Under normal circumstances, the number of house renovation costs depends on the size of the decoration area, but the decoration area and the actual area of ​​the house is not the same, so before the renovation is necessary to measure the size of the house decoration, be aware of, reduce some Unnecessary material waste. The content to be measured in home decoration is roughly divided into several parts such as wall surface, ceiling, floor, doors and windows. 1. Calculation of Wall Area The decorative materials for wall surfaces (including cylinders) generally include: paints, paints, stones, wall tiles, wallpapers, soft bags, wallboards, baseboards, etc. When calculating the area, materials are different. The calculation method is also different. 1) The area of ​​paint, wallpaper, soft bag, and wallboard is the length multiplied by height, and the unit is calculated in "square meters". Length: Calculated by the net length of the main wall; height: from the interior floor to the floor of the floor without the skirt; from the apex of the skirt to the floor of the floor with the skirt; from the interior floor (or the skirt vertex) to the ceiling under the ceiling with the ceiling. Along with 20 cm. The area occupied by doors and windows shall be deducted, but the hole area and the area of ​​the intersection between the beam head and the wall surface shall not be deducted. 2) When affixing stone and wall tiles, calculate according to the actual shop area in "square meters". 3) Install the skirting board area according to the perimeter of the interior wall. The unit is meter. 2, the calculation of the top area The decorative materials of ceilings (including beams) generally include paints, ceilings, vertices (decorative flowers) and lighting ceilings. The area of ​​the shed construction is calculated in terms of “m2†according to the net area between the wall and the wall. The area occupied by the partitions, pillars, sampans and nearby chimneys that pass through the shed is not deducted. The length of the vertices is calculated in metres in terms of the net perimeter of the interior wall of the house. 3. Calculation of floor area The floor decoration materials generally include: wooden floors, floor tiles (or stone), carpets, stair treads, and handrails. 1) The ground area is calculated as "square meters" based on the net area between the wall and the wall. The area occupied by the partition wall, the columns passing through the ground, the plutonium, and the nearby chimney shall not be deducted. 2) The area of ​​staircase is calculated according to the actual development area in "square meters", and the area occupied by staircase wells within 30 cm in width is not deducted; the length of stair handrails and railings can be projected at their full horizontal length (excluding the part of the wall) Multiply the coefficient by 1.15 to calculate "extended meters". The length of other railings and handrails is directly calculated as “extended metersâ€.
