Is there a leak in the balcony downstairs?

Whether there is water on the balcony will leak downstairs depends on how waterproof the balcony is. Naturally, there will be no problem. If waterproofing is not done well, it will inevitably leak downstairs for a long time. Therefore, when decorating the balcony, everyone must do a good job in waterproof and drainage of the balcony.

What should I pay attention to in balcony waterproofing?

1. Doors and windows need to be sealed.

If your balcony belongs to a closed balcony, be sure to close the doors and windows of the balcony whenever it rains. At the same time, it is necessary to ensure that doors and windows have good sealing performance.

2, the height and thickness of the waterproof layer of metope

Usually, the painting height of balcony waterproof coating should be at least 30cm. If it is the area where the washing machine is placed, the waterproof paint needs to be painted higher. If your balcony belongs to the exposed balcony, in order to strengthen the waterproof effect, it is best to make a high point, and the thickness of waterproof coating needs to be above1.5 mm.

3, the ground should have a slope.

The open balcony is easy to get water when the rainstorm comes. In order to prevent rainwater from entering the room, we need to have a certain slope when decorating the balcony to ensure that the water can flow smoothly to the drainage hole and will not enter the room.

4. Install a floor drain with smooth drainage.

In stormy weather, if the rainfall is greater than the drainage capacity of the floor drain, there will be a lot of water on the balcony floor, which will easily lead to water entering the room. Therefore, when we choose the balcony floor drain, it is best to choose the floor drain with large displacement and smooth water flow.

5. Choose a waterproof coating with good performance.

Usually, the waterproof layer of the balcony is on the outer layer, which will be tested by natural weather such as sun exposure, rain, cold and heat. Without excellent performance and good protective measures, its service life will be greatly shortened. Therefore, when purchasing waterproof materials, it is necessary to choose waterproof coatings with high strength and aging resistance.

What are the waterproof materials for the balcony?

1, polyurethane waterproof coating

Polyurethane waterproof coating is a kind of waterproof material with very high film forming property, which can be applied on complex base and form a continuous, elastic, seamless and complete waterproof layer. This waterproof material has good adhesion to various base surfaces and good elongation, and can adapt to the slight vibration, expansion, deformation and cracking of the base under the action of external force. Its stability, waterproof effect and product quality are favored by consumers, and this material is also popular.

2, acrylic waterproof coating

Acrylic waterproof coating, like polyurethane, has good curing speed and better environmental protection performance than polyurethane coating. The product is also very convenient to use.
