There are many drops of water in the bathroom on the top floor. What should I do?

1. Dig the leaking part 2 ~ 3 cm deep, then clean it up and water it with asphalt. Now there is a finished asphalt coating. If it is treated in sunny days, it will basically not leak.

2. Usually, the leaking place is the joint between boards, so the simple and economical way to repair the leakage of rural bungalow roof is to lay a layer of asphalt joint on the roof, but this method is not durable, and the more durable way is to coat the left waterproof layer or latex on the roof.

3. Brush twice with water-based waterproof coating or transparent waterproof material infiltrated into the wall. If the gaps are polished, the broadband should reach more than 20 cm. This ensures adhesion. Waterproof coating is permeable and bonded, with good elasticity and long service life. If the roof information is special, such as rubber, which is not suitable for waterproof coating, you can choose other waterproof information.

4. The traditional idea of building a leaking collector is to make up for the leaking place. The latest waterproof and leak-proof method is to abandon this traditional concept. If the waterproof layer leaks, it is necessary to do a good job of waterproofing and leakage prevention outside the tiles. As long as the surface of the tile outside is waterproof, the waterproof effect is the same.

Solution of indoor ceiling leakage

1. Repair joints. Most of the leaks on the top floor are cracks. You need to fill the gap with Yi Jia leak paste, and then proceed to the next step when it is dry. (If the joint is less than 1MM, no leakage sealant is needed. )

2. Brush it twice with water-based waterproof coating or transparent waterproof material with wall permeability, which is comprehensive. If the gap is polished, the broadband should reach more than 20 cm. This ensures adhesion. Waterproof coating is permeable and bonded, with good elasticity and long service life.

3. If it has not been done before, and it is a new cement roof, the most appropriate way is to make the base first, and then choose a more qualified SBS waterproofing membrane to pave it again. One or two barrels of base oil is enough, and thirty or fifty yuan is enough. SBS is better. Polyester tires should be used for mm thick tires, polyester tires should be used for 4mm thick tires, and compound tires are also acceptable.

4. If it has been done before, most of them are paved with SBS waterproofing membrane. If it has been more than 67 years and the surface is seriously damaged, SBS can only be resurfaced. If the time is short and the damage is not very severe, then buy one or two barrels of oily polyurethane waterproof coating and apply it on the damaged place once, which can be used for two or three years, saving time, money and labor.

5. The leaking point of the roof is generally in the shape of water outlet and joint, so these details must be handled well during construction, which will be much safer. The effect of self-made is not good, and the later maintenance is troublesome, which affects the overall effect. If there is any problem, I need to find a professional maintenance team to deal with it.

Extended data:

In a narrow sense, waterproofing and leakage patching is the construction of indoor and outdoor waterproofing treatment of buildings and the leakage patching of indoor and outdoor leakage parts. Broadly speaking, this is the waterproof treatment of space objects and the treatment of liquid and liquid leakage.

Waterproof and leak-filling, the traditional idea is to fill the leak. The latest waterproof and leak-proof method is to abandon this traditional concept. If the waterproof layer leaks, it is necessary to do a good job of waterproofing and leakage prevention outside the tiles. As long as the surface of the tile outside is waterproof, the waterproof effect is the same. Construction method of waterproof and leak-patching: remove waterproof cement or glue between tiles with a knife, dry the floor with a dryer for one day, and then fill the ravine with cement of the same color as the floor.

Construction operation

1. After the base is cleaned, the key parts such as the angle of yin and yang, expansion joints and construction joints should be treated first. Especially for the parts that are not easy to be painted such as drainage holes, it is necessary to strengthen the painting of waterproof primer for 2-3 times.

4. Prepare waterproof coiled materials, and the adhesive coiled materials of waterproof coating, primer coating and coating film must be distinguished. Priming. In order to improve the adhesive force between the waterproofing membrane and the base, the primer can be applied repeatedly, evenly and thoroughly, and fully penetrated into the concrete base to improve the adhesive strength and shear strength.

13. Waterproof coating must be prepared according to the product description, and the ratio is A:B=2: 1, and the amount of preparation each time matches the actual amount on site.

4. Waterproof coating should be stirred evenly for about 3-5 minutes until the mixture of component A and component B is uniform.

5. The evenly mixed waterproof coating should be painted according to the area to be painted on site, and the basic coating should be greater than the area of the bonded coil. The waterproof coating shall not exceed 30 minutes at the latest from the end of mixing to the end of brushing.

[6] After the first coating, it takes about 4-8 hours to coat the second and third coatings again. The thickness of the first coating is 0.5 mm, the thickness of the second coating is about 0.5 mm, and the thickness of the third coating is about 0.5 mm. Only after the first coating is completely cured can the second coating be applied again.

First, when the coiled material is bonded, the second coating should be completely cured before construction (waterproof coating can be painted or sprayed several times according to the actual situation and thickness requirements of the project site, remember to finish it at one time).
