General plastering engineering technical briefing

1. Preparation before general plastering engineering operations

1.1 The main structural sub-projects of the plastering parts have been completed by the relevant units (Such as construction, design, supervision, construction units, etc. must agree to accept and sign for approval). The pipelines that need to be buried have been installed and passed the inspection. The scaffolding used for plastering should be set up first. The scaffolding should be 200-250mm away from the wall. The scaffolding boards should be set up to prevent dust from falling on the ground and causing waste. Chill out the protruding parts of the surface of concrete walls, etc., chisel honeycombs, pitted surfaces, exposed reinforcements, loose parts, etc. to the solid point, fill them up in layers with 1:3 cement mortar, and remove exposed steel bar heads and lead wire heads.

1.2 For brick walls, they should be watered and soaked the day before plastering.

1.3 After the construction of the wire pipes buried in the wall is completed, use 1:3 cement mortar to fill the grooves. After filling to the height of the wall, hang a 22# steel wire reinforcement mesh there. The steel wire reinforcement mesh should be Extend 100mm into the wall along both sides of the cable trough.

2. General plastering engineering material requirements

2.1 Cement: ordinary Portland cement or slag Portland cement of grade 32.5 and above.

2.2 Sand: Medium sand with an average particle size of 0.35-5mm.

3. General plastering engineering construction equipment

Mortar mixer, scale, sieve with 5mm aperture, narrow trolley, iron plate, shovel, flat shovel, ash spoon, watering can, ash tray , wooden trowel, iron trowel, female (yang) angle trowel, plastic trowel, large bar, medium bar, 2m ruler board, line support board, eight-figure ruler, 5~7mm thick square ruler, soft scraper Ruler, square ruler, iron level, etc.
