Aluminum alloy door and window waterproof treatment method
First, because the aluminum doors and windows are generally recessed, the top of the window must be dripping olecranon to prevent capillary rain from occurring.
Second, aluminum alloy doors and windows around the 300MM from the window to be painted around the waterproof coating (asphalt), before doing the waterproof coating to be painted with the position of the ash after cleaning lead water and oil.
Third, the window should be sealed with concrete added with water repellent. Please be sure to add water repellent because ordinary concrete loses water due to moisture reaction during solidification. The inside is hole-shaped and water seeps into the room from the hole. , while the concrete added with water repellent is dense inside and will not seep. (And domestic use of foaming agent I do not know how the effect)
Fourth, waterproof sealant should be applied to the intersection of other materials around the window frame.
Fifth, all the tops of the opening windows should be filled with a drape to prevent rainwater from flowing into the room from the opening upwards.
Sixth, the glass and aluminum alloy frame should be filled with sealant, do not use plastic strips.
Seventh, it is better to design a boss at the bottom of the window. The surface of the boss is behind the glass surface so that the water collected from the surroundings will not flow down the window sill to the room.
Eighth, the glue between the sill plate and the window at the bottom of the window should be designed outwards instead of facing upwards, and the sill plate must also be designed with an outward slope.
Ninth, if it is a single glass, the condensing water diversion hole should be designed at the bottom of the glass at the bottom of the window.
Tenth, both sides of the window should pay attention to the second, third and fourth on it.
The construction should strictly deal with the interface processing. According to actual engineering experience, pay attention to the above ten points, doors and windows should not be leaked.
