UV, sun and how long stickers last outside

Sunlight is the number one enemy of a sticker. The ultraviolet part of sunlight breaks down ink pigments and the vinyl itself. Every outdoor sticker fades eventually. The question is how fast.

What makes stickers fade faster

  • Horizontal surfaces. A sticker on a hood, roof or boat deck faces the sun all day. The same sticker on a door or a wall gets far less. Flat and facing up is the toughest spot there is.
  • South-facing windows and walls in the northern hemisphere get the most direct sun.
  • Heat. Dark surfaces get hot, and heat speeds everything up.
  • Some colours. Bright reds, yellows and fluorescent colours tend to fade before blacks and blues.
  • No laminate. An unprotected print fades much faster.

Laminate: sunscreen for stickers

Every Mr. Stickers sticker gets a clear laminate over the print. It blocks a big share of UV, protects the ink from scratches, rain and car washes, and keeps colours rich for longer. It’s the single biggest thing that separates a sticker that lasts years from one that looks tired by fall.

So how long will mine last?

It depends on where it lives:

  • Indoors (laptops, notebooks, walls): many years.
  • Outdoors on vertical or partly shaded surfaces (water bottles, toolboxes, car doors): a few years before you notice much fading.
  • Outdoors, flat, in full sun all day: the toughest case. Expect noticeable fading sooner, roughly in the range our vinyl is rated for, which is about two years of harsh exposure.

Those are rough guides, not promises. A summer in the desert and a summer in Edmonton are very different things.

Helping them last

  • Apply to a clean surface so edges don’t lift and let dirt in.
  • Wash with mild soap and water; avoid pressure washers aimed at the edges.
  • Skip harsh solvents and abrasive polishes over the sticker.
  • For anything that has to look great for years in full sun, talk to us about upgraded materials.
