What kind of paint is good for old wall renovation?

Grassroots treatment. Remove the peeling and loose parts of the wall and remear it with cement mortar. Where there are cracks, kraft paper tape and white latex are generally used to stick the cracks, and non-load-bearing walls such as light walls and thermal insulation walls need to be pasted.

Brush the interface agent. The interface agent can enhance the adhesion to the base layer, avoid the phenomenon of hollowing and shelling of the plastering layer, so as to replace the manual chiseling treatment, saving time and effort. When brushing the interface agent, it must be brushed until it is evenly brushed, and the uneven wall needs to be leveled.

Batch scraping putty. It is better to choose putty with higher particle fineness and harder texture, and the putty should be batched three times. Try to use fine sandpaper for sanding, and be sure to clean the wall thoroughly after sanding.

Brush the primer. The primer must be brushed evenly, polished and smooth, and then brushed with a primer with a little more water, so as not to have color difference when brushing the topcoat because of the difference in draught with other walls.

Brush the topcoat. Do not add too much water to the topcoat, which will affect the thickness of the paint film, the feel and the hardness of the paint film. Try to choose a better tool. The main attention to the corners of the wall, the indirect part of the stubble in each roll and the direction of the paint is collected. The topcoat is generally brushed twice.

The old wall is renovated, and the paint cannot be directly painted, so the wall skin needs to be shoveled first. The old wall skin must be removed. Because the old wall skin is easy to chalize, it will be layered with the later scraping putty when used, causing the wall skin to fall off and affecting the quality of use.

When decorating, you should also pay attention to whether the walls are sand-gray walls or lightweight walls, because they are prone to cracks, and it is best to do a patch treatment. If the wall is not in good condition, gypsum board can be laid, but this method is more expensive.

To renovate the old wall, you can first remove the old wall and do sanding and leveling. Then re-apply the putty and primer, and the topcoat can be imported from Canada.

In the case of construction, it is all one bottom and two sides. Environmentally friendly and non-toxic.

1. The effect is white and smooth, and the feel is good.

The decoration made of Lines water-resistant putty is very good, the wall is white and it is a kind of slippery, we feel better when we touch it, and this water-resistant putty will not be the same as other paint putty after the stucco construction, the surface of the water-resistant putty is relatively smooth and delicate, and the putty will give us a slippery feel after the light collection treatment, so this water-resistant putty is the preferred decoration material for friends.

2. Good durability, no need to eradicate for multiple decorations.

Water-resistant putty is used for a long time, has a very high shelf life, and can withstand stirring and repeated application. Ordinary putty powder is to be cleaned up together with the original paint, and then the putty can be scraped again, water-resistant putty it can be done once and for all, after many years of use for two or three times when the old house is renovated, there is no need to shovel down the putty layer, the next step can be carried out after polishing the surface layer and local repair, it can be said that the use of this saves time and effort and protects the wall.

3. Save the amount of paint and the comprehensive cost is low.

Water-resistant putty powder also has a feature that the whiteness and density are better, so that the adhesion and hiding power of the coating per unit area are better, and it can be said that this material will save 30 40% compared with ordinary putty powder. If you really want to calculate from the amount of paint and the time of secondary decoration, in fact, the cost of using water-resistant putty powder is low.

Part 1: Roll glue on the wall.

There is a link that cannot be omitted between the repair of the base layer and the scraping of putty to batch the wall - the wall is covered with glue. After repairing the base layer of the wall, the wall needs to be rolled with ordinary 801 construction glue first, and then scrape the putty after the glue is dry, so as to ensure the close adhesion between the new layer and the base layer, and avoid the problem of cracking and falling off the wall after painting.

Part 2: Cracks need to be treated differently.

The cracks on the wall are divided into several types according to their causes, and the slight cracks can be directly mixed with putty powder with glue, or the wall paint can be repainted, and the treatment methods for more serious cracks are different.

Due to the settlement of the wall, improper treatment of the base layer and other reasons, the wall will have a very serious crack, these cracks need to be shoveled off the coating when reprocessing, with a special crack sealing corner paper tape to fill the cracks, and then roll glue, scrape putty, brush primer and topcoat, and finally clean the wall once.

Part 3: Moisture-proof treatment of hidden corners.

Hidden walls behind wall corners and furniture and appliances are left without light for a long time, and once they are damp, they can easily become moldy and discolored. For moldy and discolored walls, the coating needs to be shoveled off, and after a separate waterproof layer and other moisture-proof treatment, you can continue to renovate according to the general steps of wall construction. It should be noted that the primer, topcoat and other paints used in the construction should be waterproof to avoid the recurrence of dampness on the wall.

There have always been many kinds of materials for wall decoration, but more and more advanced materials are constantly emerging, so many are slowly being eliminated. Decoration materials are: wallpaper, latex paint, and diatom mud, and diatom mud is an environmentally friendly material that has only emerged in recent years, and he has many colors, fancy for consumers to choose, so it is recommended that you still use diatom mud!

The precautions for the renovation of the old wall are: 1. When the problem of the wall is not too serious, we can choose the local renovation of the old wall, first polish the local surface that needs to be renovated to keep the whole smooth, fill it with putty, and finally repaint the cracked and peeling wall. When painting, you need to pay attention to the color of the wall paint, so as to avoid obvious color difference on the wall after painting.

2. When the wall is moldy, the renovation wall is mildew, and the small-scale mildew can be simply treated with a rag dipped in bleach, and then dried after removing the mold, but when the wall is moldy on a large scale, it is necessary to remove the moldy part, and then repaint it after smoothing the surface with sandpaper. 3. After the overall renovation of the wall after long-term residence, the overall fading and large-scale cracking, peeling and other problems of the wall need to be carried out in a timely manner, and the "four steps" of renovation need to be strictly adhered to in the construction process of the old wall renovation, that is, the surface is removed first, and then the base treatment, moisture-proof treatment, and finally re-painted. 4. Precautions for old wall renovation If the renovation of the old wall occurs five years after the initial decoration, then the putty must be removed and repainted.

Because the putty material has begun to deteriorate after five years of use, in addition, the repair of the old wall renovation needs to be as comprehensive as possible, and the larger the repair, the more the color difference in the interior can be avoided.

The old wall is renovated, and it is still the porcelain powder used in the past, that only shovel off, re-foundation, then the material you have to buy particle powder first, white latex, if the front is not uneven, you also need high ash.

In the back of the look, you brush yourself?? It's best not to operate it yourself, the flatness of the wall is like a person's face, and no one wants to make their face uneven, right? Suggestion, please have a good master, buy your own materials, people work on the line, yes just said priming, there is latex paint, then I tell you a few, these I recommend that my customers have used, the mid-range are:

Dulux Caramide, Nippon Paint Medri,,, high-end are: Master, Dufang,,, if the economy allows, you can spray. By the way, there is also a grader (material) if you want to be simpler, just remove it, brush all the latex paint, and if you want to retain such a decorative effect, you can wrap the panel with the same color as your previous panel, and brush the varnish.

1. The choice of paint for the renovation of the old wall first depends on the packaging of latex paint. However, it should be noted that the packaging of good-looking coatings is not necessarily intrinsic, and the quality is also very good. In order to attract customers, some manufacturers deliberately exaggerate the performance and efficacy of products on the packaging of products.

Therefore, it is recommended that consumers pay attention to other aspects in addition to looking at the product packaging, such as checking the detailed inspection list of the product.

2. When purchasing, you can identify the quality of the paint film by viewing or touching the sample of the paint. Good latex paint is usually dense, delicate and shiny; Poor latex paints are usually rougher.

3. Smell the smell before construction, if there is a smell, then you should pay attention, it is very likely that there is a problem with the coating. In particular, it should be noted that the sedan car is often used to cover up the pungent smell of the paint with this fragrance.

1. Choose a reliable brand.

Don't blindly believe in concepts such as "clean taste" and "environmental protection", and pay attention to the brand of the product.

2. Good paint will flow into a fan shape.

After mixing the paint evenly with a wooden stick, pick it up, and when the high-quality product flows downward, it will form a fan shape.

3. Ask for a test report.

See if antimony, arsenic, barium, cadmium, chromium, lead, mercury, and selenium are qualified.

4. The smell of paint should be fresh.

In the same space, too much furniture will also produce a superposition effect of formaldehyde.

5. Choose environmentally friendly water-based paint.

If it can be replaced, try to use water-based paint as a decorative material to reduce the toxicity of heavy metals.

6. Carry out construction according to the requirements.

Coating construction is also a very important link, and the construction should be carried out in strict accordance with the requirements of the product construction manual.

7. It is safer to use light paint.

Especially for the walls of children's rooms, try to use less paint, if you must use it, it is best to choose a lighter color paint.

8. The construction environment should be ventilated.

The construction environment should be ventilated, and if the product has special requirements for the construction environment, it must be carried out according to the requirements.

As long as it's not too low, it's basically okay.
