Sand blasting construction plan for the kindergarten's outer wall

Answer 1

The following is an example of a kindergarten's exterior wall sandblasting construction plan:

##1. Construction preparation
1. ** Material preparation **
- According to the ratio of powder: sand = 1:(1.5 - 2.0), the sandblasting material was prepared, and the special sandblasting glue was added to fully stir.
- Prepare real stone paint (if real stone paint is used for sandblasting on the outer wall) and other auxiliary materials, such as primer.
2. ** Tool preparation **
- Prepare an air conditioner and try to maintain the pressure at 8Pa during construction.
- Prepare the spray gun and ensure that the spray gun is in good condition.
3. ** Wall base layer treatment **
- Clean the base layer of the wall, tidy up the loose soil, remove the dust on the wall, repair the holes, and ensure that the wall is flat.
- Moistening the processed wall to enhance the sandblasting ability and prevent cracking.

##2. Construction Flow
1. ** After the basic layer is processed **
- Coat the base paint evenly.
2. ** Sand blasting construction **
- The spray gun was kept at a vertical distance from the wall. The spraying distance was controlled between 30 - 50 cm, and the spraying was carried out from top to bottom.
- It formed a blasting height of 1 - 3mm, and the diameter of the bottom was about 2mm, so that the spraying effect was evenly covered in dots and nets.
3. ** Follow-up maintenance and improvement **
- After the completion of the construction, spray water on the wall for maintenance. Spray water 3 - 5 times a day. After reaching the strength, you can carry out subsequent operations (such as plaster construction, etc.).
- If there are requirements such as color separation and edge grinding, it should be carried out according to the corresponding process. For example, the edge grinding should be uniform and coated with edge grinding paint.

##3. Quality Control
1. Strictly follow the construction process to ensure the quality of every step of the construction.
2. During the construction process, accept the on-site supervision of Party A (the kindergarten or the relevant responsible party) and the supervision department to ensure that the quality of the project meets the predetermined standards and the colors are consistent (painting and construction according to the renderings or the agreement of both parties).

##IV. Safe and Civilized Construction
1. Construction personnel should take safety precautions, such as wearing safety helmets.
2. Civilized construction, put an end to all kinds of disciplinary and illegal phenomena, and avoid the construction process from interfering with the normal order of the kindergarten.
