    Balcony decoration waterproofing project is a key project. The balcony is exposed, in addition to direct sunlight, rain will also cause some erosion to the balcony, so pay attention to the waterproof and leak-proof balcony.

    How do you waterproof a balcony? Balcony waterproofing is the treatment of the base layer of the balcony. The base treatment is firm, flat, clean and dust-free, and the ground is free of any debris.

    Problematic cracks and unevenness can be repaired with cement mortar, plugs, etc. Make sure the base layer is well moistened and free of water. Choose waterproof materials suitable for balconies, such as Langkawi's flexible JS waterproof coating, which is a water-based coating, green use, harmless to the body, easy to construct, and most importantly, good waterproof effect.

    In addition, balconies with sliding doors should pay attention to the quality and tightness of the sliding doors, and for southern families, it is more important to prevent rainwater from penetrating outward when the rainy season comes.

    The construction method of the waterproof layer is the same as that of toilets, kitchens, etc. The most important thing is to do it well, and the details cannot be ignored. The water-repellent coating should be applied evenly twice.

    In addition, when the balcony ground is waterproof and blocked, in addition to the drainage outlet, it is necessary to ensure that the ground has a certain slope towards the drainage outlet, and the lower end is the drainage outlet. The height difference between the balcony and the living room should be 2-3 cm to prevent rainwater from backflowing. It is also essential to have a protective layer of waterproofing, which needs to be protected with cement mortar or tiled.

    Due to the poor waterproofing of balcony windows when installed, rainwater is easy to stay in the window frame from the guide rails, including the blockage of the drainage holes in the window frame, which is easy to flow into the room. When decorating, special attention should be paid to the sealing and waterproofing of the windows after installation. Later, check whether the drainage holes of the balcony window frame are blocked.

    Many old neighborhoods have flat roofs, and drainage outlets may block some plastic bags and bird nests. In the case of short-term showers and torrential rains, poor drainage is very easy to cause backwater, which in most cases affects the users on the top floor. In this case, before the rainy season, the drainage system of the property can be inspected on the roof to eliminate hidden dangers.

    Balcony air conditioning ducts, smoke exhaust ducts, etc. Open-air pipes, when drilling, try to tilt outwards to prevent water from backflowing. A rain cap can be installed at the outdoor outlet of the smoke exhaust pipe, and a check valve must be installed to prevent rainwater from flowing in through the pipe.

    How can we better deal with balcony leakage repair? During construction, the following aspects should be emphasized. Is the use of waterproof materials appropriate, and can the balcony leakage problem be solved in a targeted manner during construction?

    Is the designated construction master skilled and experienced? Is the construction economical, reasonable, superior and efficient in all construction stages? In order to make the waterproofing construction smoother, have you formulated a suitable waterproofing operation plan in advance, and have you designed construction drawings with high construction feasibility?

    Generally speaking, there are two reasons for balcony water leakage, one is that the balcony window is not sealed enough to cause water leakage due to rain. The second is because the balcony feng shui rain waterproof layer is aging and damaged, coupled with the lack of external insulation layer caused by the balcony leakage.

When there is extreme rainy weather, poor drainage pipe design will produce a series of hidden dangers. The balcony is a window to the outside world, and it is also more prone to water accumulation and leakage.

    Therefore, the drainage facilities of the balcony must be complete and comprehensive. Anyone with some life experience will understand that the balcony window is the most leaky. When decorating, it is generally chosen to reserve a two-centimeter gap under the window and then plug it with cement.
