How to apply start numbers and backgrounds like a pro

Applying race numbers and backgrounds correctly is crucial to ensuring a professional finish and that the decals stay in place throughout the race. With the right technique and preparation, you can avoid problems like air bubbles and misplacement.

1. Prepare the surface carefully

Before you start applying, the surface must be clean and dry. Dirt, grease or moisture can impair the adhesion of the adhesive.

• Wash the surface with warm water and a mild detergent.
• Use isopropanol to remove grease and other residue.
• Dry the surface completely with a lint-free cloth.

2. Position the decal correctly

The placement is crucial for a neat and rule-approved result.

• Use masking tape as a guide to ensure the decal is straight.
• Make sure the numbers and background follow the competition rules for your discipline. Read more about our complete bib number package here .

3. Avoid air bubbles when applying

Air bubbles are a common problem, but they can be avoided with the right technique.

• Start from the center of the decal and work your way outwards using a squeegee.
• If bubbles still appear, use a needle to poke holes and press out the air.

• Avoid washing the vehicle within 24 hours after application.

5. Common mistakes and how to avoid them
