Airless Gun Setup: Tips and Tricks for Perfect Application

The Airless gun is a powerful and versatile tool, but to get the most out of it, it is crucial to adjust its settings correctly.

Find out in this guide how to adjust the pressure, choose the appropriate nozzle, and prepare your equipment for professional results, whether you are located in Draguignan, Sainte-Maxime, or Saint-Raphaël.

Why is Airless Gun Adjustment Important?

An improperly adjusted gun can cause problems such as drips, uneven spraying, or wasted paint.

Here's why precise adjustment is essential:

1. Obtain a uniform result

A suitable setting guarantees uniform spraying, without streaks or differences in texture, for an aesthetic and professional result.

2. Reduce paint loss

By optimizing settings, you minimize paint overspray and avoid waste, which is especially important for large projects.

3. Preserve the device

Improper adjustments, such as excessive pressure, can cause accelerated wear on your Airless gun or damage parts.

Steps to Properly Set Up an Airless Gun

Here are the detailed steps to adjust your Airless gun and achieve perfect application.

1. Choose the right nozzle

Nozzle selection is crucial because it determines the width of the spray and the flow of paint.

Each nozzle is marked with a three-digit code (example: 517).

How to interpret the nozzle code:

• First digit:

Indicates the width of the jet. Multiply this number by 5 to obtain the width in cm at a distance of 30 cm (example: 5 → 25 cm).

• Last two digits:

Indicate the diameter of the hole in thousandths of an inch (example: 17 → 0.017 inch).

Localized example:

To paint a wall in Saint-Raphaël, a 515 type nozzle was used for a quick application with a smooth finish.

2. Adjust the pressure

The pressure should be adjusted according to the type of paint and the surface to be covered.

Too high a pressure can create mist and drips, while too low a pressure can cause uneven spraying.

Steps to adjust pressure:

1. Start with low pressure:

Set your device to minimum pressure to avoid splashing.

2. Increase gradually: Increase the pressure until you obtain an even spray, without streaks or missed areas.

3. Test before painting:

Test on a piece of cardboard to check the quality of the jet.

3. Check the spray distance

The optimal distance between the gun and the surface is usually 25 to 30 cm.

Too short a distance can cause drips, while too long a distance can cause paint to scatter.

Practical tip:

Maintain a constant 90° angle to the surface for even coverage.

4. Adjust the jet width

Some Airless guns allow you to adjust the spray width directly on the nozzle.

A narrow width is ideal for details, while a wide width is suitable for large areas.

5. Adjust the paint flow

The paint flow can be adjusted to control the amount of product applied.

Too high a flow rate can result in drips, while too low a flow rate may require multiple passes.

Tips for optimizing the adjustment of your Airless gun

Here are some practical tips to maximize the efficiency of your device:

1. Always test before you start

Test on an inconspicuous surface or piece of cardboard to check settings before painting.

2. Adapt the nozzle to the type of paint

Use specific nozzles for thick paints (e.g. facades or coatings) and finer nozzles for stains or varnishes.

3. Clean the nozzle regularly

A clogged nozzle can affect spray quality.

Clean it after each use to avoid problems.

FAQ: Your questions about adjusting an Airless gun

1. What pressure should I choose for an Airless gun?

The optimum pressure varies between 150 and 250 bars, depending on the type of paint and the surface.

Always start with a low pressure and adjust it gradually.

2. What nozzle should I use to paint walls?

A 515 type nozzle is ideal for painting interior walls with acrylic or glycero paint.

3. How to avoid drips with an Airless gun?

Maintain a constant distance of 25 to 30 cm, use adequate pressure and apply thin coats.

Conclusion: Optimal setting for professional results

A properly adjusted Airless gun is the key to fast, even paint application.

By following the steps and tips in this guide, you will achieve impeccable results while preserving your equipment.
