Common mistakes when applying start numbers and how to avoid them

Applying bib numbers may seem simple, but many small mistakes can lead to poor results, shortened durability or even problems with the competition rules. Here we go over the most common mistakes and how you can avoid them for a professional and long-lasting result.

1. Poor surface preparation

A dirty or oily surface is one of the most common reasons why race numbers do not stick properly. Decals applied to such surfaces tend to peel off or bubble.

• Wash the surface with warm water and detergent before application.
• Use alcohol-based cleaners to remove grease and oil.
• Ensure the surface is completely dry before applying.

2. Wrong placement

The placement of the start number is crucial for both visibility and regulations. Misplaced numbers can cause problems during competitions.

• Use masking tape to mark the position before application.
• Check the competition rules carefully to ensure that the numbers are placed correctly. For rallies and folk races, the rules may vary between organizers.

3. Application at the wrong temperature

Cold or extreme heat can affect how well the decal sticks. If the temperature is incorrect, the adhesive can weaken or set too quickly.

• Apply in temperatures between 15–25 °C for best results.
• Avoid applying outdoors on cold or very hot days.

4. Using the wrong materials

Not all decals are created equal. Cheap materials can fade, crack, or come off during competition.

• Invest in high-quality products designed for motorsport.
• Check specifications to ensure the material can withstand mud, water and high speeds.

5. Common problems with air bubbles

Air bubbles can ruin the decal and affect its durability. They are one of the most common problems during application.

• Use a squeegee to press out bubbles from the center outwards.
• If bubbles appear, use a needle to poke holes and press out the air.

6. Lack of maintenance

Even after the bib is in place, lack of maintenance can shorten its lifespan. Exposure to washing, weather and wear requires proper care.

• Avoid washing the vehicle within 24 hours of application.
• Inspect the decals regularly to detect and repair damage.
