How about waterproofing with waterproof cement indoors

You are talking about polymer cement waterproof coatings, indoor use of polymer cement coatings to do waterproofing is OK, it is best to choose the right waterproof material according to various factors in different parts is the best. It is recommended to use the elastic environmental protection coating HG203 waterproof sealing coating for pipes, floor drains and other parts that are prone to problems, and the effect is better if the ground is also used with this coating, and the wall is made of polymer cement waterproof coating.

If the bathroom is not equipped with the function of bathing, the height of the wall waterproof layer can be 300mm; However, if it involves bathing, it is necessary to return to a height of meters to prevent splashing water droplets and water vapor from seeping into the wall through the tiles and gaps, causing wet stains on the wall next door.

The construction method is as follows:

1. Clean up the base layer, remove the original waterproof layer made by the developer until the original base layer is exposed, and then clean up the debris and floating soil. Then sprinkle water to make the base surface fully moist to saturation.

2. According to the weight ratio of 1:2, the waterproof slurry is made by mixing cement with waterproofing agent, and the construction is painted with a brush, with a thickness of 2mm.

3. According to the weight ratio of 1:2:5-6, mix cement and sand with waterproofing agent to make waterproof mortar, scrape with a mud knife, and the thickness is 16mm.

Note: The interval between the waterproof slurry and the waterproof mortar should not exceed 30 minutes, and the surface drying of the waterproof slurry should be used as the standard for the second construction process.

4. If you need to paste tiles, you can turn off the water after the waterproof mortar solidifies and can be put on people. The water is turned off for 24-72 hours. If there is no leakage, the tile can be pasted; If leakage occurs, find out the leakage point, cut it into a V-shape, and re-install the waterproof according to the specification construction.

5. If you don't need to paste tiles, you should paint the waterproof slurry again, and after the surface is dry, sprinkle and cure (according to the sprinkling curing process of ordinary mud work).

6. Other precautions: the cement should be made of 425 mark, and the drier and cleaner the sand, the better; Yin and yang corners, wall roots, and sanitary ware should be wiped into R corners; The overall mortar layer should be smoothed and compacted, and no cracks should appear.

The use of waterproof coating, must be painted on the cement board cement mortar to be dry and solid, the effect is good, ** high, the use of waterproof film, remember that the inside and outside are connected with static cement, because the film is almost flat with the wall after drying, the indoor is generally used, the use of coil material, the general requirements must be pasted bricks to cover the ugly, the material thickness is obvious throughout the effect, more use and outside the house,

To do waterproofing, you need to do it on the surface of the water, and the black gold steel penetrates the crystalline waterproof, and you can do it yourself.

The problem cannot be solved, and only by spraying waterproofing agent on the outside of the roof or exterior wall so that the water cannot penetrate into the wall and flow away can the problem be completely solved

Which waterproof material is the best, after listening to the host's analysis, I found that I was not lightly pitted.

What materials are generally used to decorate the house.

There is no best waterproof material for waterproofing, only more suitable waterproof materials, waterproof coating is the main thing for the bathroom, and waterproof membrane is the main material for the roof.

Answer 1, polyurethane asphalt coating glue This type of glue is very effective in the waterproof treatment of roof leakage, exterior wall water seepage, balcony water seepage, etc., because it has high elasticity and high strength, can be extended arbitrarily and will not leave water leakage gaps, and has the title of "leakage king". Moreover, this kind of waterproof adhesive is not an oil-based formula, there are no harmful substances such as benzene solvents, and there is no harm to the human body and the environment. At the same time, it has a long service life, not only good waterproof performance, insect release, anti-corrosion, cracking and other properties are also very good, and it is economical, if you are still thinking about what glue to use for waterproofing, this coating glue is worth recommending.

2. Plastic steel mud waterproof glue First of all, this type of glue is generally divided into waterproof glue used on the surface and gaps of wall tiles and waterproof glue used in the underground reinforcement of ceramic tiles to prevent leakage, which is very convenient to use, and only needs to plug the gaps or loopholes with cement in the place where waterproof treatment is required, and then brush the plastic steel mud waterproof glue, and the amount is added or subtracted according to the actual situation. And the construction period is very short, and it can be restored to normal use after a few hours. At the same time, this kind of waterproof adhesive is non-toxic and environmentally friendly, almost does not contain volatile toxic substances, and may have some sour taste, but it is only the taste of acetic acid, so there is no need to worry about it.

Hello, a small piece of my foot bathtub fell off and needs to be glued with waterproof glue, what glue is better.

Question: Do you sell them at hardware stores?

Cement can achieve a certain waterproof effect, but it cannot completely replace the waterproof material.

For example, if you want to make a bathroom or roof waterproof, you can't use cement. However, if there is a problem of water leakage in the corner of the wall and other places, we can wipe a sedan car with some cement in the leaky place, which can increase the waterproof effect, but can not achieve the fundamental waterproof purpose.

The position of the corner of the bathroom wall is prone to the problem of water leakage and water seepage, although the waterproof material has been brushed, but you can also smear some cement in the corner of the wall, so as to form a small slope and increase the waterproof effect, so the cement can be waterproof, but it can not replace the waterproof material.

Introduction of cement

Mud: Powdered hydraulic inorganic cementitious material. After adding water and stirring, it forms a slurry, which can be hardened in air or water, and can firmly cement sand, stone and other materials together.

The mixture of early lime and pozzolana was similar to that of modern lime pozzolana cement, and the concrete made from cemented crushed stone was not only strong when hardened, but also resistant to the erosion of fresh or salt water. For a long time, as an important cementitious material, it has been widely used in civil construction, water conservancy, national defense and other projects.

Cement is usually used in general civil engineering and construction projects. General cement mainly refers to: GB175-2007 specified in the six categories of cement, namely Portland cement, ordinary Portland cement, slag Portland cement, pozzolana Portland cement, fly ash Portland cement and composite Portland cement.

Cement waterproofing is a slip-back that refers to the waterproofing effect achieved by applying a layer of cement mortar or cement concrete. Cement waterproofing is generally suitable for pools, water tanks, roof stoves, basements and other places that need to be waterproofed. Here are the recommendations on how to choose cement waterproofing:

1.Choose a good brand of cement: When buying cement products, you should choose products with a good brand and stable quality. Choose a formal channel of building materials market or professional building materials store to buy.

2.Choose the cement that is suitable for waterproofing: There are many types of waterproofing cement, such as waterproofing cement for basements, cement for roof waterproofing, etc. It is very important to choose the right type of cement for the place where you need waterproofing.

3.Choose appropriate waterproof materials: When carrying out cement waterproofing, it is necessary to choose appropriate waterproof materials, such as waterproofing agents, waterproof materials, etc. These mating materials can improve the waterproofing effect very well.

4.Choose cement according to the construction method: Choose different cement according to your construction method. Some cement can be sprayed, while others need to be applied with a brush or roller.

In short, the purchase of cement waterproof materials must be careful and careful, only when the right product is selected can a better waterproof effect be achieved. If you don't know how to deal with waterproofing, it is recommended to contact a professional anti-concealment water construction company to ensure the quality and effect of waterproofing projects.

Cement is waterproof, but its ability to repel depends on its thickness.

In general, the thickness of the cement reaches7-8 cm and aboveIt is completely waterproof to achieve the effect. For example, in my hometown and even many self-built houses in rural areas, the roofs are covered with cement, and no other waterproof coatings are added, which can also achieve a good waterproof effect, and it is not easy to break, because the thickness of the cement is thick enough.

But if it's too thin, the waterproof effect is very poor. SellingFor example, if we simply brush a thin layer of cement in our residential area, it will not be able to achieve the waterproof effect. And you must use professional waterproof coatings.

In addition, compared to the wall, the toilet floor is more likely to be affected by subsequent construction, and after moving in, it may be more frequently eroded by water, so the waterproof protective layer of the toilet floor should be covered with professional waterproof coating and rolling material!

Cement is often used for the surface of a building or for the interior, but it cannot be used for waterproofing.

Waterproofing usually uses special waterproofing materials such as asphalt, ointment, polymers, or cement-based waterproofing coatings. These coarse materials form a tight backing layer that prevents moisture and other liquids from penetrating into the building's foundation.

The main use of cement is as a kind of building material, such as for making walls, floors, roofs, etc. In some cases, such as in basements or underground passages, cement can also be used for waterproofing. However, in this case, a special waterproofing material is used, not cement.

Therefore, cement cannot be used for waterproofing.

Dear, hello, I am glad to answer for you that waterproofing can be done by yourself with cement Answer: There are still certain construction requirements for waterproofing, especially when the cement is not dry, it is definitely not possible to do waterproofing, and waterproofing can not achieve the corresponding use effect. In the case that the cement has not dried out, the water will lead to the thermal expansion and cold shrinkage of the building, and it is easy to lead to the aging or failure of the waterproof layer, such as the bathroom or the kitchen are required to do the corresponding waterproof measures, if you do not do waterproofing, then the downstairs is very easy to leak, which will also affect the residents downstairs, in addition to the roof, the underground building also needs to do a good job of waterproofing.

Decoration is a key project in the family, toilet as a hidden project, its particularity and complexity, waterproof coating at home is how to do, some owners are not very clear, the toilet because of more water, every day in a wet state, decoration waterproof quality problems, and when the toilet screed is done to do the screed layer to be fully dry, the next day sprinkle water proper maintenance; The water should not be too much, and the waterproof construction can only be carried out after the ground is fully dry, which brings a lot of inconvenience to daily life.

<> decorate the bathroom, it is very important to choose waterproof coatings, the base layer should be clean, and the wall before doing waterproofing is basically the mortar layer that the developer wipes, because there was no fine decoration at that time, there will be some uneven places metope, metope rough can not do waterproofing, waterproof effect is not ideal, even if this situation is done, use Jinyu ground leveling mortar, evenly leveling metope and the ground. First of all, the layout of the toilet water pipe should be reasonable and should be installed on the same plane as much as possible. If the water pipe is uneven, the thickness difference of the screed layer will be too large, and the cement mortar that is too thin above the water pipe will be leveled.

It is easy to crack, which is not conducive to waterproof construction.

Ground leveling mortar is a dry powder coating, add an appropriate amount of water in proportion before use, stir evenly to build, before the wall leveling, gently pour a layer of water, so as not to dry the wall, absorb the water in the leveling mortar, resulting in the early strength of the wall is not good, there will be peeling, cracking, falling off, etc. When the moisture on the wall is uniform, the wall can be leveled with leveling mortar. After drying, brush waterproof paint and so on after drying and then brush waterproof coating, wait for dry next, do a closed water test, generally one day can be, go downstairs to see the word let the bricklayer smear a layer of thin ash to protect the ground.

Do a detailed interpretation of the problem, I hope it will help you, if you still have any questions, you can leave me a message in the comment area, you can comment with me more, if there is something wrong, you can interact with me more, if you like the author, you can also follow me, your like is the biggest help to me, thank you.

1. Brush the waterproof paint for the first time. Before construction, ensure that the construction site is clean and dry, and the waterproof coating should be coated with no 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.

2. Brush the waterproof paint for the second time. Note that there needs to be a certain time interval between the second waterproof coatings, and the second pass can only be carried out after the paint is dry, and the specific time depends on the coating. If the interval is too short, the waterproof effect will be greatly reduced.

3. Lay a protective layer. In order to prevent the subsequent construction from damaging the waterproof layer, it is necessary to lay a protective layer on the surface of the waterproof coating. The protective layer should be completely covered with the waterproof layer, no omission, firmly combined with the base layer, no cracks, no bubbles, and no falling off.

4. Closed water test. During the closed water test, the waterline at the ground point should not be less than 2 cm, and it should be stored for at least 24 hours, and it should be qualified only after observing that there is no leakage. If there is a leak, it needs to be redone, and you must not be negligent.

5. Grassroots treatment, cleaning, leveling layer, bonding layer, detail additional layer, acrylic waterproof layer, water storage test, protective layer construction, secondary water storage test.

Second, what are the key points of waterproof construction.

1. During the construction of the waterproof layer, it is necessary to ensure that the waterproof layer is completely attached to the base layer, so before construction, the surface must be cleaned up, and there can be no water or oil stains with dust.

2. The waterproof layer is generally recommended to be coated with two layers, and each time it needs to be completely dried before the next link can be continued, otherwise there may be a hollow drum inside the waterproof layer, which will affect the service life and effect of the waterproof layer.
