Question
What materials should I use for outdoor posters that will be exposed to rain?
Answer
For posters that will face rain or weather, skip standard paper and choose a waterproof material that can shrug off moisture without warping.
| Material | Weather performance |
|---|---|
| Vinyl | Fully waterproof and flexible, ideal for outdoor use |
| Synthetic or plastic substrates | Water-resistant and tear-resistant |
| Coroplast | Rigid, water-resistant corrugated plastic for yard and lawn use |
| Standard paper | Indoor only, warps and tears when wet |
| Foam core | Indoor only, edges swell and delaminate in moisture |
- Add lamination for extra protection against rain and UV fading.
- Keep paper and foam core posters indoors, since they deteriorate quickly outside.
- For long outdoor runs, pair a waterproof substrate with a laminate for the best durability.
The best choice depends on your size and how long the poster stays outside, so confirm the material's weather rating before printing.
