DIY Pressure Washing: How to Clean Your Patio Without Damaging It
Why Pressure Wash Your Patio?
Pressure washing uses high-pressure water (typically 2700–3000 PSI) to remove dirt, algae, mildew, and stains from patio surfaces like concrete, pavers, or stone. Regular cleaning enhances your patio’s functionality and coastal aesthetic, offering:
Improved Appearance: Restores vibrant colors, complementing wind chimes or potted plants for a coastal vibe.
Safety: Removes slippery algae or mildew, preventing falls near your pool enclosure.
Longevity: Prevents surface erosion or staining, saving $500–$5,000 in repairs or resurfacing.
Storm Readiness: Clean surfaces reduce debris that could stress enclosure components during hurricanes (140–150 mph winds).
Cost Savings: DIY pressure washing costs $50–$150 versus $200–$500 for professional services.

Step-by-Step Guide to Pressure Washing Your Patio
Follow these steps to clean your patio 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., Florida Glass or 20x20 No-See-Um) with a tarp to protect against overspray. Sweep loose debris with a broom. Wear gloves and safety glasses to shield against water and debris. Ensure the pressure washer is on a stable, flat surface.
Step 2: Inspect the Patio and Enclosure Check the patio surface for cracks, loose pavers, or worn sealant. 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 damage for repair after cleaning to maintain hurricane readiness.
Step 3: Pre-Treat Stains 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 stained areas, let it sit for 5–10 minutes, then scrub gently with a soft-bristle brush. For large areas, apply the Simple Green solution with the brush, working in 3–5 ft sections.
Step 4: Set Up the Pressure Washer Attach the 25-degree green nozzle to the pressure washer for a wide, gentle spray. Test the pressure on an inconspicuous area, keeping the nozzle 6–12 inches from the surface and maintaining 2700–3000 PSI. Avoid higher PSI or narrow nozzles (e.g., 0-degree red tip), which can etch concrete or damage pavers.
Step 5: Pressure Wash the Patio Start at one end of the patio, holding the nozzle at a 45-degree angle, 6–12 inches from the surface. Move in slow, overlapping passes, working in 3–5 ft sections. Keep the spray moving to avoid etching or streaking. For large patios, use a surface cleaner attachment for even results. Rinse off cleaner residue as you go, ensuring no soap or vinegar remains.
Step 6: Rinse Thoroughly Switch to a low-pressure setting (under 800 PSI) or use a garden hose to rinse the entire patio, removing all cleaner and debris. Start at the highest point and work down to prevent streaking. Check for missed spots, repeating step 5 if needed. Ensure no overspray reaches the enclosure’s screens or aluminum frame.
Step 7: Apply Concrete Sealer (Optional) For added protection, apply a penetrating concrete sealer once the patio is dry (24–48 hours). Use a roller or sprayer to apply an even coat, following product instructions. Sealers like BEHR Premium Wet-Look Sealer ($20–$50) enhance color and protect against water and UV damage, ideal for Florida’s climate.
Step 8: Final Inspection Check the patio for streaks, stains, or damage. Verify that enclosure screens and Tapcon screws are unaffected by overspray. Clean the base track with Simple Green to remove any splashed dirt, preserving the enclosure’s coastal aesthetic.
Tips for Success
Wash in Mild Weather: Avoid hot days, as cleaners dry quickly and streak.
Test Pressure: Start with low pressure on a small area to ensure no damage.
Protect Enclosure: Keep spray away from screens to avoid stretching or spline displacement.
Work in Sections: Clean small areas to maintain control and avoid uneven results.
Maintaining Your Patio
Keep your patio vibrant and hurricane-ready with these tips:
Clean Regularly: Pressure wash every 6–12 months to prevent algae buildup, especially in coastal New Port Richey.
Inspect for Damage: Check annually for cracks or loose pavers, using a concrete patch kit ($10–$20) for minor repairs.
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: Apply concrete sealer every 1–2 years to maintain protection.

Common Mistakes to Avoid
Using High Pressure: Exceeds 3000 PSI, risking etching or paver damage.
Skipping Pre-Treatment: Leaves algae or stains, requiring repeat cleaning.
