4. The exterior doors and windows have been installed, and the arched gantry used for exterior wall decoration has been adjusted, and it is qualified before each use.

5. The base surface has been cleaned with iron oxide.

6. Cut the V-shaped groove on the wall with a marble machine, and apply polymer anti-crack mortar on the surface of alkali-resistant glass fiber grid cloth. After reaching a certain strength, put a layer of 20cm wide polyester cloth on the spot for processing, and report it to the project department for acceptance.

7, familiar with drawings, distinguish the varieties and colors of paint, accomplish know fairly well.

8. Make a good sample before large-scale construction, and organize classes only after Party A, supervision, project technology, quality inspection and engineering personnel have passed the acceptance.

Organize large-scale construction according to the model method, and make serious disclosure to the construction team. Fourth, the operation process

1. process flow: priming treatment (inspection and application) → brushing sealing primer (inspection and application) → fully scraping elastic putty once or twice (inspection and application) → framing by elastic lines, bonding textured paper → leveling by spraying aggregate (inspection and application) → preparing paint → brushing the first topcoat → brushing the second topcoat (inspection and application).

2. Grass-roots treatment: remove dust, dirt, splash and mortar marks on the plastering surface of concrete or cement slurry and the surface of cement putty. After the external wall is repaired, sand it with sandpaper. 3. The basic acceptance criteria before construction are as follows:

1 wall surface: the surface is flat, clean, smooth, straight and clear, and the water content is not ○.

More than 8%, especially around the external wall, Yin and Yang Angle, doors and windows hole and other key parts to strictly control the quality.

2 Angle of Yin and Yang: Straight and square, with no corner. zero

Windows, holes and slots: square, neat and smooth, with straight yin and yang angles. zero

4. Grid lines: uniform width, smooth seams, horizontal, vertical and smooth. zero

5 allowable deviation items at the grass-roots level are shown in the following table:

○4. Brush the sealing primer: 1 Tools used: wool roller. zero

2. Method: Brush on the wall with roller primer. zero

3 requirements: uniform brush without leakage. zero

4 easy quality problems: if the brush is uneven or missed when rolling, it contains anti-alkali, which leads to the later surface layer.

Make the topcoat appear yellow and inconsistent in color.

5. Elastic line, frame joint and adhesive tape: according to the requirements of design drawings, hang vertically, find rules, set square and elastic frame line. This work must be well controlled in strict accordance with the label, to ensure the enclosure of the building, and the exterior wall coating project should be carried out in sections, with the dividing line being the frame joint, the external angle of the wall or the vertical angle of the exterior wall.

Construction joints and joints must be straight, smooth and even in thickness. , with 20mm wide masking tape according to play good line frame seam.

6. Coating preparation: mixing diluents according to a certain proportion, and no solid matter is needed. Thin consistency is moderate, and it is convenient to use after mixing.

7. The exterior wall coating of this project has many colors and complicated parts. There are many concave and convex parts in the corner of Yin and Yang, and the colors of exterior wall coatings are white, dark yellow, brown, dark gray, dark green and so on. According to the different construction sites, the exterior wall is painted flat and sprayed, so the design drawings must be carefully reviewed before construction, and the colors and varieties of the exterior wall coating construction methods are well known. The paint colors and practices of each part are as follows (the specific colors and practices of each part of the external wall of each building are as follows)

1 The ridge line of roof parapet, upper beam of sloping tile roof, drip surface of tile roof, waist line and vertical line shall be painted gray.

Paint, the back of hall, balcony and horsehead wall shall be painted with gray paint (Tsunami 6580-2), drip line shall be painted with gray paint, and hanging lotus shall be painted with brown paint (agate111).

3. The top plates of all flaps and windows should be painted with white paint, and the lines below the tiles of the horse head wall should be painted with white paint.

21-Building 27 (refer to Building 28):

1 The back beam of the horse head wall and the inclined tile roof beam shall be painted with gray paint.

2. Under the tile of the horse head wall, turn the board upside down and paint the lines on the exterior wall of the patio with white paint.

3 hang lotus flowers, and the frame is painted brown.

8. The specific operation process requirements are as follows:

1 coating (window and door openings, internal corners, balconies, gaps between air conditioning board railings and walls, and inaccessible corners)

This method is used in other places): the brushing direction should be consistent with the stroke length, if it is left at the frame joint. If the paint you use dries quickly, brush it often with a short brush. Generally not less than two floors. The previous coating can only be applied behind the face bar. The interval between the first brushing and the second brushing is related to the temperature and humidity of the construction site, generally not less than 2 ~ 4 h.

2. Roll coating: apply a small amount of paint on the roller, and then roll back and forth gently and smoothly on the rolled wall, straight up and down.

Avoid crooked snakes and ensure that the coating thickness is consistent, about 2-3 mm, without warping, and the color and quality are consistent.

3 The colors of the selected paints are exactly the same. If the colors are different, they should be stacked separately. And design drawings ○

When the paint used is different in color, the project materials and technicians shall be informed for further treatment.

4 coating must be fully stirred before use, and its consistency or working viscosity should ensure that it does not sag when applied.

Show brush lines. In the process of use, it is also necessary to constantly stir, and do not add water or other dissolution and dilution at will. It is not a good idea to mix any kind of water-based exterior wall coating with water or pigment at will during construction.

It should be built by night light. After adding water, the coating will lose powder to the touch. Adding pigment or working at night will make the coating color uneven. If the paint is too thick or too thin, and the paint color can't meet the requirements, it should be adjusted under the guidance of the manufacturer.

6 In the process of construction, try to avoid paint pollution to doors and windows and other parts that don't need paint. If there is pollution, please

The paint must be wiped off before it is wet.

7 to prevent moisture from penetrating from the back of the coating. zero

All used machines, tools and appliances must be cleaned first, and impurities such as dust and grease must not be brought into the paint. zero

When the construction is completed or intermittent, the machines, tools and appliances should be cleaned for later use.

9 Waterborne exterior wall coatings cannot be constructed in the rain, and construction should be stopped when it is expected to rain. When the wind force is above 4, it cannot be ○.

Carry out spraying construction. The service life of the coating is within the storage period of the coating. 10 Before the paint is wet, prevent it from being polluted by rain and dust. zero

1 1 After each working procedure is completed, it shall be submitted to the engineering, technical and quality inspection personnel of the project for acceptance after passing the self-inspection by the construction team.

The construction of the next working procedure can be carried out only after the case is checked. 9, finishing

During construction, according to the principle of trimming with construction, check before and after work and every block or shelf completed. If defects such as bottom leakage, bottom seepage and depression are found, they should be repaired and treated immediately. When finished, uncover the masking paper, and then stick the masking paper on both sides of the frame seam.

Paper, with a row of brush frame seam coating. After the construction of frame joint coating is completed, remove the textured paper and trace the lines with a combination brush. Before painting the top coat, the construction surface must be cleaned and repaired and polished with cutting sandpaper. Between two adjacent layers of paint, it must be repaired with sandpaper, and then brushed with wool roller after polishing.

1 Quality assurance measures: ○

No construction is allowed in strong winds and rainy days above Grade 5 (including Grade 5). Before construction, the mortar and other rubbish on the surface of the base course.

Must be thoroughly removed, and at the same time strengthen the inspection at the grass-roots level and the treatment of fine cracks.

3. Reasonably arrange the construction sequence and prepare enough machines and tools for subsection construction; The windward side and the temperature vary greatly.

Some (such as north and west) walls shall be constructed first, and south and east walls shall be constructed later.

4. Strengthen the process control and handover, and the next working procedure can be constructed only after each working procedure is qualified. Same as 0.

Strengthen the inspection and control of incoming materials, and all unqualified materials shall not be used, and strengthen the training of operators.

V. Quality standard 1, master control project

1. 1 The variety, model and performance of exterior wall coatings meet the design requirements and must be used according to product combination. 1.2 the color and pattern of the exterior wall coating meet the design requirements.

1.3 Exterior wall coating shall be evenly coated, firmly bonded, smooth and clean, and the color separation line shall be straight and clear, and shall not be missed, thoroughly coated, rusted, peeled or dusted.

1.4 plastering layer and plastering layer and coating layer must be firmly bonded without defects such as delamination, hollowing and cracks. 2. General items:

2.2 Brush coating, spray coating, roller coating and other surface colors are uniform, the size and thickness of pattern color points are uniform, and there are no breakpoints, no curling, no large-area flower grafting, no summer-planting, no missing coating, no primer, no sagging, and the spraying is medium flower.

2.3 The width and depth of frame joints should be consistent, the joints should be smooth, and the edges should be neat, horizontal, vertical and smooth. 2.4 The slope direction of running water is correct, and drip line is straight. The width and depth of the drip tank shall not be less than 10mm, which shall be neat and consistent. Six, finished product protection measures

1. Doors, windows, walls, air conditioning panels, railings, water and electricity pipes, etc. Before construction, it will not be sprayed or rolled, and protection should be done to prevent pollution.

2, after the completion of spraying, roller coating, timely use of wood, striped cloth, etc. Protect the hole from collision and damage. 3. Dismantle and overturn shelves and scaffolding to prevent collision with walls and pollution of coatings.

4, oil workers in the construction operation, it is forbidden to step on the completed parts. Be careful not to pollute the wall with oil drum paint.

5, indoor construction is not allowed to dump garbage from the inside out, to prevent pollution spraying, roller coating surface. 6, coating before drying, prevent rain, dust pollution, blackening, etc. If it happens, handle it in time. 7. After using the daubing tool, clean it in time or soak it in the corresponding solvent to ensure that it can be used again. Seven, common quality problems and preventive measures

1, uneven color, obvious secondary joint repair: the main reasons are inaccurate mixture ratio, uneven mixing, different coating thickness, secondary repair of the bottom layer, different water content of the plastering layer and the original plastering layer, high water content of the surface layer construction and obvious secondary joint repair of the surface layer. Solution: Specially-assigned person should master the mixture ratio, unify the ingredients and measure accurately.

Designate a person to be responsible for the surface construction. It is forbidden to press the pillar of double exclusive frame on the wall to avoid secondary repair. 2. Empty drum and crack on the surface layer: The main reason is that the bottom plastering is not constructed in layers and frames as required. Prevention and control measures: divide the base according to the requirements of the map.

3. The surface construction joints are obvious: the main reason is that the construction joints are not used in the frame joints or not obvious places during the surface construction. Solution: Leave gaps in the middle of construction, which must be left in inconspicuous places such as frame joints, expansion joints or vertical line corners, and behind pipelines.

4. Good color during construction and serious pollution during delivery: the main reason is the fading of coating paint. Solution: Choose anti-ultraviolet and anti-aging inorganic pigments, strictly control the amount of water added during construction, and do not add water at will. In order to prevent surface pollution, the silicon coating should be sprayed 24 hours after the coating is completed, and the thickness is the same. Strictly control the dosage of thinner, and do not change it at will during construction. When two colors cross, one color must be fully dried before painting the other color. Eight, safety and civilized measures

1, the construction site is well ventilated. If the site construction is poor, ventilation equipment must be placed before the construction.

2. When using wire brushes, plate bolts, pneumatic and electric tools to remove rust and steel bars, please wear protective glasses to avoid eye pollution and injury.

3. Wear a respirator when painting or spraying paint harmful to human body. If it is harmful to the eyes, you need to wear closed glasses for protection.

4, besmear brushs red lead antirust paint and paint containing lead pigment, pay attention to prevent lead poisoning, wear a mask when operating.

5. Open flame is not allowed when spraying nitrocellulose paint or paint diluted by other volatile and flammable solvents. Clean and recycle paint brushes in time.

6, aerial work need to wear safety helmet and seat belt, wear flat shoes, in case of slipping.

7. When the operator feels headache, panic or nausea during the construction, he must leave the workplace immediately and go to a ventilated place to change the air. If you still feel uncomfortable, go to the health station for treatment.

8. Arch gantry scaffold is used for exterior wall coating construction. For matters needing attention, please refer to Construction Disclosure of Arch Portal Scaffold. Nine, environmental protection and health measures

1. After using the applicator, clean it in time or soak it in the corresponding solvent to ensure that it can be used again.

2. The cement residue on the wall should be cleaned up and transported to the site garbage station, and shall not be discarded at will; The cement fragments removed from the wall should also be cleaned by special personnel and transported to the garbage station.

3, waste chemical materials and their packaging, containers and contaminated land, water, oil gloves, oily cotton yarn cotton cloth,

Clean and recycle paint brushes in time.

4, paint, sealing primer is easy to pollute the environment, need to implement sealing, container management and use, try to avoid leakage, overflow and environmental pollution. Instruct the operator before operation, and pay attention to brushing evenly when using, not too much, so as not to spill on the ground and pollute the ground.
