How to paint a roll up garage door?


Painting a roll-up garage door can be a great way to enhance the curb appeal of your home and protect the door from the elements. Whether you want to freshen up the existing color or completely change the look, painting a roll-up garage door is a relatively straightforward process. In this article, we will guide you through the steps involved in painting a roll-up garage door, from preparation to finishing touches.

Materials Needed

Before you begin, gather the following materials:

– Paint (specifically formulated for exterior use)
– Primer (if necessary)
– Paintbrushes (angled brush and a wide brush)
– Roller and roller cover
– Paint tray
– Drop cloths or plastic sheets
– Painter’s tape
– Sandpaper (medium and fine grit)
– Cleaning solution (such as mild detergent or TSP)
– Bucket
– Water hose or pressure washer
– Safety goggles
– Respirator mask
– Gloves


Proper preparation is crucial for a successful paint job. Follow these steps:

1. Clean the surface: Start by cleaning the garage door thoroughly to remove any dirt, grime, or loose paint. Use a mixture of mild detergent or TSP and water, scrubbing the surface with a brush or sponge. Rinse with a water hose or pressure washer and allow it to dry completely.

2. Remove any loose paint: If there are any areas with peeling or flaking paint, use a scraper or sandpaper to remove it. Smooth out the edges of the remaining paint to create a seamless surface.

3. Sand the surface: Lightly sand the entire garage door to create a rough surface that will help the paint adhere better. Start with medium-grit sandpaper and then switch to fine-grit sandpaper for a smoother finish.

4. Protect surrounding areas: Cover the ground and any nearby surfaces with drop cloths or plastic sheets to protect them from paint splatters. Use painter’s tape to mask off any areas you don’t want to be painted, such as windows or trim.

Painting Process

Follow these steps to paint your roll-up garage door:

1. Apply primer (if necessary): If you’re painting a metal door or if the existing paint is in poor condition, it’s recommended to apply a coat of primer before painting. This will help the paint adhere better and provide a more even finish. Follow the manufacturer’s instructions for the specific primer you’re using.

2. Start with the edges: Begin by painting the edges of the garage door using an angled brush. This will allow you to reach into the corners and edges more easily. Use long, smooth strokes and try to maintain a consistent thickness of paint.

3. Use a roller for the main surface: Once the edges are done, switch to a roller and paint the main surface of the garage door. Start from the top and work your way down, using long vertical strokes. Apply the paint evenly, ensuring there are no drips or uneven areas.

4. Allow the first coat to dry: Follow the drying time mentioned on the paint can. Once the first coat is dry, inspect the surface for any missed spots or areas that need touch-ups. If necessary, apply a second coat following the same process.

5. Finishing touches: Once the final coat is dry, remove the painter’s tape carefully. Inspect the garage door for any imperfections or drips. Use a small brush or touch-up roller to fix any issues.


Painting a roll-up garage door can be a rewarding project that enhances the appearance of your home. By following the steps outlined in this article, you can achieve a professional-looking finish. Remember to take your time, properly prepare the surface, and use high-quality materials for the best results.
