Anonymous users2024-01-24Hello landlord: If your home is the top floor, you have to make the roof waterproof as a whole, because since it can be a crack in the waterproof layer, it is difficult to say that it will not crack the second one in the future, indicating that the waterproof quality is not good!! Generally, waterproofing is calculated by square meters!!
So you need to check with local businesses! (Remember, if your home is a commercial house, you can find a developer or property maintenance, this thing is not your own).
Answer 1: If the bathroom uses sewing agent, you need to use a utility knife to make a groove in the gap; 2. Use a penetrating waterproof agent to evenly apply it to the cement; 3. After the waterproofing agent is dry, fill the gaps with caulk; 4. Use plastic steel mud to make waterproof edges on the connection of the wall and the ground and the pipeline; 5. Do not touch the water within one day after the end of the project. Ask questions.
1. Inspect and accept the appearance, variety, specification, packaging, size and quantity of materials, and form corresponding acceptance records. >>>More
The judgment method is very simple, plug the floor drain, and then release water on the ground, pay attention to the observation of the water leakage downstairs after 40 minutes, if the water leakage downstairs is serious, it is determined that the waterproof layer is leaking.
The problem of the waterproof layer is certain, otherwise it will not leak downstairs. >>>More
