Which prawn knows how to judge the construction quality of home waterproofing

Waterproofing is usually not easy to see, because it is done inside the wall, and the outside has to be tiled or painted, so it needs to be supervised when the wall is decorated. Otherwise, if there is a problem in the future, the wall will be knocked out and redecorated, which is a great waste. My experience in judging methods is:

1. What waterproof material is used first, and whether it is a well-known brand; The more famous ones in the country should be Degao and Oriental Yuhong.

2. The waterproof material bought is ** or copycat; I recommend going to a specialty store to buy it, now fakes are everywhere.

3. Whether the construction is serious, whether it is casually painted; There are two methods, one is to strictly supervise and prevent workers from missing brushes, but because the waterproof color is very similar to cement, it is a bit difficult to control; Another recommendation is to buy color waterproof materials, more intuitive and trouble-free, my friend has used Degao's color waterproof, the color is very conspicuous can be easily checked.

It's just to do closed water experiments and water test experiments. The ground is watered for 48 hours, and the wall is drenched with water (all must be done before the tiles are paved), and the inspection is not leaked and qualified. If you want to do high-quality waterproofing, you should first ask a qualified waterproof company to do it, sign an after-sales maintenance contract, and then use big brand waterproof coatings, such as Leibangshi and other brands.

Of course, it is to do a water test, block the floor drain, etc., and put the water depth of 25 30mm to observe for 24 hours to see if the water level drops.

Or go downstairs to see if there is any water on the roof of the shed.

After the waterproof construction is completed, fill the waterproof area with water first, and observe it every other day or half a day to see if there is water leakage. Generally, the water release is only for a maximum of three years.

There are generally several conditions for the quality of waterproof materials: 1. The physical properties of the material are good, such as tensile strength, elongation at break, high temperature resistance, low temperature resistance, low temperature resistance, water impermeability and aging resistance, etc., which are better than those of the same type of materials. 2. Good waterproof adaptability to a certain part of the building.

For example, the membrane is very good for paving a large area of roof, and it is useless to use it in toilets and bathrooms and wall waterproofing. The base surface with a small area and many uneven concaves is where the paint comes in. Another example is concrete rigid waterproofing, which is most suitable for basement walls and bottom plates, if the large-span roof is also rigidly waterproofed, it is not only impossible, but also shows that the design is unreasonable.

3. Give full play to the characteristics and properties of materials. If the combination of waterproofing membrane and waterproof coating can do a good job of roof waterproofing, it is good for planting roofs, and if it is used in roofs with complex shapes, it will be useless. The selection of materials gives full play to the strengths of the material, avoids its shortcomings, and gives full play to the elders is a good material.

Waterproofing coatings and waterproofing membranes like Soprema have a very good reputation in the industry, and they are very cost-effective.

1. Query the anti-counterfeiting code.

Querying the anti-counterfeiting code is the most direct and effective way to identify. Although now counterfeiters will also set their own query ** and query barcode, but some well-known brands of waterproof coatings have a product authenticity query system on their official **, the authenticity of the query code is impossible to imitate, and can only be queried once. In addition, you can also communicate with customer service on the official website and mobile phone SMS inquiries.

Second, look at the outer packaging.

Generally, well-known brand products have certain requirements for the packaging of products, and the exquisite external packaging not only represents the corporate image, but also promotes the products to a certain extent. **The outer packaging of the waterproof coating of the packaging is bright in color, the handwriting is clear and not blurred, and the production date, service life, name, place of origin, etc. are marked in the specification.

3. Weighing.

At present, many waterproof coatings on the market will be a little different from the weight indicated on the barrel, and consumers can weigh them on the spot when purchasing to avoid being blinded.

Fourth, odor identification.

At present, the two-component cement-based waterproof slurry on the market is more stable than the waterproof performance of the single component, and secondly, the liquid material in the high-quality waterproof slurry has a faint smell, on the contrary, the inferior waterproof coating will have a strong and pungent smell.

5. Check the waterproof effect.

Taking polymer waterproof materials as an example, the product can remove the rubber from the wall and floor with a knife, and it will not be broken when folded in half, and it is extensible. Many shoddy and counterfeit products are in the form of powder, which is difficult to remove from the wall and will break when folded in half.

Now the waterproof materials selected for home waterproof decoration are generally polymer cement-based waterproof coating slurry, that is, the name of the building materials market is: general-purpose, flexible, JS, GS waterproof coating paste, this kind of product is non-toxic, harmless and environmentally friendly, simple and fast construction, can be constructed on a wet base surface, strong waterproof effect, long service life, and strong adhesion to the cement base surface, moderate and significant characteristics. It is recommended to choose a brand with good quality and good reputation, such as:

Lei Bangshi, JCDecaux, Oriental Yuhong, etc.

Generally, the products of large brand companies have anti-counterfeiting labels, and the query on the anti-counterfeiting label can be queried, and the production company can also check the authenticity.

Leibangshi - home waterproofing expert.

Household waterproof materials are mainly used in the bathroom, to choose green materials, to avoid home decoration pollution, the choice of JS composite materials or cement-based permeable crystallization is good, Wanren waterproof.

There are many types of waterproofing on the market now, and the Swiss Sika is also good.

With js or waterproof treasure, the waterproof treasure I am talking about is pure powder home and add water to huo.

When the house is decorated, the bathroom waterproofing project is a problem that many people are more concerned about, and they are worried that the waterproofing is not up to standard. How to judge whether the waterproofing is done well in the decoration? Let's take a look.

First of all, what to do is to close the water test, its staring function is to verify whether the waterproof function of the waterproof layer is normal, so that you can judge whether the waterproof is done well. Check whether the waterproofing is done well is mainly verified by doing a closed water test.

Secondly, after the waterproofing construction is completed, the water storage test is carried out. You can block all the drains in the toilet or balcony, build a 200mm high water barrier at the door, and then pour in water about 20mm and 30mm deep. It should be noted that the water storage time should not be less than 24 hours, and the ground should be checked for leakage.

Finally, if water leakage is found, the water storage test should be stopped immediately, the waterproof layer should be re-improved, and the water storage test should be carried out after the treatment is qualified. For this reason, in the decoration, the waterproof step is very crucial, and it must be done carefully.

1. Grassroots treatment:

Before waterproof construction, the treatment of the base layer must ensure that it is smooth, firm and dry, without sharp corners, oil and dust.

2. Node protection:

First, the pipeline nodes need to be coated with a flexible pipeline treatment agent to seal the pipeline joints, and then painted with a rigid plugging king to make a 45° slope or arc; The second is the yin and yang angle, and the yin corner of the wall is also made into a 45° slope or arc. After that, it is also necessary to strengthen the additional layer of the node, that is, a layer of waterproof paint should be applied to the node at the dark corner of the pipe or wall root, and 20cm-30cm should be painted at the dark corner of the pipe or wall root. Because most of the water leakage problems in life occur in these inconspicuous node parts, node protection must be done well.

3. Large-area waterproof construction of walls and floors

When painting waterproof coatings on a large area, it should be painted in 2-3 times, and the total thickness depends on the material, generally. The direction of each painting should be consistent, and the direction of the next painting should be perpendicular to the upper road, and the construction of the next road can only be carried out after the first time it is completely done. Brush the wall first and then the floor, and the coating film should be uniform and flat.

For the bathroom, the waterproof height of the wall in the shower area is generally more than 180cm, the dry area should be more than 30cm, and the waterproof height of the wall with water distribution point should be more than 120cm.

4. Closed water experiment:

After the last decoration is waterproofed and completely practical, the closed water experiment is carried out. Plug the floor drain first, the water line at the ground point can not be less than 2 cm, and the water storage should be at least 24 hours (there is also a closed water test for 48 hours, which is more safe) to check whether the waterproof is qualified, and you can observe the water level and the corresponding floor slab and pipeline downstairs to see if there is water leakage. If there is a leak, it needs to be redone, and you must not be negligent.

5. The second closed water experiment:

After passing the closed water test, check the waterproof height, coating thickness, whether it is flat, etc., and then make a cement mortar protective layer with a thickness of 2-3cm to protect the waterproof layer. After the protective layer is completed and completely dried, a second closed water test is carried out according to the standard. The test criteria are the same as those of the first closed water experiment.

6. Acceptance: After the second closed water test is passed, you can sign to confirm the acceptance of decoration waterproofing.

There are synthetic polymer waterproofing membranes, which have excellent elasticity and tensile strength, aging resistance, and adapt to cold construction. There are also polymer modified asphalt waterproofing membranes, which are of good quality, convenient for construction, and relatively low.

The types of waterproof materials can be as follows: flexible mortar, rigid mortar, polyurethane, membrane, acrylic waterproof coating, waterproof membrane. These waterproof materials are relatively good.

There are the following materials: waterproof membrane, polymer polymer waterproof material, cement mortar waterproof material, acrylic, flexible mortar, hard mortar, polyurethane, membrane, acrylic and other waterproof coatings.

You can choose asphalt, you can also choose rubber and cement, as well as metal, plastic, waterproof materials are also very varied, according to the ** and the nature of the screening.

The quality of Hengshui construction affects the quality of life, what are the types of waterproof materials to choose from? There are many varieties of waterproof paper materials, there are indoor waterproof, there are outdoor waterproof, these things, the quality of waterproof is very good, just choose the indoor failure can be.

When doing waterproofing, you must pay attention to the details, and don't bring unnecessary trouble to yourself. And when doing waterproofing, we must find professionals to help us, because those professionals know more than us, and when doing waterproofing, we must pay attention to the temperature problem, and do not let the water freeze. But I think the most important thing is to pay attention to safety when doing waterproofing.

It is necessary to choose some paints with good waterproof performance and apply them to the wall in order to do a good job of waterproofing in the decoration.

You first have to do a good job of moisture-proof work in the place where the floor is built, and use some moisture-proof parts and the like to lay it as a whole.

Do a closed water test, that is, it is waterproof on the indoor ground, and the water does not decrease for 24 hours.
