A Squeegee is a handheld, flat-edged tool made of flexible plastic, rubber, or nylon used to apply pressure to self-adhesive vinyl, application tapes, and window films. Its primary function is to evacuate air from beneath the media and create a uniform, permanent bond between the adhesive and the substrate.

Why It Matters: Impact and Use
In the world of signage and vehicle graphics, the squeegee is the most essential manual tool. Proper technique and tool selection are vital for E-E-A-T (Expertise, Authoritativeness, and Trustworthiness), as poor application leads to “bubbling,” “silvering,” or premature failure of the graphic.
- Ergonomics and Precision: Professional squeegees come in different “shore” ratings (hardness). A hard squeegee is best for flat surfaces like windows, while a flexible nylon squeegee is required for curved surfaces and vehicle contours to prevent “creasing” the film.
- Bubble-Free Application: The firm edge of the squeegee forces air pockets out to the edges of the vinyl. Without it, trapped air expands with heat, causing unsightly bubbles that can ruin the CTR (Color Transfer Rate) of your visual branding.
- Protecting the Graphic (Felt Edges): Many professional squeegees feature a “buffer” or a layer of Soft Flock (Felt). This allows the installer to apply high pressure to sensitive lettering and digital prints without scratching the protective laminate or the ink layer.
- Transferring Lettering: When using Application Tape to move cut-vinyl lettering from its backing paper to a window or vehicle, the squeegee is used to “burnish” the tape onto the vinyl, ensuring the letters lift cleanly and stay aligned.

Comparison: Squeegee Types & Use Cases
| Squeegee Type | Material | Best For |
| Standard Plastic | Rigid Polyethylene | High-tack application tapes and industrial marking. |
| Felt-Edge | Plastic with Felt Buffer | Printed vinyl, car wraps, and delicate lettering. |
| Nylon / Flexible | Soft Nylon | Contoured surfaces, rivets, and vehicle body lines. |
| Rubber / Wet | Soft Rubber | Window tinting and “wet-method” vinyl application. |
Frequently Asked Questions
Why should I use a felt-edge squeegee instead of a regular one?
A felt-edge squeegee acts as a cushion. It prevents the hard plastic from scratching the surface of the vinyl or digital print, which is especially important for glossy films or unlaminated graphics.
What is the best technique for using a squeegee?
Always work from the center outward using overlapping strokes. Hold the squeegee at a 45-degree angle to the surface to ensure that air is pushed in front of the blade rather than trapped underneath it.
Can I use a credit card as a substitute for a squeegee?
While possible for very small stickers, it is not recommended for professional work. Credit cards are too rigid and have sharp edges that can easily scratch the vinyl or snap under the pressure required for a permanent bond.
