The wet method is one of the most effective techniques for applying decals to bikes, whether you're customizing a road bike, dirt bike, or motorcycle. In this guide, you'll learn step-by-step how to install bike decals using the wet method — perfect for large or complex vinyl graphics.
Why Use the Wet Method for Bike Decal Installation?

Tools & Materials You’ll Need
-
Spray bottle (filled with water + a few drops of dish soap)
-
Squeegee or plastic card (wrapped in microfiber)
-
Rubbing alcohol or plastic-safe cleaner
-
Clean microfiber cloths
-
Heat gun or hair dryer (optional for final setting)
-
Razor blade (optional for trimming edges)
Step 1: Prep the Surface
Start by cleaning the area where you’ll apply the decal. Use rubbing alcohol or a plastic-safe cleaner to remove dirt, grease, and oils. A clean surface ensures strong adhesion and reduces the risk of peeling later.
🚫 Avoid using wax-based cleaners — they prevent the decal from sticking properly.
Step 2: Mix Your Wet Application Solution
In a spray bottle, mix:
-
Water (about 95%)
-
Dish soap (just a few drops)
This soapy water solution lets you slide and reposition the decal before it sticks permanently.
Step 3: Spray the Surface & the Adhesive Side
Generously spray both the bike surface and the adhesive side of the decal with the solution. Don’t worry — the decal won't stick immediately, giving you time to position it just right.
Step 4: Place and Position the Decal
Carefully apply the decal to the wet surface. Because of the soapy solution, you can slide the sticker into the exact position you want. Take your time to align it properly.
Step 5: Squeegee Out the Water & Air
Using a plastic squeegee or wrapped card, gently press from the center outward to remove water and air bubbles. Work slowly and firmly. Wipe away excess liquid with a microfiber cloth as you go.
💡 Pro Tip: Use light pressure at first to avoid shifting the decal, then increase pressure to push out all water.
Step 6: Let It Dry & Set
Allow the decal to dry for 24–48 hours. Keep the bike indoors if possible. The adhesive will bond as the moisture evaporates.
Optional: Use a heat gun or hair dryer on low to help dry the decal faster and soften it around curves or edges.
Step 7: Final Inspection
After drying, check for any remaining bubbles or edges that haven’t stuck. Small bubbles can be popped with a pin and smoothed out. Press down edges with your finger or reheat gently if needed.
