How to make a good roof waterproofing effect? What s the best way to do it?

The use of high-quality waterproofing materials, strict construction, construction on sunny days, and attention to the slope of drainage are good for the waterproofing effect of the roof.

If the roof waterproofing is not in place, there will be water leakage, which will affect people's normal life, so when decorating the house, the roof waterproofing should be in place, and it is necessary to use high-quality waterproof materials at this time.

1. Strict construction

Roof waterproofing wants to have a good effect, must be strict construction, not only to buy high-quality waterproof materials, but also to carefully check the construction drawings of the roof, master its detailed structure, pay attention to the roof drainage slope, its slope can not be less than 2%, otherwise the water will stay on the roof for a long time, will make the roof leak, will affect the effect of waterproofing. Before the start of construction, the necessary treatment should be done on the wall, not only to clean the garbage on the surface, but also to remove the oil and other impurities on the top of the layer, so as to avoid affecting the waterproof effect due to their presence.

2. Construction on sunny days

When doing roof waterproofing, it should be constructed on a sunny day, and the ambient temperature should be above 5 degrees, and it must not be constructed on a rainy day, because on a rainy day, the external environment is relatively humid, and the timing waterproof material can not form a film, its waterproof effect will be greatly reduced, and the quality of waterproof construction will also be greatly affected. Other coatings can be applied only after the waterproof materials such as Qingtian construction are dry, so that there will be a better waterproof effect.

3. Pay attention to details

Pay attention to the details of the roof waterproofing, in order to have a good waterproof effect, the construction process of the mortar has been dry in the case can not add water to continue to use, and in the treatment of the node must lay a layer of fiberglass mesh, so as to avoid the node part of the leakage, in addition to the construction can not be completed within 24 hours can not walk on it, let alone wear high heels into the waterproof layer area, otherwise the waterproof materials will be damaged, will also affect their waterproof effect.

1. Make the most basic preparations first. Then clean the base layer to ensure that there is no dust and construction debris on the base layer before construction.

2. Then brush the base treatment agent, if the polymer modified asphalt membrane is used for construction, we must use it in accordance with the regulations, after the base treatment agent is mixed evenly, it is smeared on the surface of the base with a long roller brush, and the coil can be paved after 4 hours under normal circumstances.

3. The additional layer can be completed with modified asphalt membrane hot melt, and the additional layer is made on the parapet wall, water drop, pipe root, yin and yang corner, etc., and the area of the additional layer should be in line with the provisions of the design.

4. Paste the coil, hot melt edge sealing, and heat the overlapping parts of the coil with a hot melt gun. Do experiments on waterproof water storage.

5. Check the records, this work is usually accepted by professional quality inspectors and recorded. The maintenance of the waterproof layer protects the finished product.

You can use special waterproof materials, do a good job in the configuration of cement and materials, and pay attention to specific practices. Prepare for the work, adopt the design of thermal insulation, or the design of rigid and flexible, or use the drum design, pay attention to the proportion of materials and cement, pay attention to the slope of the roof, and the combination of waterproof steps.

Roof waterproofing is also a very important process. The quality of waterproofing works directly affects the service life of the building and our lives. After the waterproof material enters the site, the factory inspection report and factory certificate should be attached, and the production date, batch number, specification and name should be indicated.

The construction unit shall take samples for re-inspection as required. Sampling and re-inspection strictly implement the witness sampling and sample delivery system. If the call is witnessed by the representative of the construction unit or the personnel of the supervision unit, the construction personnel shall take samples on site and send them to the laboratory for testing.

After passing the re-inspection, the re-inspection test report and the qualified unilateral party can be used for waterproof projects.

It is strictly forbidden to use unqualified waterproof materials in the project. Once non-conforming materials are found, the construction site should be evacuated immediately. Before the construction of the roofing project, the construction unit shall organize the technical management personnel to jointly review the roofing engineering drawings, master the detailed structure and related technical requirements in the construction drawings, and prepare the roofing engineering construction plan or technical measures according to the actual situation of the project.

This avoids defects left behind after construction and rework. At the same time, according to the construction organization, the project construction should be carried out in a planned manner to prevent the omission, disorder and reversal of the work from affecting the quality of the project.

Before the roof waterproofing, the ground is leveled with cement mortar, and then the roof is waterproofed so that the roof does not leak after thinning. After the ground is cleaned, apply polyurethane waterproof coating 2-3 times, the waterproof effect is better, and it is not easy to leak. The base treatment agent is diluted by adding a neoprene bitumen binder to the gasoline.

Cut the modified asphalt waterproofing membrane into a suitable size for the slag trap. When paving, the coil is placed while the base layer is heated with a flame lance and connected to the coil. The membrane should be parallel to the ridge and then laid upwards from the cornice.

The coil overlap with a bidirectional flow gradient should follow the flow direction. The width of the lap between the long side and the end is 80mm, and the end seam is staggered by 50mm. The membrane laid on the plane should be connected with the façade, so that the membrane is close to the yin and yang horns, and should not be pulled too tightly.

Heat the coil seam with a spray gun and then join it firmly. The ends need to be tightly filled with sealing paste.

First of all, after cleaning up the stains and garbage on the roof, lay some waterproof membrane after drying for a period of time, cut according to the area of the roof, and choose the kind that is thicker than the sail royal and will not be dismantled quietly after the wind and sun, and you can also apply several waterproof coatings; When doing roof waterproofing, we must pay attention to cleaning up the garbage on the surface first, and we must weld all aspects of the membrane.

You can use some waterproofing material on the roof first, then do a layer of waterproofing, and then lay some waterproofing products. The problem that needs to be paid attention to is to pay attention to the degree of waterproofing, pay attention to the weather on rainy days, and pay attention to the treatment of every detail, the treatment of every corner of the branches, and the waterproofing of the interior of the house.

It is necessary to use waterproof materials with guaranteed quality, choose to carry out construction on sunny days as much as possible, strictly carry out the construction in accordance with the construction standards, and pay attention to the slope of drainage; You can use the treatment surface to effectively achieve the waterproof effect of the roof, you can also paint the treatment agent of the base layer, or pave some seepage and slip membrane, pay attention to the number of layers and thickness of the membrane, all of which must meet the design requirements.

Summary. Hello dear, it is recommended to use a combination of asphalt membrane + waterproof coating for roof waterproofing, asphalt membrane has thickness and good waterproof performance.

Hello dear, it is recommended to use a combination of asphalt membrane + waterproof coating for roof waterproofing, asphalt membrane has thickness and good waterproof performance.

First of all, we must deal with the base layer of the roof, and keep the surface of the base layer of the construction flat, clean and free of debris, no sharp corners, no grease, no water and cracks. Only by keeping the surface clean can we ensure that the waterproof coating can effectively penetrate into the cement mortar, strengthen the bonding between the waterproof coating and the base layer, and improve the waterproof ability.

Usually the waterproofing of the home roof is the use of liquid coating, this waterproof coating film drying speed is fast, the surface of the coating film is bright after drying, good elasticity, good crack resistance, good water resistance, strong adhesion.

If the subject is a sloping roof, it doesn't matter if you do it or not, because the sloping roof itself is a precautionary measure prepared for waterproofing in the later stage, and the sloping roof also effectively plays a role in heat insulation. and will not damage the structure. The outdoor waterproof developer has done, of course, it is not excluded that there is still a hidden danger of water leakage, if there is a problem within the warranty period, you can directly find the property, it is best to accept the top floor waterproof when receiving the house, confirm the qualification and then decorate.

<> don't need to do it yourself, and the developer is responsible for the quality problems during the waterproof warranty period. After the new house is delivered, it must be accepted and the outdoor waterproof quality can be decorated only after it is qualified. When you decorate, you can consider whether to do indoor insulation (ceiling, gable) according to the quality of the house and the place of residence, and the purpose is to prevent cold in winter and heat in summer.

I don't know if you're talking about a commercial building or a self-built small western-style building, if it's a commercial building, the developer of the waterproof has already done, if it's a self-built house, the top floor must be waterproof, now there is no leakage, there will be leakage in a few years, and then do waterproof treatment is like making up for the sheep.

If it is a sloping roof with roof tiles, the problem is not big, and the main attention is that the 9 positions of the expansion joint are easy to leak. If it is a flat roof, it is best to make it waterproof yourself, if there have been signs of rain leakage before, the roof will be yellowed and blistered, it is recommended to ask the previous homeowner or the relevant housing management station whether it has been repaired If there is no trace of water seepage, you can also ask the housing management station When is the most recent waterproofing, it is generally guaranteed for 3-8 years, and there is information from the housing authority, if it reaches the critical value, it is recommended to do it again It is not much money.

It is necessary to smash off the protective layer for waterproof repair, and now there are many kinds of outdoor waterproofing membranes, such as aluminum foil surface, sand surface, schist surface, etc. The waterproofing membrane on the aluminum foil surface can reflect the sun's rays to the greatest extent, reduce the indoor temperature, and can well delay the life of the waterproof layer

When waterproofing coatings and mortar waterproofing agents are used together, the effect of roof waterproofing will be better.

I think when we make the roof, we need to make the cement on it very thick, because it is not easy to leak, and it can make the house so dry.

First of all, the base layer should be cleaned and the roof should be kept clean; Then apply enough waterproof material to the key parts, and treat the cornice, water drop and other parts.

The method of doing roof waterproofing: apply high-quality waterproof coatings, strict engineering construction, engineering construction on sunny days, and pay attention to the slope of drainage pipes, so that the roof waterproofing effect is very good. The situation of water leakage will occur if the roof waterproof is not in place, which will endanger everyone's normal life, so in the case of decorating the house, the roof waterproof guarantee bit, do a good job at this time to apply high-quality waterproof coatings, in the process of purchasing, you can not choose what three no products cheaply, as far as possible to buy these waterproof coatings that meet the national standards, to pass the quality inspection of the relevant departments, only this waterproof coating has a good moisture-proof practical effect.

Roof waterproofing to be very good, must be strict engineering construction, not only to buy high-quality waterproof coatings, but also need to carefully inquire about the roof engineering drawings, grasp its key point structure, pay attention to the roof drainage pipe slope, its inclination can not be less than 2%, otherwise the water will stay on the roof for a long time, will make the roof seepage, will endanger the actual effect of waterproofing. Before the gradual construction of the project, it is necessary to solve the needs of the wall, not only to clean up the waste on the surface, but also to remove the oil stains and other residues on the top of the layer, so as to prevent the actual effect of moisture-proof due to their appearance.

In the case of roof waterproofing, the project should be constructed on a sunny day, and the working temperature should be above 5 degrees, and the decoration construction must not be done on a rainy day, because of the rainy day, the external environment is relatively wet and cold, and the engine timing waterproof coating can not be coated with film, and its actual effect of moisture-proof will be greatly affected, and the quality of the waterproof project will also suffer from great harm. After the waterproof coating such as the construction of the Optimus Pillar project solidifies, other architectural coatings can be wiped, so that a better moisture-proof actual effect will occur.

The method of selecting waterproof materials: according to the characteristics of various waterproof materials, the ductility regulations of various waterproof materials are clearly proposed. The drain is blocked!

The application of waterproof membrane or waterproof material to carry out moisture-proof, should be selected according to the actual situation and economic capacity, it is best to apply water-soluble new environmental protection materials The current waterproof coating has already been upgraded, the construction method is particularly simple, either open the brush immediately, or immediately paste it on it, and the construction of the project is convenient because the flat roof is in direct contact with the outdoors. In the case of rainy days, precipitation will be stored on the flat roof, which leads to many problems of water leakage on the flat roof.

A good choice is CPC, which is made of nanomolecules. Be sure to consider the local rainfall, choose a more water-resistant one, and also take into account the actual building surface.

It is necessary to judge according to the local situation, and if the rainfall is relatively large, try to choose a stronger waterproof. Be sure to be even when brushing the paint.

The waterproofing of the roof is very crucial, you should choose a better waterproof material, if necessary, try to choose to do double waterproofing, so that it can be better.

1. To deal with the appearance, the roof needs to be leveled with cement mortar before waterproofing, and then the roof is waterproofed, so that there will be no leakage after being thin. After the ground is cleaned, use polyurethane waterproof paint to brush 2-3 times, so that the waterproof effect is better and it is not easy to leak.

2. Brush the base treatment agent, the base treatment agent is diluted by adding neoprene asphalt adhesive to gasoline, be sure to stir evenly, and then evenly apply it on the surface of the base with a large roller brush, and after four hours, you can start to pave the coil.

3. Paving the coil.

1) The number of layers and thickness of the coil should meet the requirements of the design. If you need to lay more, the seams must be staggered. The modified asphalt waterproofing membrane is cut to a suitable size, and the membrane is placed while the membrane is laid during paving, and the base layer is heated with a flame spray gun to connect with the membrane.

2) The coil should be parallel to the ridge, and then paved from the cornice to the top, the two-way flow slope membrane lap should follow the direction of the flowing water, the lap width of the long side and the end is 80, and the end stubble should be staggered by 50.

3. The membrane of the plane paving should be connected with the façade, so that the membrane is close to the yin and yang corners, and the membrane cannot be pulled too tightly.

4. How to do hot-melt edge sealing and roof waterproofing, heat the membrane connection with a spray gun, and then firmly connect it together, and the end needs to be filled tightly with sealing paste.

5. Water storage test, after the membrane waterproof layer is completed, confirm whether the style is required, and then irrigate, the water surface should be about 20 mm higher than the highest part of the roof, and observe after 24 hours, if it will not leak, it is qualified, otherwise it needs to be reworked.
