General knowledge of coating: calculation method of wall material consumption

Core tip: as for the product consumption, in fact, our wall area is very easy to calculate As long as you know the use area at home, you can easily apply the formula to calculate the wall area, or you know the building area at home If the use area at home is 90 square meters, the wall area is 90 × 3.5 = 315 square meters If you only know the building area, you can use the building area ÷ 1.3 the outgoing area is the use area of your home, for example, the building area of your home is 117 square meters ÷ 1.3 = 90 square meters Application scope and advantages of roller ceramic coating Recommended introduction: the surface of ceramic rubber plate used for roller ceramic coating is cast into durable rubber plate by hundreds of independent small ceramic pieces Each ceramic piece has raised characteristics Under general conveyor belt pressure, thousands of unique cast bumps can produce positive traction, prevent slipping and extend the service life of conveyor belt roller At the same time, the bottom layer adopts high-quality rubber, which has strong elasticity and can play a good impact resistance role The scope of application of roller ceramic coating is one three six 83857180 (the same as V) 1 Roller coating in extremely harsh working environment 2 The belt joint is not suitable for fixing with iron buckle; 3 It is suitable for leather Home of coatings: As for the product consumption, in fact, our wall area is very easy to calculate As long as you know the use area at home, you can easily apply the formula to calculate the wall area, or you know the building area at home If your use area is 90 square meters, the wall area is 90 × 3.5 = 315 square meters If you only know the building area, you can use the building area ÷ 1.3 For example, the building area of your home is 117 square meters ÷ 1.3 = 90 square meters, and then 90 × 3.5 is the wall area of your home So how to calculate the amount of wall materials in my house? Here I still take the 90 square meter house as an example: first of all, we need to clarify the scope of wall construction at home Generally speaking, the kitchen and bathroom at home should be tiled, and the living room, bedroom, corridor, study, garage, balcony and other positions should be decorated Because the kitchen and toilet are to be tiled, the area obtained by using the kitchen and toilet area × 3.5 minus the area to be used is the area to be tiled For the living room and bedroom to be decorated, let's take one living room and two bedrooms to be decorated as an example Let's assume that the use area of our house is 90 square meters, and the use area of the kitchen and bathroom is 7 square meters and 4 square meters Then we need to paint the wall area as follows: Formula: (the use area of the house - the use area of the kitchen - the use area of the toilet) × 3.5 = the wall area to be painted That is, (90-7-4) × 3.5 = 276.5 square meters The more accurate calculation method is to measure the area of each wall, subtract the use area of all doors, and subtract half of the window area to get the actual area But we usually apply the formula, because the formula can better grasp the material consumption After calculating the wall area, we need to measure the flatness of the wall in order to grasp the material consumption more accurately You can use a steel guiding rule or a right angle board in combination with a tape measure Suppose that the flatness of the wall measured is 0.5mm for 130m2 and 5-8mm for 140m2 Note: there may be other places with varying degrees of bumps, if any, in the calculation Now we can calculate what materials we need and how much we need 1： The interface agent is 18 kg of material diluted and mixed with water in a ratio of 0.5, and then applied to the whole wall Theoretically, it can be applied to about 270 square meters (the amount of one coat) The actual application may be less, according to the quality of the wall and the degree of pulverization It's usually one pass According to the current house needs two barrels (actually more than one barrel) two: caulking gypsum, which is relatively high-end in the current market Now the popular product is water-resistant putty, but it is still used in some areas Cellulose, gypsum powder, Shuangfei powder and other materials are prepared on site.) Caulking gypsum is the material for wall trunking and internal and external corners 90 square meters of house use between one and two bags (because different families have different lines, usually two bags are used according to long-term decoration experience) 3： Leveling mortar, leveling mortar is the benchmark leveling for the places with large concave and convex on the wall, which is used to make up for the lack of putty powder (too large concave and convex putty powder will crack if it is too thick for a long time) If the flatness of the wall is within 0.5mm (building wall standard), you can use putty powder directly without leveling mortar For the local leveling of our wall, you need to use putty powder To 7 bags of thick leveling mortar The dosage algorithm is: front area ＞ 0.5mm ÷ product leveling area of each bag = product dosage 4: after the wall surface has been leveled, the wall surface is roughly flat, and then the wall surface is precisely leveled The dosage algorithm is: wall area ÷ single product painting area = product dosage according to the painting area in this case is 276.5 ÷ 20 = 14 The case needs to use 14 bags of putty powder (theoretical amount) There will be a little error in the actual amount according to the amount of decoration master, so we usually arrange one more bag for the actual delivery 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,
