Core tip: wall painting is a very important part of home decoration and the last step of wall construction Good wall paint construction can not only bring a bright appearance to the home, but also cover up the defects of concealed project construction Next, Xiangxiang Xiaobian will introduce the construction process of wall paint for you Base course treatment: the peeling and loose parts of the wall shall be removed, and the cement mortar shall be used for patching The cracks are usually covered with kraft paper tape and white emulsion Generally, non load-bearing walls such as light body walls and thermal insulation walls need to be pasted with cloth Try to choose wall cloth with better texture and white emulsion or mesh cloth Compared with the anti crack effect of mesh cloth, it will be better to brush the interface agent: the interface agent can increase 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: wall painting is a very important part of home decoration, but also the last step of wall construction Good wall paint construction can not only bring a bright appearance to the home, but also cover up the defects of concealed project construction Next, Xiangxiang Xiaobian will introduce the construction process of wall paint for you Base course treatment: the peeling and loose parts of the wall shall be removed, and the cement mortar shall be used for patching The cracks are usually covered with kraft paper tape and white emulsion Generally, non load-bearing walls such as light body walls and thermal insulation walls need to be pasted Try to choose wall cloth with better texture and white emulsion or grid cloth Compared with the anti crack effect of grid cloth, it will be a little better to brush the interface agent: the interface agent can enhance the adhesion to the base layer, avoid the phenomenon of hollowing and peeling of the plastering layer, so as to replace the artificial roughening treatment, saving time and effort When painting the interface agent, it is necessary to evenly brush the wall surface for leveling: the uneven wall surface needs to be leveled, and the uneven wall surface needs to be leveled with plaster, so that the error of the wall surface does not exceed 3mm If the internal and external corners are not straight, plastering gypsum is also required, and putty is applied with guiding rule: it is better to select putty with high particle fineness and hard texture, and putty shall be applied three times The first time is generally thicker because it involves leveling The second and third times should be thinner, mainly for light absorption, so that the wall looks more smooth and flat After three times of application, the thickness of putty shall not be more than 3mm, otherwise it is easy to crack and polish: polishing is a key step in the painter's steps Only after polishing, can the effect of painting be good Try to use finer sandpaper If the sandpaper is too thick, it will leave deep sand marks After polishing, the wall must be cleaned thoroughly to avoid too much dust, affecting the adhesion of the paint The concave convex difference shall not be more than 3mm, and the primer shall be brushed evenly to ensure that every part of the wall is brushed If the wall has a large amount of paint, it is better to add a little more water to the primer to ensure that it can be brushed evenly Mending: after the putty is polished, there will be some defects Generally, it is difficult to see clearly It will be obvious only after one coat of paint is applied At this time, mending is needed Pay attention to polish and level the repair, and then brush the primer with a little more water to avoid color difference due to different water consumption of other walls when painting the top coat: do not add too much water, which will affect the thickness, feel and hardness of the paint film Try to choose a better tool The painting mainly focuses on the corner of the wall, the middle part of each roll and the direction of paint collection There are eight steps in the process of wall paint construction, namely, base treatment, interface agent, wall leveling, putty application, wall polishing, primer application, wall repair and finish painting Each step has its own operation method and construction requirements When painting the wall, each step should be done well according to the specific requirements Hope to help you!
