Why does the wall surface become hollow and moldy and cracked? How to decorate without spending money?

Analysis of the causes of wall hollowing cracking.

Due to the improper ratio of the wall powder layer, the structural performance and adhesion of the wall itself are poor, and the hollowing and cracking phenomenon is easy to occur in the later construction; 2. Apply the second layer of putty before the putty is completely dry, the water in the wall cannot be volatilized in time, and it is easy to hollow and crack in the later stage; 3. The reserved expansion joints are insufficient when tiling, and the bricks are prone to hollowing and cracking after expansion.

The amount of cement used is insufficient.

In general, the ratio of wall cement mortar is made according to 1:3. If the amount of cement used is too low in order to save materials less than this standard, its structural strength will definitely be affected. The aforementioned sanding of the wall is caused by this kind of factor.

tiled walls. Before the construction of wall bricks, the base layer must be cleaned first, and then the bricks must be soaked in water until there are no bubbles. Finally, when pasting tiles, it is necessary to reserve space for tile expansion, and after pasting tiles, the tiles on the wall must be fully ventilated to avoid tile expansion, hollowing, warping, etc. caused by other reasons.

Painting the walls. The steps of wall painting include basic treatment, putty brushing, polishing, primer brushing, topcoat brushing, and maintenance. Be careful at every step.

When scraping putty, the walls must be dry. When polishing, you'll need to use finer sandpaper to avoid breaking the walls. When applying the primer, you can add a little more water to make the paint softer, and at the same time level the uneven places, while the topcoat should add less water, so that the effect will be better.

What if the walls are damp and moldy?

Damp and moldy walls not only affect the aesthetics, but also endanger the health of family members. It is necessary to deal with it in a timely manner!

Mold treatment method:

1. When there is mold on the wall, you can first brush off the mold stains with a dry toothbrush, and then gently wipe it with a soft cloth dipped in alcohol to dry the wall and prevent mold breeding.

2. Use bleaching powder, add water at a ratio of 1:99 to make a water agent, pour it into a spray bottle, and spray it on the moldy wall, which can solve the problem of the moldy wall. If the weather is still wet, you can press 1:with bleach and water

20 proportions smeared on moldy walls. After the wall is dry, sandpaper the wall is sanded, a layer of waterproof primer is brushed, and finally a layer of latex paint is brushed.

Why: 1. Due to the improper distribution of the proportion of the wall powder layer, the structural performance and adhesion of the wall itself are poor, and the later construction is prone to hollowing and cracking; 2.The second layer of putty starts before the putty dries.

The water in it cannot be volatilized in time, and it is easy to hollow and crack in the later stage; 3. When tiling, the reserved expansion joints are not enough. Tiles are prone to hollowing and cracking after expansion. How to load:

When selecting construction personnel, qualifications should be the main thing. Find a reliable person to pretend not to spend money in vain.

It is because the windows are not opened often for ventilation, and the home is relatively humid, so it will lead to mold and cracking. When decorating, you must choose some more professional decoration teams, and also choose some more professional workers, so as not to spend money in vain.

The hollow mold and cracks on the wall may be caused by the unreasonable material ratio in the process of decoration. When decorating, you must choose a better decoration team.

If you find that mold spots are starting to grow in your house, if you don't stop the growth in time, it may cause this to happen throughout the house. So today I will tell you how to prevent the growth of mold. First of all, you need to keep the walls and furniture in the room clean and hygienic, and reduce the nutrients needed for the growth of mold on the walls.

Second, you have to take temperature control, and the conditions for mold to multiply are that it is achieved by controlling the temperature and humidity of the building and the maintenance materials, so as long as you keep the temperature of the wall at a certain level, it will not grow.

The first possibility is the infiltration of rainwater, which may enter the room through cracks in the wall during the rainy season or rainy days, causing dampness in the surrounding area, and mold will be found on the ceiling after a long time.

It may be because it is too humid, and the climate is humid, so it causes mold in those places.

The walls and ceilings of the newly renovated house are moldy due to water leaks.

After a few years of renovation, cracks appear on the walls of the home, and the phenomenon of hollowing, even if the wall fades, falls to a large extent, because during the decoration process, the broken walls are used to reconnect, the primer is not enough or dries too quickly becomes a fake phenomenon, and the house exchange machine is too large. Want to solve, whether it's rework, or keeping the home ventilated.

1, Broken walls, in home improvements, we can easily face removal or wall attachment to change the wall. Then there is the construction of the new old wall due to the same construction point. With the shortage of thermal expansion, the longer and easier it is, the problem of wall cracking occurs later.

This problem is generally short-term re-brushing and can't see it. But it will still show the long term. It is advisable to apply wall stickers or wall cloth to cover it.

The problem of painting the wall primer will have a hollow drum. We all know that brushing the wall needs to be three steps, brushing, putty, and top coating. In the process, each step is dry and the next is possible.

If there is no drying in the putty, just brush the face paint, which can easily lead to hollowing or peeling. Sometimes it doesn't dry out, but it's too fast. Normal dry paint should be a sealed window and a month to dry.

But sometimes, in order to catch up with the project, the windows are opened and the windows are opened, and at the end of seven to eight days, I have reached the hidden danger.

3. Avoid moisture, more ventilation in life, this problem occurs at home, in addition to maintenance, it is also necessary to improve the effect of ventilation at home. Avoid getting too damp in your home, which can cause hollowing out and peeling.

Especially on weekdays, dry dragging must be done after moving, and not damp, such as water vapor, many of which are absorbed by the walls.

Usually in this issue, there weren't many fixes at the time. Because it was repainted today, it was less than a year and a half old, and there was also a crack or hollow drum. Unless you choose to shovel wall paint, wipe down the walls. Otherwise, it's just a palliative approach.

Once there is a problem with the wall, the most fundamental method is to remove it and repaint it.

If the wall is only cracked with latex paint and putty, then directly remove the surface layer, scrape the putty, and then paint the latex paint after the putty is dry. The hollowing rate reaches a certain degree and a certain area, and the plastering layer will fall off in the future, because there is a problem with the material ratio at that time. And moisture-proof, you can buy some leak-proof glue and paint it directly on the surface of the tile, or in the gaps of the tile.

In the process of decorating a living room, the construction of walls is a relatively important process, and there are many beautiful procedures. If you pay attention, after a period of life, there will be problems with hollow drums, which will greatly affect the effect of the decoration and the beauty of the house. It also makes a lot of people feel very anxious.

Of course, if there is an empty wall problem in the house, it should be dealt with in time. After two years of renovation, the walls were hollowWhy does it happen?

After two years of renovation, the walls were hollowWhy does it happen?

First of all, there are many factors that go into this situation. In general, when the undercoat is applied or the primer is not cleaned, the walls are usually not treated as required. Therefore, the plaster base should be checked before placing the tiles.

Regardless of whether the requirements are met or not, when laying the pavement, the use of mixed cement mortar or cement mortar 107 on the back of the tile, and the striking of the tile with a hammer handle or a soft hammer, the cement mixture should cover the back of the tile and firmly adhere to the base layer of the wall.

Secondly, of course, before paving, the bricks are not soaked or lack enough water can cause this problem. In general, the bricks should be soaked for more than 2 hours before paving so that the tiles are completely absorbed, dry or cleaned. If the brick body is not saturated, it will prematurely absorb the water molecules in the mortar, which will cause the mortar to shrink and appear empty, which will also affect the strength of the joints.

After two years of renovation, the walls were hollowWhat to do.

After two years of renovation, the walls were hollowFirst of all, for some normal hollowing conditions, it is recommended to remove the sand ash first, and then re-use the fast ash to compensate for the collection of putty dust after drying, but some hollowing causes are difficult to excavate due to location and other reasons, for example, it is more difficult to eliminate the gap between the concrete cover and the base layer. Some of the most expensive stones, hollow drums between tiles and base layers, and the economic loss of stones after chiseling is significant.

After two years of renovation, the walls were hollowSecondly, for some wall drums that are difficult to recover, it is recommended to use the perfusion repair method. It has a fast operating time and does not damage the base, especially in underground garages, factories and other places. The construction process does not affect the owner.

A more comfortable way.

After two years of renovation, the walls were hollowWhat are the dangers?

First of all, it will have an impact on the general aesthetics. Generally speaking, the area of the empty wall will cause cracks in the paint layer, just as the scars on the face are very noticeable and will also affect the effect of using the liquid, and there is some safety. The hollow drum area is larger, and the longer hidden danger will be lowered by gravity.

Small losses are tiles and broken furniture. If there were people down there, it would be serious.

You can get it for free

It is because it often rains, and the weather is very humid, or the insulation layer of the wall is not good enough, and the quality of the wall is not good, and it may be the way of rain, and it is the phenomenon that the wall is cold, so it will lead to moldy ceiling on the wall.

It is likely that the waterproofing of the wall is not good enough, so you should re-do the waterproofing to make your home drier.

It may be that there is a lot of rain, so some rainwater seeps in from the roof and walls, which causes the home to be very damp, and there will be some moldy conditions.

Causes of mold.

Lakeside or coastal, continuous rainy season, basement ventilation environment humidity, indoor and outdoor temperature difference, indoor air condensation on the wall to form condensation, so the wall surface is damp, causing mildew.

The water supply pipes and pipe walls are damp, the external rainwater enters the room, causing cracks and moisture in the wall, and the baffle or poor sealing at the junction of the baffle and the balcony may lead to rainwater entering the interior from the outer wall, causing the wall to become moldy.

The room cannot be kept ventilated for a long time and is not clean.

It may be rainwater seeping in, and there are many rainy days in the rainy season, and rainwater enters the room through the cracks in the wall, causing dampness around the windows, and mold will appear after a long time. There is also the external wall insulation is not enough, if the insulation layer of the wall is not done well, it is easy to appear that the wall is cold, and the water vapor in the house becomes water droplets, and the wall is easy to be damp and moldy.

Every year in June and July, the rainy season begins, and there is a proverb that says; "The rain hits the yellow plum head, and there is no sun on the 45th" to describe the plum rain, it can be said that the rain continues to be continuous, and the temperature, high humidity and humidity are the main characteristics of the plum rain. The rainy season makes people feel that the quilt and clothes seem to be able to wring out the water in minutes, not to mention the moldy walls of the home.

In the rainy season, many families will encounter this kind of situation, the degree of mold on the wall is large and small, and the owners and friends usually buy new paint back for repainting, which is not only tired and half dead, but also the cost is not cheap.

1.Once you find a trace of mold on the wall, you should immediately eliminate the mold by using a toothbrush to remove the mold area, and then wipe it with a soft cloth soaked in alcohol, which can effectively prevent the wall from drying out and prevent the growth of bacteria.

The mixing ratio of bleach and water must be 1:99, pour it into the watering can and spray it on the moldy wall area, wipe the wall with a dry rag, and then clean it with some water, and wait until the wall is completely dry before brushing with anti-mildew paint.

2.Buy some lightweight professional waterproof repairs on the market and spray some wall crevices on the wall. If the moldy area of the wall is not serious, you may wish to use 80% alcohol directly to wash the favorite wall, and be sure to keep indoor air circulation afterwards.

Common tips to prevent wall mold.

1.When you open the windows indoors at home, you must pay attention to the air circulation, let the walls blow and dry.

2.Commercially available desiccant can be used to remove moisture from the room.

3.Families with conditions can also buy a dehumidifier, and they can also remove indoor moisture at home.

4.During the decoration, the owner can let the construction master coat the wall with impermeable liquid, so that the wall forms a colorless and transparent waterproof adhesive film layer to prevent foreign moisture from penetrating in, and effectively prevent the wall from being damp and mildew!

Causes of mold on the wall:

1.Rainwater seeps in.

During the rainy season or rainy days, rainwater enters the room through cracks in the walls, causing dampness around the windows, and mildew will appear over time.

2.Insufficient insulation of exterior walls.

If the insulation layer of the wall is not done well, it is easy to appear that the wall is cold and cold, and the water vapor in the house will become water droplets, and the wall will be easy to be damp and mildew.

3.Waterproof is not good.

If the waterproofing of the ceiling surface is not done well, there will be water leakage and mold.

4.Environmental factors.

Usually, if we don't pay attention to ventilation when we live, the indoor humidity will be too large, and the wall will be easy to get wet, resulting in moldy on the wall. In addition, the summer time in the south is long, the air humidity is high, and the air in the coastal areas is humid, so the wall is also prone to mold during the rainy season in the south.

Solution:1Simple handling.

If there is only a slight mildew on the surface, we can use a toothbrush to brush off the mildew, then take a rag dipped in water and wring it out and wipe it gently.

2.How to deal with seasonal reasons.

If this is the case, we should not rush to repair it first, but wait for the water on the wall to evaporate before painting and repairing.

3.Caused by insufficient insulation measures.

First of all, we need to determine whether the lower wall has been insulated, and we can make a judgment by gently knocking on the wall. If the sound is empty after tapping, it means that the wall has an insulation layer, and if the sound is dull, it means that the wall has not been insulated. If there is an insulation layer, it is necessary to check whether there are cracks in the exterior wall of the building, if there are no cracks, it means that the insulation material is not good, and it should be replaced, which is the best method.

4.Replace interior wall paints with better waterproofness.

When the wall is dry, we can repaint it with a waterproof coating.
