How to Choose the Right Spray Nozzle for Your Painting Project
Whether you're tackling a fence, a deck, or your living room wall, the right spray nozzle can make all the difference. At AxiaTool, we know how overwhelming it can be to choose from various nozzle sizes, spray patterns, and materials — so here’s a clear, beginner-friendly guide to help you paint like a pro.
🎯 Why Nozzle Choice Matters
Your spray nozzle determines:
-
✅ Paint flow rate
-
✅ Spray pattern width
-
✅ Precision and coverage
-
✅ Finish quality
Wrong nozzle? Expect drips, uneven coats, and wasted paint.
Right nozzle? Smooth, professional, efficient results.
🧠 Understanding Nozzle Sizes
Spray nozzles are usually labeled with three-digit codes, like 515 or 313. Here's how to read them:
| Example | Fan Width (First Digit × 2) | Orifice Size (Last Two Digits) | Best For |
|---|---|---|---|
| 313 | 6 inches | 0.013 inch | Thin paints, trim |
| 515 | 10 inches | 0.015 inch | Latex paint, walls |
| 619 | 12 inches | 0.019 inch | Thick coatings, fences |
Pro Tip: The higher the second two digits, the thicker the paint it can handle.
🎨 Choose by Project Type
| Project | Recommended Nozzle |
|---|---|
| Indoor Walls | 515, 517 |
| Trim & Furniture | 313, 311 |
| Outdoor Fencing | 619, 517 |
| Deck & Patio | 517, 519 |
| Cabinets | 311, 313 |
🔄 Fan Shape: Horizontal vs. Vertical
Most nozzles can be rotated to control the spray direction:
-
🔄 Horizontal for tall areas (like walls)
-
🔄 Vertical for wide surfaces (like fences, decks)
💡 Bonus Tips
-
Replace worn nozzles for better results.
-
Always strain paint to avoid clogging.
-
Test spray pattern on cardboard before starting.

The right nozzle = less waste, better coverage, and pro-level results.
