Do not know where to find chores - start plastering the walls of the house. This lesson requires accuracy in the approach to calculations and the correct measurement of the surface under the finish. Therefore, before you start leveling and decorating the walls, figure out how to calculate the square of the walls for plaster. Knowing the vertical surface area under the finish will help to avoid unnecessary waste on consumables.
Literacy of calculations - the secret to quality repairs
Having made the correct calculation of walls for plastering, consider that half the battle is done. The main question that is asked during construction: how to calculate the quadrature of the walls in the room, taking into account the window and door openings?
If the construction team plaster the walls, then the calculations of the master will be carried out independently. Even without doing this, but planning the construction, it is better to get knowledge on how to calculate the area of walls. As a result, you will know the exact quadrature for self-finishing and be able to verify the correctness of the data of the working masters.
What is useful during the calculation
The quadrature is calculated using a tool such as:
- construction tape (from 5 m);
- pen or pencil;
- calculator;
- building level;
- stepladder or stool;
- notepad or sheet of paper for notes and formulas.
Prepare the tools you need to measure the walls and get ready to get started.
Where to start the calculation
Before calculating the quadrature of the walls, move the furniture to move freely. This is an important aspect, since the initial indicators obtained from the calculation of measurements will reflect the volume of the room, the square of the floor and ceiling coverings.
How to measure surface areas
To measure the surface, draw a straight line 4-5 cm above the level of the plinth, using a level or other level bar to check.
Then, putting the tape measure on the dash, measure the length of the walls and write the indicator on paper.
In the next step, get ready to calculate the height of the walls from the ceiling to the floor, following the same pattern. Having received the necessary values, it remains to figure out how to calculate the quadrature of the walls according to the formula.
Calculation Rules
To obtain the area of the walls in a rectangular room, the width is multiplied by the length. Let's look at an example.
The length of the wall is 6 m, the width is 4. S = 6 * 4 = 24 m 2 . Similarly calculate the area of other surfaces and add up. The length of two walls in a rectangular room is 8 m, the other two - 6 m. As a result of folding: 8 * 2 = 16, 6 * 2 = 12, 16 + 12 = 28 m - the sum of the lengths of the surfaces of the walls of the room. S = 28 * 4 = 112 m 2 . This is the area of all the walls in the room
Calculation of the area of window and doorways
When figuring out how to calculate the quadrature of the walls correctly, it is worth considering that window and door openings are also measured to calculate the surface to be treated. Measurements are taken only from the slopes of the openings. This stage is important when calculating the surface area to be trimmed. So, the area of a rectangular window with a width of 1 and a height of 1.2 m is 1.2 m 2 (1.00 * 1.20 = 1.2). If the room has more than one window, then their dimensions are measured separately. And the areas are summed up to get the final result.
Similarly measure doorways. It is important to take parameters not on the canvas, but on the slopes. As a result of measurements, it becomes clear that the area of the window slopes is 1.20 m 2 , and the doorway, for example, is 4.80 m 2 . Further, the dimensions add up to one number: 1.20 + 4.80 = 6 m 2 , and are subtracted from the room area: 112 - 6 = 106 m 2 .
Now you know how to calculate the quadrature of the walls and which formulas to use to get the exact final value. Such knowledge is useful and practical. After all, the owner of an apartment or house will not have to spend extra money on finishing materials, which will ultimately remain in excess. Knowing how much coverage is needed, you can drastically reduce the amount of waste and save on the repair budget by spending money on arranging a room’s interior.
