What are the precautions for roof waterproofing?

The precautions for roof waterproofing are as follows:

1.It is forbidden to carry out construction under 5 or in the case of rain;

2.If the construction is in a particularly humid and ventilated environment, ventilation equipment should be used to speed up the film formation of the waterproof coating, so as not to affect the quality of the waterproof layer;

3.Do not mix the dried mortar with water before use;

4.The node treatment is carried out according to the requirements of the relevant specifications, and it is recommended to add a layer of glass fiber mesh;

5.Within 24 hours after the slurry is applied, it is necessary to prevent people from walking and not wearing high heels or spikes into the waterproof layer area;

6.Before the completed waterproof layer is not a protective layer, there shall be no iron, steel nails, steel bars, scaffolding and other angular heavy objects to be constructed or stacked on the waterproof layer, so as not to damage the waterproof layer;

7.After the waterproof layer is completely dry, other covering layers can be made;

8.Take protective measures, such as wearing gloves.

The waterproofing of the old face of the house is a big project, and all aspects must be taken into account. Not only in the selection of waterproof materials need to be paid attention to, but also in the construction process to be strictly controlled. Let's introduce to you what are the precautions for roof waterproofing?

1. If the construction is in a particularly humid and unventilated environment, in order to ensure the construction quality of the waterproof layer, the doors and windows should be opened or the ventilation equipment should be used to speed up the film formation of the waterproof coating.

2. Try to avoid mixing dry mortar with water and using it in roof waterproofing construction.

3. It is forbidden for people to wear high heels or spikes to walk in the waterproof layer area, within 24 hours after the slurry is applied.

4. Wait until the roof waterproof layer is completely dry and solidified, and then make other covering layers.

5. The yin and yang corners of the base layer of all waterproof construction sites should be chamfered with r=5cm, and they should be neat and smooth.

6. Before paving the membrane, the waterproof screed layer must be cleaned and dried.

7. During the construction of the roof waterproof layer, it is necessary to pay attention to the nodes, which wax to lift the additional layer, and the parts where the roof drainage is more concentrated.

The above is the need to pay attention to the matters in the roof waterproofing construction, the roof waterproofing project can not be sloppy, I hope that you will pay attention to this project.

In real life, many people want to decorate the house themselves after buying it, and the waterproofing of the house is a very important part, which requires certain professional knowledge. So how do you do roof waterproofing? What should I pay attention to when doing roof waterproofing?

How to do roof waterproofing?

1. First of all, we must do a good job of roof cleaning and leveling. Clean up the impurities and dust on the roof, and then level the roof with asphalt mortar. After the base layer is dried, the base treatment agent is evenly applied to enhance the adhesion between the waterproof membrane and the base layer.

Gutters, settlement joints and other weak parts can be paved with waterproof membranes to do a good job of additional layer treatment.

2. When paving the waterproof membrane in a large area, use the spray gun to heat the place where the membrane and the ground meet, and quickly roll the membrane forward. The lap joints on the short side of the adjacent waterproofing membrane need to be staggered by at least 500mm, and the upper and lower layers of waterproofing membrane should be staggered by one-third of the width.

3. After the roof waterproofing is done, we also need to pave a protective layer. We evenly pour asphalt glue on top of the waterproofing membrane, and the thickness of asphalt glue is about 2-4mm. Then sprinkle the adzuki stone and compact it.

The protective layer should completely cover the waterproof layer. If cement mortar is used as a protective layer, you also need to set up an isolation layer.

4. After the construction of the protective layer is completed, the closed water test should be carried out. We plug the drain of the roof, etc., and then store water on the roof, paying attention to the depth of the roof water storage should not be too shallow, and its depth should not be less than 2cm. The water storage time is usually 24 hours, and during the water storage period, we need to check whether there is any leakage problem on the roof and whether the water level has dropped significantly.

If not, it means that the waterproof is qualified.

What should I pay attention to when doing roof waterproofing?

Roof key mold closure and waterproofing is an important measure to ensure the safety of the house and prevent water leakage. The following are the precautions for roof waterproofing:

1. Before the construction of waterproof leakage, the roof must be dry, because the moisture of the roof will not evaporate, and the new waterproof layer will be jacked up, and the waterproof effect will fail immediately. Therefore, construction is not suitable in rainy days, and construction can only be carried out after the sun dries the moisture.

2. Choose regular waterproof coatings, different waterproof coatings have different effects, and we should choose better quality and regular waterproof coatings.

3. After the repair is completed, the waterproof test must be done, and the water storage time must be at least 24 hours, or continuous water spraying for two hours.

4. The waterproof layer should not have cracks, peeling, bulging, uneven thickness or accumulation, exposed tires and wrinkled skin.

5. After the irrigation test is completed and there is no leakage, the insulation layer and waterproof protective layer need to be restored.

To sum up, it is necessary to choose a regular waterproof coating in the process of roof waterproofing construction, and at the same time, it is necessary to strictly implement the construction process standards to ensure that the waterproof layer is of reliable quality and has a long service life.

If the waterproofing project of the house is not done properly, it is easy to leak. What are the precautions for roof waterproofing construction? This site will take you to find out.

1. Robustness requirements.

Slip disturbance because it needs to bear the load brought by wind and rain, but also to transmit the construction load, so it must have sufficient strength and hardness, for the engineering design requirements to use 1:3 cement mortar to make a leveling layer, the construction should be strictly controlled water-cement ratio, moderate control of consistency, water content, etc.

2. Flatness requirements.

For the flatness of the flat layer, it is necessary to use a ruler of 2m to detect, and the plane gap shall not exceed 3mm, and at the same time, it is necessary to ensure that the surface layer is flat and the thickness is consistent, so as to prevent the roof from being waterlogged and remove leakage, so it is best not to bury the pipe in the flat layer.

3. Dryness requirements.

Generally speaking, the moisture content of the base can not exceed 6%, if it does not meet the requirements, it has a great impact on the later construction, the light one plays an isolation role, destroys the bond, and the heavy one causes hollow drum cracking, destroys the waterproof effect, so to ensure the waterproof effect for the branches, the moisture content of the base must be effectively controlled.

4. Cleanliness requirements.

The base must be kept clean and tidy, after cleaning, the dust left in the gaps and corners should be blown clean with compressed air, and the grease pollution, welding stains, brushes, rust spots should be washed and sanded.

In the process of construction, there are many places where you need to master the decoration skills, and about the decoration of the roof, we must first do a good jobWaterproofing of roofsBut what are the requirements for roof waterproofing, as well as the construction of roof waterproofing, what are the precautions, etc., I hope that we will introduce it to you later, and we can help you with the stuffy waterproofing of the roof.

1. What are the requirements for roof waterproofing?

1. At the beginning of the roof waterproofing and bending work, the construction unit should organize relevant technical personnel, who need to review the roof engineering drawings, master the details of the construction drawings and the relevant technical requirements, and can prepare the construction plan or technical measures of the roof project according to the actual situation of the project, so as to avoid leaving defects after construction and will not cause rework.

2. And for the waterproofing of the roof, the base layer needs to be cleaned, and the dust and debris on the surface of the base should be cleaned up before construction, and then modified by hot melt method, and the asphalt membrane should be modified by the waterproof layer before the construction of the water drop, pipe root and yin and yang angles.

3. And when carrying out roof waterproofing treatment, we should choose more suitable and qualified waterproof materials, the quality of waterproof materials must meet the provisions of relevant standards, and can pass the inspection and certification of the quality inspection department, and the appearance of the membrane waterproof layer should be smooth, straight, and there should be no twists and wrinkles.

4. Then when paving the membrane, first of all, the thickness of the membrane must meet the requirements, cut the waterproof membrane into the corresponding size, heat the junction of the base layer and the membrane with a flame spray gun, and take advantage of the material surface of the membrane, when it is just melted, the membrane will be rolled forward and pasted, and the membrane connected to the paving plane and the façade should be carried out downward and upward.

5. The design of the protective layer should comply with the regulations, the isolation layer should be set between the rigid protective layer and the waterproof layer, the setting of the separation joint on the surface of the rigid protective layer should meet the national standards and design requirements, and the protective layer of the block should be paved smoothly, evenly and tightly, and the separation joint should also be left correctly.

6. Hot melt edge sealing, use a spray gun to heat the lap joint of the coil material to make it firmly bonded, and then apply the waterproof coating for the first time. Before waterproof construction, it is necessary to ensure that the ground is clean and dry, the waterproof coating should be fully coated to ensure that there is no omission, and the combination with the base layer should be firm, no cracks and bubbles, etc., and the thickness of the waterproof coating should meet the requirements of the product regulations.

Second, the precautions for roof waterproofing.

1. First of all, about the waterproofing of this roof, how to deal with it correctly, we should pay attention to the fact that waterproof work and insulation construction can not be carried out in rainy weather, and the quality of the waterproof layer of the membrane must meet the requirements, and the degree of dryness must reach a certain standard.

2. Moreover, in the process of waterproofing treatment, because there are gutters and membrane lap places at the corners of the roof, as well as nodes such as water drops, they should be paved firmly, and they should also meet the technical specifications of roof waterproofing engineering.

3. In addition, we should fully exhaust the air between the base layer and the membrane when the waterproof membrane is paved, and pay attention to avoid excessive tension and wrinkles. And for the waterproof membrane paving should be straight, and ensure that it should be constructed in strict accordance with the elastic marking line of the base layer, and the insulation layer laid must protect the waterproof layer.

1. The hole filling work of the roof pipe should be completed before the roof waterproof layer, including the hole filling of the layer pipe. And by a special person is responsible, not by the plumber to fill the hole, to ensure the quality of repair.

Chisel the loose pumice stone on the reserved four walls, remove the garbage, and the bottom mold must be firmly supported to ensure that there is no slurry leakage and no falling.

2. After sprinkling water and wetting in advance, pour 20 1:2 cement slurry grouting, pour C20 plus micro-expansion agent fine stone concrete, and require pouring compact.

3. The next day, caulking with waterproof ointment on its surface, and then leveling the roof with 1:2 cement mortar, and making "steamed bread" around the pipeline, and filling the sealing material between the "steamed bread" and the pipeline and then doing waterproof treatment.
