How to deal with water leakage in the wall around the balcony window

Causes of water leakage in the wall around the balcony window:

1. The reason for aluminum alloy windows.

Aluminum alloy windows are exposed to sunlight and rain for a long time, and it is easy to have problems such as aging, hardening, and cracking of sealing strips. The aluminum alloy window does not have a drainage channel, which will cause the rainwater to not drain out, causing water pressure and leakage along the wall.

2. Reasons for window and wall construction.

During the construction of aluminum alloy windows and walls, there were no construction personnel in the beams who did not fill the waterproof materials as required, resulting in gaps between the aluminum alloy window frame and the wall, resulting in water seepage on the wall.

3. Reasons for waterproof construction.

Some owners just make the balcony waterproof, and also change the balcony to a closed room, and put the washing machine on the balcony, which can easily cause the balcony to leak.

4. The connection between the door and window and the wall is not tightly sealed.

There is no olecranon and drip line on the window ceiling, and the outdoor window sill plate is higher than the indoor table. The outdoor window sill plate is not sloped downstream, resulting in water backflow.

Balcony windows are waterproofed.

1. Base surface treatment is the foundation.

Base surface treatment is a key point in construction, and it is necessary to ensure that the ground is flat, clean and free of debris before construction. If there are problems such as pores and cracks, they should be repaired with cement mortar, and the yin and yang corners should be wiped into an arc shape.

2. Pay attention to the painting method.

In the brushing, it is necessary to pay attention to the strength to be even, to maintain the angle of the vertical first intersection of the weeping oak rock, and to fully cover the jujube in place. The word painting should not be too thick, especially at the nozzle and corner, not more than 1mm, so as to avoid cracks after drying.

3. Maintenance and protection are also important.

After 24 hours of construction, it is necessary to cover the coating with a damp cloth for maintenance, and only step on it after it is completely dry, and pay special attention to not destroying the waterproof layer when installing sanitary ware in the later stage.

4. Carefully check to prevent future troubles.

After the completion of the painting, it is necessary to inspect to prevent future troubles, compare the test for 48 hours after the completion of construction, increase the closed water height as much as possible, not less than 3cm, carefully check whether there are traces of water leakage on the downstairs ceiling, and the lightweight wall must be sprayed with water to check the back wall.

Hello, the simple way to deal with the leakage of the window sill in general is:

1. Clean the base surface and moisten it thoroughly.

2. Fill the gaps with caulk if there are obvious cracks.

3. Brush three to four times with acrylic high-elasticity anti-crack waterproof coating along the aluminum alloy frame, and the next time the surface can be painted after each surface drying.

Note: If there is an anti-theft net, the nail that fixes the anti-theft net must be sealed with paint.

In fact, it is better to find a professional to help you deal with it! In the future, choosing a better decoration company before decoration will also reduce this kind of problem!

When the owner replaces the window or seals the balcony, due to improper operation, the rainwater will penetrate into the interior through the connection between the window or window frame and the exterior wall. According to the actual situation, the following processing can be done:

1. The dripping eaves were damaged

1. Phenomenon: There are dripping eaves at the window openings, and when the balcony is renovated, some owners move the windows outward and press them to the dripping eaves, and the rain will enter the cracks of the window frame and the wall, and the water will flow from the upper part of the window.

2. Solution: Install drip eaves at the entrance of the hole (through connectors or glue bulges and other forms) so that the water can be discharged smoothly.

Second, the drainage hole is blocked

1. Phenomenon: The bottom of the plastic steel window is equipped with drainage holes, but if you don't pay attention to it during installation, it will be blocked, and once there is heavy rain, the water in the window frame will seep from the installation of the expansion bolt.

2. Solution: Check whether the window is connected by the expansion bolt, if it is possible, it can be temporarily glued to the inside to seal it, and then re-glued after the rainy season. If it is fixed under the glass, it is necessary to wait until the rainy season has passed, open the glass, remove the water in the window frame, and then re-apply the glue.

3. Water leakage caused by loose and deformed windows

1. Phenomenon: Water leakage caused by loosening between the window and the frame is the most common cause. On the one hand, when the door is closed, the window will also resonate and vibrate, and the gap between the window and the wall will become larger and larger over time; On the other hand, it is caused by the poor quality of the window, the strength of the poor quality window is not enough, it is easy to deform, and the mortar layer at the edge of the window frame will crack and fall off soon after use, which will cause leakage.

2. Solution: If the water leakage caused by the quality of the window itself is damaged, it is necessary to directly repair or replace the window. The quality of the purchased window frames, window sashes, sealing strips, etc. should be passed, and the waterproof sealing materials used should have material quality certification documents to ensure that the quality of the materials meets the requirements, and do not choose inferior sealing materials.

Fourth, the waterproof layer of the wall near the window is damaged and causes water leakage

1. Phenomenon: In old houses with a long age, the waterproof layer of the wall around the window is damaged and prone to water leakage; In addition, when the windows are replaced in the renovation of the old house, the damage of the waterproof layer of the exterior wall caused by the unprofessional removal of the windows, and if it is not repaired in time, it is very likely that there will be water leakage after the installation of new windows.

The exterior walls were seeping water.

Remove the wall tiles of the external wall and smooth the cement mortar; The horizontal slope of the outer window sill should start from the inside of the lower opening of the window (window frame) and end above the façade; All should be painted and smoothed; Paint with cement-based waterproofing paint, especially on the level of the window sill. Then re-pave the exterior tiles, don't cut corners. Waterproofing materials can only be used cement-based, and others cannot be used.

After this is done, there is a glass glue to close the window frame and the tile (dark corner).

In addition, check whether there is any defect in the sealing of the expansion bolt fixing position when installing the window frame, and the water outlet on the outside of the window frame cannot be blocked by the exterior wall tiles.

Whether you need to dismantle the window depends on whether it can be painted, etc., and generally does not need to be disassembled.

Balcony windows do not need to be removed, and the treatment method is that there are loose ones on both sides of the window.

Place nailing, knock off the tile nails outside the window sill and knock off the lower mouth of the window, and use cement mortar to fill the window gaps, re-paste the tiles on the window sill, and wait for the ash to dry, and finally use glass glue to glue around the side of the window frame to close. After the removal of the tiles, there is a certain slope outward to ensure that the water flows outward.

Use the plugging spirit and JS composite waterproof paint and putty to wipe the combination of the window and the wall into a figure-eight shape, and then use the JS composite waterproof paint to paint twice It should be no problem.

There is a liquid anti-leakage agent that fills the gaps in the tiles and works well, and the plugging agent also works. Give it a try.
