How to get the roof renovated?How to waterproof the roof?

First, the base requirements.

The base surface is cleaned, the moisture content is not more than 9%, it is smooth and compact, and the end of each node is neat and complete, which meets the requirements.

Second, the first waterproof layer.

1) Lay a flexible waterproof layer, choose paint or membrane. The construction conditions require that the moisture content of the base surface is not more than 9%, so it is suitable for construction in the summer after the hot weather and 5 consecutive sunny days. After completion, water storage experiments should be carried out;

2), such as paint waterproofing, take "one cloth and two coatings" as an example: after cleaning the base layer, brush the paint again, dry the film, lay a layer of fiberglass cloth carcass reinforcement material, and brush a layer of paint on the flattened surface to fix, and carry out the next coating construction after drying. The total thickness of the waterproof coating film should be more than 3 mm;

3) If you do the construction of waterproof membrane, after cleaning the base layer, brush the adhesive glue on the reverse side of the membrane and the base layer, paste and roll according to the elastic datum line from far and near, and finally do the seam closing inspection treatment.

3. The second waterproof layer.

The laying of the rigid waterproof layer should be carried out about two days after the completion of the first flexible waterproof layer, mainly with high-grade fatty acid mortar waterproofing agent, cement, sand, fine stone aggregate, fiber as the basic material, the thickness of the waterproof layer should be 20-30 mm;

1) Install the lattice wood strip according to the requirements of the specification, and the lattice is set to 4000 mm and 4000 mm. Then sprinkle water to moisten the base surface, but there must be no standing water;

2), according to the order from far to near, first high and then low, the prepared mortar or fine stone concrete is constructed one by one, and the same grid is completed at one time, smoothed and compacted;

3) After the initial setting, take out the lattice wood strips, calender and trim the lattice seams;

4) The flexible sealing material is used to embed and fill the lattice seam to treat the surface closing. After the construction is completed, pay attention to sprinkling and curing;

5) If there is roof planting soil, it should be covered with planting soil in the shortest possible time.

Step 1: The general construction process of the roof.

Acceptance of the screed, cleaning of the base layer, preparation of cement binder, additional layer, base construction, protective layer maintenance. Before the membrane is laid and bonded, the roofing waterproofing membrane is pre-spread and aligned, and then the two ends of the roofing waterproofing membrane are folded and rolled up, the prepared cement adhesive is poured into the base layer, and the scraper is evenly scraped, and then the roofing waterproofing membrane is pushed forward, and the air left inside the roofing waterproofing membrane is removed with a scraper in time to scrape out the excess binder. The adhesion rate of the roofing waterproofing membrane to the screed is 85%.

Step 2: Indirect seam of the coil.

Construction of waterproof joints on the roof: the vapor insulation layer, the waterproof layer and the additional layer are all bonded with cement adhesive by lap joint method, with a width of 10cm. The seams of the additional layer and the seams of the waterproof layer are staggered by more than 5cm.

The lap width of the roof waterproofing membrane is 8-10cm on the long side, 10-15cm on the short side, the adjacent short side joints should be staggered by more than 100cm, and the angle between the wall and the ground is more than 30cm.

How to do roof waterproofing Step 3: Waterproof protective layer.

After the membrane is paved and glued, it is necessary to do 1: the protective layer of cement mortar with a thickness of 2cm is divided into two times, and the second layer of stubble must be staggered by more than 20cm, and the protective layer is required to be smooth and sprinkled for maintenance.

Some owners who buy a penthouse will worry that the waterproofing of the penthouse is not done well and there will be water leakage, because they want to do the waterproofing again to prevent it. So how to do waterproofing for top floor decoration? Next, I will briefly introduce it to you.

1. Under normal circumstances, the developer will do a good job of waterproofing on the roof, and the owner can do a water storage test on the roof when receiving the house, or check whether there is a leakage on the roof after the rain. If there is a water leak, we can ask the developer to repair it; If the owner is not at ease and wants to do the waterproofing again, then you can cooperate with other top floor owners to negotiate with the property to brush a layer of special waterproof paint or other waterproof materials on the floor slab, and add a layer of cement mortar protective layer. Roof waterproofing needs to be done as a whole, and it is useless to do only partial waterproofing.

2. When decorating the top floor, it is necessary to do a good job of waterproofing the kitchen and bathroom balcony, when we do the waterproofing of the kitchen and bathroom balcony, the floor drain part, the connecting part of the water pipe and the wall are relatively easy to leak, and the treatment should be strengthened; The waterproof coating is generally applied 2-3 times, and the thickness of the brush is to be cross-shaped before and after the two coatings. The waterproof height of the shower wall of the bathroom is 180cm; The painting height of kitchen and balcony walls is generally 30cm; The joints between the windows and walls of the balcony should be sealed.

3. According to the experts of Qeeka Home, because of the location advantage of the top-floor residence, outdoor restaurants, leisure areas, etc. can be designed, and we must do a good job in waterproof and thermal insulation measures in the decoration design. After we do a good job of waterproofing, don't forget to do a 24-hour closed water test to make sure that there is no problem with waterproofing before proceeding to the next process. In addition to waterproofing for cooking, don't forget to do thermal insulation measures in the penthouse house, such as installing a suspended ceiling, you can put an insulation board between the ceiling and the roof.

Summary: About how to do waterproofing for the decoration of the top floor, I will briefly introduce it to you here. I hope that after reading this article, I can provide you with reference and help when decorating the top floor.

The waterproofing measures on the top floor of the house are particularly important, so what are the steps to waterproof the roof?

First, what are the steps of the roof waterproofing?

1. Base treatment, clean up the dust and debris on the surface of the base layer before operation, and then use the hot melt method to paste the coil to the downspout, pipe root, yin and yang corners and other delicate parts to make an additional layer.

2. Pave the coil to ensure that the thickness of the material is up to standard, and then cut it to the required size, and then the flame spray gun heats the place where the base layer and the coil overlap, and rolls it forward when it has just melted.

3. Hot melt edge sealing, take a spray gun to spray heat at the place where the coil is connected, ensure that it is pasted firmly, and then paint a waterproof coating, before waterproof construction, ensure that the base is dry and tidy, and the paint should be full and firm when brushing, without omission, cracks and bubbles, etc., and the thickness should also meet the requirements.

4. After the first waterproof coating penetrates, you can do the second brushing, otherwise it will affect the waterproof effect.

5. Paving the protective layer, after the waterproof construction is completed, the protective layer on the outer layer can avoid the damage of the waterproof layer during construction, pay attention to the protective layer must be completely covered, no omission, so as to ensure that the base layer is firmly combined, and there are no bubbles and falling off the situation.

6. Closed water test, during the experiment, the height of the water should not be less than two centimeters, and it should last for more than 24 hours to ensure that there is no leakage before reaching the standard.

2. What are the points to pay attention to in roof waterproof construction?

1. If it is rainy weather, it is forbidden to do waterproof and thermal insulation construction.

2. The quality of the waterproof layer of the membrane used should meet the requirements to ensure that the dryness meets the standard.

3. The exhaust between the muscle layer and the coil should be done well to prevent too tight stretching or too many folds.

Summary: The above is the method and steps of waterproofing the roof, we can see from the above article that we must be careful and cautious in accordance with the steps when the actual construction, so as to ensure the smooth operation of the project and avoid many problems, I hope to help you.

The waterproofing of the roof is also a very important step in the decoration construction, so how to do the steps of waterproofing the roof?

The roof needs to be treated first to ensure the flatness of the roof. First of all, it is necessary to do leveling, clean the surface layer of the bridge to ensure that there is no dust and impurities, and the cement adhesive needs to be configured and put aside. If the roof is uneven, first carry out slope finding treatment and install the expansion joints.

After leveling with cement, it is necessary to calender to ensure the flatness before the construction of waterproof materials can be carried out. Then the waterproofing membrane is prepared, the surface of the roof is spread out to level and vertically distribute the source, and then the membrane is folded diagonally in half, the prepared cement mortar is poured on the surface of the roof, and the membrane is spread forward after scraping evenly. While laying, the air inside should be exhausted and the excess cement binder should be squeezed out.

After the waterproofing membrane is paved, a protective layer of Zen road mortar is made on the surface, with a thickness of about millimeters, which can be divided into two constructions, and finally sprinkled for maintenance.

When it comes to the rainy season, many people have such troubles, if the waterproofing measures on the roof are not in place, it is easy to have the problem of water seepage. We can choose to do waterproofing measures on the roof when the weather is fine, how to make the roof waterproof to achieve the effect? What problems need to be paid attention to in the process of waterproofing?

1. How to make the roof waterproof.

1. When doing roof waterproofing, you first need to choose a good waterproof material, and you must ensure quality and safety.

2. Next, the roof needs to be treated, such as leveling the roof surface and cleaning the surface, so that there is no dust, no impurities, etc.

3. Carry out slope finding treatment according to the requirements of the design, and at the same time, make the roof surface more solid, and use cement mortar to condense the surface of the waterproof layer, so as to be ready for laying the waterproof membrane.

4. Lay the waterproof membrane or brush the waterproof material, if you choose the waterproof membrane, you need to lay it on the surface, and then do the leveling vertical. Next, you can pour the adjusted cement mortar onto the roof surface and scrape it evenly with a scraper. The waterproofing membrane is then spread forward, while the air in the membrane is squeezed out with a scraper, as well as the excess adhesive.

5. After the waterproof membrane is laid, another cement mortar should be made on the surface as a protective layer, and the thickness should generally reach about two centimeters, which can be divided into two constructions. Next, do the maintenance, you need to sprinkle water, and then it will be in place.

2. Precautions for roof waterproof construction.

1. When we are carrying out construction, it is best to choose a one-time construction, and at the same time, we must pay attention to the selection of products, and choose excellent quality to effectively avoid the trouble of water leakage in the later stage.

2. After the waterproof construction is completed, it is necessary to do a closed water test, mainly to observe whether there is water leakage on the roof, if there is no water leakage for a few days, it means that the waterproof construction has been successful.

I concluded: Now more people have to do the roof waterproofing project, so whether it is from the selection of materials in the early stage to the later construction, it is necessary to strictly follow the requirements and specifications, so as to ensure that the waterproofing is in place at one time and solve the trouble of water leakage once and for all.
