    During the construction of the waterproof coating, some waterproof masters had some bad habits or did not understand the specifications, and the operation did not follow the construction plan, which greatly reduced the waterproof effect.
    Therefore, in order to improve the quality of waterproofing projects, remember not to step on these 10 minefields of waterproof coatings.

    01.


    It only needs to be brushed 3 times for waterproofing, the thickness does not matter

    It is not only the number of passes and cross-brushing direction requirements that apply to waterproof coatings, but the thickness of each pass is also very important .

    Because it is too thin, it cannot meet the waterproof requirements.

    Specification: The thickness of the ground waterproof layer coating film should meet a certain thickness requirement.

    02.


    As long as the thickness is enough, it doesn't matter if you brush it a few times

    The waterproof coating must be brushed again and again according to the process requirements, and the last time is dry and then brushed again, and the thickness of each part should be uniform.
    Don't just pour the waterproof paint on the ground and brush it casually in order to save trouble.
    The thickness of each part is different, and the degree of dryness is different, so that waterproofing is nothing.

    03.


    Brush waterproof coating directly on the napped layer

    There are hidden dangers in brushing like this.
    Even if the burr tip is coated with waterproof coating, it is the weakest place; many families do not shovel the original wall burr layer before applying waterproofing, and directly apply waterproofing on the burr.
    If the burr is broken, that location is a small hole.
    Therefore, in the napped layer for waterproofing, the burrs must be leveled first, and it is better not to pierce the hands.
    If there is an empty drum in the napped layer, shovel the hollow part first.

    04.


    After brushing the waterproof, just do a closed water experiment

    If the closed water test is qualified, the ground should be covered with a protective layer.


    05.


    If this operation is to prevent the ground waterproof layer from being damaged, it can be done.


    06.


    Don't be afraid of trouble if there is any leakage.


    07.


    If the base layer is hollow, sandy or cracked, first treat the base layer and make it firm.


    08.


    It is recommended to lay the newly made water pipes and heating pipes on top of the waterproof layer, so that even if there is leakage, it will not hurt the neighbors downstairs first.


    09.


    It is best to clean up floating dust, ash spots, and pits.


    10.


    Rounding the yin and yang corners is an important step to avoid hidden dangers of waterproofing, because the sharper the edges and corners, the weaker the waterproofing and the more likely to cause problems.
    Generally speaking, waterproof solutions have requirements for the treatment of the yin and yang corners.
