My house needs to be renovated, the wall next door is a rough house, and the cement wall is not pain

If it is a newly bought rough house, it is likely to be a rough cement wall that has not undergone any treatment. In order to decorate the wall conveniently, you may ask how to decorate the cement wall. If we force the wallpaper on the cement wall, it won't be long before it will fall off on its own.

If you want to paste wallpaper, the wall must be flat, but the cement wall can not be smooth no matter how careful you are when you paint, and you can see that the cement wall is curved when you look at it from the side of the wall. So, let's introduce how to decorate the cement wall.

In fact, the treatment of the cement wall is not very difficult, if you want to paste the wallpaper, we can treat the cement wall after leveling, and then paste the wallpaper program, but the cement wall itself is also a way of industrial style, if you do not want to carry out large-scale construction, you can use the original ecological pattern of the cement wall to decorate the overall space.

1. How to decorate the cement wall The requirements of the wallpaper wall are flat. The cement wall is not smooth in this province, it needs to be sanded with sandpaper, there can be no dust, small particles, cracks, cavities, etc., otherwise it will have an impact, the best thing is to brush the wall with a layer of base film, which can make the wall smooth. First of all, do the grassroots treatment:

Use putty to make the base layer of the wall flattened. Next, choose a latex paint primer with trustworthy quality. Dulux's latex paint is good, as long as it is, the quality is ***.

Primer is generally enough to do it once. Finally, the base film of the wall cloth is painted. Once you've done that, you'll be able to paste your favorite wallpaper on the wall.

The advantage of brushing the base film is also that it is convenient to change the wallpaper in the future, and the wall is intact after the old wallpaper is torn off. It can penetrate into the base surface, making the base surface stronger and more durable, and at the same time not affected by the base surface, moisture, moisture and alkaline substances, and will not cause the base flour to be powdered.

Cement walls cannot be painted directly. Even if the wall is smooth to the touch, if the wall is not treated, it will crack and peel and hollow if the paint is applied directly. Moreover, if the paint is applied directly, it may not cover the background color of the cement wall.

Therefore, it is necessary to paint the interface agent on the cement wall first, and then carry out leveling treatment to determine that the flatness of the wall is less than 4mm. Finally, scrape the water-resistant putty twice in the batch. After scraping the water-resistant putty, it is good to paint the paint.

Putty can mask the gray color of the cement.

As long as it is not an exterior wall, there is no impact, if it is an exterior wall, it will be invaded by rainwater, and water seepage will affect the interior decoration.

Step 1: Check the wall.

The walls in the rough house are generally cement walls, so before decorating the walls, it is necessary to conduct a detailed inspection of the walls. Comprehensively check whether the cement front that needs to be painted in the blank room is solid and smooth. If the plastering layer spit on the wall is not strong enough or there are large gaps and cavities, it is recommended to complain to the developer or property and ask it to be redone.

However, if the flatness of the wall is poor (the error is greater than plus or minus 5mm), you should consider making plaster to level it first. When inspecting the wall, you also need to use a horizontal line to test whether the wall is level, if it does not maintain a certain levelness, you can ask the developer to redo it.

Step 2: Finished product protection.

Before decorating the wall, there should be other projects after the completion of the wall, it is inevitable that there will be dust when the wall is treated, and there will be putty, paint or other glue dripping when brushing the putty, so before the wall is decorated, it is necessary to protect the other finished products in the room. Generally, you can buy plastic paper of the right size in a convenience store and wrap the finished product that needs to be protected on the construction site, but you should be careful about the shielding strength of the finished product to avoid the possibility of damage to the finished product.

Step 3: Preparation before scraping putty.

Before scraping putty, it is necessary to ensure that the wall is solid and flat, and the uneven place can be cleaned with a steel brush or other tools, and the sunken place can be filled with cement, so that the wall is free of floating soil and floating and sinking. Roll the concrete interface agent on the wall, roll it evenly as much as possible, and then you can carry out the putty painting work on the wall after it is dry.

Step 4: Scrape putty.

Before scraping putty on the wall in the blank room, the flatness of the wall should be measured, and a detection ruler of more than two meters can be used to measure, so that the method of scraping putty can be determined. Generally, the putty on the wall needs to be scraped twice, which can not only level the wall, but also make the background color of the wall uniform. If the flatness of the wall is poor, you can brush it a few more times.

If the flatness of the wall is very poor or the slope of the wall is very large, you can consider scraping the leveling plaster first, and then scraping the putty, and the interval between each batch of putty scraping should be more than 2 hours (after the surface is dry).

Step 5: Paint.

There are two kinds of paint, primer and topcoat, first brush the primer, clean up the dust on the wall after sanding and smoothing, and then you can apply the primer. The primer can be applied once, making sure it is even, and when it dries, you can proceed to the next step. The topcoat is generally brushed twice, and the interval between each time is more than 2-4 hours (subject to the topcoat is dry).

After the second brush of the topcoat, you need to wait 1-2 days to completely dry, before the paint is completely dry, you must pay attention to waterproof, drought-proof, sunscreen to prevent problems with the paint film.

Then scrape putty, the original wall on the glue is insufficient, if you do not shovel off the paint wall will be a large area of skin, our wall treatment is to brush the wall solid, in addition to alkali, in fact, that layer is useless, maybe you don't have to scrape the wall when renting a house, you must shovel off when you live, that is, look better when you look at it, it feels like a look more high-end than the cement wall, you can naturally add some money, and the putty will be mixed with white glue.

If your house is not rented, when you want to renovate it yourself, you must shovel it. If you brush putty and latex paint directly on top of it, the adhesion is not enough. I have been to some residential measurement houses, and the wall was a cement wall when it was delivered, and it was easier to decorate it later.

That is to say, when you look good-looking, you feel that you can add some money than the cement wall, in fact, that layer is useless, maybe you don't have to scrape the wall when you rent the house, you must shovel it off when you live, the original glue on the wall is insufficient, if you don't shovel off the paint wall, it will be a large area of skin, our wall treatment is to brush the wall solid, remove alkali, and then scrape putty, the putty will be mixed with white glue, and then polish and smooth the paint.

The first process of new house decoration on the wall is to shovel the wall skin, which is what it says, the developer has brushed a thin layer of white ash on the cement wall, which is of poor quality and poor adhesion.

Generally, it is mostly engineering putty powder, and it is recommended to wrap it up and redo it.

Yes, it is not renovated, so it is actually convenient to decorate.

Scraping construction is actually what people often say "scraping white", in general, it is a kind of white plaster finish, also known as "big white", "big white pulp", which is cement sand at the base level.

The foundation of the slurry concrete wall is scraped with a prepared lime plaster finish, compacted and washed before it dries, so that the surface is dry and smooth. This kind of large white pulp finish does not contain fiber materials, and there are ordinary large white pulp, waterproof large white pulp,

A variety of formulas of color white pulp.

It may still be a brick wall, and you will understand it when you install the air conditioner.

98% of them are cement walls, but they are generally very flat.

Wallpaper cannot be directly attached to the cement wall.

No matter how fine the cement wall is, it can't stick to the wallpaper, and even if it is barely pasted, it will fall off. The seams of the wallpaper will be very obvious, the visual effect will be very bad, and there will often be cracks and falling off.

So how to decorate the cement wall to put wallpaper on it. The requirements for the wallpaper wall are flat. The cement wall itself is not smooth, it needs to be sanded with sandpaper, there can be no dust, small particles, cracks, cavities, etc., otherwise it will be affected, the best thing is to brush the wall with a layer of base film, which can make the wall smooth.

First of all, it is necessary to do a good job in the base treatment: use putty to make the base layer of the wall flat. Then you have to choose a *** latex paint primer, (this one is your own choice, *** can be,) the primer is enough to do it once in one shift.

Finally, the wallpaper base film is painted. Once you've done that, you can put your favorite wallpaper on the wall.

Note: The cement wall can not be directly painted, even if the wall feels very smooth, if the wall is not treated and directly painted, there will be cracks, peeling, and hollowing in the future. Moreover, direct brushing of paint may not cover the background color of the cement wall, so it is necessary to apply the interface agent on the cement wall first, and then carry out leveling treatment to confirm that the flatness of the wall is less than 4mm.

Finally, after scraping the water-resistant putty twice, you can brush the paint.

It is best to paste wallpaper after painting, so that it is good to paste and not easy to get up.

The cement is not well pasted. Foams easily.

1. If the wall is very flat, it can not be painted, if it is not flat or dusty, it needs to be painted, otherwise the service life of the wallpaper is relatively short, and there will be wall hollowing.

2, but before the paste must be polished and flattened and then re-brush a lime slurry to ensure the flatness of the wall, and then paste the wallpaper after drying, the uneven surface of the wallpaper will have hollowing, bubbles and other phenomena, affecting the service life.

3. Basically the same as the general paint finish, it must be plastered two to three times putty, polished and smoothed after drying, and then painted with the wallpaper base film and then pasted with wallpaper, you can also use latex paint dilution and brush it once to replace the base film, the purpose is to prevent the surface dust from being too soft and affecting the wallpaper stickiness, so the base layer should have a certain strength, and the water absorption should not be too large, otherwise it will cause too fast drying, or even fall off and rework.
