Get Better Control With a Spray Can Trigger Handle
Applying a finish from a spray can is one of the quickest and easiest ways to protect a woodworking project. Aerosol finishes are especially handy for small projects, intricate parts, and surfaces that would be difficult to coat evenly with a brush.
But spray cans have a couple of drawbacks. Holding down the small nozzle can become uncomfortable, and it's easy to get finish on your finger. It's also possible to pick up the can with the nozzle pointing in the wrong direction and accidentally spray somewhere you didn't intend.
Fortunately, there's an inexpensive accessory that makes spray finishing easier. A spray can trigger handle snaps onto the top of an aerosol can, giving you a comfortable grip and better control over the spray.
In the video, we'll show you how this handy accessory works and why it's worth keeping with your finishing supplies.
Why Use a Spray Can Trigger Handle?
Aerosol finishes are convenient because they don't require brushes, spray guns, or complicated equipment. Just shake the can according to the manufacturer's directions, aim the nozzle, and apply the finish.
The challenge is controlling the spray while holding the can comfortably.
Most aerosol cans use a small push-button nozzle that you operate with one finger. During longer finishing sessions, this can become uncomfortable. And because your finger is positioned directly above the nozzle, it's easy to end up with finish on your hand.
A spray can trigger attachment provides a simple solution.
Instead of pressing the nozzle directly, you operate the can with a two-finger trigger and a pistol-style handle. This gives you a more comfortable grip and makes it easier to control when the finish is applied.
A Simple Accessory for Easier Spray Finishing
The spray can handle shown in the video is a low-cost accessory available at many hardware stores.
It features a comfortable handle, a two-finger trigger, and a locking mechanism that helps prevent accidental spraying.
The handle allows you to hold the can securely while using your fingers to operate the trigger.
This makes it easier to maintain a consistent grip as you move the can across a workpiece.
The locking feature is another useful detail. It helps prevent the trigger from being activated unintentionally while you're positioning or handling the can.
How to Attach a Trigger Handle to a Spray Can
Installing the handle takes only a few seconds.
Step 1: Position the Handle
Start by making sure the spray nozzle is pointed in the intended direction.
Position the trigger handle over the top of the aerosol can, aligning its mechanism with the spray nozzle.
Step 2: Snap the Handle Into Place
Press the handle onto the can until it seats securely.
Check that the trigger mechanism is properly aligned with the nozzle and that the handle doesn't shift or wobble.
Step 3: Secure the Locking Ring
Turn the locking ring to secure the attachment, following the handle manufacturer's instructions.
Before spraying, check that the trigger operates properly and that the nozzle is pointed away from you.
Using the Trigger Handle to Apply a Finish
With the handle attached, you're ready to apply the finish.
Hold the can by the grip and use the two-finger trigger to control the spray. This keeps your hand in a more comfortable position and away from the nozzle.
Move the can smoothly across the workpiece, maintaining the distance and application technique recommended on the finish label.
Start spraying just before reaching the workpiece and release the trigger after passing the opposite edge. This helps reduce heavy buildup at the beginning and end of each pass.
Overlap successive passes slightly to maintain even coverage.
The trigger handle doesn't change the spray pattern or the finish itself, but it can make the can easier to hold and operate throughout the finishing process.
Tips for Better Aerosol Finishing
A trigger handle can make spray finishing more convenient, but good technique is still important.
- Check compatibility. Make sure the trigger attachment fits the aerosol can and operates the nozzle correctly.
- Keep the nozzle aligned. Check the spray direction before pulling the trigger.
- Apply light coats. Several thin coats generally provide better control than one heavy application.
- Maintain a consistent distance. Follow the finish manufacturer's recommended spraying distance.
- Keep the can moving. Smooth, overlapping passes help prevent runs and uneven coverage.
- Use the safety lock. Engage the locking mechanism when the handle isn't in use.
- Work safely. Spray only in an appropriately ventilated area, away from ignition sources, and follow the product label for respiratory and other protective equipment.
A Handy Addition to Your Finishing Supplies
Sometimes a small accessory can make a familiar task noticeably easier.
A spray can trigger handle is a good example. It provides a more comfortable grip, keeps your finger away from the spray nozzle, and gives you convenient trigger control when applying aerosol finishes.
Best of all, it's inexpensive, easy to attach, and takes up very little room in your finishing cabinet.
The next time you reach for a spray can to finish a woodworking project, give one of these trigger handles a try. It's a simple upgrade that can make an already convenient finishing method even easier.
