How to Seal Pavers for a Long-Lasting, Vibrant Patio
Why Seal Patio Pavers?
Sealing pavers involves applying a protective coating that penetrates or coats the surface, shielding it from water, UV rays, and stains. In Florida, where patios endure intense sun and tropical storms, sealing offers:
Enhanced Durability: Prevents erosion, cracking, or fading, saving $1,000–$5,000 in replacement costs.
Vibrant Aesthetics: Enhances color and sheen, complementing your coastal patio’s wind chimes or tropical plants.
Weed Prevention: Blocks moisture and soil, reducing weed growth between pavers.
Stain Resistance: Repels oil, grease, or mildew, keeping your patio clean and safe.
Storm Readiness: Strengthens pavers against hurricane-driven rain and debris, protecting nearby pool enclosures (140–150 mph wind resistance).
Cost Savings: DIY sealing costs $50–$150 versus $300–$800 for professional services.

Step-by-Step Guide to Sealing Patio Pavers
Follow these steps to seal your patio pavers safely and effectively:
Step 1: Prepare Your Workspace Clear the patio, moving furniture, wind chimes, or potted plants to a safe area. Cover nearby pool enclosure screens (e.g., 20x20 No-See-Um or Florida Glass) with a tarp to protect against overspray. Sweep loose debris with a broom. Wear gloves and safety glasses to shield against water, debris, or sealer. Ensure the pressure washer is on a stable surface.
Step 2: Inspect the Patio and Enclosure Check pavers for cracks, loose stones, or worn joints. Inspect the pool enclosure’s base track and 5/16” head x 3” Tapcon screws for rust, tightening or replacing them with an electric hammer drill and 3/16” x 6” bit if needed. Note any paver damage for repair after cleaning to maintain hurricane readiness.
Step 3: Clean the Pavers Mix Simple Green Oxy Solve with water in a bucket (1:10 ratio) for general cleaning. For algae or mildew, fill a spray bottle with a 1:1 mix of white vinegar and water. Apply the vinegar solution to stains, let it sit for 5–10 minutes, then scrub with a soft-bristle brush. Pressure wash pavers with a 25-degree nozzle at 2700–3000 PSI, holding the nozzle 6–12 inches from the surface at a 45-degree angle. Work in 3–5 ft sections, rinsing off cleaner residue. Avoid high-pressure settings (over 3000 PSI), which can erode pavers or damage enclosure components.
Step 4: Fill Joints with Polymeric Sand Once pavers are dry (24–48 hours), sweep polymeric sand into joints using a broom, ensuring even filling. Gently mist the sand with a hose to activate its binding properties, following product instructions (e.g., Sakrete Polymeric Sand). Remove excess sand with a broom. This step prevents weed growth and stabilizes pavers, crucial for Florida’s wet climate.
Step 5: Apply Paver Sealer Choose a water-based penetrating sealer (for natural texture) or wet-look sealer (for enhanced color and gloss), like BEHR Premium Wet-Look Sealer. Pour sealer into a roller tray and use a paint roller with a long handle to apply an even coat, working in 3–5 ft sections. Start at one end and roll in one direction to avoid overlap marks. For edges or tight spaces, use a brush. Apply a second coat if recommended, waiting 2–4 hours between coats. Ensure good ventilation and avoid foot traffic for 24–48 hours.
Step 6: Rinse Nearby Surfaces Use a low-pressure hose (under 800 PSI) to rinse any overspray from the enclosure’s base track or screens, preventing sealer residue from attracting dirt. Clean the track with Simple Green to maintain its coastal aesthetic.
Step 7: Final Inspection Check pavers for uneven sealing, missed spots, or excess sand. Verify that enclosure screens and Tapcon screws are unaffected by overspray. Ensure the sealer has cured (24–48 hours) before replacing furniture or decor, confirming a vibrant, protected surface.
Tips for Success
Seal in Mild Weather: Apply sealer in 50–85°F, avoiding rain or direct sun to prevent bubbling or streaking.
Test Sealer: Apply a small amount to an inconspicuous area to check color and finish.
Protect Enclosure: Keep spray away from screens to avoid damage to splines or Florida Glass.
Work in Sections: Apply sealer methodically to ensure even coverage.
Maintaining Your Sealed Patio
Keep your patio vibrant and hurricane-ready with these tips:
Clean Regularly: Pressure wash every 6–12 months with Simple Green to remove dirt and algae, especially in coastal New Port Richey.
Inspect Joints: Check polymeric sand annually, reapplying if washed out ($20–$40 per bag).
Maintain Enclosure Components: Rinse 5/16” head x 3” Tapcon screws and hurricane cables every 6 months to remove salt. Replace rusted screws using a 3/16” x 6” bit.
Storm Prep: Before hurricane season (June 1–November 30), secure furniture, wind chimes, or decor indoors to protect the patio and enclosure. Trim trees to prevent debris damage.
Reapply Sealer: Reapply sealer every 1–2 years to maintain protection, following the same process.
Product Recommendations
Cleaner: Simple Green Oxy Solve Deck and Fence Cleaner ($10–$15, Home Depot).
Sand: Sakrete Polymeric Sand ($20–$40, Lowe’s).
Sealer: BEHR Premium Wet-Look Sealer ($20–$50, Home Depot).

Common Mistakes to Avoid
Using High Pressure: Exceeds 3000 PSI, risking paver erosion or enclosure damage.
Skipping Cleaning: Dirt or algae under sealer causes uneven finishes.
Overapplying Sealer: Excess sealer pools, creating sticky or cloudy spots.
Ignoring Safety: Wear gloves and glasses to avoid injury from water or sealer.
