    Observe the stairwells, elevators, or other public walls of your house for signs of mildew, chalking, or shedding.



    Shandong Weihai Quality Supervision Station requires that from October 1, 2016, stairwells and corridors of new residential construction projects need to be scraped on the walls of public parts on the ground, and stairwells and elevators of new public construction projects need to be scraped.



    The purpose is clear: to prevent the wall from falling off and damage the indoor public parts of the building, and to ensure the durability and visual quality of the wall.



    This time, the Quality Supervision Bureau requested the implementation of the "Water-resistant Putty on Walls" policy to be implemented on the National Day this year, and analyze the reasons for it.

    Ordinary putty is afraid of water, it dissolves when it meets water, and its water resistance is extremely poor.



    After the last typhoon "Nibert", a resident of Bandong, Fujian, whose home was destroyed and soaked in a century-old house, was destroyed by floods.


    2.
    Good durability, no need to eradicate the second decoration




    Ordinary putty has poor water resistance, so it must be removed and cleaned together with the original paint when re-decorating in the future, and then the putty should be scraped again.
    Not only does it increase decoration costs (material costs, labor costs), the removed waste also causes a waste of resources, is difficult to recycle, and will pollute the environment.
    Water-resistant putty is done once and for all.
    After a few years of renovation, you don’t need to shovel the putty layer off for two, three or more times.
    After polishing the surface and partial repair, you can proceed to the next process, which saves time and effort and protects the wall.

    Save the amount of paint




    The traditional putty has strong water absorption.
    When the latex paint is brushed for the first time, the coating film has not been fully leveled, and the water in the paint is absorbed by the bottom putty.
    Therefore, the latex paint is applied on the surface of the traditional putty because it absorbs water quickly.
    , Poor leveling.
    As a result, the coating film after painting the finished product is not smooth and delicate enough, and more latex paint is used.
    The unique whiteness and density of water-resistant putty make it possible to save 25-30% of the amount of paint used per unit area of ​​paint compared to walls with ordinary putty.

    High bonding strength




    The JG/T298-2010 "Building Indoor Putty" standard clearly stipulates the strength of the putty.
    The standard state bond strength of ordinary putty is greater than 0.
    25MPa, and there is no requirement for the strength after immersion, while the water-resistant putty requires the standard state bond strength Reaching 0.
    50MPa, the bond strength after immersion in water is greater than 0.
    30MPa.
    It can be seen from the standard that the strength of water-resistant putty is higher than that of ordinary interior wall putty, so the use of water-resistant putty is not easy to cause hollowing and falling off.

    Using Dajiang Waterproof Putty, you don't need to add any ingredients during construction, just add water, and you don't need to spend extra money to buy white latex, glue and other ingredients.
    The wall decoration effect and service life after making water-resistant putty are far beyond the reach of ordinary putty.
    And from the comprehensive calculation of the amount of paint and the cost and construction cost of the putty during the second decoration, the cost of using water-resistant putty is lower than that of ordinary putty.

    Comparison of environmental protection between water-resistant putty and traditional putty

    Traditional putty not only has extremely poor water resistance (it melts immediately in water), and the glue used to reconcile the putty contains free "formaldehyde".
    "Formaldehyde" is a recognized carcinogen, and its volatilization cycle is several years.
    The wall area of ​​home decoration accounts for about 70% of the space of the whole house.
    If the wall is filled with 2-3 times of traditional putty, a lot of glue needs to be used.
    A household's consumption ranges from more than ten barrels to as many as tens of barrels.
    After the construction is completed, a certain amount of free "formaldehyde" will be permeated in the residential air, and long-term life in it will inevitably bring health hazards.

    In places like Shandong, Jiangsu, Zhejiang, Shanghai, Guangdong and other eastern and southeast coastal areas, especially typhoon-prone areas, there is plenty of rain, and the overall humidity is high throughout the year.
    In the humid season, the walls are prone to mold.
    Moldy walls not only affect the beauty, but also troublesome to deal with stubborn diseases such as cracking and falling off, and bring many inconveniences to life and living environment.
    Public building walls have begun to use water-resistant putty, which also illustrates the importance of water-resistant putty to ensure the quality of wall coating.
