Bathroom waterproofing process announced! Doing these 4 points is the correct construction method

The waterproofing project of the bathroom needs to pay attention to the following points:

The first step: waterproof material painting

When renovating the bathroom, choosing the right waterproof material is crucial.

A good waterproof material should have a variety of characteristics, such as waterproof, moisture-proof, wear-resistant, corrosion-resistant and so on.

These features can ensure that the bathroom will not leak, mold and other problems in a long time, thus ensuring the service life and comfort of the bathroom.

Waterproof coating is a common waterproof material, which can be coated on the walls and floors of the bathroom to form a waterproof membrane to prevent moisture penetration.

Waterproofing membrane is also a commonly used waterproofing material which is often used on bathroom floors to prevent moisture leakage.

In addition, waterproof adhesive is also a good choice, it can be used to fill the gaps in the bathroom to prevent moisture leakage.

Choosing the right waterproof material is a very important step in bathroom renovation, and only by choosing a reliable quality waterproof material can you ensure the comfort and longevity of your bathroom.

Step 3: acceptance of the waterproof layer of the bathroom

01, to check the quality of waterproofing materials and construction technology is in line with the standard requirements, including the thickness of waterproof coating, painting uniformity and so on;


02, to check the integrity of the waterproof layer and no leakage phenomenon, can be tested by water pressure test or use professional testing instruments;


03, to check whether the drainage system of the bathroom is normal, as well as whether the sealing of the floor drain and drain pipe is good. Only through strict acceptance can ensure that the bathroom waterproofing effect meets the requirements for the family living environment of health and health protection.


In addition to acceptance, bathroom waterproof layer maintenance is also critical. Regular maintenance can extend the service life of the waterproof layer to ensure its integrity and reliability.

Step 4: Specific maintenance measures

Clean the bathroom regularly to avoid the accumulation of limescale and stains;


Avoid scratching on the waterproof layer or using sharp tools to damage the waterproof layer;


Avoid placing overweight items on the waterproof layer to avoid crushing the waterproof layer;


Regularly check the drainage system of the bathroom, and promptly clean the blocked floor drains and drainage pipes.


Do a good job of maintaining the waterproof layer of the bathroom, in order to ensure its long-term reliability and effectiveness of use.

What are the waterproofing materials for home improvement?

  1. Flexible mortar


The ratio of mortar to emulsion mortar is 533604, which is flexible and will not affect the waterproof effect even if the grass-roots level is deformed and cracked. This kind of mortar is mostly used to face the wall, bottom and other water surfaces, because its elasticity can well adapt to the deformation of the grass-roots level, while maintaining the waterproof effect. For facing water surfaces such as the top surface, it is necessary to use a hard mortar due to its high load bearing weight.

  1. Rigid mortar


Also known as rigid mortar, emulsion and mortar ratio of 1,333,604. after many times of pressing, the coating does not need to be processed, can be directly affixed to the brick, convenient and quick. Cured trip cement full of eyes, will not pack seepage, back surface waterproof effect is very good. This mortar is suitable for facing the top and other water surfaces, because of its hardness can be very good to carry the weight, while maintaining the waterproof effect.

  1. Polyurethane


It can be used indoors and outdoors with a very thick brush of about 3 millimeters and an elasticity of over 300%. Any cracking of the substrate will not cause it to split, so it has a good waterproof effect. Polyurethane is gel-like and very thick, so it takes a lot of effort to use a squeegee during construction, but its waterproofing effect is very significant and it can protect the building from water very well.

  1. Coil


Coil waterproofing company said that most of the waterproof coatings on the market belong to water-soluble materials, whether water-soluble or oil-soluble waterproof coatings, as long as the relevant national environmental protection certification, such as the China Environmental Labeling Certification or CTC product environmental quality certification, these materials are environmentally friendly and reliable. Therefore, consumers in the choice of waterproof coating, according to their needs and budget, choose products that meet environmental standards.


  1. Acrylic waterproof coating


Waterproofing company said, acrylic waterproof material is made of pure acrylate copolymer or pure propionate emulsion, with the appropriate amount of high-quality fillers and additives, belongs to the synthetic resin one-component waterproof coating. It is a water-soluble coating, can be diluted with water, convenient construction. After the film elasticity and ductility, waterproof effect is remarkable, the price is moderate, is a cost-effective waterproof coating.

What do you have to do to waterproof your bathroom and what do you look for?

Proper waterproofing construction steps can greatly reduce the occurrence of these problems. When applying waterproof paint, pay attention to both sides must be brushed, so as to ensure the overall effect of the later. The steps for waterproofing the bathroom are as follows:


01, check before construction


If it is a new house renovation, waterproofing companies will generally require waterproofing sample room for water closure test, in order to check whether the building structure has a leak. But now when the house is handed over, this step has generally been done, you can choose whether to redo.


In the case of a used house, a water closure test is theoretically required. However, due to the length of time, the house has a high rate of leaks


In the event of a leak, there is a danger that it will seep into the installed house downstairs during the test.


02, when backfilling, pay attention to the secondary drainage pipe tilt


so that if there is standing water after the brick joint treatment, it can be drained in time to prevent odor. Next, carry out the first level treatment. Ground treatment must first level the ground, otherwise it will lead to uneven thickness of waterproof coating, later cracking and leakage.


03, wall treatment


Wall treatment, the wall should not have sharp protrusions, sharp burrs, sand holes, large pebbles, the base surface should be flat, smooth and firm. Connection with the pipe foundation and dead ends should be polished into rounded corners. Then, apply the first layer of waterproofing. The point of this painting is to use even strength and no air bubbles. The order is wall to wall, inside to outside. Drainage pipe intersections and corners should be emphasized, and the thickness of the waterproofing coating should be in accordance with the requirements of the waterproofing products used.

04, coating the second layer of waterproofing


Waterproofing company said, when applying the second layer of waterproofing, pay attention to ensure that the first layer of waterproofing completely dry and film. If the first waterproofing is not dry, the second waterproofing will greatly reduce the waterproofing effect.


05, coated with a protective layer


In order to prevent the subsequent structure damage to the waterproof layer, waterproof coating surface to apply a protective layer. The protective layer covers the waterproof layer and shall not have leakage. It is firmly attached to the base without cracks, bubbles and flaking. In this way, the waterproofing of the bathroom is completed.

Bathroom waterproofing is a non-negligible part of building construction, and proper construction methods are critical to protecting the structural integrity of the home and the quality of life of the occupants!
