1, floor tile usage: (Note generally different room type loss rate is different about 1-5%)
The amount per hundred meters = 100 / [(block length + gray seam width) × (block width + gray seam width)] × (1 + loss rate)
For example, the size of the retro floor tile is 0.5×0.5M, the width of the joint is 0.002M, the loss rate is 1%, and the required number of blocks for 100 square meters is:
100 square meters = 100/[(0.5 + 0.002) × (0.5 + 0.002) × (1 + 0.01) approximately equal to the total price of 401 tiles = number of tiles × number of tiles
2, ceiling usage:
Roof plate usage=(length-shield length)×(width-shield width)
For example, the amount of PVC plastic ceiling can be calculated from the net size area. The unit price of PVC plastic sheet is 50.81 yuan per square meter, the shield length and width are 0.24M, the length of the canopy is 3M, and the width is 4.5M. The dosage is as follows:
Roofing plate usage = (3-0.24) x (4.5-0.24) approximately equal to 11.76 per square meter
3, package door dosage:
Package door material usage = door outer frame length × door frame width, for example (as shown in the figure) with composite wood package door, door outer frame length 2.7M, width 1.5M, then its material usage is as follows:
Package door material dosage=2.7×1.5=4.05 square meters
4, wallpaper usage:
Wallpaper Usage = (High - Shielded Length) × (Width - Shielded Width) × Number of Walls - Door Area - Window Area (For example) Wall Area is calculated as net size, shield is 24CM, wall height is 2.5M, width is 5M, The door area is 2.8 square meters and the window area is 3.6 square meters. The dosage is as follows:
The amount of wallpaper used = [(2.5-0.24) × (5-0.24)] × 4-2.8-3.6 is equal to about 36.6 square meters. It is a calculation of the amount of materials used. After multiplying the amount of materials used for decoration of each part by the respective unit price, Adding up, you get the total material cost of the renovation project.
5, floor dosage: (solid wood)
Longitudinal usage = room length / length of floor tile Lateral usage = room width / width of the floor tile If you encounter endless, use the carry method, do not round, but less than half of the longitudinal calculation 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 ways to calculate wall materials:
1. Calculated by the formula, the area of ​​the room is multiplied 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
Including: S - length of required wall material (m)
L--Total length of the wall after deducting windows, doors, etc. (m)
M - the width of the wall material (m), plus 1 as a splicing pattern margin;
H--the height of the required wall material (m)
h - distance between two identical patterns on a wall material (m)
C--the area of ​​the wall required for up and down windows, doors, etc. (square meters)
2. On-site measurement, this method is more accurate, first understand the width of the wall material to be selected, measure the perimeter of the room wall (excluding doors, windows, etc.) according to the width, there are several wall materials in the perimeter Width, that is, a few stickers. 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.
How to prevent the bathroom decoration "family bathroom" has become an important part of the home, enjoy the fresh and fun, comfortable and natural feeling it brings us to pursue. As a functional area with a large amount of water, during the renovation, the need for waterproof and moisture proof should be taken into account, such as the laying of tiles, ceiling treatment, pipeline installation and equipment selection, and careful arrangements should be made.
Wall tiles and stone should be laid under the surface to make a waterproof layer. The cement mortar should be used to level the ground and apply waterproof coating. Afterwards, a layer of cement mortar of 1 to 2 should be used as a bonding layer to adorn the tiles and other decorative materials. After being watered, it is tamped with wooden boards to achieve a firm and tight joint. Before stone paving, back-coating should be done to reduce the phenomenon of “water stainsâ€. The contact area of ​​the waterproof layer with the wall should be turned upwards, about 25 to 30 cm above the ground, and the wash cabinet should be 1.0 to 1.2 meters above the ground, and the shower should be 1.8 meters above the ground. If you do paint decoration should first brush waterproof putty and use waterproof coating. The ground surface layer of flowing water should be drained to the ground, and the pan and water should not fall. After 24 hours of storage test, there is no leakage.
Ceilings are recommended to use microporous aluminum gussets to enhance ventilation and prevent condensation. If you do plasterboard ceiling, you should first brush waterproof putty, and then brush waterproof coating; PVC ceiling is easy to produce condensation, and drop, should be used with caution.
Pipeline installation to avoid changing the original up and down the pipe, must be horizontal and vertical decoration, laying a firm, slope meet the requirements. Valves, faucets are installed with a flat surface, flexible and easy to use, bright tube brush anti-rust paint, dark pipe brush anti-corrosion paint. The water supply pipe is closely connected with accessories and appliances, and there is no leakage through the water test. Floor drain design is still based on the above drainage pipeline, and the surface should be slightly lower than the ground.
The sanitary appliance is installed in the correct position and the appliance has to be level on its top edge. Bathroom appliances should be branded and have better waterproof performance. For example, shower warm lamps that are used in wet environments for a long time should be made of stainless steel. The anti-corrosion performance is better. Also, waterproof power switches, cables, and plugs are used. When it is powered off, it is not afraid of water showering or water splashing. It will not cause leakage or damage. Need to be equipped with waterproof shades, waterproof sockets and so on.
In the bathroom, the use of wooden materials should be circumvented. When it is really necessary to use it, it is necessary to use a fireproof board or a full mixture of oils, which can be waterproof. In the ceiling or other package decoration, the hidden wooden keel needs to be painted with a waterproof coating or antiseptic.
It is very important for the bathroom to maintain a good ventilation environment. The use of good quality ventilation equipment helps to quickly evaporate moisture and vapors and keep the interior fresh and clean. Do a good job in the above aspects, you can certainly feel completely put.
