It is very important to waterproof the bathroom. If it is not done well, it may even affect the normal life of the neighbors. So, how to waterproof the bathroom so as not to leak? What should we pay attention to when doing waterproofing? Let’s take a look at it together!
How to waterproof the bathroom?
(1) Basic treatment
Before waterproofing, we must first ensure that the ground is clean, flat, free of dust and other debris. If there are gaps, cracks, or inequalities on the ground, we should use cement mortar to repair and smooth it in time.
(2) Brush waterproof paint
Before brushing the first layer of waterproof paint, make sure the ground is dry. The waterproof paint should be applied to the entire ground, leaving no space, and the height of the painting should be the same. After the first coat of paint is dry, apply the second coat of waterproof paint coating.
When brushing waterproof paint, we must wear soft-soled shoes. After the paint is painted twice, we must protect the finished product and do not allow people to walk around.
(3) Lay a protective layer
The waterproof layer is relatively fragile. In order to prevent the damage to the waterproof layer in the future construction, we should lay a protective layer on the surface of the waterproof coating.
But when laying the protective layer, we must pay attention to whether the laying is in place, whether there are any omissions, whether there are cracks and air bubbles, if any of these problems exist, we should remove them and re-pave them, and must not cut corners.
(4) Closed water test
The closed water test is an essential and important construction step. After the waterproof construction is completed, the water storage test is carried out, and the highest point of the ground water level cannot be lower than 2cm.
After more than 24 hours of testing, if there is no leakage, it means that the test is qualified. Otherwise, we will do it again, and we must not be careless.
What should we pay attention to when waterproofing the bathroom?
(1) Try not to damage the original waterproof layer
Before doing waterproofing, we try not to damage the original waterproof layer. If the waterproof layer is accidentally damaged, it is best to repair it in time to prevent potential safety hazards in the future.
(2) Be sure to clean up the ground
Before painting the waterproof coating, be sure to clean the ground. If there are cracks, gaps, etc., you must first fill the ground with cement mortar.
(3) Waterproofing should be done on walls, floors and grooves of water pipes
When waterproofing, people tend to roughly waterproof the grooves of the water pipes, or even forget to waterproof the walls. These are not desirable. No matter where it is, it must be carefully waterproofed.
(4) The duration of the closed water test should be up to 20h
People often think that a few hours are enough when testing the waterproof layer, which is wrong. The closed water test must be tested for 24 hours to know whether it leaks or not.
The above is a brief introduction on how to waterproof the bathroom and the precautions, I hope it will be helpful to your home improvement.
