The Ultimate Guide to Re-sanding & Seal Coating Your Paver Patio After Power Washing
Written By: Spencer Bolinski, Owner of Wash Solutions LLC

Make sure to read our expert guide on how to properly wash a your deck
Your paver patio is more than just an outdoor living space—it’s an investment in your home’s beauty and value.
Over time, exposure to weather, foot traffic, and natural elements like moss and weeds can wear down its appearance and integrity.
But with proper maintenance, including resanding and seal coating after power washing, you can protect that investment for years to come. In this in-depth guide, we’ll walk you through the why, when, and how of resanding and seal coating your paver patio to keep it looking stunning and structurally sound.
Why Resanding and Seal Coating Are Critical for Patio Longevity
After a thorough power washing, your pavers are free of grime, mold, and weeds—but they’re also vulnerable. Cleaning strips away not only the dirt but also the polymeric sand and protective sealant that keep your patio looking sharp and functioning properly.
Here’s what resanding and sealing accomplish:
1. Joint Stabilization
Polymeric sand (not regular sand) locks the pavers in place. It hardens when activated with water, creating a durable, interlocking bond. Stabilized joints prevent shifting, sinking, and heaving—especially important in freeze-thaw climates.
2. Weed and Ant Prevention
Tightly packed, hardened joints leave no room for weed seeds or ant colonies. Sealing the surface adds another layer of defense by reducing gaps and water infiltration.
3. Color Enhancement and UV Protection
Sealers bring out the natural tones of your pavers, often making them richer and more vibrant. UV inhibitors in the sealer prevent fading, keeping your patio looking new.
4. Stain Resistance
A quality sealant creates a barrier against oil, grease, wine, and other spills—essential for outdoor kitchens or grill areas.
When Should You Resand and Seal Your Pavers?
Timing is everything. Here's what to consider:
After power washing: Always plan to resand and seal after deep cleaning to replenish what was removed.
Every 3–5 years: On average, sealing should be redone every 3–5 years depending on exposure and usage.
Spring or early fall: Ideal weather conditions are 50–85°F, with low humidity and no rain in the forecast for 24–48 hours.
Step-by-Step Guide: How to Resand and Seal Your Paver Patio
Let’s get into the nuts and bolts. Here’s how to do it right, from start to finish:
Step 1: Power Wash the Pavers Thoroughly
Tools & Materials:
- Power washer (preferably 2,500–3,000 PSI)
- Rotary surface cleaner attachment (optional, but great for even cleaning)
- Eco-friendly detergent (optional)
Process:
Remove furniture and decor. Sweep away loose debris. Pre-treat any mold or stains with a mild detergent. Use the power washer to clean in overlapping rows. Allow at least 24–48 hours for the pavers to dry completely before moving on to sanding.
Step 2: Inspect and Replace Damaged Pavers (Optional but Recommended)
Look for cracked, sunken, or shifted pavers. Carefully lift damaged units and reset or replace as needed. Ensure the base underneath is level and compacted.
Step 3: Apply Polymeric Sand
What You Need:
- Polymeric jointing sand (available in various colors)
- Push broom
- Leaf blower
Application:
Pour the polymeric sand directly onto dry pavers. Use a push broom to sweep the sand into the joints. Work diagonally to ensure even distribution. Once joints are filled, sweep away excess sand from the surface. Use a leaf blower on a low setting to remove fine dust without disturbing the filled joints.
Tip: Don’t rush this step. Poor sanding leads to weak joints and future weed problems.
Step 4: Activate the Polymeric Sand
How to Activate:
Set your hose nozzle to a gentle shower setting. Lightly mist the entire patio in multiple passes. Allow water to soak in and trigger the sand’s binding agents. Avoid over-watering, which can wash out the sand.
Important: Let the area dry for at least 24 hours. Avoid foot traffic and rain during this period.
Step 5: Seal the Pavers
Choose the Right Sealer:
Wet-look sealers: Enhance color and shine.
Natural-look sealers: Provide protection without altering appearance.
Solvent-based vs. water-based: Solvent-based are more durable, but water-based are easier and more environmentally friendly.
What You’ll Need:
- Paver sealer
- Pump sprayer or roller
- Paint tray (if rolling)Nitrile gloves and mask (especially for solvent-based sealers)
Application:
Read manufacturer instructions carefully. Apply in thin, even coats—start with one, allow to dry, then assess if a second is needed. Work in manageable sections. Avoid pooling or puddling.
Dry Time:
Surface dry: 2–4 hours
Foot traffic: 24 hours
Vehicle traffic: 48–72 hours
Because it holds installations together more homogeneously than conventional jointing materials, polymeric sand is a very hostile environment for weeds and pest infestations.

Common Mistakes to Avoid
Sealing too soon: Moisture in the pavers or joints can trap water and cause hazing.
Overfilling joints: Too much sand can sit on the surface and become difficult to clean.
Using regular sand: Polymeric sand is the only option for durable, weed-resistant joints.
Applying sealer on hot days: Rapid evaporation can lead to blotchy coverage.
Skipping the cleaning step: Dirt left behind will be sealed in permanently.
Long-Term Maintenance Tips
Spot clean spills immediately to prevent staining. Reapply sealer every 3–5 years or as needed.
Touch up joints with polymeric sand annually if erosion occurs. Use a leaf blower to keep debris off the surface. Avoid harsh chemicals that can break down sealers or destabilize the sand.

FAQs About Resanding and Sealing Pavers
Q: Can I skip the sealing step?
A: Technically yes, but it’s not recommended. Without a sealer, your patio is vulnerable to stains, fading, and water damage.
Q: How do I know when my patio needs to be resealed?
A: Pour a small amount of water on the surface—if it soaks in instead of beading, it’s time to reseal.
Q: Can I walk on the patio after sealing?
A: Wait at least 24 hours before walking and 48–72 hours before placing furniture or driving on it.
Conclusion: Invest in Longevity with Proper Care
Resanding and seal coating your paver patio after power washing is more than just a cosmetic upgrade—it’s an essential maintenance task that protects your investment and preserves its appearance. By following the steps above, you’ll enjoy a beautiful, weed-free, and durable patio for years to come.
