How to waterproof the exterior wall of a rural self built house

It's best to find a professional team.

There are many ways to waterproof the exterior walls of self-built houses.

1. After the construction of the cement mortar screed layer is directly carried out, it is divided into silo joints of about 6 meters.

The surface layer is constructed with 1:2 or 1:3 cement mortar surface layer, and the joints are plugged with ointment or asphalt in the silo joints.

2. After the construction of the cement mortar screed, the facing brick veneer construction is carried out.

3. For areas with large rainfall, increase the waterproof layer coating construction, and then carry out the decorative surface layer construction.

4. The construction of high-grade decorative coatings is adopted, and the bottom layer has a closed waterproof function.

How to waterproof the exterior wall of a self-built house in a rural area? As a rural person, we will find that the phenomenon of rural people building houses in recent years is very common, and the houses built are no longer adobe houses, but brick and cement structure houses, such houses are much stronger and more durable than the previous earthen houses, but there is still such a problem, that is, the problem of preventing water seepage, although rural people are not like urban people, there is water seepage in the house upstairs and downstairs, but because they are all single-story structures, the house is wet by rain and snow outside all the year round. In particular, the exterior wall is prone to water seepage, so how to solve this problem when building a house?

How to waterproof the exterior wall is particularly crucial. We do waterproofing for the exterior wall house, first of all, the brick wall, wet with water, drench several times, and then smear a thick layer of cement, so that the surface of the wall is very smooth, when the first layer of cement is done, the wall is already very flat, but it is rougher, and then we have to carry out the second operation, that is, to do cement painting again, the second time the requirements are relatively high, first of all, the sand must be fine sand, that is to say, such cement density is high, when it rains, water can not seep in, of course, The ratio of cement to sand should also be increased a lot, pay attention to the second time the cement should not be too thick, otherwise it is easy to crack.

Another method is to paste porcelain on the exterior wall, the effect of sticking porcelain is definitely better than plastering cement, of course, the cost will be relatively increased, so that the service life of the exterior wall is greatly extended, but even so, it is inevitable that there is a phenomenon of water seepage on the exterior wall, and the phenomenon of porcelain falling off will appear after a long time.

Of course, with the development of science and technology, there are also a lot of waterproof materials, for example, I will introduce you to a kind of stucco glue, the glue is smeared on the wall of the exterior wall, which will make the exterior wall form a protective film, so that it is difficult for rainwater to penetrate into the exterior wall, and the operation is quite simple, that is, use a brush to gently paint a layer of protective film on the exterior wall, and then paint the second layer after a period of time, just like a mobile phone film, protect the wall, so that the wall is no longer troubled by wall water seepage, thus greatly extending the service life of the house. Especially now that some farmers have money, the houses they build are like small villas, so it is necessary to protect the exterior walls from seepage to make the houses look more beautiful.

We can also see another phenomenon of worker construction, that is, when mixing the sand, they will add some mortar king or dish soap and the like, of course, the purpose of their addition of these things is to reduce their labor intensity, so that the sand is stirred more evenly, but I still do not approve of this phenomenon, because stirring dish soap or mortar king will greatly reduce the quality of the wall, if it encounters rainy and damp weather, the wall will appear white foam, which is very unsightly, and there is no quality assurance.

Well, I will answer this question briefly, if your home is also building a house, I hope it can bring you a reference, emphasize, when building a house, you must do exterior wall water seepage operations, do not reduce this important step in order to save money.

Waterproof mortar can be used for waterproofing, and the treatment is more practical and simple. First of all, clean the surface of the exterior wall thoroughly, sprinkle some water on the surface and then make the bottom mortar base layer and waterproof mortar layer.

The most important thing is to choose a good material, choose a good waterproof material, try to avoid the situation of making up for a few years, and do a good job in material selection.

Tile sticking, after the tile is pasted, the rainwater will not penetrate in, and it also looks tall.

As we all know, when we build our own houses. Exterior walls must be waterproofed. Otherwise, when it rains, the home will regain moisture, seep water, and become irritable.

Destroying the decoration will affect the aesthetics, and the life of the family is not convenient. Therefore, when building a house, it is necessary to do a good job of waterproofing the exterior walls, if there is water seepage, it will be very troublesome to repair it later. It turns out that this is the most correct way to waterproof the exterior wall, and the house built in this way in the countryside will never leak.

The exterior wall waterproofing should have the basic function of preventing rain and tears from penetrating the wall, and have the properties of freeze-thaw, high temperature resistance, wind load and so on.

Exterior wall waterproofing is generally divided into exterior wall overall waterproofing and node structure waterproofing, and the total waterproofing of exterior walls is well known. It is to completely waterproof the entire exterior wall. Node structure waterproofing is a structural form that is used to block the passage of water and prevent water from penetrating into the interior.

Residential parks are also specifically talking about the content of the node waterproofing structure. So today, let's talk about the problems that need to be paid attention to in the design and construction of the overall waterproofing of the exterior wall and the waterproofing of the node structure.

The whole is waterproof, and there are no external thermal exterior walls. When using paint finishes, the waterproofing layer should be set between the flat layer and the paint finish layer, and the waterproofing layer should use polymer, cement, waterproofing mortar or general waterproofing mortar. When using block finishes, the waterproofing layer should be set between the flat layer and the block-adhesive layer, and the waterproofing layer should use polymer, cement, waterproofing mortar or ordinary waterproofing mortar.

For exterior insulated exterior walls, when using paint or block finishes, the waterproofing layer should be set between the insulation layer and the wall base layer, and the waterproofing layer can be polymer, cement, waterproofing mortar or ordinary waterproofing mortar.

Alkali-resistant fiberglass mesh can be added to the mortar waterproof layer, which should be fixed on the structural wall with anchor bolts. The mortar waterproofing layer should leave a gap, and the spacer should be set at the boundary of different materials of the wall structure. The horizontal lattice seam must be level with the upper or lower edge of the window.

The vertical split spacing cannot exceed meters and must be aligned with the two lines of the door and window frame. The width of the split seam should be 8-10mm, and the suture should be sealed with sealing material. If there is a basement, the exterior wall waterproofing must overlap with the basement waterproofing.

For the exterior wall of a self-built house in rural areas, you can choose to paint a layer of waterproof paint, and then use waterproof paint to paint the exterior wall.

You can paste some wall tiles on the exterior wall or do a good job of waterproofing, painting can do not seepage, and the exterior wall should be selected in the process of construction.

First of all, when we do exterior wall design, we should try to achieve the effect of waterproofing, and we should also pay attention to production and maintenance.

When building the exterior wall in the countryside, you can choose the cultural stone, because the color of the cultural stone is very good, the decorative effect is particularly good, and it is also very cost-effective, you can also choose real stone paint, you can also choose the natural color of the original sand stone, which can make the exterior wall appear very high-end, and it will also be very strong, with more durable advantages.

It will do the trick with high-strength cement.

We all know that for most people now, we actually have a lot of precautions when building a house. If it is not done well, it is likely that there will be water leakage, so some people will have such doubts, that is, in the rural self-built houses, how to deal with the exterior wall to achieve no water seepage? To answer this question, it seems to someone that when painting exterior walls, for example, we need to do two jobs.

At the same time, do not come into contact with other objects, let's take a closer look.

1 Two workers are requiredWe all know that if you want to build a self-built house in the countryside, it is actually difficult to do it, if you don't do it well, there will often be some impressions, and you feel very uncomfortable to live in. There will even be water seepage, so that you will feel that the whole home is damp, so if you want to deal with the exterior wall without water seepage, we need to paint the exterior wall twice, the thickness of the first time is relatively thick, this is mainly used for leveling, ** Eat, we will choose to use fine cement mortar, its thickness is relatively thin, this is mainly used for waterproofing.

2 Avoid contact with other objectsWe all know that for the way of self-repair in the countryside, we should avoid contact with other objects, that is to say, there should be a process between the two buildings, and the walls of the two buildings should not be next to each other, so that if it rains or there is water, there will be infiltration.

In the process of building a house, the cement slurry can be built on the exterior wall without any gaps, and at the same time, the shelves and pipes should be docked, and finally the plastering is in place, and then sprinkled with water, and the maintenance can be done for three days.

You can apply a layer of cement to the exterior wall, then a layer of waterproofing, then a layer of cement, and another layer of tiles on the outside, so that there is no water seepage.

It is necessary to prepare for waterproofing, to lay a good foundation, and to apply a layer of cement on the outside, or to use a special treatment.

In rural self-built houses, when the exterior wall is finished with paint, the waterproof layer should be located between the leveling layer and the paint finishing layer, and the waterproof layer should be made of polymer cement waterproof mortar or ordinary waterproof mortar;

Self-built houses in rural areas usually start to be waterproofed after the completion of hydropower projects. When doing waterproofing, you should brush it several times, do it carefully and carefully, and finally put the water to test it to see if there is water leakage. Before brushing the first waterproof coating, ensure that the construction site is clean and dry, and the waterproof coating should be full, without omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

The coating height is consistent, and the thickness should meet the requirements of the product.

Brush the waterproof paint for the second time, pay attention to the first.

First, the second waterproof coating needs to have a certain time interval, and the second time can only be carried out after the first coating is dry, and the specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced.

Other facts about waterproofing.

After doing the waterproofing, you must do the closed water test, the closed water test, the water at the highest point of the ground can not be less than 2 cm, keep it for at least 24 hours, and observe that there is no leakage before it is qualified. If there is a leak, it needs to be redone, and it must not be negligent. Substrate treatment, cleaning, leveling layer, bonding layer, detail additional layer, acrylic waterproof layer, water storage test, protective layer construction, secondary water storage test.

1. According to the on-site situation, clean up the original exterior wall paint of the waterproof part of the base layer, especially the broken and loose parts of the base layer and completely clean it.

2. Clean the paint, dust, oil stains and stains on the surface of the waterproof base layer and bond the waterproof material firmly.

3. On the basis of clean base treatment, diluted with high-grade silicone waterproof coating and water at a ratio of 1:2, and then mixed with high-grade cement to make plaster, and the sand hole, honeycomb and cracks are treated in detail.

4. When repairing irregular cracks, cracks over 2mm can be repaired with filament non-woven fabrics and special coatings for silicone exterior walls to avoid the expansion of cracks.

5. Strengthen the treatment of important parts such as the perimeter of the window, the bottom of the eaves, the embedded parts, and the wall pipe.

6. After the base layer to be repaired is treated and dried, the engineering parts are painted with high-grade environmentally friendly silicone interior and exterior wall waterproof coatings according to the standard.

7. Stir well with waterproof materials. Click to make an appointment for a professional master to come to the door for maintenance.

There are generally three ways to repair wall leakage. One is to redo the exterior wall waterproofing. This method requires removing all the attachments and decorative layers of the original exterior wall, and then making the waterproof layer thick, and then redecorating.

Another method is to treat external leakage internally, which requires the selection of a high-tech plugging unit and maintenance from indoors. The only thing to keep in mind with this method is not to invite teams that are overloaded. Otherwise, the quality cannot be guaranteed.

Another short-term waterproofing effect is to spray a layer of waterproofing paint on the exterior wall. The advantage is that the cost is low and it is easy to construct. The disadvantage is that the shelf life after repair is generally 3-5 years, and the wall will be very ugly after 3 years, which will affect the appearance of the whole building.

1. According to the actual situation of the site, clean up the original exterior wall paint of the waterproof part of the base, especially the broken and loose parts of the base to completely clean up the hard foundation.

2. Clean the coating, dust, oil stains and stains on the surface of the waterproof base layer to make the waterproof material firmly bonded.

3. On the basis of clean base treatment, diluted with high-grade silicone waterproof coating and water at a ratio of 1:2, mixed with high-grade cement to make plaster, and detailed treatment of trachoma, honeycomb and cracks.

The ground of rural self-built houses can be waterproof concrete, membrane waterproofing, coating waterproofing and concrete mortar to waterproof the foundation.

The moisture-proof layer of the ground is usually constructed with waterproofing mortar, which is mixed with cement mortar and waterproofing agent in a certain proportion and evenly applied (about 2 3 cm thick) at the position where the moisture-proof layer is made. It is also possible to install leather bricks and lay a layer of leather bricks with waterproof mortar.

The moisture-proof layer of the ground can also be made of linoleum, and the construction steps are: first apply mortar to level the moisture-proof layer in the place, and then lay a layer of linoleum. Before construction, the size of the linoleum must be determined and cut well, so that there will be the best moisture-proof effect.
