Changing the paint on football fields is a meticulous process that involves several steps and a dedicated crew. The process begins with measuring and marking the field, using ropes and templates to ensure accuracy. After the measurements are made, the crew applies paint to create the necessary lines, logos, and markings. To remove existing paint, a scrubbing solution is used, and the field is then raked and dried before repainting. The type of paint used is typically water-soluble or chalk-based, specifically designed for turf, and applied with aerosol paint machines, stripe machines, or handheld wands. The process is time-consuming, often taking a crew of 12 people about eight hours to complete.

What You'll Learn
Using stencils and tape
Stencils and tape are essential tools for marking out lines, logos, and other field markings on football fields. Here's a step-by-step guide on how to use them effectively:
Preparation
First, you need to measure out the field and determine the locations for your designs, lines, or logos. This step is crucial for accurate and precise markings. Use string lines or ropes to section out the surface of the field and ensure perfect alignment. Yard lines, for example, can be marked by measuring the required distances (20, 30, 40, etc.) on both sides of the field and then connecting the points with string or rope.
Securing Stencils
Once you've completed your measurements and markings, it's time to secure your stencils. Stencils are templates, typically made from cardboard or plastic, that ensure uniform paint application. Place your stencil in the desired location and secure it with tape or weights. This will prevent the stencil from moving and ensure crisp, clear lines.
Painting
Now, you're ready to start painting. For filling in larger areas or logos, aerosol paint machines or handheld aerosol cans can be used. Spray the paint within the secured stencil area, ensuring an even coat. If you're marking lines, a turf paint stripe machine or wand attached to a paint machine can be used. These machines often use aerosol cans inserted upside down or a striping wheel in direct contact with the turf.
Clean-up and Additional Tips
After painting, ensure any paint outlines or overspill is cleaned up. Work with a helper who can assist in lifting the stencil gently to avoid paint spreading to unwanted areas. They can also help hold stencils and templates firmly against the outlines.
If you're working on artificial turf, remember to use water-soluble or chalk paint specifically designed for painting turf. Natural grass fields may require different types of paint, and you can simply let the grass grow out to cover any old markings. Additionally, consider using an automatic field painter or templates to save time and improve accuracy.

Scrubbing off paint
When it comes to the type of paint, water-soluble or chalk paint is typically used on turf specifically because it is easier to scrub off. If the paint is more permanent, a paint stripper can be applied, and once the paint bubbles, it can be scraped off with a metal putty knife. If there is still paint remaining, the stripper can be reapplied, and the remaining paint can be scrubbed off with steel wool.
For smaller jobs, scrubbing off paint by hand is also an option. Brushes with plastic bristles are recommended for turf to prevent damage to the turf fibres. The direction of scrubbing should be varied to ensure that all the paint is removed.
If the field is made of real grass, the paint can simply be left to grow out, and it will disappear in one to two weeks.

Applying paint stripper
When it comes to changing the paint on football fields, one of the recommended methods is to use a paint stripper. This process can effectively remove paint from the turf, preparing it for new paint applications. Here is a detailed guide on applying paint stripper:
Firstly, it is crucial to select an appropriate paint stripper that is specifically designed for removing paint from turf or artificial grass. Read and understand the manufacturer's instructions for safe and effective use. Before applying the paint stripper, ensure you are wearing the necessary protective gear, such as gloves and eye protection, to safeguard yourself from any chemical exposure.
Now, you're ready to apply the paint stripper. Follow the manufacturer's directions for application, ensuring that you cover all the painted areas thoroughly. Once applied, wait for the paint to start bubbling, indicating that the stripper is actively breaking down the paint. This process may take some time, so be patient and allow it to work effectively.
After the paint has bubbled sufficiently, it's time to scrape off the softened paint. Using a metal putty knife, gently scrape away the paint, being careful not to damage the turf fibres. If necessary, reapply the stripper to any stubborn areas that require additional treatment. Once you have removed as much paint as possible with the putty knife, use a scrub brush with plastic bristles to address any remaining paint residue. Work carefully in a back-and-forth motion, ensuring that you do not damage the turf fibres.
For particularly stubborn spots, steel wool can be used for more aggressive removal, but exercise caution to avoid damaging the turf. After removing the paint, it is essential to clean the area with mineral spirits to neutralize any remaining stripper residue and prepare the surface for repainting. Finally, ensure that you properly dispose of the removed paint and cleaning materials according to local regulations and guidelines.

Using an automatic field painter
Painting a football field is a tedious task that requires a lot of time and manual labour. It involves measuring the field by hand using long tape measures and then pushing the line marker to apply paint to the lines. This process usually takes around 20 man-hours, depending on the number of people available.
However, with an automatic field painter, the time and effort required can be significantly reduced. The Turf Tank, for example, is a GPS-enabled line-marking robot that can paint a football field with 100% accuracy in just 25 minutes. It uses satellite positioning to place the fields, eliminating the need for manual measuring and marking. The robot can also be controlled via an app, allowing for custom dimensions and layouts.
The automatic field painter consists of two main components: the painting unit and the control system. The painting unit is a small robotic machine with nozzles that spray paint onto the field, while the control system uses sensors to detect the vehicle's location, ensuring straight lines with no overlaps or gaps. This system also controls the amount of paint used, reducing waste.
The benefits of using an automatic field painter include increased accuracy and efficiency, and cost savings. It reduces the labour required, allowing staff to focus on other tasks such as maintenance and upkeep. Additionally, the automated system can paint multiple fields daily, keeping them game-ready and providing more practice time for teams.
Overall, using an automatic field painter offers a faster, more precise, and cost-effective solution for painting football fields, enhancing the overall experience for both players and spectators.

Painting real grass
First, measure out the field and mark the locations for any logos or designs. Secure a stencil in place with tape or weights, and use a string line to ensure perfect alignment. For small areas without precise lines, a simple aerosol can may be sufficient. However, for larger surface areas, such as logos on football fields, aerosol paint machines or turf paint stripe machines are often used. These machines may use an aerosol can inserted upside down or a striping wheel in direct contact with the turf. Alternatively, a wand or handheld aerosol paint spray machine can be used, with the wand attached to a machine that contains the paint.
After outlining the design, step inside the designated space and fill it in by running the wand in lines until the entire area is covered. It is important to use water-soluble or chalk paint specifically designed for painting turf to ensure the grass is not damaged.
When it comes to removing paint from real grass, the process is relatively simple. One method is to simply let the grass grow out, which typically takes one to two weeks for the paint to become completely invisible. Alternatively, a paint stripper can be applied and then scraped off with a metal putty knife. This process may need to be repeated several times, and the field will need to be rinsed with water and dried before repainting.
It is worth noting that the colour and appearance of real grass can be altered by mowing in different directions. This technique can be used to create visual variety on the football field without the need for paint.
