After the house is renovated, the wall is not finished, can I paint it directly?

Latex paint. I believe everyone is very familiar with it, and it will be used in home decoration. However, for different materials and different people, the effect of painting is still different, so in order to ensure the quality of brushing latex paint, construction operation is also the main part.

We will introduce you to the correct steps of painting latex paint directly on the wall and the correct steps for painting latex paint.

1. Can latex paint paint directly brush the wall As long as the original wall is painted with latex paint, and the wall is smooth, you can directly brush latex paint. The color of the newly brushed latex paint can be set according to your needs, just prepare the roller and brush, and pay attention to uniformity when applying. In addition, the amount of each color should be prepared sufficiently, otherwise there will be color difference when it is not enough.

Second, the correct steps of brushing latex paint The basic treatment of the wall When painting the wall, the wall should be cleaned first, and the wall stains can be directly sanded with sandpaper, and then the latex paint should be brushed; If the wall is very dirty, the original putty should be removed.

Remove it all, then reapply putty, then latex paint.

Clean up old walls.

For the dedusting of the old wall, it should be completely removed, and then white cement should be used.

Rub a layer on top as a basal layer; In addition, for the smooth wall, we only need to sand.

Brush the primer. When brushing latex paint, a layer of primer should be applied first, and the primer is used as the base surface. If there is no primer, after a long time, the wall will be depowdered, long and even discolored.

Wall repairs. For the painted wall, if you want to make a second repair is very troublesome, if you make up a single piece, the whole wall will have obvious color difference, and the aesthetics will be reduced; Therefore, it is best to repair the entire wall.

Anti-chromatic aberration. In order to prevent color difference, when brushing latex paint, you can choose latex paint of the same brand specifications, make adequate preparations, and it is best to paint the whole wall at one time.

OK. I don't know if the original wall has been painted, if not, it is okay, but it is best to include all a putty, because the plastering layer of the wall is plastered with mortar, there is a possibility of sanding, so include a thin putty, polish it, you can paint.

No, you should understand the reason why the wall is not finished, and then use a professional method to repair it, and direct painting may affect the aesthetics of the wall.

It is not possible to paint directly on it, if you paint it directly, the wall will be smoother, and it will also be very troublesome to paint off.

The walls of the hardcover room can be painted directly.

The premise is that you must use the same brand of latex paint as before (the best model is also the same), you must brush it twice when brushing, and it must be completely dry after the first paint before you can brush it a second time, which is the most important thing. If there is peeling, then remove the putty from the peeling area.

When painting the wall of the hardcover room, you can remove all the original decorations on the wall, polish the wall with sandpaper, and repair the subtle cracks on the wall by grinding work.

Selection of tools for painting

When painting, it is the most economical to use a row of brushes, but it is more time-consuming, of course, slow work is still good, and the wall effect is flat in the end. Due to the rapid drying of glue coating, each brush surface should be completed as much as possible, otherwise it is easy to produce joints. When brushing manually, you must start from a point and start in order, don't oil in the east and oil in the west, so that it is easy to miss the brush and the effect will be ugly.

The paint should also change according to the season, try not to carry out indoor latex paint painting in winter, when the temperature reaches minus 5 degrees, the film-forming property of the paint becomes fragile, can not be better combined with the wall, the temperature reaches more than 15, the paint can play a film-forming and waterproof.

The wall paint does not fall off is the desired result of every owner, which not only reflects the quality of decoration, but also the protection of wall decoration. So, what can we do to make sure the wall paint doesn't peel off?

1.Choose a high-quality lacquer material.

First of all, choose a high-quality lacquer. There are many types of lacquer on the market, from ordinary paints to high-quality paints, each with its own special functions and properties. If you want your wall paint to last a long time without fading or peeling, then you should choose a high-quality paint.

This ensures that the painted surface is fully coated and abrasion resistant, and also protects the wall from damage.

2.Use an appropriate brush.

Secondly, you need to use a brush that is suitable for the lacquer material. Different types of lacquer require different types of brushes. If you are using paint, it is better to use a wool brush, and if you are using a water-based emulsion paint, it is suitable to use a rubber brush.

To ensure that the wall paint does not fade, be sure to choose a suitable brush.

3.Primer.

Before painting the wall, you need to add a layer of primer. Primer is the first line of defense to protect the wall, which can help the paint adhere to the wall and increase the durability of the paint. As long as the primer is in good condition, the adhesion of the protective paint layer to the wall will be stronger.

4.Adequate coating.

The amount of paint applied directly affects the quality of the wall paint. If there is too little, the paint layer will be too thin to protect the wall; If there is too much, it will cause the paint to dry for too long, the adhesion is poor, and it is easy to peel off. Therefore, when painting, it is necessary to determine the appropriate amount of coating according to the nature of the paint and the condition of the wall.

In short, to ensure that the wall paint does not peel off, you need to start with many aspects such as materials, brushes, primers, and coating amounts. In the decoration process, we need to carefully select and use materials, adopt the correct painting methods and techniques, then the effect of the wall paint is naturally very ideal.

It is necessary to brush a primer, the primer mainly plays a role in anti-alkali sealing, increasing adhesion, if you do not brush the primer, the alkalinity of the wall is heavy, it is very likely to be alkaline, affecting the decorative effect.

Wall paint is one of the main decorative materials used for wall decoration in home decoration. It accounts for a considerable proportion of the cost of basic decoration. It is very important to choose a good quality wall paint, in order to achieve the purpose of bonding, the main component of wall paint is synthetic resin, which can be firmly bonded to the wall.

Not necessarily, because all kinds of lacquer are composed of film-forming substances (various resins), solvents, pigments, desiccants, additives. Ordinary paints usually use gasoline as a solvent, epoxy iron red primer contains a small amount of xylene, dip paint mainly contains toluene, and there is also a small amount of benzene. Spray paint (nitro paint) and its thinner (banana water) contain a large amount of benzene or toluene, xylene, spray paint without protection, the concentration of benzene in the air in the workplace is quite high, and it is extremely harmful to painting workers.

Furniture must be painted, and no matter how beautiful the furniture is, there is no luster. All kinds of paints contain a variety of polluting substances that are harmful to the human body, and attention should be paid to prevent pollution when painting furniture. Paints contain toxic substances such as rosin, benzene and alcohols, which are quite harmful to the human body.

If benzene vapor reaches a certain high concentration, it can cause death. Long-term exposure to benzene can cause chronic poisoning, resulting in leukopenia, thrombocytopenia, bone marrow hematopoietic dysfunction and other diseases. When painting furniture, it contains toxic solvents that continue to volatilize, causing headaches, nausea, fatigue and abdominal pain, and long-term exposure can make people lose their appetite and cause chronic poisoning.

The harm of paint to the human body can occur not only through inhalation in the lungs, but also through absorption. The human body is in direct contact with paint, which can dissolve the fat in the paint, causing cracking and inflammation while also entering the human body. Therefore, attention must be paid to the prevention and control of paint pollution.

When painting furniture, it is best to choose dry weather, open doors and windows, let the air flow smoothly, and reduce the concentration of solvents in the air in the room. Wear gloves and overalls when painting. Immediately after painting, it should be cleaned ** and scrubbed with a mixture of fine yellow sand, sawn and butyl acetate.

The integrated wall material of the cloud era is made of imported oak carbon, because the oak carbon has the function of super adsorption and essence formaldehyde toluene, it is widely used in the field of home decoration in South Korea, and is very suitable for the decoration of high-end residential and commercial places. Integrated wall materials and artificial microcrystalline stone, which is currently the closest to natural stone decorative materials, will be an increasingly scarce substitute for natural stone in the future, which can be widely used in the construction of residential door and window covers. Compared with natural stone, artificial microcrystalline stone has the advantages of easy to be damaged in transportation, simple processing, no special tools, high cost performance, and no radiation.

This is not necessarily, the key is not to paint and get something, otherwise it will not look good.

The paint contains a lot of benzene, and it is recommended to use environmentally friendly materials.

Generally, it is brushed, but it is recommended to use a good paint, or you can choose not to brush.

First, first of all, you can choose wallpaper, wallpaper is no stranger to us, this wallpaper in the process of decoration, the operation is very simple, the principle of wall covering is exactly the same as wallpaper, but the decorative surface is a piece of fabric. Different materials, textures and wallpaper are different. Depending on the size of the wall, the width of the wall hanging can be meters or 3 metersMore than the height of most homes.

Because the width is long enough, a wall or a room can be attached to a piece.

IIDiatom mud is also a good choice for three things, such as activated charcoal, which absorbs moisture from the air and releases it when necessaryPut. The real use of diatom mud is to regulate the humidity in the room, especially in the south. As for the style and pattern, it is not its strong point, this is just another choice, many people will choose this way and way when decorating, the operation is relatively simple, and the effect is very good.

IIILiquid wallpaper is a very large and very common concept. Now there are two kinds of liquid wallpaper, one is latex paint, and the other is special art paint。Patterns are made using latex paint, rubber rollers can be used, and screen printing can be used.

The rubber roller is a bit like a postage stamp, which is printed on the wall in different colors. Screen printing is like graffiti painting. When decorating, it has a mold, and the top of the mold is painted, and if there is no place that has been punched, the corresponding pattern can be drawn.

Fourth, wood veneer is also a very good choice, but the biggest disadvantage of this decoration is that it is more expensive, usually used is a man-made board, the surface is a layer of wood, is a very high-grade material, like most of the houses in the United States are wooden structures, so they will want to use this decoration method for decoration.

The above introduces several decoration methods for you, you can choose according to your preferences.

In addition to painting, the wall can also be pasted with wall paper, which is very simple to operate, and it is relatively easy to replace it later.

In addition to painting the wall, you can also paste wallpaper or wall cloth for your own wall, which is also very good.

I think the wall doesn't need to be painted, and it's nice to hang decorative paintings directly, can you make a whole ** wall?

You can also choose to stick wall covering, and it is also particularly good. Because the wallcovering is stronger, and the color is also more beautiful.

In addition to painting, the wall can also be inlaid with tiles, and can also be pasted with wall cloth and wallpaper, and now the decoration techniques have been very diverse.

If you don't want to make it big because you rent a house, you don't need to shovel it off, and you can directly use sandpaper to polish it and then brush the paint

The mud wall can not be directly painted, and it needs to be treated, as follows:

Base treatment, the new cement mortar wall should not be painted, and it is generally necessary to wait for half a year before brushing the oil. If you have to paint, you can wash the wall with water every 2 to 3 days, and repeat it many times. Before brushing the oil, it should also be coated with 10 20 dilute hydrochloric acid water once to neutralize the residual alkali in the cement mortar layer, and then brush the acid water with water and dry it after a while.

In this way, the surface layer of the new cement mortar will not bite the color, lose the light and roll up after the paint.

It is best to use pig blood and water to make the old cement mortar wall into a rice soup shape, brush it on the cement mortar wall with a row pen, and then scrape the pig blood putty after drying. Generally, the surface dust should be removed before the cement mortar wall is painted, and the cracks, depressions and other damaged places should be filled with gypsum putty.

Painting is also a very critical step, generally the wall can be brushed twice with magnetic paint, the second time to wait for the first time to dry before brushing. The direction of movement of the oil brush during brushing should be left and right and downward brushing, so that the brush is uniform and the joint is not easy to see.
