What to do if Spray Cans Leak or Sputter Paint
When using spray paint, it’s common to encounter clogging or inconsistent spray patterns. Here are some tried-and-true tips to help you get the best results:
Start with a Fat Cap
Always begin spraying with the fattest cap you have. This helps clear out any small chunks or clogs that may have settled in the can during storage. Many Ironlak cans come with fat caps like Pink Dots or Widow Makers, which are ideal for this.
Understand the Cap Notch
If the can won’t spray, check the stem of the cap. You’ll notice a notch—wider notches allow more paint to flow. If your cap is clogged, you can carefully widen the notch with a razor blade to help paint clogs pass through. After this, switch back to your preferred caps for normal use.
Shake Thoroughly
Shake the can vigorously—don’t hold back. A well-shaken can make a huge difference in paint consistency and flow.
Clean Your Caps
Dirty caps are a leading cause of clogs. Soak them in acetone after use to keep them clean. Alternatively, Montana offers acetone cleaning cans—just attach a used cap and spray twice to clean it. This is a smart investment for frequent painters.
Proper Cap Placement
Ensure the cap is securely attached. Some caps require extra pressure to activate properly—press down firmly.
Temperature Matters
The temperature affects how paint sprays. In hot conditions, paint flows faster; in cold conditions, it sprays slower. Adjust your technique accordingly.
Avoid Stop-Start Spraying
Frequent short bursts can lead to more clogging. Instead, try spraying continuously for a few seconds to clear the nozzle and lines.
Clear the Nozzle After Use
Turn the can upside down and spray until only air comes out. This clears the nozzle and prevents clogs from drying paint.
Warm Up the Cans
Before spraying, place your cans in a bucket of hot water for a few minutes. This helps thin the paint slightly, making it spray more smoothly. Be sure to still shake for the full 3 minutes.
Choose the Right Paint for Your Needs
High-pressure brands like Ironlak can be harder to control. If you’re looking for more precision and less splatter, consider switching to a low-pressure brand like Montana 94 (MTN94), which many artists find easier to handle.
Bonus Tip:
White and yellow paints are more prone to clogging and splattering. Clearing the lines before serious use helps minimize issues with these colours.
By following these tips, you can avoid frustration and keep your spray sessions running smoothly. Good luck, and happy painting!
