There is a decoration material like cotton, which is mainly aimed at old walls, and the renovation e

Housing decoration is an overall project, not only the wall needs to be treated, but also includes other contents: 1, wiring, water pipe embedded treatment: digging embedded wires and water pipes, sockets, network cables, etc. on the wall 2, wall treatment: first scrape the wall putty (big white), and re-scrape the putty.

Part of the wall needs to be leveled when scraping. The putty needs to be scraped twice before and after (scraping after drying) The wall is polished, and the wall is treated with sandpaper 3. Latex paint: the primer is twice (can be settled in one day) The latex paint is brushed twice (after drying, it is brushed again) 4. The latex paint needs to be dried before and after brushing, but it is too anxious.

Wall decoration materials include: latex paint, wallpaper, art bricks, real stone paint, art glass, decorative plates, mosaics, liquid wallpapers, white steel decorative boards, translucent stones, artificial stones, upholstery decorative fabrics, diatom mud, etc.

If it is not easy to renovate on the old wallpaper, if you use paint, you must first tear off the original wallpaper. It is recommended to peel off the wallpaper and paste the new wallpaper, which is very convenient, and you can wet the wall before getting it, so that it is good to get the old wallpaper off.

Wallpaper is a nasty thing that you can't fix.

Even if you buy the same wallpaper in two days, there will still be a color difference when you take it home, I suggest you don't fix it, either just replace it with a new one, or brush it with latex paint (I personally feel that this is economical and easier to deal with, there is no hidden danger).

If it is also made of wallpaper, paste it directly. To make latex paint, all the paint should be torn off.

1. Grassroots treatment:

First, remove the ash blocks, scum and other debris on the surface of the decoration with a knife, if there is oil on the surface, wash it with cleaning agent and water, and then use a palm brush to clean the surface dust after drying; After the surface is cleaned, brush one side with a dilution of water and interface agent (with a mix ratio of 10:1), and then fill the bottom unevenness with the bottom gypsum or caulking gypsum.

2. Scrape the putty twice:

The rubber scraper is full of scraping, and the horizontal scraping is required to be smooth, uniform, smooth, dense and flat, and the line corners and edges are neat. Try to scrape as thin as possible, do not leak scrape, do not leave the joint, and after the first putty is dry, polish it with coarse sandpaper. The method of scraping putty for the second pass is the same as for the first pass, but the direction of scraping is perpendicular to the previous putty.

3. Primer brushing and repairing:

The primer must be brushed evenly to ensure that every part of the wall is brushed, if the wall eats a large amount of paint, it is best to add a little more water to the primer to ensure that it can be painted evenly. Don't think that just because it's a primer, it's okay to use a roller that is a little worse, the effect of the primer will directly affect the effect of the topcoat, and you should use a roller with the same texture as the topcoat.

After the putty is polished, there will be some flaws (pit holes), it is generally difficult to see, only after brushing the paint will be obvious, then it is necessary to make up, pay attention to the repair must be polished and smooth, and then brush it with a slightly more water-added primer, so as not to paint the top paint because of the difference in draught with other walls and color difference.

4. Topcoat brushing

Do not add too much water, it will affect the thickness of the paint film, feel and the hardness of the paint film, try to choose a better tool, the hair of the drum is not too short, but it must be fine, so that the paint film will feel delicate, the main attention to the corner, the indirect stubble part of each roll and the direction of the paint.

5. Treatment of wall corners:

If you have the conditions, you can buy a side roller, the corners are painted with a plate and then use the edge roller to collect again, pay attention to the material of the edge roller to be consistent with the roller of the brush surface, and the paint in each stubble place must be evenly packed when brushing the large surface, not too thick nor too thin, otherwise it will be inconsistent due to the uneven thickness of the reflection.

When painting, there will be a painting action after each roll on the wall, which requires the direction of each roll to be consistent, otherwise it will cause the texture of each roll to be inconsistent, the reflection angle will be different, and there will be visual differences.

1. Use a vacuum cleaner to remove the dust, and use the brush of the vacuum cleaner to fully rub the surface to be cleaned to remove the dust.

2. For local pollution or oil stains, polyurethane diluent needs to be used for cleaning.

3. The parts with mold algae in the local area need to be cleaned with anti-mildew solution, dried or sprayed and then removed.

4. For the places that have been peeled off or damaged, first polish off the loose parts of the damaged parts, clean them up, and then use flexible putty to repair them. After the surface is repaired and leveled, the primer is applied.

5. Clean up the damaged and loose parts first, repair them with flexible putty, and coat them with 805 glue after the surface is repaired and smoothed.

6. Scrape putty paste on the base layer of glue.

7. Paint the primer, evenly brushed, and require no exposed bottom and falling phenomenon.

8. Paint the topcoat, evenly paint twice, and paint the second time after the first time is dry, requiring no exposed bottom and falling.

Today we will discuss that the wall is easy to stain after a long time of painting, so can it still be repainted?

Of course. Let's talk about it in detail.

First, clean the entire old wall before painting, use sandpaper to grind the wall again, there will be floating powder on the surface, and then you only need to sweep off the floating powder. First of all, the concave part of the wall should be filled with putty, and then the putty should be wiped as a whole after it is flat. Wait until the front brush is dry, brush the glue, wait for half a day, and you can paint the wall fabric for the first time.

After drying, apply putty powder again, and you can apply the strong fabric for the second time, during which time you can't let the dust get on it! Do your homework.

Second, protect the door and window frames: paste the color separation paper to protect the joints of doors, window frames, furniture and paint. Wooden cabinets, partitions and other furniture should be sealed with newspaper to prevent paint dripping and staining the furniture.

Be careful with paint tinting: the area of the wall with color requirements should be accurately calculated in advance, and the materials used should be evenly mixed at one time. The wall primer is well applied:

The wall should be primed before painting to prevent the wall from being damp, so that the color of the topcoat is uniform, and to prevent the water stains caused by wood acid.

Third, don't underestimate the details of construction.

Drum painting: topcoat construction sequence: first ceiling, lines, and then wall. Paint on the wall at least twice, the first coating can add 5-10% water, convenient for the wall to absorb, the second topcoat can not add water, and the first coating has a certain interval time.

Tips for construction tools: When rolling coating, you need to use two kinds of roller brushes at the same time, the coarse roller brush goes first, and the fine roller brush follows immediately. Use a coarse roller to evenly coat the paint on the wall, and then use a fine roller to brush the place where the coarse roller has been brushed, and re-brush it to make the wall paint delicate and brush out the desired pattern.

Pay attention to the roller coating, do not adhere too much paint to the roller, the rolling pressure should be uniform, and the speed should be moderate. Roll evenly in all directions, horizontal, vertical, and diagonal.

Fourth, post-construction repair details.

Brush repair: Generally, after painting with a roller brush, it is necessary to use a brush to repair the missing places on the wall edges and corners, especially the joints between the wall and the corners, wooden cabinets, partitions, etc., and the corners of the wall.

Wall sanding: After the wall paint is dry, sandpaper is used to polish the wall to reduce the wall brush marks and make the wall smoother. When sanding, pay attention to feel the smoothness of the wall with your hands from time to time, so as to judge the need for polishing, and the grinding strength should be moderate and the range should be wide.

The construction plan of wall painting is not the same, and it is necessary to formulate a suitable construction plan according to the actual wall condition and effect requirements.

Dulux Easy Paint Renewal Service shares professional wall painting steps:

Wall assessment: It is not uncommon for a wall to have problems within a period of time after construction has been completed. In addition to the lack of professionalism of the construction team, a large part of the reason is that the wall assessment is not done well.

In order to maintain a good wall effect for a long time, it is necessary to fully understand the condition of the wall and evaluate the wall before construction. The content of the wall assessment includes the area, humidity and the condition of the bottom layer of the wall. In addition, external factors should also be taken into account, such as whether there is a water leak in the surrounding neighbor's house, whether there is a subway line in the vicinity, etc.

According to the condition or demand of the wall after evaluation, the construction plan is formulated, the appropriate coating products are selected, the amount of paint is calculated, and the wall color is selected.

Relocation protection: After the plan is formulated, you can't start painting directly, and it is more troublesome to move and protect the items in your home before construction than painting the wall. First of all, it is necessary to clean up the small objects in the home, such as decorations, clothes, etc., and move the furniture and appliances against the wall to facilitate the construction.

At the same time, because it is inevitable that the paint will splash off during the painting process, it is necessary to use professional protective materials to cover the floor, furniture, etc.

1) Old houses with relatively intact walls (local walls have stains, bumps, and cracks): The problems of local walls should be repaired first, and after the walls are smoothed, the primer should be painted once and the topcoat twice;

2) Old houses with serious wall problems (wall peeling, peeling, mildew, etc.): all the problem walls need to be eradicated, the base layer is painted and repaired, and then the putty is scraped twice and then polished and smoothed, and finally the primer is painted once and the topcoat is applied twice;

3) Newly renovated house (when the wall is in good condition): after directly polishing the wall, apply the primer once and the topcoat twice;

4) Blank room: scrape the putty twice, polish and smooth the wall, apply the primer once and the topcoat twice.

Cleaning and homing: After painting, the final cleaning and homing work is required. Wait until the last topcoat is dry, remove the protective material, clean up the construction waste, and reset the item.

The renovation of the home is complete. The construction time will be affected by factors such as the type of construction and the weather. Generally, it takes about 2-3 days for the new house to be painted or the wall is in good condition, and it takes 7-10 days to complete the old house with more serious problems.

The wall painting project not only requires the labor of the painting process, but also the painstaking organization and removal of furniture, cleaning and returning to its place, etc.

Secondary painting is possible. Generally, the wall will become dirty for a long time, as long as it is painted twice.

It can be repainted, but the surface must be thoroughly cleaned before it can be repainted.

Yes, it can be carried out. You can paint directly on the original wall, and you can paint the wall several times if you want to, and there are no technical requirements.

If the original wall is not smoky and alkali peeling due to the short living time, you can directly use 300 sandpaper and above sandpaper to polish it once, clean up the floating dust and directly paint the primer twice and the topcoat can be, my wall appears alkali peeling and yellowing, it is necessary to eradicate the wall putty layer and paint with high-quality interface agent, scrape the putty and then brush the primer and topcoat.

Brush away the polluted unevenness first, then check the ash layer and paste the wallpaper. The area is 150 square meters. How much time does it take? How much does it cost? After brushing, is the cleaning work with a sucker? Who's going to do it? Please advise.

Hello. There are many situations for latex paint wall renovation, and the construction plan corresponding to different base conditions is also different. According to what you said, if there is no problem with the base layer of the wall, but the color is a little old, then it can be quickly refreshed to cover the original color.

This construction method is divided into two situations: 1. The original wall is darker, and the putty needs to be scraped as a whole to cover the original color. 2. The color of the original wall is lighter, and the primer and topcoat can be painted directly.

Hope it helps.

Look at the type of paint before, whether it is latex paint, and then look at the color of the previous paint, white *** latex paint, directly sanded with spray paint, bad can only be scraped and re-painted putty paste polishing, and then painted.

It is recommended that if you want to save money, you can put sandpaper on it, mend the cracks, use putty, if the cracks are large, use the caulking tape, and then fill the level, and then brush the latex paint.

The original wall skin is shoveled to the original cement layer, and then the wall is rolled once, the wall treasure is scraped three times, the putty is sealed, and the primer is OK for the last two times.

If the original wall is simply old and has no peeling, you can clean it directly, roll (spray) it with a roller brush or spraying machine, wait until it is dry, and then it will be OK on it two times!

If there are cracks or bursting skin, you need to clean up the floating dust and then use the shovel to remove the wall, there are pits and uneven places with gypsum leveling, there are cracks with cloth bags or net brushes to paste the cracks with milky white glue, the cracks need to scrape twice putty The first time is to stick the cloth bag and the net, the second time leveling, and finally the wall must be smooth, and then brush the Yunquan water-based paint! It's OK to brush it twice!

A relatively simple way: first look at the wall balcony, whether there is cracking and peeling on the outer wall of the bathroom, shovel it off, use putty to make up the level, put a bandage on the cracks, and make up again after the bandage is dry. Then sandpaper as a whole, about 240, slightly larger can also be.

Especially where the color becomes heavier, use a coarser sanding. After all the grinding is smoothed, dust off the floating ash and apply latex paint, OK
