How to write the construction plan for exterior wall decoration?

1. Base treatment: As this project is an old building reconstruction, the quality of the base is poor, so it is necessary to increase labor consumption and technology, and manually remove the original peeling paint to ensure the cleanliness of the base.

2. Technological process: basic treatment → repair putty → scrape putty → brush emulsion thin paint once → brush exterior waterproof latex paint twice.

3. Grass-roots treatment: firstly, peeling, looseness, bulging, etc. on grass-roots such as walls are removed and chiseled, and impurities such as dust, dirt, splash and mortar flow marks remaining on the surface of grass-roots are removed and swept away.

4. Repair putty: Level pits, depressions, cracks, etc. with external wall mortar and flexible putty. Knocked on the wall and other grassroots units. After drying, smooth the protrusions with sandpaper and sweep away the floating dust.

5. Blow putty: The frequency of blow putty can be determined according to the flatness of the base or wall.

6. Emulsion Bo Tu once: When painting the wall in sequence, it should go up first and then down. Wipe the wall clean first. Emulsion Bo Tu is generally coated with a roller brush. The emulsion thin coating should be evenly mixed before use and diluted with water to prevent the first coating.

7. First coat: fully mix before use. If it is not very thick, it is not appropriate to add water or add as little water as possible to prevent the bottom from showing. After the paint film is dry, use fine sandpaper to polish off the small bumps and brush strokes on the wall, and then clean them up after grinding.

8. Finish painting for the second time: the operation requirements are the same as those for the first time. Because the latex film dries faster, it should be operated continuously and quickly. When you brush, you should start from one end and gradually brush to the other. Attention should be paid to the connection of the upper and lower brushes to avoid the joint being treated after drying.
