| UV Fading | More prone | Better protected |
| Color Vibrancy | Fades faster | Maintains longer |
How Do They Compare in Stain Resistance?
- Unsealed pavers: Easily stained, require frequent cleaning
- Sealed pavers: Less susceptible to staining, easier to maintain
What About Wear Resistance?
- Unsealed pavers:
- Require more frequent maintenance
- Higher risk of moss and weed growth
