The waterproof details you don't know are hidden here!

Key points need to be waterproof

In the waterproofing works in the bathroom and kitchen, there are some details that are particularly noteworthy - these places have more contact with water, and are easily overlooked in waterproof construction, such as floor drains, small water pipes and floor joints, toilet pipes, etc. It is the most leaking part of the bathroom, and it needs to be waterproof.

Guaranteed number of layers and thickness

The construction of the waterproof layer requires special fine work to avoid the cut-off of work. The thickness of the waterproof layer directly affects the quality of the waterproof engineering in the home, and the number of layers to be painted needs to be guaranteed. The waterproofing of the bathroom generally needs to be brushed 2-3 times. Wait for the first time to dry and then brush for the second time. The floor and wall of the bathroom (return height is not less than 1.8 meters or full), the floor of the kitchen and balcony. The wall surface (return height is not less than 0.3 m), all the floors and walls of the first floor house (returning 0.3 m high), the ground floor and all wall surfaces of the basement should be waterproof and moisture-proof.

Do a good job in water shut-off test

After the waterproofing of the bathroom is completed, it is necessary to conduct a water shut-off test to check whether the ground leaks by maintaining the state of water storage for a period of time.

Before closing the water, first block the drain point and the threshold of the floor drain to prevent the water from flowing out of these parts after starting the water storage. After blocking and releasing water, the depth of the water should be more than 2cm, and the test should be at least 24 hours (at least 48 hours in winter). During this time, observe whether the water surface drops significantly. In particular, check whether the top of the downstairs bathroom leaks. If the test fails, you need to do another waterproofing.

Choose safe and environmentally friendly materials

Although the waterproof project is invisible, it is closely related to the health of the home. In the choice of waterproof coatings, it is best to choose large brands, quality guaranteed products, some inferior waterproof coatings will use toxic raw materials to save costs, once the toxic waterproof coating is applied, it will volatilize poisonous gases all the year round. Consumers should avoid the waterproof layer becoming an invisible killer in home improvement.
