What You'll Learn
Choose the right paint for the material
When painting a plastic light post, it is important to choose the right paint to ensure the paint job is durable and aesthetically pleasing. The type of paint selected will depend on the material of the light post.
For a plastic light post, you will need to select a paint that is specifically designed for use on plastic surfaces. Some paints are not compatible with plastic and may not adhere properly, resulting in a poor finish and reduced durability. Look for paints that are labelled as suitable for use on plastic or multi-surface paints. These paints will have the right formulation to bond with the plastic surface and provide a long-lasting finish.
Additionally, consider the environment in which the light post is located. For outdoor light posts, choose a paint that is suitable for exterior use and can withstand varying weather conditions, such as sunlight, rain, and extreme temperatures. These paints are often labelled as "exterior" or "all-weather" paints and are designed to resist fading, cracking, and peeling caused by exposure to the elements.
Another factor to consider is the colour and finish you desire. Light posts can be painted in a variety of colours, from elegant dark grey, black, and green to eye-catching gold. You can choose a paint that matches the style of your home or garden. Additionally, consider whether you want a glossy, matte, or textured finish. Each type of finish has its own visual appeal and can enhance the overall aesthetic of the light post.
Lastly, don't forget the primer. While it may not be compulsory, adding a primer layer can significantly improve the final result. Primer provides a foundation for the paint, enhancing adhesion and ensuring a more uniform finish. It also offers additional protection against corrosion and rust, which is especially important for outdoor light posts. Allow the primer to dry completely before applying the paint for the best results.

Prepare the light post by removing rust
To prepare a light post by removing rust, you can try a few different methods. Firstly, it is important to keep the light post dry as rust is a natural electrochemical process that occurs when metals return to their unrefined state due to a combination of iron, oxygen, and moisture. If the light post is already installed, you can try to prevent water from pooling by ensuring the concrete base is above ground level. Additionally, you can dig a hole and fill it with gravel to improve drainage.
If the light post is not yet installed, you can try galvanizing by attaching a block of zinc towards the bottom of the pole before burying it. This will inhibit rust for many years.
To remove rust stains, you can try the following methods:
- Wipe down the fixture with a clean cloth to remove any dust or debris.
- Soak a towel in vinegar and rub it on the stain. The acidic content will help break down mild stains, but it may require multiple attempts and some effort.
- Create a paste by mixing baking soda and water. Apply this paste to the stained areas and let it sit for about 30 minutes. Then, use a clean rag to rub and remove the paste, along with the rust stains.
- Use citric acid, which can be easily found at most health food stores. Soak the item in citric acid and let it sit for an hour or two until the rust disappears completely.
- For less severe rust, you can use steel wool or a metal brush to scour the surface and remove the rust down to the metal.
- If you're working on a pan, use a scouring pad or a potato. Rub the potato like a scouring pad, and it will react with the soap to help remove the rust.
Once you have removed the rust, you can follow the standard process of painting a light post. Start by checking the weather conditions and ensuring they are optimal for painting, typically between 50-80 degrees Fahrenheit with low humidity. Wash the light post thoroughly and let it dry completely. Then, tape off any areas you don't want to be painted, such as windows, and cover the surrounding area with newspapers to protect them from spray paint.

Prime the light post
Before you prime a light post, ensure that you are doing so in the right weather conditions. Spray paint should be applied when temperatures are between 50 and 80 degrees Fahrenheit, and humidity is below 85%. Avoid painting in direct sunlight, and make sure the light post is not too hot.
Next, wash the light post thoroughly and let it dry. If there is any rust on the post, sand it down to shiny metal and then apply a rust-inhibitive primer. If you cannot get to all the rust, just do your best to sand it down and then proceed with the painting. If the light post is made of wood, you may want to scrape, sand, and prep the surface before priming.
When you are ready to prime, tape off any areas you do not want to be painted, and put newspaper around the base to protect the surrounding area. Hold the can about 8 to 12 inches from the light post, and keep the can moving to avoid drips. Apply several light coats of primer. If you are using a spray paint that combines paint and primer, you can skip the priming step, but be aware that the paint job may not last as long.
Allow the primer to dry for the recommended time, which is typically around 15 minutes, and then apply a second coat of primer. Once the primer is dry, you can begin to apply the final coats of paint.

Paint the light post
Painting a light post can be a fun project, and it's definitely doable as a DIY task. Here's a step-by-step guide to help you paint your light post:
Prepare the Light Post:
Firstly, check the material of your light post. Different materials may require different types of paint and preparation methods. If your light post is made of metal, there might be some rust that you'll need to deal with. Use sandpaper to sand down the rust as much as possible. You can use coarse-grit sandpaper for quicker results, but finish with a finer grit for a smoother surface. If the light post is not already installed, it might be easier to work on it before installing it.
Prepare the Area:
Choose a warm, dry day for painting, ideally with temperatures above 50°F (10°C). Avoid painting in high humidity, direct sunlight, or cold temperatures. If the light post is installed, cover the areas you don't want to paint with tape and newspaper. Turn off the power to the light post at the circuit breaker to ensure safety.
Prime the Light Post:
Use a rust-inhibitive primer, especially if you're dealing with a metal light post. Primer will protect the surface from corrosion and rust, and enhance the adhesion of the topcoat. Apply the primer according to the instructions on the can, usually with light coats, and allow it to dry for the recommended time, often around 15 minutes. You may need to add a second coat of primer for the best results.
Choose a paint that is suitable for the material of your light post and the outdoor conditions it will be subjected to. Hold the paint can about 8-12 inches from the light post and keep the can moving to avoid drips. Apply several light coats of paint, allowing the recommended drying time between coats. Follow the instructions on the paint can for the best results.
Finishing Touches:
Once the paint is dry, inspect it for any light areas and touch up as needed. If you've painted the light post while it was installed, reconnect the electrical wires to the circuit wires, ensuring the power is still off. Reinstall any mounting hardware and fixture shades. Remove all painter's tape and masking materials.
Your light post should now have a fresh, new look that complements your home! Enjoy your handiwork and be sure to follow any specific care instructions for your paint to ensure its longevity.

Allow the paint to dry
Allowing paint to dry is a crucial step in the painting process, and it's important to be patient during this stage. The drying time will vary depending on the type of paint you've used and the environmental conditions. For example, if you're using a paint that requires a primer, like Rust-Oleum, the primer layer will need to dry for about 15 minutes before you can apply the final coats of paint. After applying the paint, you should allow it to dry for at least 24 hours before using the light post. This extended drying time ensures that the paint cures properly and forms a durable finish.
During the drying process, it's essential to maintain a suitable environment. Avoid painting when the humidity is too high (above 80%-85%) or when it's too cold (below 50°F). Both high humidity and cold temperatures can interfere with the paint's drying and curing process, leading to issues like longer drying times, uneven coverage, or a less durable finish. Ideally, you should paint when the temperature is between 50°F and 80°F.
Additionally, try to avoid painting in direct sunlight. An overcast day is ideal because the light post won't be too hot, which can affect the paint's adhesion and drying time. If you're painting indoors, ensure proper ventilation to promote paint drying and to protect your health.
While waiting for the paint to dry, you can inspect your work for any light areas that may need touching up. This is also a good time to clean your painting equipment, such as brushes or spray nozzles, to prevent paint buildup and ensure they're ready for future use.
Once the paint is dry to the touch, it's important to allow it to cure completely. This process may take several days, depending on the paint type and environmental conditions. During this curing period, avoid any activities that may damage the fresh paint, such as bumping or scraping the surface. By following these guidelines, you'll ensure that your paint job is given the best chance to last for years to come.
