How much does it cost to build a 1 m2 wall? The contractor is interested in finding both units and workers to ensure the appropriate cost for the investor but still ensure the committed progress and quality. In general, the unit cost of painting brick walls, the unit labor cost can change is 55,000 VND/m2, the unit cost of ceiling painting labor is about 85,000 VND/m2, the unit cost of decorative wall painting depends on the specifics according to the construction drawing. .
The order and technical requirements when painting and plastering the walls, plastering the ceiling, beams first, then the walls and columns behind. Plaster according to the thickness of the marker. Apply several test spots to check structural adhesion. When stopping plastering, it is necessary to create a circuit to stop the broken shape, not to straighten, and store the plaster at an angle. Use cement mortar grade 75.
The plaster layer adheres firmly to the surface of the grout-type structures and the thickness of the plaster layer must meet the requirements according to the surface of the mortar layer must be smooth and flat. Edges should only be level with the vertical hand
Sand leveling materials unit price 165,000 VND/m3
Yellow concrete material 380,000 VND/m3
Building sand materials 345,000 VND/m3
Washed concrete sand type 2: 365,000 VND/m3
Special sand for molding only: 600,000 VND/m3
Materials are guaranteed in quality and quantity for the right screed. For bare walls after plastering, the plane is checked by aluminum ruler, in the direction. The surface of the wall after plastering should not have cracks, roughness, footfall or flowing grout. Pay attention to plastering under window sills, door ledges, wall skirts, oven legs, stoves, and other easy-to-miss places.
The edges of the door ledge columns must be straight and sharp, the right angles must be checked with a protractor. Window sill ledges should be aligned with each other. The surface on the window sill must have a slope according to the design and the plaster layer is at least 10mm deep under the window frame.
Follow safety rules when working on scaffolding and at height. The junction between the brick and the wood needs to be roughened to the surface of the wood before plastering. When plastering is complete, it is necessary to carefully cover up to avoid the impact of weather, and collision due to accidental impact.
In order to accurately calculate the cost of 1m2, it is necessary to clearly determine the cost of materials, labor hire and completion schedule to quote a relative price in this case.

To determine the number of bricks to build a wall, we can apply the following formula:
A = (length+width) * 2
B= A * height of wall
After calculating B, we subtract the vertical doors and windows within the wall (if not, do not subtract). From there, it will determine the number of bricks needed to build 1m2 of the wall. Depending on the type of brick, the size, the type of wall and the thickness of the wall, there will be a different amount of brick waste.
To build 1m2 of wall 10 with dimensions of 80x80x180 mm requires an average of 55 bricks.
To build 1m2 of 20 walls with dimensions of 80x80x180 mm requires an average of 110 bricks.
To be able to calculate accurately, we need to check the norm of building materials that need to be used to build 1m2 of wall according to the contractor's plan. Then multiply the area to be built to get the overall volume of materials.
