What You'll Learn
A Boeing 737 requires 70 gallons of paint
Painting an aircraft requires a significant amount of paint, and the volume needed depends on the size of the plane and the intricacy of the colour scheme. A Boeing 737, for instance, requires approximately 70 gallons (265 litres) of paint. This amount can vary, with some sources citing 260 litres as the necessary volume for a 737. The process typically involves three layers of paint: primer, base coat, and top coat. Each layer is approximately 0.1 mm thick.
The weight of the paint is an important consideration in aircraft painting. The paint on a 737 can add around 555 pounds (252 kg) to the weight of the plane. This additional weight can impact the aircraft's performance and fuel efficiency. To minimise weight, some airlines opt for special textures or designs that require less paint, such as transfer stripes or a plain aluminium body.
The cost of painting a 737 can range from $100,000 to $200,000, depending on the colours chosen and the number of colours used. This expense includes the preparation process and the paint itself. Painting a 737 can take up to two weeks to complete, depending on the complexity of the colour scheme.
Compared to other aircraft, the 737 requires a relatively modest amount of paint. Larger planes, such as the Boeing 777, require 110 gallons (415 litres), while the Airbus A380 superjumbo can need up to 950 gallons (3600 litres) of paint. The painting process for an A380 can take up to three weeks, involving the coverage of over 3100 square metres of surface area with paint.

The paint weighs around 300-555 lbs
Painting an aircraft is no small feat—it can take up to three weeks to complete, depending on the aircraft's size and the complexity of its colour scheme. A Boeing 737 requires approximately 70 gallons (or 265 litres) of paint. Given that a gallon of paint weighs anywhere between 7 and 12 pounds, the paint for a 737 would weigh between 490 and 840 pounds. This means that the paint weighs around 300-550 lbs, depending on the type of paint used.
The weight of paint is determined by the number of pounds of paint per gallon (or kilograms per litre). This makes it easier for manufacturers to determine the volume of paint needed for an aircraft. The weight of paint is also affected by its viscosity, with the applied volume used to determine the total weight. It is crucial to quantify the exact weight, as it contributes to the empty weight of the aircraft.
The paint job on an aircraft typically involves three steps: primer, base coat, and top coat. Each layer of paint is approximately 0.1 mm thick, and the top coat gives the plane its signature shine. While a Boeing 737 requires about 70 gallons of paint, larger aircraft like the Boeing 777 need 110 gallons, and the Airbus A380 superjumbo requires up to 950 gallons.
The weight of the paint used on an aircraft is impacted by the type of paint and its ingredients. Paints with thicker pigments and additives like sand tend to be heavier. Oil-based paints, for instance, have thicker pigments and higher densities, contributing to a greater weight. On the other hand, water-based paints may be lighter when dry due to the evaporation of water.
When applying paint to an aircraft, not all of it adheres to the surface. If the solid paint weighs 5 lbs per gallon, only about 2.5 lbs are deposited on the aircraft, with the rest falling to the ground. This wasted paint cannot be reused as it attracts impurities, which can result in a poorer finish or faster wear.

Painting takes up to two weeks
Painting an aircraft is a time-consuming process that can take up to two weeks or even longer, depending on the size of the plane and the complexity of the paint job. In the case of a Boeing 737, the painting process typically involves several steps and can take around two weeks to complete.
The first step in painting a 737 is to prepare the aircraft's surface. This includes cleaning and sanding the exterior to ensure that the paint will adhere properly. Once the surface is prepared, the next step is to apply a primer. The primer serves as a base coat and helps the subsequent paint layers adhere better. After the primer is applied, it needs to be given adequate time to dry, which can take several hours.
The next step in the process is to apply the base colour. This typically involves spraying the aircraft with a high-volume, low-pressure spray system, which allows for an even and thin layer of paint to be applied. The base colour is usually applied in multiple thin coats to ensure a consistent finish. Depending on the desired colour and complexity of the design, additional colours or decals may be applied. For example, some airlines may choose to add their logo or other graphics to the aircraft.
After the base colour and any additional designs have been applied, a top coat is typically sprayed on. This final layer gives the plane its characteristic shine and helps protect the paint job from the elements. Similar to the primer, the top coat needs sufficient time to dry, which can take up to a full day.
In addition to the painting process itself, there may be other factors that contribute to the two-week timeline. For example, if the aircraft is undergoing a complete makeover, the old paint may need to be stripped, which can add several days to the process. Furthermore, the application of decals or other custom designs can also extend the timeline, as these often require precise masking and additional layers of paint.
Overall, painting a 737 is a complex and time-intensive process that requires careful planning and execution. While two weeks is a standard timeframe, it can vary depending on the specific requirements and the expertise of the painting team.

Three layers of paint are applied: primer, base, and top coat
Painting an aircraft is a complex and time-consuming process. The amount of paint required depends on the size of the aircraft and the intricacy of the colour scheme. A Boeing 737 requires approximately 70 gallons or 265 litres of paint. This is significantly less than larger aircraft like the Boeing 777, which requires 110 gallons (415 litres), or the Airbus A380, which can need up to 950 gallons or 3600 litres.
The paint job on an aircraft typically involves three layers: primer, base coat, and top coat. Each layer serves a specific purpose and contributes to the overall finish and protection of the aircraft's exterior.
The first layer, the primer, is essential for preparing the aircraft's surface for the subsequent paint layers. It ensures that the base and top coats properly adhere to the surface, preventing issues like flaking and chipping. Without a primer, the paint may not bond effectively to the aircraft's exterior.
The second layer is the base coat, which gives the aircraft its intended colour. This layer is crucial as it cannot be left alone due to the absence of hardeners or strengtheners. A standalone base coat would result in blemishes and allow moisture to accumulate, leading to rust.
The final layer is the top coat, which is responsible for the aircraft's shiny appearance. It provides a glossy finish and also serves a protective function, safeguarding the base coat and the aircraft from environmental factors like rain, snow, and UV rays.
The application of these three layers is a meticulous process, typically carried out using a High Volume Low Pressure (HVLP) paint sprayer or a turbo sprayer. This equipment allows for an even and thin application, with each layer of paint usually measuring around 0.1 mm in thickness.
