Before plastering the ceiling, the base should be cleaned and wetted in advance. If the surface is too smooth, it should be scraped and leveled with plain cement slurry.

Before plastering, a horizontal line should pop up on the surrounding wall. Based on the horizontal line on the wall, it should be leveled and rounded around the ceiling first. ?

2, interior wall plastering construction method:

First, the house should be laid out, and a small room can be used as the baseline, one square foot. For example, when the room area is large, the reticle should be popped up on the ground first as the wall plastering line. When it is about 10cm away from the wall, it should be hung straight with a line and a vertical line will pop up on the wall. The floor line (reticle) and the flatness of the wall in the room should be reflected inward, and the corner plastering line will pop up. ?

When there is no corner protector for indoor wall, cylindrical external angle and door opening external angle, 1:2 cement mortar can generally be used to wipe out the corner protector, the height of the corner protector is not less than 2.0m, and the width of the corner edge is not less than 50mm. Its practice is: plaster according to the thickness of ash cake, and after the mortar is slightly dry, smooth the small fillet with corner trimmer and cement mortar. ?

Reasonable arrangement of skilled and responsible technical workers to hang up the thread and make ash cakes before plastering. After the ash cake is slightly dry, it can be washed according to the ash cake, horizontally or vertically. After the screed reaches a certain strength, sprinkle water to wet the wall, then plaster hard between the two tendons, and smooth the surface with a wooden washboard. ?

When the strength of bottom ash reaches about 60~70%, apply medium ash, and the thickness of medium ash is slightly higher than that of screed. Use a trowel to level off according to the screed height, then use a wooden trowel to flatten the surface to make it smooth and dense, and use an inner trowel to straighten the internal angle. Do indoor square corners, and finally carry out surface plastering construction. ?

3, ceiling plastering construction method?

Before plastering the ceiling, the base should be cleaned and wetted in advance. If the surface is too smooth, it should be scraped and leveled with plain cement slurry.

Before plastering, a horizontal line should pop up on the surrounding wall. Based on the horizontal line on the wall, it should be leveled and rounded around the ceiling first. ?

The ceiling surface should be smooth and compact, and there should be no lines, bubbles and unequal joints. The internal angle of ceiling and wall should be in a straight line in Cheng Yi. ?

If the stay time is too long and the bottom layer is too dry, it should be wetted with water, and the ash thickness of the surface layer should be controlled within 5 mm?

4, the construction method of external wall plastering?

Before plastering the external wall, clean up the mortar, dirt, concrete blocks and other sundries at the grass-roots level. Block your feet, hands and eyes, and water the wall.

Starting from the top floor, hang the through line with a big line, find the big corner window vertically and hang the through line. Find the center line and horizontal line to ensure that the window is consistent from top to bottom, horizontal and vertical, and the external angle is square. ?

The grass-roots treatment should be meticulous, and when there is a depression at the grass-roots level, it should be filled with mortar in layers. ?

Before plastering, brush 107 colloidal cement slurry::, and the mixing ratio is 107 colloid: water = 1:4. When plastering, the thickness shall be controlled based on the screed, and the bottom ash shall be wiped hard to make the mortar squeeze into the mortar joint and make it firmly bonded. The surface should be leveled and rubbed flat, and the flatness, verticality and founder of the angle of Yin and Yang should be checked in time, and the problems should be repaired in time.

Extended data:

Building plastering includes:

Plastering engineering is divided into internal plastering and external plastering. Usually, the plastering of all parts of the room is called internal plastering, such as floor, ceiling, dado, skirting line and internal stairs. The plastering of outdoor parts is called external plastering, such as external walls, awnings, balconies and roofs.

Internal plastering is mainly to protect the wall, improve indoor sanitary conditions, enhance light reflection and beautify the environment; In the room prone to moisture or acid and alkali corrosion, it mainly plays the role of protecting walls, ceilings and floors.

External plastering is mainly to protect the wall from wind, rain and snow erosion, improve the ability of moisture-proof, wind-proof and thermal insulation of the wall, and improve the durability of the wall. It is also one of the measures for artistic treatment of various building surfaces.
