The size of an airless spray tip used to paint door frames depends on the type and quality of the paint being sprayed. A high-quality, water-based paint requires a smaller nozzle than a thicker oil-based product such as latex or enamel.
The difference in the thickness causes different types of paints to require different sized nozzles for optimal performance. This post will discuss how one can determine what size airless spray tip they need based on their product choice and how it affects price and longevity.
To determine what type of airless spray tip you need, you’ll first want to figure out if your project requires an oil-based or water-based paint before continuing with this.

1.What is the size of an airless spray tip that is used to paint door frames?
In the industry, airless spray tips can come in various sizes that could be used for many different things. It is hard to pinpoint any specific size and tell you which one would be best suited for painting door frames.
Airless spray tips are measured by their outside diameter (OD) and tube length (TL). The only way to accurately determine what size you need is to check your equipment manufacturer’s specifications.
The most common airless spray tip size found on door frame painting equipment is a 3/8″ OD x 18″ TL. This particular spray tip can also be referred to as a #10 spray tip, which falls under the category of suggestions with a .023-inch ID tube.
The two main sizes of tips commonly used are:
#15 – or .029″ ID tube (also known as 3/16″) – these are suited for use on light finish work and provide reasonable overspray control due to their small orifice size, but they do not atomize paint well because of their large diameter.
#30 – or .035″ ID tube (also known as 1/4″) – these produce a very spray pattern but typically cover less area than a #15 or 3/8″ tip. They are most commonly used on heavy finish work that can handle the amount of overspray and can be atomized into finer droplets.
Their “series can also classify them.” In general, the smaller the number in front of the “series” designation, the larger and faster-atomizing they typically are:
#00 – these have a more comprehensive ID tube than any other conventional tip at .040″ (1.02 mm) – these are used for priming as they atomize moderately well and cover large areas relatively fast; however, due to their poor overspray control and extensive spray pattern.
2.Why it’s essential to use a smaller nozzle when painting door frames
When you are painting door frames, it is essential to use a spray tip that has a smaller nozzle. A much larger nozzle will produce heavier droplets on the surface of your work and look more like spatter or spatters. Also, when using these types of tips, there may be areas where this heavier paint accumulates and makes the surrounding area darker than the rest.
#15 – or .029″ ID tube (also known as 3/16″) – these are suited for use on light finish work and provide reasonable overspray control due to their small orifice size; however, they do not atomize paint well because of their large diameter.
They can also be classified by their “series.” In general, the smaller the number in front of the “series” designation, the larger and faster-atomizing they typically are:
#10 – or .031″ ID tube (also known as 1/8″) – these have a smaller spray pattern than the #15 tips and are used for painting tight areas, such as door frames. They typically provide excellent overspray control because of their small spray pattern and are capable of being atomized into finer droplets; however, they have a large diameter that can make it challenging to paint in corners.
Another reason to use smaller nozzles when painting door frames is that you will be able to achieve better blending at the corner joints between panels using less-open nozzles. This will result in having a smoother transition from one color to another without too many visible changes occurring on your project.
3.Ways you can avoid overspray and get better coverage on your door frame
There are two things you can do to help keep overspray to a minimum when painting door frames. One uses a smaller spray tip for your equipment, and the other is to adjust your spraying technique.
Using a smaller tip will allow you to get into the corners and cut-outs more effectively, which results in better coverage. It also helps prevent heavy deposits of paint, which reduces the appearance of blotchy spots. And by using your equipment correctly, you will be able to avoid dusting over previously painted areas that are still wet or tacky and help provide a smoother transition between colors.
If desired, one can use a #0 or #00 spray tip for priming door frames due to the wide range of their spray patterns; however, most professionals prefer to use an even broader spray pattern when priming because it is easier to cover large areas with these tips.
Depending on which size tip you opt to use, these shooting techniques will help ensure better coverage:
If you decide to use a smaller nozzle when painting door frames, make sure not to change equipment too often during your project; otherwise, it may create uneven spraying patterns, which result in blotchy spots. When using your gear, consider that smaller spray tips do not provide reasonable overspray control because they atomize paint too fast and create heavier droplets on the surface.
Therefore, when spraying near previously painted areas (preferably while both surfaces are still wet), you will want to use a broader spray pattern; this will help reduce the amount of paint being deposited into these areas, reducing the appearance of visible brush strokes or lines.
If you wish to emphasize specific features such as doors or archways on your project with an accent color, be sure to position yourself so that you can achieve better coverage by holding your gun at different angles.
4.Tips for getting a professional-looking, uniform finish with this technique
One of many people’s most significant problems when painting door frames is not applying enough products to achieve a professional-looking finish. When doing this, keep in mind that paint needs to be thick enough to adhere correctly and consistently but thin sufficient for good flow into all types of joints.
To get a professional-looking finish, you also want to be sure that the paint frame is smooth and free of all wrinkles by applying additional coats one at a time.
If your project requires special touches such as wood grain texture or multiple colors on your door frame, you may find it beneficial to use an airbrush instead. This will make it much easier to achieve smoother transitions between different shades and keep things looking very consistent with little effort on your part.
Typically, this painting technique is considered a drywall texture technique, which means you will need to let it sit for at least 24 hours. For areas that are not primed beforehand, it may be necessary to apply an additional coat; make sure to wait approximately 4-6 hours before doing so.
5.Which types of paints are best suited for spraying onto surfaces like doors or walls?
The right type of paint is critical for achieving a professional-looking finish. The best colors to use are high-quality acrylics and oils, which can both be sprayed without any additional prep work or primers.
- Acrylic Paints – These are typically considered the most forgiving when used with this painting technique. Any brand will work, as long as it is a high-quality product, especially if you plan on using multiple colors with this process; however, some acrylic paints tend to spray more evenly than others, so you may want to experiment with various options before deciding on one particular brand for your project.
- Oil Paints – Not all oil paints can be sprayed, but those that are formulated for spraying will often give a more natural-looking finish when used with this technique because of their thicker consistency; however, they may not spray as evenly, which is why you want to experiment with multiple brands before deciding on one particular product for your project.
6.What size tip should I use to spray trim?
- 6a. TIP SIZE FOR DOOR AND TRIM – T-111 (1/4 inch) -for painting wood surfaces such as doors, trim, baseboards, or other types of molding. T
- -111 is also an excellent general-purpose spray tip for spraying areas like ceilings, walls, and woodwork with a large variety of paints.
- 6b. TIP SIZE FOR METAL SURFACES – 2″ (2-1/4) -for painting metal surfaces such as steel or aluminum doors along with other types of metal trim or hardware on your project. This diameter will produce the smallest possible droplets, which makes it ideal for this type of application since it will help create a smoother finish that covers in fewer coats.
- 6c. TIP SIZE FOR GROUTING – 1/4″ (#1458) -this tiny spray tip can be used to paint grout between tiles.
- 6d. TIP SIZE FOR PAINTING BATHROOM AND KITCHEN CABINETS – 2″ (2-1/4) -this size tip will give much more control over where the paint gets spread on large flat surfaces such as kitchen cabinets and bathroom vanities; however, it may take longer to cover everything since more small droplets are being sprayed onto these surfaces than you would get from using a larger spray tip like the one recommended for T-111.
- 6e. TIP SIZE FOR PAINTING DOORS WITH STUCCO – 1/4″ (#1458) -using a very tiny spray tip like this one makes it easier to paint stucco without getting any of the plastic texture being picked up by the paint while you are spraying. This also works well for painting other types of uneven surfaces, including brick.
