Introduction: The Debate on Sealing Pavers
Interlocking Pavers are one of the most popular choices for driveways, patios, walkways, and pool decks thanks to their durability and timeless appeal. But many homeowners ask the same question: Do I need to seal interlocking pavers?
Opinions are divided. Some people prefer the natural look of pavers without any sealant, while others swear by sealing to maintain color, resist stains, and extend lifespan.
Do I Need to Seal Interlocking Pavers? The Short Answer
Sealing is optional but recommended. Your pavers will perform well without it, but sealing offers added benefits in appearance and protection.
Sealing Is Optional but Recommended
Unsealed pavers can last for decades, but they may be more prone to fading, staining, and weed growth.
Benefits of Sealing Pavers
- Brings out vibrant color tones
- Protects against oil, grease, and food stains
- Helps prevent weed and moss growth
- Reduces erosion of joint sand
When Sealing May Not Be Necessary

Benefits of Sealing Interlocking Pavers
Enhances and Preserves Color
Sealants make colors look richer and more vibrant, preventing fading from sun exposure.
Protects Against Stains and Spills
Driveways and outdoor kitchens benefit from sealing since it helps resist oil, grease, and food stains.
Reduces Weed and Moss Growth
By locking in joint sand, sealers reduce the chances of weeds sprouting between pavers.
Improves Durability and Longevity
Sealed pavers are better protected from erosion, freeze-thaw damage, and weathering.
Drawbacks of Sealing Pavers
Initial and Long-Term Costs
Professional sealing can cost $1.50–$3.00 per square foot, and resealing is needed every few years.
Maintenance and Reapplication Needs
Sealers wear down over time, requiring resealing every 3–5 years.
Potential for Slippery Surfaces
Glossy sealers can make pavers slippery, especially around pool decks.
