    Key tips: 1

    Preparation before construction The quality of coating engineering decoration largely depends on the quality of coating product construction

    A good coating product must be supported by the standard construction of coating industry in order to get a good engineering quality

    If the coating construction is improper or the relevant precautions are not taken seriously, it is easy to cause quality accidents

    If the project is reworked, it will be very difficult, so coating construction Preparations must be made before

    ① Check the construction drawings and determine the construction parts to prevent the shutdown or rework due to problems

    ② Check the flatness and strength of the plastering layer Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively

    The feature of the breathing wall is obvious

    When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity

    It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively

    The feature of the wall that can breathe is obvious

    When the indoor air is relatively dry, the wall of diatom mud will absorb the water Home of coatings: 1、 The quality of preparation for coating engineering decoration before construction largely depends on the quality of coating product construction

    A good coating product must be supported by the standard construction of coating industry to get good engineering quality

    If the coating construction is improper or the relevant precautions are not paid due attention, it is easy to cause quality accidents

    If the project is reworked, it will be very expensive Therefore, preparations must be made before coating construction

    ① Check the construction drawings and determine the construction parts to prevent the shutdown or rework due to problems

    ② Check whether the evenness, strength and other indexes of the plastering layer meet the construction requirements

    If it is a construction problem of the civil engineering party, it shall be put forward to the supervision party for rework

    ③ Confirm the type, color and quantity of paint purchased to avoid problems after coating

    ④ Be familiar with the construction process of coating products, and select the coating tools that meet the construction requirements

    2、 The requirements of the base surface and the treatment of the building base surface have a significant impact on the quality of the project, so it is necessary to ensure that the base surface meets the construction requirements

    ① Cleaning: all kinds of sundries attached to the base course, such as dust, grease, rust, cement white matter, etc., shall be thoroughly removed by means of high-pressure water washing, grinding of machinery and tools, chemical cleaning, etc

    ② Leveling: in order to ensure the decoration effect after coating, the wall surface leveling shall meet the national high-level plastering standard, and the damage, cave, crack, hollowing and shelling of the base course shall be repaired in advance, the putty shall be inlaid flat, polished smooth, the internal and external corner lines shall be vertical, and the base course shall be level

    ③ Drying: the high moisture content of the base course will seriously affect the quality of the project coating

    The moisture content of the base course during the coating construction shall be less than 10%

    At the same time, ensure that the moisture content of each repair place and the main wall is the same before the construction

    Generally, the newly-built wall needs to be cured for 3-4 weeks before putty application and coating construction

    ④ Acidity and alkalinity: excessive alkalinity of the base course will seriously affect the performance of the coating, and the pH value of the base course shall be less than 10 during the coating construction

    Generally, the newly-built wall needs to be maintained for 3-4 weeks, and the pH value can meet the construction requirements

    ⑤ Firm: the surface of the base course shall have certain strength and rigidity, which shall be higher than the brushing material

    The surface of the base, aerated concrete, which is crisp, silt, or powdered, must be treated with additional strength

    Generally, it should be thoroughly removed and then repaired with emulsion mortar

    3、 Construction process ① according to the specific coating effect, brush, roll, spray and other methods can be used for construction, generally roll coating can be used

    ② For the coating system (according to the roll coating method), the base putty shall be added for leveling, and then the upper primer shall be applied

    Use the Liangdi sealing primer and roll coating once

    The coating shall be uniform without omission

    After the construction, the interval between the next construction and the next construction shall not be less than 4 hours (outdoor, 25 ℃), relief putty or other relief putty can be selected, and the mortar gun can be used to spray the putty on the base surface

    The size of the nozzle used depends on the size of relief required for decoration

    After the putty particles are basically dry, the surface shall be moistened with smooth rubber roller or rolled with 200 solvent (if necessary for the project Rolling is not required)

    It is required that the distribution density is moderate and basically uniform

    After construction, the construction interval with the next process shall not be less than 24 hours (outdoor, 25 ℃)

    Interior paint shall be used for surface coating

    Generally, 5-10% water shall be added to dilute (or not dilute), and the construction shall be carried out after full mixing, and one roll coating is enough

    The coating shall be uniform without sagging or missing
