Coating knowledge: how to calculate the area and amount of emulsion paint?

Core tip: [news] lacquer coating is a special main material in family decoration It is understood that in general family decoration, the expenditure of lacquer coating only accounts for about 5% of the whole decoration cost, but accounts for 80% of the whole decoration area 100% determines the overall decoration effect and room environment, directly affecting family health In the decoration contract, painting is also the easiest place to set traps How to calculate the painting area and amount? Calculation method of emulsion paint: each barrel of emulsion paint has theoretical unit brushing area, which generally refers to the number of areas to be brushed once, while in actual brushing, it needs to be brushed twice Which is the price of Dajin diatom mud Recommended brief introduction: which is the price of Dajin diatom mud? How to buy genuine diatom mud? Guangdong diatom mud agent suggests placing a basin of cold water in the air conditioning room, so that the diatom mud wall can breathe effectively The feature of the breathing wall is obvious When the indoor air is dry, the diatom mud wall will release the absorbed water quickly Put it out to help regulate the indoor dry humidity It is suggested to place a basin of cold water in the air conditioning room, so that the wall of diatom mud can breathe effectively The feature of the wall that can breathe is obvious When the indoor air is relatively dry, the wall of diatom mud will absorb the water Paint Home News: [news] glue paint is a special main material in family decoration It is understood that in general family decoration, the expenditure of glue paint only accounts for about 5% of the whole decoration cost, but accounts for 80% of the whole decoration area 100% determines the overall decoration effect and living environment, and directly affects the health of the family In the decoration contract, painting is also the easiest place to set traps How to calculate the painting area and amount? Calculation method of emulsion paint: each barrel of emulsion paint has theoretical unit brushing area, which generally refers to the number of areas to be brushed once, while in actual brushing, it needs to be brushed twice The general calculation method is: the quantity to be purchased = the building area of the house × (2.5-3) ÷ (theoretical brushing area per unit ÷ 2) Among them, the parameter 2.5-3 is mainly determined by the height of the room and the size of the doors and windows If the actual area of the room is known, the parameter selection should be 3-3.2 Calculation method of paint consumption: Method 1: rough calculation method: floor area × 3 ÷ theoretical painting area of two times = accurate calculation method of using barrels: (wall area + ceiling area - door and window area) ÷ theoretical painting area of two times = using barrels note: (room length + room width) × 2 × room height = wall area (including door and window area) Simple calculation of the amount of paint: room area (M2) / 4 + wall height (decimeter) / 4 = kg of paint required note: it can be painted twice, 6kg of paint is equivalent to 5L method 2: calculation formula of wall paint construction area: wall paint construction area = (building area × 80% - 10) × 3 building area is the purchase area, and the actual utilization rate is generally about 80%, Generally, the kitchen and toilet use ceramic tiles and aluminum gusset plates, most of which are 10 square meters The area obtained by this calculation method includes the ceiling The ceiling does not have a great impact on the construction area of the wall paint, which can be ignored (the result obtained by this formula may be the closest to the actual area) Paint quantity: according to the requirements of standard construction procedures, the thickness of primer is 30 microns, and the construction area of 5-litre primer is generally 65-70 square meters; the recommended thickness of top coat is 60-70 microns, and the construction area of 5-litre top coat is generally 30-35 square meters Primer amount (5L / barrel) = construction area ÷ 70; top coat amount (5L / barrel) = construction area ÷ 35: the construction area of 18 liter primer is generally 250 square meters; the construction area of 18 liter top coat is generally 125 square meters; primer amount (18L / barrel) = construction area ÷ 250 top coat amount (18L / barrel) = construction area ÷ 125 note: paint construction, one primer and two finishing coats For example, for a room with a building area of 120 square meters, the amount of paint needed (taking 5L package as an example): construction area of wall paint = (120 × 80% - 10) × 3 = 258 square meters, primer amount = construction area ÷ 70 = 258 / 70 = 3.7 (barrel), that is, 4 barrels of finish paint amount = construction area ÷ 35 = 258 / 35 = 7.7 (barrel), that is, 8 barrels can be calculated, and the amount of paint used in 18L package: primer amount = 3.7 × 5 / 18 = 1.02 (barrel) Topcoat consumption = 7.7x5/18 = 2.13 (barrel) paint house is specialized in coating, diatom mud, paint coating, coating process, news information and coating of fireproof coating, diatom mud, paint coating, coating process, decoration knowledge and decoration effect map of fireproof coating,
