What Is The Best Spray Tip For Trim?

It’s time to paint the trim. Unfortunately, you have no idea about the spray tip. Which is the best spray tip for trim? How can we choose one from tens of choices? 

Each tip size serves a specific purpose. It is OK if you do not know. We will give you comprehensive guidance about the best tip for trim work. Please read on to learn more!

What Is The Best Spray Tip For Trim?

The best spray tips for trim are 210 and 310. You can use 108 for a very limited fan width for stair railings. Consider the 510 if your baseboards are taller. 


You should choose a right spray tip for trim


For doors and trim, either a blue 311 tip or a green 310 tip would suffice. However, the green 310 is still more popular. The six-inch fan is large enough to completely cover most baseboards and door frames. This size is also suitable for spraying paint closet doors and downspouts.

Depending on the paint’s thickness, a bigger aperture may be appropriate to keep the paint from clogging the gun.

What Does The Tip Number Mean? 

Why do we use numbers to name the tips? It is because you can see the necessary information through these figures.

Each tip’s name often includes three numbers. These figures reveal two things: The first is the fan’s size; The second is the amount and fluidity of the product you may spray.


What do the numbers mean?

The first number indicates the fan’s size. To keep things easy, we use inches to measure and at a distance of 12 inches from your spray area. 

For example, you use tip 310. It means that if you spray at a distance of 12″, the tip will produce a 6″ fan.

Some broad tips contain four digits, such as 1221. As you can see, the spray pattern will be 24 inches wide.

Knowing this will help you figure out what size you need. If you are painting a frame, you may want a thin spray. On the other hand, you may need a bigger tip than if you paint the roof.

The final two numbers represent the orifice’s size in thousandths of an inch. The larger the number, the larger the hole through which the paint will flow. Using the previous examples, a 310 has a 0.010″ aperture.

How To Choose A Spray Tip? 

There are various spray tips. How can we know the best one for our job? Let us help you!

Check the technical information

The telemetry information on the product description should be your first port of call.

The majority of materials offered today must include relevant product knowledge and relevant specifications for appropriate uses.

The product technical spec sheets will include a section with suggested spray tip sizing.


Carefully check the tip information before buying it

Check the packaging

Some sprayer tips have clear applications. Some of them are extremely specialized for specific materials or work needs.

They also frequently specify on the box which uses are appropriate for that particular spray tip.

Tip table

The tip table includes tip number, orifice size, thermal diffusivity, and filter suggestions.

You can consult its recommendations to choose the proper tip size.

Paint requirements

Let’s take advantage of the tip numbers to find a suitable one for your job.

The first number shows you the filter output. Tip names starting with numbers 1, 2, or 3 may work well with narrow paint surfaces. Apply them for the trim, doors, or stair rails.

For indoor and outdoor walls, use the spray tip numbers beginning with number 5 or 6. 

A four-digit figure beginning with 12 denotes a large spray fan width. It is the best choice for building walls.

What about the last two numbers? They tell you the size of the borehole. Bigger borehole diameters are proper for materials with bigger objects or higher viscosity.

How To Spray The Trim? 

You may find it difficult to spray the trim because of its small area. The instruction below will assist you:

  • Step 1: Choose the proper spray tip for the paint you use and the material you spray. Make sure the tip’s hole does not surpass your sprayer’s max capacity.
  • Step 2: If you utilize paint from various containers, combine them in a bucket to guarantee a consistent hue. Pick the lowest pressure level. It allows you to retain a nice spray pattern while spraying the trim. Lowering the pressure gives you more control and a crisper finish.
  • Step 3: Spray the trim in wide, steady strokes with the tip around 12 inches away from the surface.


How to spray the trim

After spraying, cleaning the tip is necessary.

Between applications, place your sprayer in a basin of water.

Rinse completely before spraying the next day or completing the work. Then, clean with an egg-shaped bucket.

When the spray tip becomes clogged, you can use cleansing needles and brushes to unclog it.

When cleaning the sprayer, make sure to follow the proper pressure relief method.


So, you may decide which spray tip is the best for trim. There is a wide range of tips. They vary in size and use. However, once you know their functions, you can make up your mind and choose the most suitable one.
