Line Marking Spray Guns & Gun Spares

Upgrading to professional spray guns is one of the best moves you can make for quality and comfort. The biggest benefit is the ergonomic design. A professional gun, like the Graco SG3, is built to reduce hand fatigue with a lighter trigger pull and a more comfortable handle. When you're spending hours on a big job, this makes a massive difference, allowing you to work longer and with greater control.

Another huge benefit is the build quality and performance. Professional spray guns are made with more durable components, meaning they can handle higher pressures and the daily wear and tear of a worksite. They also feature better fluid passages, which ensures a more consistent flow of paint to the tip for a sharper, cleaner line every single time. It's all about getting a superior finish with less effort

The right gun makes all the difference! When choosing from the various spray guns available, the main thing to consider is the type of work you do. For standard line marking in car parks or on factory floors, a gun like the Graco SG3 is a fantastic all-rounder. It's durable, comfortable, and delivers a great finish. It comes standard on many LineLazer machines for a good reason.

If you're doing a lot of stencil work or detailed markings, you should look for a gun with a lighter trigger pull and possibly a shorter barrel for better control. For maximum comfort and performance on long jobs, upgrading to a premium model like the Contractor PC gun is a game-changer. It features an ultra-light trigger and customisable handle, which dramatically reduces fatigue. The key is to match the gun's features to your main tasks

While many standard airless spray guns can be used on a line marker, there are a few key differences. Specialised line marking guns are often designed with a shorter barrel and a more compact profile. This brings the spray tip closer to the ground, which can help in creating sharper, more defined lines, especially when doing detailed work like stencilling.

The biggest difference, however, often comes down to the trigger lock mechanism. Standard spray guns have a trigger lock to prevent accidental spraying. On a line marking machine, the gun is often activated by a cable system connected to a lever on the handlebars. Line marking-specific guns are designed to work seamlessly with this setup. While a standard gun will work perfectly well, a gun designed for line marking can offer that extra bit of ergonomic advantage and convenience for the operator.

Knowing the warning signs can save you from a bad finish on a job! The most obvious sign is when your spray guns start "spitting" paint instead of producing a consistent, even fan pattern. This usually means there's a blockage or, more likely, that the internal seals or the needle are worn out. Another clear signal is a gun that leaks paint from the handle or trigger, which points to worn seals that need immediate attention.

You should also look out for a trigger that feels "mushy," sticks, or is hard to pull. This indicates a problem with the trigger mechanism or a build-up of dried paint internally. While many of these issues can be solved with a good clean and a simple rebuild using a gun repair kit, sometimes it's more cost-effective to replace the gun entirely, especially if the body is damaged or heavily worn. A new gun is a quick way to restore perfect performance. If you think it's time for a fix, check out our Line Marking Pumps & Repair Kits.
