In the current home decoration, people generally block the balcony, especially those who have children and the elderly at home and those who live on the ground floor of the building. Only in this way can we better ensure safety. However, there are many and miscellaneous manufacturers sealing the balcony, and we often hear customers' complaints about the phenomenon of sealing the balcony, so what are the main reasons and how to solve it? Now let's talk about the maintenance methods of balcony leakage and precautions for balcony waterproof decoration

in today's home decoration, people generally block balconies, especially those with children and the elderly at home and those living on the ground floor of the building. Only in this way can we better ensure safety. However, there are many and miscellaneous manufacturers sealing balconies now, and we often hear customers' complaints about the leakage of sealing balconies. What are the main reasons and how to solve them? Now let's talk about the maintenance methods of balcony leakage and precautions for balcony waterproof decoration

reasons for balcony water leakage

first, the window frame under the balcony plastic steel window has a drainage hole connected with the outside world. Its function is to collect the rainwater flowing along the surface of the outer window into the groove of the window frame under the window opening leaf, and then discharge it to the outer window sill through the drainage hole, and then to the outside. This drain hole is required not to be blocked, otherwise the rainwater in the window frame under the window opening fan will leak into the indoor windowsill and into the balcony railing along the gap between the windowsill plate and the window frame; The drainage hole must be higher than the plastered surface of the outer windowsill to realize the drainage effect

second, the window sill outside the balcony must protrude from the outside of the balcony railing, and a “ must be plastered on the lower part of the protruding; Reverse slope ”, It is called dripping slope to avoid rainwater flowing along the surface of balcony breast board and increase the chance of leakage

third, there should be a gap of no less than 5mm between the periphery of the window frame and the plastering, and the elastic building sealant should be used to caulk the gap to block the channel that may leak. Because the sealant ages quickly, if it has lost elasticity, it should be removed and replaced

maintenance method for balcony leakage

first chisel a gap of 1 cm wide and 1.5 cm deep in the outer window, then clean it up and sprinkle some water to fully wet it Use plugging king to make it into putty, pour it in and smooth it, and sprinkle some water for curing after it is dry (prevent cracking) after completion, brush two to three times of waterproof paint (the one with very good flexibility)

treatment method

1. Remove the decorative layer, thermal insulation layer and leveling layer of the external wall along the periphery of the window

2. Remove the sealing materials and other materials filled at the interface between the window and the external wall of the structure

3. Remove the sundries in the joint between the window and the structure, and use a blower to blow them away

4. Refill the inside of the seal with styrofoam, insert sealing paste, and seal and level the outside with plugging treasure

5. Paint the exposed UV resistant waterproof film in the leakage range

6. It is qualified if there is no water leakage in the final watering test, and finally restore the insulation layer, crack resistant mortar and exterior wall decorative layer of this part

7. Considering the actual situation of the project, as the house is an old-fashioned house, the developer's construction quality problems require that the adjacent upstairs parts be painted with waterproof coating (without grooving)

remember to do it inside at the same time, so it can be solved. The waterproof key around the window is the outer opening, because water comes from the outer wall. After filling the middle gap with expansion agent, silicone sealant shall be used outside to ridge the gap. The depth shall not be less than 1.5cm, and the width shall not be less than 0.8cm. This is the key. To meet this requirement, relying on the elasticity of silicone glue, we can deal with the small cracks caused by the deformation of the window

first of all, if the balcony leaks, you should first find the leak, and start from there, mainly from the high part of the roof to the low part (because the water flows to the bottom). First, you should check whether the roof has cracks, whether the original waterproof layer has aged, and whether the original SBS waterproof coiled material on the roof has bubbles. If there are bubbles, it proves that the water has entered the bottom of the waterproof layer, so there is water leakage And whether the gutter on the roof is blocked In rural areas, there are still a large number of tiled houses. When there is roof leakage due to broken tiles, just replace the tiles. This step is also known as “ Leak ”. Secondly, if the roof is not waterproof before, you only need to remove the leaking part 2~3cm deep and clean it, then you can pour it with asphalt. Now there is a finished asphalt coating, and when it is sunny, it will basically not leak. If there is a waterproof layer, it is more troublesome. Remove the waterproof within the surrounding area and make it waterproof again. When doing it, pay attention to make a reinforcing layer at the junction with the original waterproof

precautions for balcony waterproof decoration

the first waterproof door and window is the balcony. The quality and sealing of doors and windows are good, and the inside and outside directions of the waterproof frame should not be mistaken

the second waterproof barrier refers to the waterproof of the balcony floor. The ground is waterproof. First of all, there must be a certain slope, and the lower side is the drain. In addition, the balcony and living room should have a height difference of at least 2 cm. It may be difficult to maintain such a height difference, because the actual height difference may be only about 1 cm. Then, you might as well use a stone slab for decoration, and use cement and leak patching spirit at both ends and below the stone slab to plug the joints and prevent leakage, which is both beautiful and practical

the third waterproof barrier is to keep the balcony floor drain unobstructed. In rainy days, when the rainfall is greater than the drainage capacity of the floor drain, it is possible to form ponding on the balcony ground. When the water volume is too large, it is possible to overflow the waterproof frame of the sliding door and enter the room. Although it is unlikely, it also happens occasionally, so we have to prevent it

the joint on the edge of the closed part of the balcony should be treated with waterproof and seepage prevention, including the four sides of the closed body. In addition, it should be noted that there should be an outward slope on the lower side of the closed window to prevent water seepage
