigments and fillers, the modulation, color matching, filtration and filling of latex paint.

At present, the process mode of the latex paint professional production plant is roughly like this, using a car tanker to send the emulsion, titanium dioxide and bulk seasoning into the factory, and using a pump to send it to the storage tank and powder silo. When batching, water and additives are added, and the titanium dioxide slurry and filler are sent to the high-speed disperser through the metering device with pumps and other conveying equipment, and the dispersion operation is carried out with the high-speed gear. After the dispersion operation is completed, the speed is reduced, the emulsion is pumped to the high-speed disperser through the flow meter, and other additives are added, and stirred evenly, so that the preparation is often white latex paint and base paint.

After passing the inspection, the white emulsion paint and base paint are sent to the storage tank for filling and color matching.

Generally, latex paint is completed in the following steps:

1. Beat and disperse, and put water, additives, and pigments and fillers into the dispersion tank in order for high-speed dispersion for 20-30 minutes.

2. If the process requires sanding to achieve the fineness of use, it will be sanded. After reaching the specified fineness, move on to the next process.

3. In the painting mixing stage, emulsion, defoamer, thickener (need to be diluted according to the product manual or engineer's instructions) and so on are added in turn.

4. Sampling inspection, factory inspection according to different types of products. (Type inspection is also required once a year or when the main raw materials are replaced, so as to ensure product quality).

5. Filter packaging after qualification.

The process and inspection items of different formulas are also different, so the specific process should be formulated by engineers. The above is just an approximate process.

Construction process: sweep the base layer to fill the putty, scrape the putty locally, grind the first full scraping putty, grind the second full scraping putty, grind the sealing primer paint the first coating, refill the putty, grind the second coating, polish and work.

Which is better, stronger adhesion between latex paint, wall handmade paint and machine paint? Teacher, please.

1. First of all, the foundation mortar is chiseled and decontaminated; 2. Scrape putty powder (generally three times); 3. Painting of basic coatings; 4. Painting of middle coatings; Finally, the painting of the top coat is painted. Generally, you can move in after 20-30 days of paint application and indoor ventilation.

1.Process flow: clean the wall, repair the wall, scrape putty, brush the first latex paint, brush the second latex paint, brush the third latex paint.

2.Clean the wall: Remove the peeling and loose parts of the wall, and use cement mortar to repair it, shovel the residual ash clean, and then sweep the wall.

4.Scraping putty: The number of times of scraping putty can be determined by the flatness of the wall, generally three times, polyvinyl acetate emulsion for kitchen, toilet and bathroom

Cement:water = 1:5:

1. Water-resistant putty. The first time with a rubber scraper transverse full scrape, a scraper followed by a scraper, the joint shall not be left behind, each scraper at the end of the end to be clean and neat. After drying, sandpaper, polish the floating putty and stains, and then clean the wall.

The second time with a rubber scraper vertical full scrape, the materials and methods used are the same as the first putty, after drying, the sandpaper is smoothed and cleaned. The third time use a rubber scraper to find the putty or scrape the putty with a steel scraper, scrape the wall flat, and then smooth and polish it with fine sandpaper after drying, and the putty shall not be omitted or worn through.

5.Brush the first latex paint: the painting sequence is to brush the top plate first and then the wall, and the wall is up and then down.

Clean the wall first, and use a cloth to wipe off the dust on the wall. The latex paint is painted with a pen, and when you use a new pen, remove the floating hairs and unstable hairs on the pen. Latex paint should be stirred evenly before use, and diluted with water appropriately to prevent the paint from not opening all over the head.

After drying, the putty is replenished, and then dried and polished with sandpaper and cleaned.

6.Brush the second time latex paint: the operation requirements are the same as the first time, fully stir before use, if it is not very thick, it is not appropriate to add water to prevent penetration. After the paint film is dried, use fine sandpaper to polish off the small bumps on the wall and the brush bristles, and clean them after grinding them smooth.

7.Brush the third latex paint: the method is the same as the second latex paint. Due to the rapid drying of the latex paint film, it should be operated continuously and quickly, starting from one end and gradually brushing to the other end, and the upper and lower brushes should be connected with each other, and the latter row of pens should be followed by the previous row of pens to avoid the appearance of dry rear joints.
