How to do waterproofing of open air balconies?

The waterproofing layer of the open-air balcony you are talking about is generally made during the construction stage. The practice of three oils and two felts you said is the old way, and the current practice is to make a thick waterproof layer - modified linoleum waterproof layer. If you want to go to people often, you also need to make a hardened layer on top of the waterproof layer.

1. Clean up the base layer; 2. Use cement mortar leveling, put the water at the floor drain according to the slope of 2 100, 3. Lay 1 layer of non-woven fabric immediately after brushing JS waterproof coating, and then brush 1 JS waterproof coating (note: the wall should also be turned up to 300mm); 4. After the waterproof layer is dry, do a 24-hour water maintenance test; 5. AFTER PUTTING OUT THE WATER, DIRECTLY PAVE THE FLOOR TILES ON IT (IT IS BEST TO LEAVE THE SEAM TO PAVE, THE SEAM WIDTH IS 5MM, AND THEN IT IS TREATED WITH STRUCTURAL ADHESIVE).

Many families require open-air balconies, open-air balconies waterproof treatment methods. To buy a waterproof material that is qualified for the material, do not buy a cheap non-conforming material cheaply. Otherwise, waterproofing cannot be guaranteed.

It can be waterproofed again. Then there will be no problems in general. You can't add protection one more time at a time.

The floor leakage of the open-air balcony should be done well, and there should be a certain angle. Otherwise, there is stagnant water, which is difficult to remove. This requires careful attention from experts.

After eradicating the original waterproof layer, leveling the water that was originally left in the insulation layer below, setting up exhaust holes, making an exhaust method, and discharging the water of the insulation layer. After the waterproof layer is over, the slope treatment must be carried out, and the roof part of the water storage should not be formed, and the cement mortar is usually set to find the flat slope, and the slope of the slope is more than 3%. If it is rehabilitated and beautified, the waterproof layer we want to do needs a root waterproof layer, and the root waterproof layer needs the transformed asphalt membrane waterproof layer and polymer membrane waterproof layer.

After the waterproofing is completed, the water sealing test should be carried out to ensure that the water does not leak as the qualification, and the maintenance and tile decoration on the rehabilitation should be carried out.

In the end, when beautifying, beautifying and civil engineering cross operations, do not damage the waterproof layer of the lower part, and repair it in time once damaged. The answer to this question is yes. If the waterproofing is not good, the thunderstorm is easy to be baptized by rain, the wall and ground are easy to be damp and leak, and the wall is dusted off, which will cause serious damage to the roof downstairs and will also affect their economic losses.

So waterproofing in the attic open-air balcony is necessary. The waterproofing implementation project of the attic open-air balcony mainly includes the following aspects.

When waterproofing the open-air balcony, it is necessary to paste a layer of waterproof membrane first, and then lay a waterproof layer and pour cement, so that the waterproof treatment can be done.

First of all, the base layer should be cleaned up, then paved with cement mortar, and finally brushed with JS waterproof coating, and finally after the waterproof layer is penetrated, do a 24-hour water maintenance test. Finally, drain the water, lay floor tiles directly on top, then treat the bottom edge, and finally install glass windows.

First of all, clean the balcony, then make two floor drains, then brush a layer of waterproof paint, try to brush a few more layers, and then spread a layer of tarpaulin, which is very good.

Do some waterproof preparations, lay some waterproof cement and cloth so that you can be well waterproof.

Happy e family friendship reminds you to use the best construction method of three oil and two felt, that is, brush a layer of polyurethane first, then lay a layer of linoleum, brush once polyurethane, then lay linoleum, and finally brush a slightly thicker polyurethane. Linoleum must pay attention to lapping, the interface is facing the running side, and the non-flowing side of the linoleum should be turned up 15-20 cm.

Mainly look at the top surface of what substrate, explain.

The construction method of three oil and two felts is adopted, that is, a layer of polyurethane is brushed first, then a layer of linoleum is laid, then polyurethane is brushed again, linoleum is laid again, and finally a slightly thicker polyurethane is brushed again. Linoleum must pay attention to lapping, the interface is facing the running side, and the non-flowing side of the linoleum should be turned up 15-20 cm.

The ground is clean, free of dust and particles, spray a little water, but there should be no open water.

Then brush the potatoes and plums 2-3 times, such as waterproof materials, disturb the abrasive, wait to dry thoroughly, do a 24-hour closed water test, no leakage, you can do it.

This involves the construction process. 1.Clean the construction site and sprinkle water to make it fully moist but there should be no stagnant water.

2.Wall: The total thickness of the waterproof layer (waterproof mortar + waterproof mortar) is not less than 10 mm, and the height is not less than 1800 mm.

1) Mix "Laoyal" with cement to form a waterproof mortar, and paint it once or twice on the base surface with a total thickness of 2 mm.

2) After 20 minutes, after the waterproof mortar is dry, mix it with "Laoyal" with cement and sand to form a waterproof mortar, and wipe it on the surface of the waterproof plain ash with a thickness of 8 mm.

3) After the waterproof mortar layer is solidified within 24 hours, it is sprinkled with water for curing.

3.Ground: The total thickness of the waterproof layer (waterproof mortar + waterproof mortar) is not less than 20 mm.

1) Mix "Laoyal" with cement to form a waterproof mortar, and paint it once or twice on the base surface with a total thickness of 2 mm.

2) After 20 minutes of waterproof mortar, mix it with "Laoyal" with cement and sand to make a waterproof mortar and wipe it on the surface of the waterproof mortar, with a thickness of 18 mm.

3) After 24 hours of waterproof mortar solidification, sprinkle water for curing. It is not recommended to do it yourself, but to do it by hiring a professional, you can understand this and see if others do it.

1. Find the original waterproof layer. Since the waterproof layer is not exposed, but is in the lower part of the surface layer, it is necessary to eradicate the surface layer and find the original waterproof layer. After the original waterproof layer is eradicated, the water stored in the original lower insulation layer is drained, and some exhaust holes are set up to do the exhaust method to drain the water in the insulation layer.

Then it is necessary to do slope treatment, do not form part of the roof water storage, usually set up cement mortar leveling slope, slope is not less than 3. Mul.

2. If in the case of rehabilitation and beautification, the waterproof layer that needs to be done must be a root-blocking waterproof layer, and the root-blocking waterproof layer has a modified asphalt membrane root-blocking waterproof layer, as well as a polymer membrane root-blocking waterproof layer. After the waterproofing is done, it is necessary to carry out a closed water experiment, and the water leakage is qualified, and then the maintenance and paving veneer brick decoration are carried out. In the end, in the case of landscaping and civil engineering cross operations, try not to damage the waterproof layer of the lower part, once damaged, the open-air balcony should be repaired in time.

Clean the base surface first, and then level with cement mortar, wait for the leveling layer to dry, paint K11 or JS polymer waterproof coating, brush twice, the first time to dry and then brush the second time, the two times the direction of brushing should be opposite, into a vertical shape, so that the brush can be in place, will not miss the brush.

It's the same, just use JS paint brush.

You can choose to use a slightly better waterproof material to do waterproofing, it is recommended to brush the waterproof material at a moderate height, and then the balcony floor can be paved with floor tiles, with permeable and impervious can be. Generally, permeable floor tiles are more economical. If you are worried about water leakage, you can brush the waterproof material several times and fill it with water for waterproof experiments.

First of all, deal with the base surface of the terrace. The base surface is treated into a firm, flat and clean surface, free of dust, greasy, wax and other debris substances; If there are pores, cracks and inequalities on the base surface, it must be repaired and smoothed with cement mortar in advance to ensure that the base surface is fully wet, but there is no open water;

Clause. 2. Choose waterproof materials suitable for home decoration. Waterproof materials are recommended to choose a tender polymer cement-based waterproof coating slurry, that is, the name on the market is: flexible, JS waterproof coating slurry, this kind of product is water-based coating, non-toxic, harmless and pollution-free, simple and fast construction, and cement substrate bonding tightly, long service life, strong waterproof effect, moderate price and other significant characteristics.

Third, pay attention to the waterproof construction in place. Do a good job of drainage slope with a slope of 3°; The flexible waterproof coating is painted twice before and after the word "ten", and the total thickness does not exceed 2;

Fourth, do a good job of protective layer. Make a cement mortar protective layer or paste tiles on top of the finished waterproofing layer.

If you do the above four points completely, you will definitely be able to achieve the waterproofing of the terrace without any leakage!

If the conditions allow, such as water and water, you can place a washing machine, of course you need to do waterproofing, many customers like the balcony living room to pave the past, it seems that the effect is better, the space is larger, in fact, we have to do it must place a door stone, just in case, water penetrates into the living room, can resist it, if you don't put the washing machine, there is no need to do, a small amount of water will not penetrate.

It's better to treat it with waterproof paint! Shanghai solid blue waterproof!

First clean the base layer, brush waterproof, closed water test to see if there is leakage, and then use 1 to 2 waterproof mortar leveling mixed with 3% waterproof powder, and pave the floor tiles.

Lay a waterproof non-woven fabric on the ground and paint it with a mixture of cement and 107 waterproof glue, especially the joints must be painted well. Conditional re-laying of floor tiles.

The forest is big, and there are all kinds of birds!
