Paint knowledge | calculation formula of wall paint construction area for home decoration

Core tip: interior wall paint is the top coat, which is often referred to as latex paint It is one of the main decorative materials used for wall in home decoration, accounting for a considerable proportion in the cost of basic decoration For the owners of home decoration, when buying wall paint, they should consider how much is suitable If they buy more, they will waste it If they buy less, they will not be enough Today, let's see how to calculate the area of the wall paint with the decoration net 1、 Calculation formula of wall paint construction area: 1 Wall paint construction area = (building area × 80% - 10) × 3 building area is the purchase area The actual utilization rate is generally about 80%, and the kitchen and toilet are generally about 80% Shenyang steel structure fireproof coating construction expert punde Building Fire Engineering Co., Ltd Recommended introduction: since its establishment, Shenyang punde Construction Fire Engineering Co., Ltd has cultivated a group of professional construction teams with excellent equipment, rich experience and serious responsibility with advanced and scientific management methods and strict engineering quality assurance and after-sales service system It has undertaken a number of fire system installation projects, which has been praised by customers Every idea and special requirement of you will be fully considered by us and fully realized in the construction technology, which will become the cornerstone of our successful long-term development We are looking forward to your invitation, to provide you with quality services and high-quality technical support! All construction coatings have passed ISO9001 Paint Home News: interior wall paint is the top coat, which is often referred to as latex paint It is one of the main decorative materials used for the wall in home decoration, accounting for a considerable proportion in the cost of basic decoration For the owners of home decoration, when buying wall paint, they should consider how much is suitable If they buy more, they will waste it If they buy less, they will not be enough Today, let's see how to calculate the area of the wall paint with the decoration net 1、 Calculation formula of wall paint construction area: 1 Wall paint construction area = (construction area × 80% - 10) × 3 construction area is the purchase area The actual utilization rate is about 80% now The kitchen and toilet generally use ceramic tiles and aluminum gusset plates, most of which are 10 square meters The area obtained by this calculation method includes ceiling and ceiling The influence on the construction area of the wall paint is not great, so it can be ignored (the result of this formula may be the closest to the actual area) 2 Amount of wall paint: according to the requirements of standard construction procedures, the thickness of primer is 30 microns, the construction area of 5-litre primer is generally 65-70 square meters; the recommended thickness of wall paint is 60-70 microns, and the construction area of 5-litre wall paint is generally 30-35 square meters 3 Primer amount = construction area ÷ 70; finish amount = construction area ÷ 35 For a room with a building area of 120 square meters, the amount of paint required is the construction area of wall paint = (120 × 80% - 10) × 3 = 258 square meters, the amount of primer = the construction area ÷ 80 (coating rate / 1 time) = 258 / 80 = 3.3 (barrel), that is, the amount of 4 barrels of top paint = the construction area ÷ 45 (coating rate / 2 times) = 258 / 45 = 5.7 (barrel), that is, the amount of 6 barrels of wall paint is calculated: First of all, the painting area should be calculated With the painting area, the painting area can be divided by the coating area of each liter of paint to obtain the required amount of paint For general interior wall painting, there is an empirical formula to calculate the painting area: the amount of paint required for one layer of painting is liter = (building area x2.5) / painting area per liter For example: for a new house with two rooms and one hall of 80 square meters, the painting area is about 200 square meters of the wall, each 5-in-1 can be painted with 13-16 square meters, and a barrel of 5-in-1 Dulux can be painted with two layers of 40 square meters of the wall, so the painting of this room, including the ceiling, requires a total of 5 barrels of 5-in-1 Dulux emulsion paint For wall paint, painters usually charge by square meters, but before painting, the owner often ignores how to charge the door and window area Some people think that the door and window area can be deducted, but it is understood that no matter it is the decoration company or the painter, the garden furniture in the living room Generally, the area of doors and windows will not be removed when painting the wall paint, but there are charges due to the high technical difficulty when painting the side wall of doors and windows, but the charging standard is not uniform It is suggested that the owner should negotiate with the construction team about the price when painting the wall paint, so as to avoid disputes afterwards Home of coatings is specialized in coatings, diatom mud, paint coating, coating technology, fire retardant coating news and coating, diatom mud, paint coating, coating technology, fire retardant coating decoration knowledge and decoration renderings,
