The decorating company accounts for 60-70% of the cost of the renovation project. Under normal circumstances, the number of house renovation costs depends on the size of the renovated area. Therefore, it is necessary to measure the renovated area of ​​the house before the renovation so that the house can be accurately calculated. The amount of material needed to reduce the waste of some non-conforming materials. The amount of consumption is multiplied by the corresponding unit price, the total cost of the material is calculated, plus the labor costs, auxiliary materials fees and the decoration company management fees, and the decorator can clearly calculate their own decoration costs. On the contrary, the amount of materials used is not strict, and may bring a lot of losses to the decoration, so whether it is all-inclusive, half-package or clear package, the amount of materials used by the decorators should be aware of.
Although each home improvement project is different and the materials involved are different, the method for calculating the amount of main materials based on the area is roughly the same. This article describes how to calculate the amount of main material used in home decoration, such as paint, tile, stone, wooden floor, and so on.
Floor tiles: There are four types of floor tiles commonly found on the market: 600mm×500mm, 400mm×400mm, and 300mm×300mm.
Recommendation: When the floor tiles are accurately accounted for, considering the cut-off losses, an additional 3% to 5% of the losses will be required for purchase.
Brick, wall, stone rough calculation method
◆ Floor area of ​​the room ÷ Area of ​​each floor tile × (1+10%) = number of bricks (in the formula, 10% refers to increased loss).
Precise calculation methods for floor tiles, wall tiles, and stone
◆ (Room length ÷ brick length) × (Room width ÷ brick width) = Number of bricks
Examples
5mm long, 4mm wide room, using 400mm × 400mm specification tile calculation method
◆ 5m ÷ 0.4mm = 12.5 blocks (take 13 blocks)
◆ 4m÷0.4mm=10 blocks
◆ 13×10 blocks = 130 bricks total
Wall tiles: There are many varieties of wall tiles. When accounting, you should first find out the position of the surface of various specifications of the magnetic discs from the construction drawings, and then calculate the area of ​​the magnetic discs at each position, and then place them everywhere. The total area of ​​various magnetic pieces can be obtained by adding together the sizes of the magnetic pieces, and finally add 3% of the loss.
Stone: Ground stone - The consumption of ground stone is roughly the same as that of tile, except that the ground mortar layer is slightly thicker. Considering the cutting loss at the time of budget usage, the handling loss is larger than the tile, and the loss should be about 1.2%. .
Wall stone - When calculating the wall stone, the accounting should be carried out separately, and calculate the total area according to various specifications. For the complex wall surface and modeling wall surface, the total area of ​​each specification should be calculated according to the unfolded area. After that, the number of plates of various specifications can be obtained by dividing them by the size of the specification, and finally, the loss amount of about 1.2% is added.
Wallpaper: When calculating the amount of wallpaper, the height of the skirting board and the top line must be subtracted. In addition, the door and window area of ​​the room should be subtracted from the number of used components. The larger the pattern of the wallpaper collage, the greater the loss, so it is about 10% more than the actual usage.
Wallpaper rough calculation method:
◆ Floor area × 3 = total area of ​​wallpaper
◆ The total area of ​​the wallpaper ÷ (0.53 × 10) = the number of wallpaper
The exact calculation method of wallpaper:
◆ Wallpaper per roll length ÷ Room actual height = number of components used
â—†The width of the room's circumference = the total number of units used
â—† Total number of using units åˆ†é‡ Number of used units = Number of wallpapers used
Composite floor: composite floor common specifications are 1200mm × 190mm, 800mm × 121mm, 121mm × 295mm
Suggestion: Many readers buy directly according to the size of the living room, but the composite wood floor often has 3%-5% of the loss in the pavement. If you use accurate calculation methods, you can not ignore this part of the amount.
Composite floor rough calculation method:
◆ Room floor area ÷ (1.2m × 0.9m) × 105% (where 5% is the amount of loss) = number of floorboards.
The exact calculation method for laminate flooring:
◆ (Room length board length) × (Room width board width) = number of floorboards
Examples
The calculation method for the usage of a room with a length of 4m and a width of 5m is as follows
◆ Room length 5m÷1.2m=4.17 (block) take 5 pieces
◆ Room width 4m ÷ 0.19m = 21.05 (block) take 21 pieces
◆ The total amount of board: 5 × 21 blocks = 105 blocks
Solid wood floor: common specifications 900mm×90mm, 750mm×90mm, 600mm×90mm
Recommendation: Because solid wood flooring is more vulnerable to damage, accidental damage is inevitable during the paving process. Therefore, a 3%-8% loss should be reserved on the basis of accurate calculations when purchasing.
The rough wood floor calculation method:
◆ The floor area of ​​the room, each floor area × 108% (of which 8% is the amount of loss) = the number of floorboards.
The exact calculation method for solid wood flooring:
◆ (Room length board length) × (Room width board width) = number of floorboards
For example:
For 4m long and 5m wide rooms, the calculation method for 750mm×90mm×18mm is as follows:
◆ Room length 5m ÷ 0.75m = 6.67 (block) take 7 blocks
◆ Room width 4m ÷ 0.09m = 44.44 (block) take 45 pieces
◆ The total amount of board: 7 × 45 blocks = 105 blocks
Curtains: Normal curtains are mostly flat curtains. Before calculating curtain materials, first determine the size of finished curtains according to the specifications of the windows. Finished curtains should cover the left and right sides of the window frame by 0.15m, and double folds. When installing, the curtains should be 15-20mm from the ground.
Curtain calculation method:
â—†(curtain +0.15*2)=finished curtain width
◆ Finished curtain width ÷ Width × curtain height = curtain fabric
For example:
Take the cloth width 1.50m as an example
◆Need to buy curtain fabric: 3.70m÷1.50m×2.75m=6.78m
Assuming the window specifications: 1.55m wide and 1.90m high, the exact calculation method is as follows:
â—† Finished curtain width = (1.55m + 0.15m x 2) x 2 = 3.70m
â—†The curtain height = 0.15m + 1.90m + 0.50m + 0.20m (Burma side) = 2.75m
8, paint latex paint: The basic packaging of the paint he is 5 liters and 15 liters of two specifications, commonly used in the family have 5 liters capacity, for example, 5 liters theoretical brushing area of ​​two times 35 square meters.
Suggestion: The above is only the theoretical amount of brushing. If the brushing effect is not good, you need to make up the brush. Therefore, the above amount is only the minimum amount of brushing. In fact, there should be room for actuarial quantity when purchasing.
The rough calculation method for paint latex paint:
◆ Ground area × 2.5÷35 = bucket number
The rough calculation method for paint latex paint:
◆ (room length + room width) × 2 × room height = wall area (including door and window area)
Room length × room width = ceiling area
◆(wall area + ceiling area - door/window area) ÷35= bucket number
For example:
For a room with a length of 5m, a width of 4m, and a height of 2.7m, for example, the calculation method for the indoor wall and ceiling coating area:
◆ Wall area: (5m+4m)×2×2.7m=48.6
