When it comes to how to make the bathroom waterproof, you should be familiar with the basic steps of material selection, grass-roots cleaning, detail processing, large-area brushing, and water-proof test. However, the end of the closed water test does not mean that the waterproof construction of the bathroom has been completed, and the waterproof protective layer is also a very important step. Why do you need a waterproof protective layer, and how important is it?

Why do we need a waterproof cover?

According to the “Technical Specifications for Residential Indoor Waterproof Engineering”, after the indoor parts are waterproofed, a waterproof protective layer must be made. Because the waterproof coating film is generally only about 1.5mm thick, which is equivalent to a thin waterproof layer, it is easily damaged by external force erosion. After the bathroom waterproof inspection is qualified, follow-up constructions such as backfilling and paving tiles are needed. If the protection is not done in time, the later decorative construction will often cause damage to the waterproof layer and cause water leakage.

Take tiling, for example. When decorating a tile, the decoration master usually sticks to the wall first, and will directly step on the waterproof layer during construction. In addition, construction workers need to place heavy objects on the ground, carry cement yellow sand and tiles, etc., which can easily cause damage to the waterproof layer. If the damage is not repaired or not found, leakage will inevitably be caused in the future, so a protective layer should be made immediately after the waterproof acceptance.

Construction method of waterproof protective layer

Since the waterproof protective layer is so important, how should it be applied? Waterproof protective layer usually uses cement to add interface agent and then add rigid waterproof material to stir evenly. The strength of this mixture will exceed that of ordinary concrete materials after being coagulated. At the same time, the addition of a rigid waterproof material is also a waterproof barrier. This kind of waterproofing is foolproof.

In addition, the waterproof protective layer can also be covered with cement mortar. The practice of cement mortar protective layer is: after passing the water-proof test, drain the water stored on the ground, and use cement mortar to make a 1cm thick 1: 3 cement mortar protective layer on the surface of the flat coating film to avoid damage to the coating film in the later decorative construction.

In general, the role of the protective layer is to protect the waterproof layer from damage during later decorative construction. If you want to make the bathroom waterproof, this step must not be saved. Some irresponsible waterproof teams will omit this link in order to shorten the construction period and complete it as soon as possible during construction, or some construction personnel have no professional skills and fail to realize the importance of the waterproof protective layer, which will eventually lead to seepage. Leak occurs. Therefore, to make the bathroom waterproof, we must ask a professional team to regulate the construction.

In terms of waterproof construction services, Yulong Waterproof strictly implements a standardized construction system. The protective layer of cement mortar is an important part of Yulong Waterproofing standardization construction. As a professional waterproof material supplier, Yulong Waterproof actively promotes standardized construction throughout the country in recent years, standardizes the industry construction system, improves the quality of workers, and is committed to serving millions of households with quality.

Leakage after paving is very troublesome, not only troublesome to repair, but also cause unnecessary economic losses. Want to make our bathroom more secure, don’t forget to make waterproof protective layer.
