Question
Which mounting substrate should I choose for outdoor use?
Answer
For anything facing the weather, skip foam core. It warps in humidity and sun. Step up to a rigid, moisture-resistant substrate.
| Substrate | Outdoor suitability |
|---|---|
| Foam core | Indoor only, warps outdoors |
| Gatorboard | Holds up in mild, sheltered outdoor conditions |
| Aluminum / metal panels | Best for full weather and UV resistance |
- Match the substrate to how long the sign stays outside and how exposed it is
- Aluminum panels handle both indoor and outdoor duty
- Seal or laminate the print for extra protection against moisture and fading
