Nothing complicatedcalculating the amount of wallpaper on the room is not.Let us consider in detail how this can be done.
expect wall surface
One of the requirements that must be taken into account for the correct selection of wallpaper - is to have the exact dimensions of the room, that is, its height, width and length, and the number and dimensionsdoor and window openings.Of course, it is important to know the parameters and wallpaper, but more on that later.First, you must calculate the total area of the walls.It uses a proven formula that looks like this:
- SO = 2AH + 2BH , where:
- SO - the total area of the walls in the room,
- A and B - the length and width of the room;
- H - its height from the floor to the ceiling;
- 2 - number of parallel walls.
If the wall instead of four, for example, five or more, and their length varies (one wall cut angle the next room, or is it a balcony in a luxury high-rise buildings in Moscow city center, which is made in the form of a pentagon), then the formulaIt will look like this:
SO = AH + BH + CH + DH , where:
- A - Lengththe first wall;
- B - the length of the second wall;
- C - third and D - the fourth wall.
In this case the height of the room remains the same, but the length of the walls are different, so multiply by 2 is no longer necessary.If the height of the walls is different, for example, because of the emergence stage, then you must also specify a different height.
Do not forget about openings
area of windows and doors is calculated even easier - to get the data you need to multiply the width of the window or door at his height.We consider how many windows and doors (including entrance).Calculates the square, we summarize them all, and the result is subtracted from the total area of the room.We get the value net of places where the wallpaper will not stick.
measurement results best record in centimeters and not round, so it will be more accurate.Then, when converted, they can be converted into meters, that is, 3460 will be equal to 3.46 cm m.
Decorating the walls under the wallpaper
Another important point, which will allow (or, in the absence of this factor, will not) pokleit wallpaper right - is how smooth the wall.So, in order to find out, you will need a rule, conventional or laser level.With these tools, you can easily determine whether all is well with the surface of the walls, or you need something to fix.Therefore, when calculating the wallpaper would be superfluous to provide funds for the plaster and putty.
Calculate the amount of coating material is also easy.It is sufficient to find in the table data, a number of fillings will go to 100 m2, and then calculate how much, for example, need to room somewhere 30-40 squares.
Determine the number of rolls
rolls of wallpaper
How now to calculate how many rolls you will need a room, because the seller is unlikely to help our data about the area of the wall.At best, you will be given an approximation.The result of this negligent approach - wallpaper may not be enough, or will be over.It is understood that perfectly calculate it does not, but still, more accurate data possible.
Imagine, for simplicity, the following example: the room has a length of 6 meters, a width of 3 m, ceiling height 3 m, too. Roll, who have noticed in the shop even earlier, has a width of 60 cm (0.6 m) and its length30 meters. The length of such coils fit wall (0,6 × 3) × 10.That is, 0,6 × 10 = 6 m, that is, the length of our room, and 3 - height.Now we find that on one wall without openings leave 18 m. Then, on the two walls, respectively, 36 m. The second wall is calculated similarly, causing it to be 18 m pokleit wallpaper.So often it would be 54 meters, which is almost 2 rolls of wallpaper.Now we can take away window and door openings.Let them be one, 1,5 × 1 window and door 2 × 0,7 m. Overall - a bit, but one of the roll is still not enough.
Next, apply the following principles - the store will not sell half a roll of any one vendor, as he did not ask.Hence, it is necessary to carry out a purchase, our rounding the resulting value in a big way - 2 pieces.Wallpaper on the ceiling, calculated on the same principle.
If the wallpaper are glued together with something, such as tiles, while the area that it takes, must be subtracted from the total area of the whole room.
unlikely that someone will be glued to the wall piece of wallpaper half a meter, perhaps, if he does not come in handy somewhere near or above the window sill, but the probability of a match for the pattern is very small.
required amount of glue
Adhesives, on average, calculated on the basis of 3 kg / 100 m2.Therefore, if the wall surface of the room, in general, is, for example, 30 m2, the adhesive need to buy 100/30, i.e. 1.3 kg.
hem wallpaper postelennuyu floor (laminate, parquet or other) fits wooden or plastic moldings, which does not allow the wallpaper to come off the bottom.Top fixing glued to their border with ornaments or moldings (moldings), which not only serve as a preservation of the wallpaper, but also give the room after repair unusual appearance.
In this video course are presented and described in terms of the calculation of the required number of rolls.
