Del floor nature floor room window wallpaper paint floor tile brick 1, floor tile usage: (Note generally different room type loss rate is different about 1-5%) per 100 meter usage = 100 / [(block length + gray seam width) × (block width + gray seam width)] × ( 1+ loss rate) For example, the retro floor tile size is 0.5×0.5M, the seam width is 0.002M, and the wear rate is 1%. The number of blocks required for 100 square meters is: 100 square meters. Usage=100/[(0.5+0.002 )×(0.5+... 1, floor tile usage: (Note generally different room type loss rate is different about 1-5%) per 100 meter usage = 100 / [(block length + gray seam width) × (block width + gray seam width)] × ( 1 + loss rate) For example, the use of retro tiles specifications for 0.5 × 0.5M, seam width of 0.002M, the loss rate of 1%, 100 square meters required Some calculation formulas for decoration costs 1. Floor tile usage: (Note that the loss rate of different rooms generally differs by about 1-5%) The usage per 100 meters = 100/[(block length + mortar width) × (block width + ash Slot width)] × (1 + loss rate) For example, the use of retro tiles specifications are 0. 1, floor tile usage: (Note: generally different room type loss rate is different about 1-5%) per 100 meter usage = 100 / [(block length + mortar width) × (block width + mortar width)] × (1 loss rate) For example, the use of retro floor tiles specifications for 0.5 × 0.5M, patch width is 0.002M, the loss rate of 1%, 100 square meters need to use the number of blocks: 100 square meters amount = 100 / [(0.5 + 0.002 ) × (0. 1, floor tile usage: (Note generally different room type loss rate is different about 1-5%) Wall Pack,Led Wall Pack Lights,Outdoor Led Wall Pack Lights,Alleyways Wall Pack Light Fuonce-Lighting , https://www.fuoncelightings.com
3, the amount of roof: the amount of roof plate = (length - length of the shield) × (width - width of the shielding), for example, the net size of the area to calculate the amount of PVC plastic ceiling. The unit price of the PVC plastic plate is 50.81 yuan per square meter, the length and width of the shield are both 0.24M, the length of the canopy is 3M, and the width is 4.5M. The dosage is as follows: the amount of the ceiling plate = (3-0.24) x (4.5-0.24). Equal to 11.76 per square meter
3, package door dosage: Package door material dosage = outside the door frame length × door frame width, for example (Figure) with composite wood door, door frame length 2.7M, width 1.5M, then its material usage is as follows: Package Door material usage = 2.7 x 1.5 = 4.05 square meters
4, wallpaper usage: wallpaper usage = (high - shielding length) × (width - shielding width) × number of walls - door area - window area (for example) wall area is calculated with a net size, shielding is 24CM, wall height 2.5 M, width 5M, door area of ​​2.8 square meters, window area of ​​3.6 square meters, the amount is as follows: Wallpaper usage = [(2.5-0.24) x (5-0.24)] x 4-2.8-3.6 is equivalent to about 36.6 square meters The above is a calculation of the amount of materials used, and the total material cost of the renovation project is calculated by multiplying each part of the decoration materials by their respective unit prices.
5, floor usage: (solid wood) vertical usage = room length / length of floor tile transverse usage = room width / width of floor tiles in case of inexhaustible, use the carry method, can not be rounded, but the longitudinal is less than half a half, more than Half a block. Total floor price = total usage × unit price floor loss = floor area - floor area floor loss rate = floor loss / housing area Note: General floor wear rate is not more than 5%
6. After determining the color variety of the wall-mounting material usage wall-mounting material, the size of the material can be reasonably calculated based on the size of the living room. Considering the possible loss during construction, it can be purchased with about 5% more than the actual amount. There are two methods for calculating wall materials: 1. Calculate by formula, multiply the area of ​​the room by 2.5, and the product is the number of materials used for the wall. Such as 20 square meters of room materials used for 20 × 2.5 = 50m. There is also a more precise formula: S = (L/M + 1)(H + h) + C/M where: S - length of wall material required (m) L - deduction of windows, doors, etc. The total length of the rear wall (m) M - the width of the wall material (m), plus 1 as the margin of the mosaic pattern; H - the height of the desired wall material (m) h - on the wall material The distance between two identical patterns (m) C—the area of ​​the wall required for up and down the window, door, etc. (square meter) 2. Field measurement, this method is more accurate, first understand the width of the wall material to be selected, According to this width, the perimeter of the room wall (excluding doors, windows, etc.) is measured. In the perimeter, there are several widths of the wall material, that is, a few frames are required. Then measure the height of the wall that should be affixed. Multiply this by the number of walls, which is the length (in meters) of wall material required for the wall outside the door and window. Finally, the length of material required for the wall under the window, irregular corners, etc. is measured by this method, and it is added to the calculated length, which is the total length. This method is more suitable for fine-grained patterns, without special alignment of the wall material when splicing.
7. The method for estimating the amount of paint introduced a simple calculation method:
The room area (square meters) divided by four, the height of the wall to be painted (in decimeters) divided by four, the sum of the two is the number of kilograms of paint required. For example, a room with an area of ​​20 square meters and a wall height of 16 decimeters (except for 12-millimeter wall skirts), then, is (20÷4)+(16÷4)=9, ie 9 kg of paint can be painted on the wall two all over.

Some calculation formulas for decoration costs
1, floor tile usage: (note generally different room type loss rate is different about 1-5%) per 100 meter usage = 100 / [(block length + mortar width) × (block width + mortar width)] × ( 1 + loss rate) For example, the use of retro floor tiles size 0.5 × 0.5M, seam width of 0.002M, loss rate of 1%, 100 square meters need to use the number of blocks: 100 square meters amount = 100 / [(0.5 + 0.002 ) × (0.5 + 0.002) × (1 + 0.01) approximately equal to 401 tiles total price = number of tiles × floor tile unit price
