How to waterproof the balcony needs to be waterproofed

1. The waterproofing of the balcony sliding door is in the south, and the construction technology of the balcony sliding door is often the key to whether the home can survive the rainy season. First of all, we should pay attention to the quality of the door, the sealing should be good, and the inside and outside direction of the waterproof frame should not be mistaken. If the balcony has no windows at all or the windows are not well waterproofed, then it is the turn of the second waterproofing line.

2. The balcony waterproofing should first ensure that the ground has a slope, and the low side is the drainage outlet. Then make sure that there is at least a height difference of 2 3 cm between the balcony and the living room or the balcony and the living room. It is actually difficult to achieve such a height difference between the living room and the balcony, because the height difference of the building itself may only be about 1 cm.

It is recommended to use a marble slab for decoration, which is both practical and beautiful. Of course, both ends and below the slate must do a good job of plugging joints and preventing leakage, and use cement to plug the leakage spirit or water without leakage.

3. The balcony waterproof should be done in time to keep the balcony floor drain smooth, and the balcony floor should ensure the smooth drainage system, especially when the balcony has plants, it should be cleaned regularly to prevent the floor drain from being blocked during drainage, so as to prevent water from penetrating into the living room. If there is artificial lighting in the garden, it should also be waterproofed, especially the lamps and anti-leakage switches, so as to avoid damage caused by leakage in rainy days.

The balcony is needed to do waterproofing. 1.The first layer is made of flexible waterproofing, such as K11 waterproof slurry flexible type.

2.The second time do mortar waterproofing (mortar waterproofing agent) as a protective layer. Open balcony waterproofing can not use a single waterproof material, must be rigid and flexible combination construction, flexible waterproof stretch is good, a little settlement or deformation will not damage the waterproof layer.

Rigid waterproofing (i.e., mortar waterproofing agent) can play a protective role while waterproofing, and the waterproof layer is not easy to be damaged.

First of all, waterproofing needs to be done on the cement substrate, and it is necessary to do a good job of waterproofing before tiling. Now the market can be advertised on the floor tiles to do waterproofing, and the waterproof effect is still good are the gimmicks of business publicity, and there is basically no waterproof effect on the tiles. There are two more common ways to do waterproofing on the terrace, one is to use waterproof membrane, and the other is to combine waterproof coating and mortar waterproofing agent for construction, but considering the construction difficulty, waterproof effect, budget cost and other factors, the latter is now more widely used.

Because the terrace has to accept the erosion of the sun and rain for a long time, the requirements for waterproofing are higher, so it is recommended to combine the construction of rigid waterproof + flexible waterproofing, that is, first paint the flexible type of K11 waterproof slurry, and then make a protective layer of mortar waterproofing agent, which not only has flexibility, but is not easy to powder and crack, and at the same time has high strength, and the puncture resistance and waterproof effect is of course better.
