What's the difference between painting and painting? Is it better to paint or spray paint the wall?

When decorating the walls, we need to paint them. Common painting methods are painting and painting. How to choose? Next, Bian Xiao will tell you the difference between painting and not painting, whether the wall is painted or not.

1. What's the difference between painting and painting?

1. Painting Now most people will choose this construction method. The advantages of spray painting are: fast construction speed, good wall smoothness, good hand feeling and good texture. The disadvantages of spray painting are: a large amount of paint falls off, and the later maintenance is troublesome, because workers can't pull the spray painting machine to repair it in the later maintenance, so they can only brush it with a brush, and the texture of the brush is definitely different from that of spray painting.

2. The painting will be cheaper, but the construction will be slower. If you calculate your salary by the number of days, it is actually similar to painting. However, the paint surface has the texture and pattern of roller coating, which is convenient for maintenance. The disadvantage of painting is that the effect of large-area roller coating is different from that of internal corners and lamp grooves, and the texture is different. At present, many coating companies promise to paint for the owners free of charge, but they are basically not responsible for the basic treatment, and the basic treatment of latex paint is very important, because the basic problems directly reduce the final decoration effect of latex paint. In addition, the paint loss is relatively large, which is not affordable.

Second, is the wall painted or painted?

1, wall painting is to choose the brush construction technology, and get a plane effect, but if the brush technology is not very good, it will leave brush marks. Generally, wool brushes are used in home improvement, which are relatively soft and can minimize brush marks. It is worth noting that the proportion of water added during painting should be controlled between 20% and 30%, and should not exceed 35%, which is higher than this dilution share. After painting is completed, there are problems such as powder removal, sagging and floating color.

2. Painting the wall is done with a spray gun. The effect of this construction technology is that the wall is smooth and lubricated, with good hand feeling and fullness, which is very excellent. Spray painting is divided into air spraying and airless spraying. The final effect of the construction as required is the same, but the paint film sprayed by air will be relatively thin, only 20 microns at a time, so it will take many times to achieve better results. The paint film without air spraying is much thicker, 60 microns at a time, which can meet the requirements of construction thickness. The dilution share of air jet is similar to that of painting, and the dilution share of non-air jet varies from spray gun to spray gun, generally less than 20%.

The above is the introduction of painting and painting. They have their own advantages and disadvantages. You can choose according to your actual situation. I hope the above content will be helpful to everyone.
