Many refurbished people lamented that the decoration was stupid. This confusion is not only reflected in the selection of materials, but more often in the use of materials. Carefully decorated homeowners will write down the cost of each decoration, but the amount of these materials is calculated, right or not, and whether the amount is appropriate, but not every decoration owner understands. There are even some owners who have renovated a house and how many materials they have bought. It is a bit of confusion, so that a small part of the decoration company or construction staff has done a good job, so that owners spend more money. For this reason, our reporter specially consulted several professionals who were engaged in home improvement for many years and asked them to talk about the calculation methods of bulk materials in the decoration. Readers carefully study the methods introduced by professionals, dial the abacus, and make it clear that there is a possibility of saying goodbye to misleading accounts.
No neglect of hydropower projects
Hydroelectric engineering is a hidden project in decoration. After the concealment project is finished, it cannot be seen or touched. Therefore, once a problem arises, maintenance is very troublesome. However, due to the fact that the cost of hydropower projects is only a small part of the renovation, many people overlooked it. Professionals pointed out that the hydropower project is actually the first place in the renovation project and is related to family safety and should not be ignored.
In hydropower projects, the price and amount of wires are relatively large, so the quantity must be mastered. For the estimation of wires, professionals say that no ready-made formula can be applied. Because each family's life needs are different and wiring is different, different materials will be used. Professionals remind consumers that the decoration owner can allow the construction staff to make an estimate and then measure the number of meters used for the wire based on the actual alignment. Professionals use a 110-square-meter middle-to-high-end renovation house as an example, roughly consuming 4 BVs of wire BV1.5, 4 BV2.5 wires, 2 BV2.5 wires, and 2 BV4 wires. 2 bundles. However, if the decoration owner has additional requirements, the actual amount of use will be different.
Friendly reminder: In the home decoration, under normal circumstances, lighting wire can use BV1.5, socket and small number of air conditioning wires can use BV2.5, living room air conditioning wire can use BV4 can, each line is the best green use.
Tile loss needs to be estimated
The amount of ceramic tiles used in decoration is easier to estimate. In general, the length and width of each wall will be measured and the square number will be obtained. Then divided by the square number of the single tile that is seen, the number of tiles will be obtained. However, professionals remind the decoration owner that the loss rate should be taken into account. In general, the loss rate is 10% to 15%. If it is the decoration owner who pays attention to the color matching of the tiles, when buying the tiles, be sure to bring the design drawings and calculate the size to buy tiles.
Simple formula: (wall or ground square / tile length × width) / 90% = number of tiles required
Friendship reminder: When buying tiles, you must buy more tiles at a time, preferring to return instead of replenishing. Because even the best tile brand products produced in the same series and different batches may have the problem of color difference, if the replenishment is exactly the same batch of tiles, it is very likely to leave a pity. In addition, the decoration of the owner is best to discuss with the business when the purchase is good, you can return, so as to avoid the future of the tiles can only pile up corners trouble.
Cabinet area expansion estimate
In the decoration, woodwork is a big project. At present, the decoration owners choose to make the cabinet part of wood (in addition to buying off-the-shelf furniture) in three ways. One is the custom integrated home. Currently, the integrated home cabinet calculation in the market is based on the deployment area; the second is Decoration company on-site production, in general, the decoration company to the cabinet projected area to report the price, decoration owners do not know how to use the specific amount, but the thickness and quality of the required plate; the third is the decoration of the owner himself On-site production, this production method requires the owner to have a high degree of familiarity with the material.
According to professionals, because different owners require different cabinets, different cabinet heights, and different thicknesses of the plates used in different parts of each cabinet, it is impossible to use a uniform formula to calculate the amount. However, regardless of the way in which the cabinets are made, the owners can use the method of expanding the area to roughly calculate the amount of use.
Friendship reminder: At present, no matter what thickness of sheet material in Fuzhou market is 1.22 × 2.44 meters, as long as the use of the principle of the unfolded area to add the area of ​​the same board in the cabinet, and then divided by 1.22 × 2.44 meters, The approximate number of sheets can be obtained. Professionals said that due to the height restrictions of the cabinet, the consumption of sheet metal is relatively large. If the decoration owner is skilled in calculating and can make full use of the sheet, he will save more money by saving materials.
Pay attention to coating rate
The paint is the last process and the most critical one in the decoration. Many decoration owners are very concerned about how to calculate the amount of paint, how to grasp the standard, and then they can take the initiative in the decoration so as not to be led by some bad painters. .
In fact, each brand, the paint coating rate (ie brushing area) is different, and the use of roller brushing and spraying the amount of paint is different.
However, the amount of paint still has a formula to follow.
Simple formula of wall paint: {Set area-(Balcony + kitchen + bathroom floor area)} × 2.8 = Total brushing area
Total painting area/paintable area indicated on the paint bucket = number of barrels purchased
Friendship reminder: At present, 5 liters of paint on the market can be roughly painted in an area of ​​60 square meters; 18 liters of paint can roughly be painted on an area of ​​200 square meters again. Wall paint is a bottom two. Wood paint 1000 grams can brush 13 to 16 square meters of the area again, wood paint is two bottom three or four sides.
In addition, the wallpaper is also a small part of the decoration. In the past few years, more and more families have chosen to use wallpapers, and their ever-changing images can make decoration owners feel good and make homes rich and colorful.
The calculation of wallpaper is also relatively simple. The simple formula is: width of wall / width of wallpaper × height of layer / 90% (loss rate) = amount
