In this article, we will discuss the tips and tricks on how to know what spray tip to use for your job.

What is a spray tip?

Before anything else, let's define what a spray tip is. A spray tip is a cylinder with a tiny nozzle at one end, which is attached to the spray gun. Far more than just nozzles, spray tips decide the quality of the coverage and how much paint goes on a surface. All spray tips are unique and designed for a specific task, which is why it is essential to understand the differences among them.

 

 

How to choose a spray tip

Choosing the right spray tip can be determined by a few factors. Firstly, determine the type of coating you will apply to the surface. This could be anything from latex to oil-based paints, enamels, or stains. Secondly, consider the surface you will be painting, which could vary from walls, cabinets, furniture, to automobiles. Lastly, the size of the spray gun and the pressure it can apply should also be considered.

Spray tip sizes

A spray tip's size is designated by a three-digit number, which determines how wide the fan pattern is and the amount of paint that comes out. The first number determines how many inches wide the fan spray pattern will be when the paint is sprayed from the gun. For instance, 315 means 3 inches wide fan pattern. In contrast, 517 means 5 inches wide fan pattern. The second and third numbers indicate the size of the hole at the spray tip's end. These numbers determine how much paint the spray gun will eject when the trigger is pushed. A 315 tip will deliver less paint than a 517 tip. Typically smaller tips are used for detailed work, while large tips are used for broad finishes.

Knowing your coating

Different coatings have varying types of thicknesses and colors, making it crucial to choose a spray tip that corresponds to the specific coating. For instance, if you plan on using a high viscosity coating like textured coatings or elastomerics, you might want to use a tip that has a larger size opening to prevent the blockage of the tip. Medium viscosities like latex or emulsion paints will generally work effectively with a smaller tip size, as a larger tip will most likely cause too much paint to be sprayed onto the surface, resulting in drips or runs. Knowing the thickness and color of the coating you intend to use can save time and money by choosing the appropriate spray tip.

Surface type

When it comes to painting surfaces, the texture of the surface should also be considered when choosing a spray tip. Paints and coatings have different thicknesses, so a bigger tip will permit more paint onto the surface, but the droplets will clump on the surface and create an inconsistent finish or drip. A smaller tip will generate a smoother, cleaner finish but will require multiple passes. A moderate surface texture works best with medium-sized tips and a smooth finish with tiny tips.

Closing thoughts

In conclusion, understanding what spray tip to use will always help in achieving a successful painting project. Remember that the correct tip will vary based on the coating type, application surface, and spray gun pressure. Don't settle for a subpar job by using a spray tip that doesn't match your particular project needs.
