Is it better to spray or roller brush?

Well, latex paint is better to spray or brush, I think latex paint is sprayed well, sprayed very evenly. He will brush it when it is not so even, and sometimes he will have rice when it is not so even. So I said that I renovated the house last year, this latex paint I used to spray ah, sprayed latex paint sprayed very well, I think the house sprayed this latex paint, there are not only apples but also refining such decoration house standards.

It is satisfying, so everyone must spray latex paint when they want to spray it. Ah, don't use a rolling brush to roll a rolling brush, we used to decorate the house. Uh, the old way, well, there is no such thing as spray paint spraying, so everyone must pay attention.

Be sure to spray it when you use latex paint, and the spray is particularly even. Extraordinarily shiny. I went to the one who uh didn't decorate the house, and I didn't feel that way.

Ah, because I wasn't very proficient in decorating in the past. Well, after this experience, well, I suggest that when you decorate the house, you must use latex paint spray.

Latex paint is sprayed well.

The advantages of latex paint spraying are as follows:

1. Excellent surface quality. The paint sprayed on the wall forms a smooth, dense coating with no brush marks, which is incomparable to brushing and rolling.

2. High coating efficiency. The spraying efficiency of a single person is up to 350-550 square meters per hour, which is 10-16 times that of manual brushing.

3. Delay the life of the coating. High-pressure airless spraying, which uses high-pressure jet atomization, so that the paint particles can obtain strong kinetic energy to penetrate into the pores of the wall, so that the paint film and the wall form a mechanical occlusion, enhance the adhesion of the coating, and prolong the life.

4. The thickness of brush coating and roller coating is extremely uneven, generally between 35-200 microns, and the utilization rate is low. The airless spray coating has a uniform thickness, with a thickness of about 35 microns, and the utilization rate is high.

It should be a good one to spray, the main one is that the spray is relatively smooth and clean, the other is to spray more material-saving, etc., of course, the spray is also more labor-saving and time-saving, in general, the spray is better.

First, for example, the conditions of wall construction, you can refer to "I don't know how to do it, directly criticize putty, all cracked, of course, the local tyrant can be at will, no need to look, as long as there is money in the decoration, our number will be done in vain."

Second, under what circumstances do you need to hang the net of the whole house, which requires the experience and dedication of the workers, if they are all sand-gray walls, relatively loose, and the shovel can not be shoveled, it is best to hang the net of the whole house at this time.

3. When do you need to use plaster? This is a must for almost every construction site. The rough house may be very flat, but once you want to do a plane, it may be a few centimeters from one point to another, if the difference is four or five centimeters, you can't use putty to scrape directly, 100% will crack in the later stage, hollow, until a large area falls off, so the general construction site can not be directly satisfied with putty, if you do this, you are basically novices, or casual passers-by, do the money and leave.

Fourth, when to brush glue or interface agent or wall solid. Note here that the functions of the three things are the same, but the names are different. Some people like face, so if they have money, they will use the wall to fix it.

Remember, you must remove the original plain gray or white wall, and brush it when you do the wall, instead of not even shoveling the plain gray and white wall, and brush it directly, only looking good on the surface, in fact, it is to use fake professional to fool the real quality. Remember, renovation is not about face, it's about quality. Buy a toilet at a price, let's not learn from the local tyrants to brush the ground solidly, people use your love of face to make money, you are stupid. Five.

Which one is good and which is not good, it depends on whether the operator is very skilled, and whether the operator has a correct attitude. It is troublesome to use rollers, you need to brush more than once, and it is much easier to use a spray gun to see whether it is uniform or uneven. Now for the sake of work efficiency, many of them use spray guns, but three years ago when my home was renovated, they still use rollers, which are good!

Nowadays, a lot of it is spray painted.

Latex paint sprays better than roller brushes.

Spraying latex paint is very fast, and spraying latex paint can cover a large area of the wall faster than rolling latex paint. The spraying machine can complete the spraying of a large area in a short time, so the construction speed is faster, which can save time and labor costs. Spring Ridge.

Spraying latex paint can also avoid problems such as brush marks and missing corners, and the coating is more uniform and smooth, and the effect is more beautiful. At the same time, spraying latex paint can be used to treat complex surfaces, such as uneven walls, windows, doors, etc., which can ensure the quality and aesthetics of the coating.

Spraying latex paint can accurately control the amount of spraying, which can save paint more and reduce construction costs. Spraying latex paint can adjust the thickness of the coating according to needs, which can achieve different effects, and can also reduce the labor intensity of workers and improve construction efficiency.

Roller brush latex paint is slower to apply and takes a long time to complete a large area of painting. This will not only increase the construction time and labor cost, but also easily cause problems such as uneven brushing and missing coating at the corners and corners, which will affect the quality and aesthetics of the coating. It is difficult to control the thickness of roller brush latex paint, and it is easy to have uneven coating thickness, which affects the quality and aesthetics of the coating.

In addition, too thick coating thickness can easily lead to slow drying of the paint surface, which affects the construction progress.

Latex paint spraying features

Spraying for the technical requirements and equipment requirements of workers is very high, so the cost of spraying is relatively higher, and roller coating is relatively simple and much easier, so in this process can save a lot of costs, of course, roller coating is also a test of the worker's craftsmanship, if the craft or seepage is not good, the effect of roller coating is very poor, so if you want to choose roller coating, then you have to find a reliable worker.

Spraying is divided into two kinds of air spray and airless spraying, the main tool used is the spray gun, the use of the spray gun can be sprayed directly on the wall, but in the construction of the need to hold the spray gun steadily, otherwise it is easy to spray crooked or uneven, and the nozzle should be perpendicular to the wall, so the technical requirements are relatively high.

If it is a large area of latex paint, it is necessary to use airless spraying, which not only saves the material but also speeds up the construction period and is uniform, and the small area can only use the roller, as for the effect, there is no difference.

Generally, latex paint sales stores can provide free airless spraying services, because airless spraying is fast and about 20% more latex paint is used than roller roller coating, which is more expensive but has a better effect.

Roller coating saves paint, but now the cost of rework for workers is increasing year by year, mainly to calculate the final economic account, in principle, it should save money than airless spraying, but the effect is slightly worse, especially when encountering unfamiliar workers, the effect is not guaranteed.

Advantages of latex paint

1. It is safe, non-toxic and tasteless, which completely solves the labor protection and environmental pollution problems caused by the volatilization of toxic gases of organic solvents in painters, and fundamentally eliminates the danger of fire.

2. It is convenient to repent, and it can be brushed or rolled, sprayed, smeared, scraped, etc., and the construction tools can be cleaned with water.

3. The coating dries quickly and can be applied in one day.

Two or three roads, so the construction efficiency is high and the cost is low.

4. Good color retention and weather resistance, most exterior wall latex white paint is not easy to yellow, and the weather resistance can reach more than 10 years.

5. Good air permeability and strong alkali resistance, so when the humidity difference between the inside and outside of the coating is large, it is not easy to blister, and the coating is not easy to sweat indoors, especially suitable for painting on the cement surface and plaster surface of the internal and external walls of the building.

The latex paint roller brush manuscript is better.

Latex paint spraying method, it requires a relatively high technical level and equipment, so the cost is high, and some environmental restrictions are not conducive to spraying construction, it is easy to cause decoration damage, and it is more convenient to grind. The roller coating method, because it is manually operated, can save costs, but it needs to combine the craftsmanship of the workers, so the trembling bucket only needs a very professional construction worker.

Compared with the spraying method and the roller brush method, the spraying method is sprayed by a spray gun and controlled by the machine during construction, so the paint film will be relatively thin, and several painting processes are required to achieve better results, so it is more expensive to paint. Later maintenance is also more troublesome, and it is easy to cause large color difference. The roller brush method is different, it is more economical than spraying paint, and it is easier to repair later.

How to deal with latex paint wall soil.

1. Multi-functional cleaner: If you have a multi-functional cleaner at home, you can dilute it and spray it on a rag to wipe the tea stains on the wall.

2. Gypsum or precipitated calcium powder: If the wall is seriously dirty, use gypsum or precipitated calcium powder to rub on the cloth. Or use a fine sandpaper to wipe it off. Squeeze some toothpaste on a damp cloth to wipe off the pencil or colored crayon on the wall.

3. Cleaning with a damp cloth or toothpaste: depending on the quality of the latex paint used, the stains and light scratches of the good paint can be removed with a wet cloth and detergent, or wiped with toothpaste and water and a towel.

4. Sandpaper sanding: Slight latex paint wall stains can be sanded with fine sandpaper, scraped off a thin layer, and then painted with white shoe polish. Eraser:

Mild stains on the white wall can be gently wiped off with a clean white rag dipped in water, or you can use an eraser to try to wipe it, and the force must be gentle.

5. All kinds of detergents: the coating film of latex paint on the wall is very thin, the surface strength is not high, it is easy to be bumped and damaged by hard objects such as tables and chairs, and it is easy to be polluted by domestic stains.
