Before coating construction, the adhesion of base surface should be removed to make the base surface clean and tidy, so as to improve the adhesion between coating and base.

2) finished product protection

(1) Strengthen the awareness of finished product protection, and doodle and pollution are strictly prohibited.

(2) When there is a small area of pollution in operation, it should be cleaned up immediately and restored to its original state.

(3) Ensure product quality.

(4) Do a good job in the protection of finished products such as doors and windows, and be very careful.

XI。 Safety construction guarantee measures

There is a lot of noise when cutting and chiseling out the empty drum-this is inevitable. Our company will concentrate this part in a certain area as far as possible, and replace it with an area to educate the construction personnel to minimize noise on the premise of affecting the construction progress and quality.

Considering the normal operation during the construction period and the normal use of pedestrians and roadways around, our company takes the following safety protection measures:

1) The construction was stopped due to the rush hour and rest.

2) Because the building materials in the residential area are uniformly placed, there are special guards to avoid children's contact.

3) The residential construction site is guarded by full-time personnel, and children are not allowed to break into the construction area.

4) Establish a safety inspection system to eliminate hidden dangers of accidents and implement corrective measures.
