How to improve the waterproof construction quality of polypropylene cloth?

The construction of polypropylene waterproofing must pay attention to details, handle each important part well, and never allow cutting corners.

The waterproof construction process of polyethylene polypropylene cloth is as follows:

Acceptance and cleaning of the base layer (screed) Preparation of adhesive (preparation) Treatment of complex parts (yin and yang corners, mouths, outlets, pipe holes, etc.) Additional layer Construction of waterproof layer Waterproof layer inspection After the construction acceptance of the protective layer.

Polyethylene polypropylene waterproofing membrane solid blue building waterproof construction operation procedures:

1. The base layer (leveling layer) of the waterproof membrane must be cleaned and sprayed to ensure that the base layer is wet. (Note: The roofing waterproof screed shall comply with GB50207-2002 "Roofing Engineering Quality Acceptance Code", and the underground waterproof screed shall comply with GB50208-2002 "Underground Waterproof Engineering Quality Acceptance Code").

2. The cement slurry binder is prepared with polyvinyl alcohol glue containing 5 15 cement, and the mixing must be uniform, without precipitation and clot. It can be used without isolation.

3. Before the construction of the main waterproof layer of the roof, the sealing treatment and additional layer bonding should be carried out on the detailed nodes with concentrated drainage and complex structure.

4. The sealing material is made of polyether polyurethane. If other sealing materials are used, they should be free of mineral oil, petroleum jelly and other chemicals that can affect the performance of polyethylene.

5. An additional layer should be added to the corner; The yin and yang angles are r=20mm arcs.

6. The waterproof membrane should be covered by the full laying method. The adhesive coating should be uniform on the base layer, not showing the bottom and not accumulating; Immediately after the adhesive is applied, the coil should be laid. Prevent it from taking too long to affect the quality of the bond.

7. The waterproof membrane should not be wrinkled, and the coil should not be stretched. Air and excess adhesive underneath the coil are removed by the edges to ensure the bond between the coil and the base and coil layers.

8. The lap width of the laid waterproof membrane shall not be less than 100mm.

9. The upper and lower layers and the adjacent two web joints should be staggered by one-third of the width.

The process of polypropylene cloth waterproofing material is very complicated, because some adhesive should be used in the construction, and the base layer needs to be cleaned. When applying, make sure the base is wet. Polypropylene cloth waterproofing material is a very high-grade waterproof membrane.

This waterproofing membrane is also relatively expensive, so it shouldn't be pulled too hard. When installing this waterproofing membrane, the first thing to do is to determine the size, and the adhesive must be used evenly, otherwise unevenness will occur.

First: the construction temperature of polypropylene cloth waterproof is room temperature, and cement glue can be directly used to connect the required composite membrane with other bases, this construction process is more convenient and fast, can effectively reduce the degree of labor, and the pollution of the environment will be greatly reduced, and the wage efficiency will also increase.

Second: polypropylene cloth waterproofing uses the construction technology of strip sticking, so that the composite membrane laid will not have much impact even if it is deformed, in some relatively small structures, its waterproof method is to use cement glue for bonding, which can greatly improve its connection degree.

Third: the construction of the waterproof layer of polypropylene cloth is very simple, it will not change due to the change of seasons, and there is no pollution to the environment, and the material also has good stability.

Fourth: when using polypropylene cloth for waterproofing, special production processes need to be used in some special parts, and special attention should be paid to the closing position of the composite membrane, if it is not handled properly, it is likely to cause opening, falling off and so on.

Fifth: The construction of polypropylene cloth waterproofing at the yin and yang corners must be careful, its additional layer must be strengthened, and many times of construction and inspection are required.

Pro, the specific construction steps of the polypropylene cloth waterproof membrane are as follows: 1. The base must be cleaned and sprayed with waterproof membrane to ensure that the base layer is wet. 2. The cement slurry adhesive must be made of polyvinyl alcohol glue containing 5%-15% cement, and it needs to be uniform when making.

3. Before the waterproof construction of the house, the sealing operation should be carried out in the position with a lot of drainage and complex structure. 4. The sealing material is made of polyether polyurethane. If other kinds of materials are used, the material must not contain mineral oil, petroleum jelly, etc., which will affect the properties of polyethylene.

5. The coil should be laid comprehensively, the coating of the adhesive should be uniform, and the coil should be laid immediately after the adhesive is applied. 6. After the waterproof membrane is laid, the waterproof membrane shall not be wrinkled, the coil shall not be stretched, and the coil, base layer and coil layer shall be bonded completely.

Summary. Hello, dear, use polypropylene cloth to do waterproofing, hot precautionary measures: 1. During the construction process, if the polypropylene cloth is scratched and other ruptures, it should be repaired in time, and tools should be placed during construction to avoid damaging the waterproof layer.

2. After the waterproofing is done, you can't walk immediately, and the solidification time should reach at least 48 hours.

3. The waterproof construction temperature of polypropylene cloth should be between 5 °C and 30 °C, and the waterproof material should not be rained within 24 hours after it is paved. If there is rain during the solidification period, take protective measures. 4. If you do waterproof construction in winter and the temperature is below 5 °C, you should use antifreeze special glue and waterproof cement mortar to freeze and crack.

And after the construction is completed, the ground should be covered with anti-freezing measures such as film or straw curtains.

5. The polypropylene cloth should be used with some adhesives before waterproofing, and the ground base should be cleaned before waterproofing, and the base layer should be guaranteed to be moist. And when using this material, it is also necessary to avoid contact with grease substances, so as not to affect its waterproof effect.

6. When using polypropylene cloth for waterproofing, the size of the waterproof material should be measured first, and the adhesive should be evenly applied, otherwise there will be unevenness during waterproofing.

Polypropylene cloth waterproofing is one of the more common waterproof membranes in the decoration now, because it can be directly constructed on the wall and the ground, and is very popular, but this waterproof membrane can only be used for indoor construction, and can only be mixed with wall sand and ash, and it is necessary to configure some adhesives and treat the base layer during construction, which is more complex than other waterproof membranes, so what are the steps of polypropylene cloth waterproofing practices? Let's take a look with Qeeka Home experts.

1. What are the steps of polypropylene cloth waterproofing?

Polypropylene cloth waterproof practice steps: the base layer is accepted and the tung is cleaned and sprinkled with water to moisten, the adhesive is prepared and stirred evenly, the complex parts such as the yin and yang corners are treated, and the sealing treatment and additional layer are pasted, the adhesive is brushed and the polypropylene cloth is covered with waterproofing, the qualification of the waterproof layer is checked, and the protective layer is maintained.

Second, what problems should be paid attention to in the waterproof construction of polypropylene cloth.

1. Pay attention to the construction temperature.

Polypropylene cloth waterproofing membrane should be constructed in a normal temperature environment, and the temperature that is too hot or too cold is not suitable for construction, which will affect the construction quality and lead to poor waterproof effect.

2. Pay attention to the treatment of special parts.

Polypropylene cloth waterproof in the deformation joints, pipes, yin and yang field hall corner and other special parts of the construction, not only to use special construction technology, but also to clean these areas to ensure that the pipe, the seam is unobstructed, if the treatment is improper, it is very likely to cause the opening of the mouth, falling off and other phenomena, the yin and yang corners to carry out additional layer strengthening treatment, multiple construction, inspection, etc.

3. Do a good job of protective measures.

The polypropylene cloth waterproof membrane should be protected in time after construction, mainly to prevent damage to the waterproof membrane caused by machinery and tools, later construction operations, etc., which will affect the construction effect of polypropylene cloth waterproofing.

Polypropylene cloth waterproofing is a kind of waterproof membrane, which is generally directly constructed on the ground and can be directly laid on the wall. This material generally cannot be used outdoors, only indoors, and can only be mixed with wall sand. Polypropylene cloth waterproofing needs to find the base layer when carrying out construction, and then it needs to be equipped with some adhesives, and the processing part is more complicated, because it can only be used indoors.

Do you know what are the advantages and disadvantages of polypropylene cloth waterproof? Now let's take a look at the advantages and disadvantages of polypropylene cloth waterproofing and the process flow.

1. Advantages and disadvantages

The advantage is that the ground can be bonded well with the wall sand and plaster during construction, and the disadvantage is that it is not conducive to outdoor use.

Second, the construction operation procedures

Acceptance and cleaning of the base layer (screed) Preparation of adhesive (preparation with use) Treatment of complex parts (yin and yang corners, cornices, downspouts, pipe holes, etc.) Additional layer Construction of waterproof layer Waterproof layer inspection and sliding inspection After the construction and acceptance of the protective layer.

1. The base layer (leveling layer) of the waterproof membrane must be cleaned and sprinkled with water to ensure that the base layer is wet. (Note: The roof waterproof screed layer shall comply with the provisions of GB50207-2002 "Roofing Engineering Quality Acceptance Code", and the underground waterproof screed layer shall comply with the provisions of GB50208-2002 "Underground Waterproof Engineering Quality Acceptance Code").

2. Use polyvinyl alcohol glue containing 5% and 15% cement weight to prepare cement slurry binder, and the stirring must be uniform, no precipitation, no clot. It can be used without segregation.

3. Before the construction of the main waterproof layer of the mambura roof, the detailed nodes with concentrated drainage and complex structure should be sealed and pasted with additional layers.

4. The sealing material is polyether polyurethane. If other sealing materials are selected, they should be free of mineral oil, petroleum jelly and other chemicals that affect the performance of polyethylene.

5. Additional layers should be added at the corners; The yin and yang angles are made into an arc shape of r = 20mm.

6. The waterproof membrane should be paved with full paving, and the adhesive should be evenly brushed on the base surface, without exposing the bottom and not accumulating; After the adhesive is applied, the coil should be laid. Prevent too long a time from affecting the quality of the bond.

7. The waterproof membrane shall not be wrinkled and broken, and the membrane shall not be stretched vigorously. The air and excess adhesive under the coil are eliminated while laying the welt to ensure that the coil is bonded to the base layer and between the layers of the coil.

8. The lap width of the paving waterproof membrane shall not be less than 100mm.

9. The joints of the upper and lower layers and the adjacent two coils should be staggered by one-third of the width.

The process of polypropylene cloth waterproof material is very complicated, because it needs to be equipped with some adhesives when carrying out construction, and it is also necessary to clean the base layer of the room. When carrying out construction, it is necessary to ensure that the base layer is wet. Polypropylene cloth waterproof material is a very high-grade waterproof membrane, this waterproof membrane is also relatively expensive, so it can not be stretched too hard.
