The finish is the final coating of the coating. It is the last layer of the wall decoration in the building. The overall effect of the decoration is reflected through this layer. Therefore, there is a higher requirement for the materials used, not only To have a good color and brightness, but also requires a good resistance to pollution, aging, moisture, mold and good. So how does the wall paint brush ? Good wall paint construction not only brings a glazed appearance to the home, but also conceals the flaws of concealed construction. What I would like to introduce today is how to paint and paint the wall paint and how to use it. I believe that everyone will benefit from it.
How to paint the wall paint
Step one, preparation
The door, window frame, furniture and paint connection, paste color paper protection. Well-made wooden cabinets, partitions and other furniture should be sealed with newspapers so as not to be soiled by paint.
Step two, color
For walls that require color, the area should be accurately calculated in advance and the materials used should be evenly distributed. Then the primer is applied to prevent the wall surface from being wet and the color of the top coat is uniform. This prevents the appearance of water stains on the boards.
The order of topcoat construction: ceiling, lines, and back wall. Paint on the wall at least two times, the first time the paint can be added 5% to 10% of the water, to facilitate the absorption of the wall, the second time the paint can not add water, with the first pass of the coating there is a certain interval. Roller coating requires the use of two roller brushes at the same time. The coarse roller brush is followed by the roller brush. Use a thick roller to evenly paint the paint on the wall. Use a fine roller to brush over the rough roller. Brush it again to make the wall paint delicate and brush out the desired pattern.
Step three, brush construction
Use a brush to make up the paint on the edges of the wall and corner of the brush. After the roller brush is used for painting, it is necessary to use a brush to make up the paint on the edges of the wall and corners of the brush, especially the seams of the walls and corners, wooden cabinets, partitions, etc., and the corners of the walls.
Step four, polishing the wall
When the paint on the wall is dry, sand the wall with sandpaper to reduce the brush marks on the wall and make the wall more smooth. When polishing, be careful to feel the smoothness of the wall from time to time in order to judge where to polish. It should be noted that when sanding, try to use finer sandpaper. Usually the soft texture of the putty (such as 821) with 400 ~ 500 sandpaper, hard texture (such as wall lining, easy to flat) 360 ~ 400 The number is better. After thoroughly polishing, thoroughly clean the wall.
Step 5: Acceptance of wall paint
After the wall paint is finished, it takes 7 days to completely dry out, at which time it can exert its proper protection function. So pay attention to protection within 7 days. Remove the traces of paint from the lines of the foot and other places; check whether the color of the wall meets the design requirements and whether the color of the brushing surface is the same. In order to prevent the bottom, leaking brush, powder off the skin, blisters, bite color, falling and other quality defects.
Paint wall paint needs attention
1. When finishing a new wall, you don't need much preparation, but you should test alkalinity and moisture content. The moisture content of the wall can be tested with a water content tester; the pH can be tested with a pH test paper - the test paper is wetted with distilled water first, affixed to the substrate to be tested, and the wall is known to be alkaline based on the degree of discoloration.
2. If you find small white powder on the wall, it means that the wall contains salt and should be clean. After waiting for the cement walls to be dry and light-colored, the wall surface can be smoothed with sandpaper to paint. If there is too much white powder on the surface of the cement and it will precipitate out, please apply a layer of primer after cleaning to prevent salt from eroding the wall in the future.
3, on the treatment of painted walls: please use a sponge or rag to wipe, first clean the ceiling, and then clean the surrounding walls. If you wipe with water, remember to wait until the surface is completely dry before painting. If the original old paint surface is smooth, it must be slightly rubbed with sandpaper to enhance the adhesion of the new paint film.
Brush wall paint construction method and steps
1. The original wall putty needs to be wiped clean, exposing the bottom layer of cement, cracks to be affixed to kraft paper or anti-crack belts, and the exposed reinforcing heads are antirust paint.
2, scraping putty three times. The original switch sockets should be removed and removed, and the sockets at the bottom, the door and window openings, and the skirting along the skirting line should be scraped at the same time.
3, putty after drying with 200w light bulbs polished smooth, smooth, not allowed to have uneven, coarse sandpaper pattern, the roof and the wall of the template seam.
4. After the sandpaper is finished, the dust on the ground sill is cleaned and cleaned. Check the primer after brushing. In the ceiling of the glass, the rear part of the radiator and the corner part should be brushed in place. No leaking brush is allowed. After the primer is dry, it is polished and the brush is painted twice. Each time the painting is done, it must be done before it is dry. The brush should be uniform and uniform in color. Its dot size and degree of sparseness should not be connected to a sheet.
5. Clean up all the parts contaminated by paint or putty, including windows, glass, floor tiles, radiators, radiators, furniture, paint and putty on the baseboard, tear off the masking tape, and transport all the garbage to the downstairs. Trash cans.
6, lamps, socket switches, doors, floor after the completion of the repair, seams, to avoid re-contamination.
7, pay attention to the paint to be diluted according to the requirements of paint manufacturers, roller pattern or brush pattern to be as small as possible.
8, paint the paint with a color finish to notify the owners to see the color depth. When dark paint is applied, water must not be added. If the paint is not enough or there are other special conditions (including material quality problems), the person in charge of the site or the responsible person for purchase must be notified as soon as possible so as not to affect the progress of the whole project and the quality of the project.
9. All materials should be planned accurately in advance, avoid blindly or more than necessary, avoid material waste, all materials must not be destroyed before use, to prevent return or replacement, the remaining material should be protected and sealed, with color The paint is not allowed to run out, and each kind of paint must be used for repair when it is used. Seal it and save it to the owner.
