Material selection of paint | selection of painting tools according to construction process

Core tip: in the home wall decoration, three construction processes are often used for coating: brushing, rolling and spraying For these three methods, the tools selected are different, and the specific operation is also different Here is an introduction to the differences between the three different painting tools 1、 Brush brush the tool of this process is a brush, usually a soft wool brush or synthetic fiber brush Because the brush will leave some brush marks in the process of operation, the soft material can reduce the brush marks When choosing a brush, we should pay attention to the different specifications of the brush and the quality of the tail brush If we choose a high-quality brush, the effect will be better Well Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: in the home wall decoration, for paint, often use brush, roll, spray three kinds of construction technology, for these three ways, the choice of tools is not the same, in the specific operation is also different, the following three different paint tools are introduced for you what is the difference 1、 Brush brush the tool of this process is a brush, usually a soft wool brush or synthetic fiber brush Because the brush will leave some brush marks in the process of operation, the soft material can reduce the brush marks When choosing a brush, we should pay attention to the different specifications of the brush and the quality of the tail brush If we choose a high-quality brush, the effect will be better A good brush has good tail bifurcations, flexibility, and is not easy to depilate There are layers of bristles When brushing paint with brush, pay attention to the proportion of water and paint to be well controlled The water should not exceed 35%, preferably between 20% and 30% If there is too much water, it is easy to have many situations such as powder removal, floating color, sagging and so on, which affects the final aesthetic effect of the wall 2、 Roller roller is a tool for rolling this way Its effect is rough surface effect, similar to wallpaper The drum is specifically divided into long wool drum, medium wool drum and short wool drum The medium wool drum is made of synthetic fiber, with a length of about 10 mm Because there are many paint absorbers, the coating is thick after rolling, and the overall effect is rough, so it is seldom used in home decoration The hair length of short hair roller is between 4-7mm, which is mostly used in home decoration The wall surface is relatively smooth, the construction is relatively simple, and the effect pattern is relatively shallow, which is suitable for daily cleaning Because the effect of long hair roller is easy to hang ash, it is suitable for local use in home decoration, such as TV background wall, sofa background wall, etc Before the formal construction, the effect can be seen in the inconspicuous place first Pay attention to that when the roller is used to brush the wall, the paint can add less water or no water 3、 Spray gun is used in spraying construction, which is usually used in projects with large area demand and high wall quality requirements Spraying is divided into air spraying and airless spraying The construction effect is the same The difference is that the film sprayed with air is thinner than that sprayed without air It is 20 microns at a time, and it is usually sprayed several times to achieve better effect The film of airless spraying will be relatively thick, which can reach 60 microns at a time, and can meet the needs of one spraying In the dilution of the coating, the proportion of water added for airless spraying is similar to that of the brush, and the dilution for airless spraying varies according to the specific machine performance, generally less than 20% Brush and roll are commonly used in home wall decoration These two painting tools are not the same, and the wall effect is not the same When decorating, you need to choose the one suitable for home style to make the space harmonious Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
