1. Gather Your Tools

Before you begin, make sure you have all the necessary tools:

  • Squeegee or credit card

  • Clean cloth

  • Measuring tape

  • Level

  • Painter's tape

  • Cleaning solution

2. Prepare Your Surface

  • Clean the wall thoroughly with mild soap and water

  • Remove any dust or debris

  • Allow the surface to dry completely

  • For best results, avoid applying decals to freshly painted walls (wait at least 2 weeks)

3. Plan Your Placement

  • Use a measuring tape and level to mark your desired position

  • Create reference points with painter's tape

  • Step back and verify the placement looks correct from different angles

4. Check Your Room Temperature

  • Ideal application temperature is between 65-75°F (18-24°C)

  • Avoid applying decals in extremely hot or cold conditions

  • Keep away from direct sunlight during application

5. Start With a Test Corner

  • Begin peeling from one corner

  • Test a small section first

  • If the decal doesn't stick properly, the wall might need additional cleaning

6. Use the Hinge Method

  • Position your decal and secure the top with painter's tape

  • This creates a hinge that ensures proper alignment

  • Peel away the backing gradually while working downward

7. Apply With Proper Technique

  • Work from the center outward

  • Use smooth, firm strokes with your squeegee

  • Keep the application angle consistent

  • Move in small sections at a time

8. Remove Bubbles Immediately

  • If you spot a bubble, lift the section gently

  • Reapply using firm pressure

  • Use your squeegee to push air bubbles toward the nearest edge

9. Pay Special Attention to Details

  • Take extra care with intricate designs

  • Work slowly around letters and small elements

  • Don't rush the process – patience is key

10. Final Smoothing

  • Once the entire decal is applied, go over the entire surface again

  • Use firm, overlapping strokes

  • Pay special attention to edges and corners

  • Remove the transfer tape at a 180-degree angle

Pro Tips:

  • If you're working with a large decal, ask a friend to help

  • For textured walls, you may need to apply extra pressure

  • Keep the room free from drafts during application

  • Wait 24-48 hours before touching or cleaning the decal
