Blank wall - brush 1 time interface agent - crack treatment - leveling (including the yin and yang angle to find straight) - patch - scrape 2-3 times putty - grinding - primer - find repair grinding (finding place Be sure to use a primer again on the 1st) - two coats of paint - maintenance Interface agent: brush interface agent must be brushed, but also brush uniform. Cracks: In general, cracks are applied with kraft paper tape and white latex (but no guarantee that 100% will not crack again). Leveling: uneven walls need to be leveled, the general plaster is more commonly used, concave and convex difference does not exceed 0.5 centimeters. Patch: Non-load-bearing walls such as light walls and heat-insulating walls all need to be patched. Try to choose a wall cloth and white latex with a better texture. If possible, use a grid cloth to achieve better anti-crack effect. a little. Putty: It is better to use putty with high grain fineness and hard texture. It is also possible to add certain white latex in putty to improve the hardness of putty. Grinding: Use finer sandpaper as much as possible, generally softer putty (such as 821) with sandpaper of 400-500, hard texture (such as wall lining, easy to flat) with 360-400, if sandpaper If it is too thick, it will leave a deep sand mark and the paint cannot be covered. After polishing, you must thoroughly clean the wall to avoid too much dust, affecting the paint adhesion. The unevenness does not exceed 3 mm. Primer: The primer must be evenly brushed to ensure that the walls are brushed in every place. If the wall has a large amount of paint to eat, the primer is best to add a little amount of water to ensure even brushing. Do not think it is because it is the primer to use a little more than a roller on it, the primer brushing effect will directly affect the effect of the top coat, use the same texture as the paint roller. Looking for supplements: After putty polishing, some blemishes (holes) will be left. Under normal circumstances, it is difficult to see. Only after brushing the paint will it be obvious. At this time, you will need to find a supplement. Pay attention to make sure to make up and polish. Use a primer with a little more water to brush it again, so as not to have a color difference due to the different amount of draught when compared to other walls. Topcoat: Do not add excessive water. It will affect the film thickness, feel, and film hardness. Try to choose a better tool. The roller's hair should not be too short, but it must be fine, so that the paint film will feel Delicate, brushing mainly pay attention to the corners, each part of the roll and the direction of paint collection, corner treatment, most of the time is brushing with a row of pen or board brush, this will easily cause the edge of the texture and the entire surface is inconsistent, visually there will be Differences, if you have conditions, you can buy an edge roller, and then use the edge roller to paint it again. Take care that the material of the edge roller is the same as the roller of the big roller. When brushing the big face, The paint must be mixed evenly in the place where it is rolled up. It must not be too thick or too thin. Otherwise, it will cause inconsistent reflection because of the uneven thickness. When it is painted, it will have a paint-removing action after it is rolled on the wall. This will require every roll. The direction of lacquer must be the same, otherwise it will cause the texture of each roller to go out of shape, the angle of reflection will be different, and there will be differences in vision. (Recommendation: buy a tray before painting, the shop will have to sell, use the tray to ensure that each brushing a roll, the paint on the roller is the same, so that the brush is very uniform.) Maintenance: 4 hours after the latex paint is applied, it will be dry, but the dried paint film has not reached a certain hardness. This requires care. It is very simple. Do not scrub or touch the wall within 7-10 days. Act can be. Three trees painted latex paint Heilongjiang Junhe Building Materials Technology Co., Ltd , https://www.junhejiancai.com
