How to Paint a Garage Door with a Roller?

The exterior aesthetic of your home is very important, especially if you are looking to sell the home. Your roller garage door will likely already have a coat of paint it received at the factory or the fabricator, but its color might not match the rest of the house. You might also want to paint the garage door if it is starting to show its age or came unpainted, which happens but is not very common. In this article, we are going to look at steps that will help you paint your garage door and leave it looking splendid.


Before you start painting, it is very important that you prepare the garage door. A good cleaning entails using mild soap and some water to get most of the dirt, dust, and grime off the door. If there is flaky paint on the door or other debris, you might have to use a scraper to remove it.

Next, you need to rub the door using sandpaper. This will help remove any paint or rust that remains on the door and give the door a slightly rough texture. This rough texture helps the paint adhere to the surface better. Once you are done with the sandpaper, use a cloth to wipe the door. Sandpaper leaves little bits of metal on the door, and these must be removed if you want the coats to be smooth.

Protect The Surrounding Areas

Whether you use a brush, spray, or a roller, it is likely that the paint will go where you do not want it to go. You can use plastic sheets, paper, or decorators’ tape to cover and mask off areas where you do not want the paint to go.

Apply The Primer

There are instances where you might not need to use a primer. These include when the door is already coated in a primer or the paint you use does not require it. If your garage is not made out of galvanized metal, you will not be able to paint it until you apply a primer. This is because the paint will not adhere and will flake off after a few days. Also, using a primer ensures the paint does not damage the roller shutter, and this is why it is always better to use a primer unless you are absolutely sure you do not have to.

Selecting The Paint

Apart from the color, you also need to think about the material the pain will be used on. If your roller garage door is made out of wood, you will need a completely different paint compared to situations where you need to paint a metal garage door.

Since there are lots of different types of paints for both metal and wooden garage doors, it is always a good idea to talk to a professional, so they can advise you on the best type of paint to use in your specific situation. You also need to ask for the right type of paint depending on whether you are painting or spraying the garage door.

Painting The Door

Now that the preparations are done, the primer is set and the paint is bought, it is time to paint the door. Get your protective equipment, goggles, gas masks, gloves, and the like. Next, stir the paint completely and choose a brush or roller with natural fibers. You will need to apply a thin coat from top to bottom with most people choosing to also paint left to right. However, there is nothing stopping you from painting bottom up if you are careful not to leave drips.

Applying thin layers is often best because they dry faster and reduce the chances of rough surfaces when the paint dries. You can apply a few more coats until you are satisfied with the look.

If you spray paint the garage door, the technique will have a few differences. The most common technique for spray-painting a garage door is dividing it into horizontal thirds and spraying from left to right. Ensure you have protective gear and stand about 1.5-2 feet away from the door. Spray left to right, going as slow or as fast as possible to get the best coverage.

Paint one third at a time and remember you will need three passes to complete the job. Remember one pass paints a third of the door and you need three passes for each third.

Painting In The Right Conditions

If you would like to end up with a great look and for the paint to last longer, paint in the right conditions. It should not be too hot or too cold, and it should not be raining either.
Painting a roller garage door is not very different from painting other types of garage doors. Critical steps include the preparation and selection of paint.
