Interior door knobs or exterior ones can affect how your doors appear. There are situations where you might want to give your door knobs a new look or make them match your doors.
What is the best way of achieving this? Should you buy new ones, or can you spray paint door knobs?
In this article, I will outline why spray painting your door knobs is a better and more economical decision than buying new ones. I’ll also outline how to spray paint door knobs to get a professional finish, even if you have never done it before.
So, let’s get right into it!
Can You Spray Paint Door Knobs
Yes, you can spray paint door knobs. You can use most of the spray paints on door knobs and hardware; however, we recommend you use metallic, enamel, chrome, or universal spray paints. Also, you must clean and prime before spraying 2 or 3 thin coats to get the best finish.
Can You Spray Paint Brass Door Handles?
Yes, spray paint can be used on brass door handles. To ensure your painted brass or metal door knobs last, prep them before applying the paint. Using a quality metal primer and enamel spray paint will improve the paint job’s durability.
Will Spray Paint Work on Door Knobs?
Yes, spray paint will work on door knobs and adhere well if you use the right spray paint for the type of interior door hardware or exterior in question.
Proper prepping, priming, and spray paint application will help the paint correctly stick to your door knobs and last.
If you do not properly prep the door knobs or use a quality primer and spray paint, your paint job will not last.
Also, your spray-painted door knobs will not have your desired final finish.
Spray Painting Door Knobs vs Buying New Ones?
Spray painting door knobs is much more economical than buying new ones.
Let me give you an example of my previous project to understand better how economical painting can be.
My house has 7 doors meaning I needed 14 door knobs. The cheapest door knobs I could find at Lowe’s cost $115 – that’s a pack of 5 door knobs with all the hardware needed to install them.
I would have had to buy 3 packs for $345 for my project.
Going with the spray-painting route, I bought a high-quality enamel spray paint for $12, a primer for $15, and a can of top coat for $6. The total was $33.
Opting to spray paint meant I saved more than $300.
As you can see, I saved more than 90% by spray painting rather than buying new door knobs.
It is important to note that even if I had decided to buy door knobs mentioned, I would still have to paint them since they did not match my doors.
What to Look for in A Door Knob Spray Paint?
Some of the things you should look for in a door knob spray paint include:
1. Type of paint
There are different types of spray paint, and choosing the right one to spray your door knobs is an important decision. Most universal, chrome, metal, and solvent-based spray paints can be used on door knobs.
Coverage area is an important factor when choosing any spray paint. Choosing a spray paint with a larger coverage means you will have to spend less on paint, especially if you intend to paint many door knobs.
Different types of paint have different durability. Therefore, picking a paint with high adhesion power that can withstand frequent handling and weathering is important.
How to Spray Paint Door Knobs: Step-by-Step Guide
Supplies You Will Need
- Drop cloth or newspapers
- Paint stripper or remover
- Tack cloth
- Warm, soapy water and degreaser (if required)
- Sandpapers (180,200, and 240 grit)
- Paint, primer, and top coat
- Table or crate
Step 1: Prepping the Work Area
Prepping your work area is essential to ensuring you have an easier and more seamless experience spray painting your door knobs.
Check to make sure that all the supplies you will require are close by. Your work area should have proper ventilation and enough room for spray painting.
Remember to ensure no children and pets enter your work area to avoid the harmful fumes from the spray paint.
Step 2: Removing the Door Knobs
Use an appropriate screwdriver to remove the screws from your door knob.
Remove one screw at a time while remaining careful not to chip the screw head or scratch the knob.
Place the screw in a separate area – you can use a small container.
Repeat this process until you have removed all screws and door knob hardware.
Please note that you can still paint your knobs without removing them.
This is not recommended since you will not be able to spray paint the entirety of the knobs’ surfaces, and you may paint other areas of the door that you did not intend.
Nonetheless, if you are determined to paint without removing the knobs, ensure you properly tape up the surrounding areas to avoid getting paint on them.
Step 3: Removing the Old Paint on the Door Knob
When spray painting old door knobs, chances are they were previously painted.
If so, I recommend removing the old paint before moving forward.
You can use sanding paper, paint stripper, or remover to remove old paint from your door knobs and hardware.
If using sandpaper:
- Lightly sand the old door knob paint job using 180-grit sandpaper. You may have to do two rounds of sanding using this sandpaper.
Follow that up by sanding using 200-grit paper. Ensure all the old paint has been removed from the knob and that it is left bare.
If you choose to use a paint remover or stripper:
- Pour the solution on a tuck cloth.
- Using your dump cloth, carefully wipe and apply the remover on the door knobs.
- Give the solution time to soak into the old paint- 10 to 30 minutes should be okay.
- Wipe the paint away using a drop cloth until all the paint is gone.
- Remember to remove the paint from the screws as well. With the screws, I would recommend using a painting removing or stripping solvent.
- Pour a small quantity of the paint stripper or remover into a small container and put the screws inside the solution.
- Give it 10 to 20 minutes, remove the screws, and place them on a drop cloth.
Wrap them in the cloth and rub the cloth against them so you remove the solution and paint.
Repeat the process if needed until you remove the old paint completely.
Side Note: If your door knobs were not previously painted, then skip this step.
Step 4: Cleaning the Knobs
Ensure you thoroughly clean the door knobs and hardware.
You may do this using a drop or tack cloth. You may use a degreaser or warm soapy water if there are any stubborn stains or oil residues on the knobs.
After cleaning, wipe the wetness and dry the knobs before moving to the next step.
Step 5: Sanding the Door Knobs
This is one of the mandatory steps, and you should never skip it.
It does not matter whether you are working with new, old, painted, or unpainted door knobs; sanding is necessary.
Sanding allows you to rough the surface of the door knobs so that it has teeth for the primer to adhere to during application.
The paint might still adhere to the door knobs without sanding, but it won’t do so as well as when their surfaces have been sanded.
When sanding, use 240-grit sandpaper and sand using a back-and-forth motion across the entire surface of the door knobs.
Remember to avoid using too much wrist pressure to avoid creating scratches and chips on the Door knobs. If you do so, you may not be able to conceal by spraying the primer and paint.
Also, avoid sanding in a circular motion, as this will create sanding marks that will be visible after paint.
After this second sanding step, you should use a drop cloth to wipe the door knobs.
If you feel it is necessary, you may use a damp cloth to remove any remaining sanding residue before air drying the door knobs.
Step 6: Applying the Primer
- On top of a table or a few crates, spread the drop cloth or newspapers. Do this in a way that will cover the entire surface of the crate or table.
- Place all the door knobs and hardware on top of the drop cloth or newspaper’s spreading.
- Ensure that the knobs are spread far apart to give you enough room to spray each one without interfering with others.
- No, turn the knobs outside down in preparation for spraying the primer.
- Shake the primer spray for 2 minutes to create a uniform mixture.
- Hold the can about 8 inches from each knob and spray a thin coat of the primer to the bottom surface (surface that will be in direct contact with the door).
- Give the knobs enough time to dry to the touch before turning them the other way around, spraying their faces (visible surfaces).
- Do the same with screws, starting with onside before rolling them and priming the remaining side.
Give the door knobs and screws enough time for the first coat of primer to dry. In most cases, several hours should be okay.
If required, you can repeat the process by applying the second coat of primer and letting everything dry again.
Step 7: Spray Painting the Door Knob
You are now ready to apply the spray paint once the second coat of primer is dry.
When applying the first coat of spray paint, make sure you follow all the same instructions outlined in the step above.
Let the paint dry before applying a second coat.
Here are a few spray tips to help achieve better results:
- Hold the spray can far enough to avoid splattering– a distance of 8 to 12 inches is fine.
- When you apply primer, paint, or top coat, it is better to apply multiple thin coats than a single thick one. This will quicken the dry time between the coats and give a better finish.
- Allow each coat of paint to dry before applying the next one.
- Spread the paint evenly across the surface to form a uniform coat of paint.
After applying the spray paint, give the door knobs enough time to dry before moving on to the next step.
Step 8: Applying a Top Coat
While this step is not mandatory, I recommend it as it provides an extra layer of protection for your paint job and door knobs.
Apply a thin, even layer of a clear top coat on all the door knobs plus the screws.
Let them dry, and then apply a second coat.
Step 9: Letting Everything Cure Before Reinstalling the Door Handles
Letting everything cure ensures you will not rub off or scratch the paint.
After all the painting has been done, let the door knobs and screws sit for 2 to 3 days – this is enough time for most spray paint to cure.
After this, you can safely reinstall the Door knobs and hardware.
