How To Paint Exterior Door Knobs Like A Pro

Painting your exterior door knobs is a great way to upgrade your doors and add unique colour accents without the cost of replacing the hardware. It is a simple, budget-friendly way to give your door knobs a fresh look. All you need is a screwdriver, some sandpaper, a can of paint, and a few other supplies.

Choosing the right paint for exterior door knobs

Painting your exterior door knobs is a great way to upgrade your doors without breaking the bank. If you choose the right paint and follow the right process, your paint job can last for years.

Choosing the Right Paint

The first step to painting your exterior door knobs is to choose the right paint. You will need to use a paint that is suitable for metal surfaces and can withstand both indoor and outdoor use. Look for a paint that is specifically designed for metal surfaces and that is durable enough for exterior use. Some popular options include Rust-Oleum and Krylon spray paints. In addition to the paint, you will also need a metal primer to ensure that the paint adheres properly to the knobs.

Preparing the Knobs

Before you start painting, you will need to remove the knobs from the door. This will allow you to work on them more easily and ensure an even finish. Take pictures as you go so that you can remember how to reassemble the knobs later. Once the knobs are removed, clean them with steel wool or a degreaser to remove any oil, grime, or dirt. You can also use sandpaper to scuff up the surface of the knobs, which will help the paint adhere better. Just be careful not to sand off the hardware's finish; sand just enough to create a dull surface.

Painting the Knobs

Now it's time to start painting! Work in a well-ventilated area and place the knobs on a stable base, such as a block of Styrofoam or cardboard. Insert a small piece of folded painter's tape into the keyhole to prevent paint from getting into the lock mechanism. Start by applying a coat of metal primer, following the manufacturer's directions. Allow the primer to dry thoroughly before moving on to the next step. Once the primer is dry, apply a coat of metallic spray paint. Again, follow the manufacturer's instructions and allow the paint to dry completely before handling the knobs. For best results, apply multiple thin coats of paint rather than one heavy coat.

Clear Coat (Optional)

If you want to add an extra layer of protection, you can apply a clear coat to your painted knobs. Choose a glossy or matte clear coat and apply it according to the manufacturer's directions. Allow the clear coat to dry completely before reinstalling the knobs.

Reinstalling the Knobs

Once the paint and clear coat (if used) are completely dry, you can reinstall the knobs on the door. Use the pictures you took during the removal process to guide you. Be careful not to scratch the newly painted knobs while screwing them back in.

Preparing the door knobs for painting

Step 1: Remove the Door Knobs

Start by removing the door knobs and lock mechanisms from the door. This can be done using a screwdriver. You may also choose to tape off the surrounding area and paint the hardware while it is still attached, but removing it will ensure an even and long-lasting finish. Take photos during this process and label the images to aid in reassembly. For example, you can label them as "inside deadbolt" and "outdoor knob". Remember to keep track of the screws and latch mechanisms.

Step 2: Clean and Scuff the Door Knobs

The next step is to clean the door knobs thoroughly to remove any oil, grime, or dirt. You can use a rag and a degreaser for this step. After cleaning, lightly scuff the surface of the door knobs with sandpaper and/or steel wool. This step is important as it helps create a rough surface for the paint to adhere to, reducing the likelihood of chipping later on. Be careful not to sand off the hardware's finish completely; just scuff it up enough so that it looks dull instead of shiny. Finally, wipe off the dust with a tack cloth or microfiber cloth.

Step 3: Protect the Keyhole

Insert a small piece of folded painter's tape into the keyhole to prevent paint from entering and clogging the lock mechanism.

Step 4: Prepare a Work Area

Set up a well-ventilated work area by placing a drop cloth or cardboard on a flat surface to protect it from spray paint. You can also use floral foam or Styrofoam to hold the door knobs securely in place while painting. This will make it easier to paint all sides of the door knobs without getting paint on your hands.

Step 5: Prime the Door Knobs (Optional)

Although some spray paints are marketed as paint and primer in one, it is recommended to use a separate metal primer for a more durable finish. Carefully read and follow the manufacturer's instructions for the primer application. Allow the primer to dry thoroughly before moving on to the next step.

Step 6: Wash the Door Knobs (Optional)

If your door knobs have a protective top coat, you may need to remove it before applying the primer. This is because the acidic component in the self-etching primer only etches metal. You can use a product like lacquer thinner and a brass brush to both degrease and remove the clear coat. Alternatively, you can check online for methods to remove the top coat without sanding, such as using acetone or denatured alcohol.

Now that your exterior door knobs are prepared, you can move on to the painting process. Remember to work in a well-ventilated area and follow the manufacturer's instructions for the paint application.

Painting techniques for best results

Painting door knobs can be a great way to upgrade your doors and add unique colour accents without the cost of replacing the hardware. Here are some techniques to achieve the best results:

Preparation

Before you start painting, it's important to prepare the surface of the door knobs. Remove any old paint, rust, or debris using sandpaper, a scuffing pad, or a wire brush. If the door knobs have never been painted before, you can use a scuffing pad to rub along the metal and create a lightly etched surface for the primer to stick to. This step is crucial, as it will help the paint adhere better and reduce the likelihood of chipping later on. Make sure to wipe off any dust with a tack cloth or microfiber cloth after sanding.

Priming

Primer is essential when painting metal, as it helps the paint stick better and prevents rust from bleeding through the new paint. Choose a primer specifically designed for metal surfaces, such as a rust-inhibiting primer like zinc chromate or iron oxide. If you're using a spray paint that is marketed as a "paint and primer in one", you can skip this step. However, for the most durable finish, it is recommended to apply a separate coat of primer first. Apply the primer according to the manufacturer's instructions, and let it dry thoroughly before moving on to the next step.

Painting

When it comes to choosing the right paint for your door knobs, opt for a paint that is specifically formulated for metal surfaces. Both oil-based and water-based paints can be used, but oil-based paints tend to be more durable and long-lasting. If you're using spray paint, hold the can about 6 to 12 inches away from the surface and use long, sweeping motions to apply the paint. For best results, apply multiple thin coats of paint rather than one heavy coat. If you're using a paintbrush, use a high-quality natural bristle brush and apply a thin layer of paint, ensuring that you follow the manufacturer's instructions for mixing the paint.

Drying and Reinstallation

Allow the paint to dry completely before reinstalling the door knobs. This typically takes around 24 hours, but it's important to refer to the manufacturer's instructions for the specific paint you are using. Once the paint is dry, carefully reinstall the door knobs, using the pictures you took during the removal process as a guide.

Drying and curing times for painted door knobs

Painting door knobs is a great way to update the look of your doors without the expense of buying new hardware. The process is simple and budget-friendly, but it does require some time and patience to ensure a long-lasting finish.

Step 1: Primer Application

After cleaning and sanding the door knobs, you will need to apply a metal primer. Some spray paints are marketed as paint and primer in one, but it is recommended to use a separate coat of primer for a more durable finish. Be sure to follow the manufacturer's directions for the best results.

Step 2: Primer Drying

Once the primer has been applied, it is important to let it dry thoroughly before moving on to the next step. The drying time will depend on the type of primer and the environmental conditions, such as temperature and humidity. In general, it is best to allow the primer to dry for at least 24 hours before handling.

Step 3: Paint Application

After the primer has dried, you can apply the metallic paint. Be sure to use a spray paint that is intended for metal surfaces and both indoor and outdoor use, if necessary. Again, follow the manufacturer's directions for application and drying times.

Step 4: Paint Drying

Allow the paint to dry completely before reinstalling the hardware. This typically takes at least 24 hours, but it is important to refer to the manufacturer's instructions for the specific paint you are using. To ensure no fingerprints are left in the paint, avoid touching the hardware during this time.

Step 5: Curing

While the paint may appear dry to the touch, it is important to allow it to cure fully for the most durable finish. Paint typically takes about a month to fully cure. During this time, try to use the door knobs gently and avoid any harsh cleaning products or abrasive materials that could damage the finish.

By following these steps and allowing adequate drying and curing times, you can achieve a long-lasting and beautiful finish on your painted door knobs.

Reinstalling painted door knobs

Step 1: Remove the Door Knobs

Use a screwdriver to carefully detach the door knobs and lock mechanism from the door. This step will ensure that you can paint all sides of the hardware evenly. Take photos as you go and label the images, such as "inside deadbolt" and "outdoor knob," to aid in reassembly.

Step 2: Clean and Prepare the Surface

Use steel wool or a degreaser to clean the hardware and remove any oil, grime, or residue. This step is crucial as it helps the paint adhere better to the surface. After cleaning, lightly sand the hardware to create a dull finish. Be careful not to sand off the hardware's original finish; just enough to scuff up the surface will do. Wipe off any dust with a tack cloth or microfiber cloth.

Step 3: Protect the Keyhole

Insert a small piece of folded painter's tape into the keyhole to prevent paint from getting into the lock mechanism. This step will ensure that your lock continues to function smoothly after painting.

Step 4: Prime the Hardware

Place the door knobs and hardware on a block of floral foam or Styrofoam to hold them in place during painting. Work in a well-ventilated area and put down a drop cloth or cardboard to protect surrounding surfaces from overspray. Spray the hardware with a metal primer, following the manufacturer's directions. Allow the primer to dry thoroughly before moving on to the next step.

Step 5: Spray Paint the Hardware

Choose a metallic spray paint that is suitable for both metal surfaces and indoor/outdoor use, depending on your needs. Apply the spray paint according to the manufacturer's instructions, usually in thin, even coats. Allow the paint to dry completely between coats, and aim for at least 24 hours of drying time before handling.

Step 6: Reinstall the Hardware

Once the paint is completely dry, carefully reinstall the door knobs and hardware. Use the photos you took during the removal process to guide you. Handle the painted hardware with care to avoid any chipping or scratching of the fresh paint.

Tips for Success:

• Always work in a well-ventilated area when using spray paint.
• Wear protective gloves and a mask during the painting process.
• Allow the paint to cure for a few days before using the door knobs extensively.
• If desired, apply a clear coat after the paint has dried to add extra protection and longevity.
