That's a great question! Mounting a sign on a public trash bin needs to be both effective and durable. Here’s what usually works best in an urban setting.
First, clean the surface thoroughly. Use a strong degreaser and let the bin dry completely. Any dirt or grease will prevent adhesion.
For most city bins, I recommend using a high-performance outdoor adhesive like VHB tape or a strong outdoor-rated adhesive gel. These create a permanent bond without drilling, which cities often prefer to avoid damaging bins. Apply the sign firmly, smoothing out any air bubbles.
If drilling is allowed, use stainless steel rivets or bolts with security heads to prevent tampering. Always add a waterproof sealant around the holes to stop rust.
Consider a protective laminate or sleeve over the printed sign. This protects it from weather, scratches, and graffiti. For cylindrical bins, a clear, flexible plastic sleeve that wraps around is ideal.
Finally, placement is key. Mount the sign at eye level on the side where people approach, using simple graphics and large text for quick understanding. Check it periodically for wear and tear.
The goal is a clear, long-lasting message that survives the elements and heavy use!
