Concrete pavers are a popular choice for homeowners looking to enhance the aesthetic and functionality of their driveways, patios, or walkways. While pavers offer durability and visual appeal, maintaining them properly is essential to ensure they last for years. One of the most important aspects of paver maintenance is sealing pavers. Additionally, many people wonder: can you put pavers over concrete? The answer isn’t as simple as yes or no — and both sealing and installation decisions come with important considerations.

In this guide, we’ll cover why sealing pavers is necessary, how the process works, and what you need to know if you’re thinking about installing pavers over an existing concrete surface.

Why Sealing Pavers Matters

Sealing pavers isn’t just about improving their appearance — it’s about protecting your investment. When left unsealed, pavers are vulnerable to moisture, staining, fading, and weed growth. A quality sealant creates a barrier that:

1. Repels water and moisture
   This prevents erosion and cracking caused by freeze-thaw cycles in colder climates.
   
   
2. Enhances color and texture
   Sealing brings out the natural tones of your pavers, giving them a richer, more polished look.
   
   
3. Resists stains and oil spills
   Ideal for driveways and outdoor kitchens where oil or grease spills are common.
   
   
4. Inhibits weed and moss growth
   Sealants help lock the joints between pavers, reducing gaps where weeds typically sprout.
   
   
5. Reduces fading from UV rays
   Especially important in sunny climates, where UV exposure can dull pavers over time.
   
   

How to Seal Pavers: Step-by-Step

If you’ve decided to move forward with sealing pavers, it’s crucial to follow the right process for best results. Here’s a basic overview:

1. Clean the Surface Thoroughly
   Remove dirt, debris, and stains. A pressure washer works best. Let the surface dry completely before applying sealer.
   
   
2. Check for Repairs
   Replace or reposition any loose, cracked, or sunken pavers before sealing.
   
   
3. Choose the Right Sealer
   There are two main types:
   
   
   • Film-forming sealers (give a shiny, wet look)
     
     
   • Penetrating sealers (more natural appearance)
     
     
4. Apply Evenly
   Use a sprayer or roller to apply the sealer in even coats. Avoid overapplication to prevent a hazy finish.
   
   
5. Allow to Dry and Cure
   Typically, sealed pavers need 24–48 hours to cure. Avoid walking or driving on them during this time.
   
   

Pro tip: Always read the manufacturer’s instructions and test a small area first before applying the sealer to the entire surface.

How Often Should You Reseal Pavers?

Generally, pavers should be resealed every 2–4 years, depending on factors such as:

• Exposure to sunlight and weather
  
  
• Type of sealer used
  
  
• Traffic (foot vs. vehicle)
  
  
• Drainage and installation quality
  
  

Neglecting this maintenance can lead to discoloration, moss buildup, and faster deterioration.

Can You Put Pavers Over Concrete?

Now let’s address a common question: Can you put pavers over concrete? The answer is yes, but there are important conditions to consider before doing so.

When It Works:

1. The concrete is structurally sound
   No major cracks, sinking, or crumbling. If your existing concrete surface is stable and level, you can use it as a base.
   
   
2. You use the correct installation method
   Pavers can be laid over concrete using a sand-set or mortar-set system. Sand-setting allows better drainage, while mortar-setting provides a permanent bond.
   
   
3. Height adjustments are manageable
   Adding pavers increases the surface height. You’ll need to make sure it doesn’t interfere with doors, drainage, or transitions.
   
   

Pros of Installing Pavers Over Concrete

• Saves time and labor: No need to demolish the existing concrete
  
  
• Cost-effective: Less excavation and disposal required
  
  
• Increased durability: Acts as a double-layer base
  
  

Cons to Consider

• Drainage issues: Concrete doesn’t allow water to pass through, which can lead to pooling if not properly sloped
  
  
• Height problems: Doors, steps, or garages might need adjustments
  
  
• Movement and shifting: Without edge restraints, the new paver layer can shift over time
  
  

If done incorrectly, installing pavers over concrete can lead to uneven surfaces and reduced longevity. Consulting a professional is highly recommended for this type of project.

Should You Seal Pavers Installed Over Concrete?

Yes — in fact, sealing pavers becomes even more important in this setup. Since water can’t seep through the concrete base, proper sealing helps direct moisture away and prevents buildup on the surface. It also improves bonding if mortar was used and protects the joints from erosion or weeds.

Making the Most of Your Paver Investment

Pavers are an excellent choice for adding elegance and value to any outdoor space. But whether you’re installing them over concrete or already have them in place, maintenance is key. Sealing pavers not only boosts curb appeal but also extends the life of your surface.

And if you’re asking yourself “can you put pavers over concrete?” — the answer is yes, as long as it’s done properly and with the right expectations. Make sure your base is solid, your installation method is sound, and your maintenance routine includes regular cleaning and sealing.

With the right care, your pavers can remain beautiful, functional, and structurally sound for decades.
