Polymeric sand is the stuff that fills gaps between pavers and hardens like weak concrete in Orlando. It stops weeds, prevents ants, and keeps pavers from shifting.
But here's the problem: Florida's humidity makes polymeric sand tricky to install. Get it wrong and you'll have a white hazy mess all over your pavers that's nearly impossible to remove.
The 3 keys to success in Orlando:
Install during dry weather (NOT during rainy season if possible)
Choose humidity-resistant formula (Alliance Gator Maxx G2 or Techniseal RG+)
Follow activation steps EXACTLY (too much water = haze, too little = won't harden)
In this guide:
What polymeric sand actually is and why you need it
Step-by-step installation process for Florida climate
Which brands work best in Orlando humidity
How to avoid the dreaded polymeric sand haze
Troubleshooting when it doesn't dry properly
When to re-apply (every 3-5 years)
DIY vs hiring a pro
Bottom line: Polymeric sand is worth using, but you MUST install it correctly or you'll wish you just used regular sand.
What Is Polymeric Sand and Why Do Orlando Pavers Need It?
What It Is:
Polymeric sand = Regular sand + polymer additives
When you wet it, polymers activate and bind the sand together. It hardens in 24-48 hours into a semi-flexible solid that:
Stays in joints (doesn't wash away like regular sand)
Prevents weeds from growing up through joints
Stops ants from tunneling between pavers
Locks pavers in place (prevents shifting)
Resists erosion from rain and pressure washing
It's NOT concrete. You can still remove individual pavers if needed (with effort).
Why Orlando Pavers Need It:
Without polymeric sand, you'll have:
❌ Weeds everywhere - Seeds blow into joints and germinate
❌ Fire ants - Florida's #1 pest loves nesting between pavers
❌ Washout - 50+ inches annual rain washes regular sand away
❌ Paver shifting - Nothing holds pavers firmly in place
❌ Constant maintenance - Re-sanding every 6-12 months
With polymeric sand:
✅ Weed-free joints for 3-5 years
✅ Ant-resistant (can't tunnel through hardened sand)
✅ Erosion-resistant (stays put during thunderstorms)
✅ Stable pavers (locked in place)
✅ Re-sand only every 3-5 years instead of yearly
The Cost Difference:
Regular sand: $50 for 400 sq ft
BUT: Washes away, needs replacement every year
5-year cost: $250
Polymeric sand: $200-$300 for 400 sq ft
Lasts 3-5 years
5-year cost: $200-$300
Polymeric sand actually costs LESS over time while working better.

90% of Orlando paver contractors use Alliance Gator Maxx G2 or Techniseal RG+ because they're reliable in our humid climate.
How to Install Polymeric Sand on Pavers (Florida-Specific Instructions)
Timing is EVERYTHING in Orlando. Choose your installation day carefully.
Before You Start - Pick the Right Day:
Perfect conditions:
No rain for 2-3 days BEFORE installation
No rain forecast for 24-48 hours AFTER installation
Temperature 50-90°F
Humidity below 70% (rare in Orlando, but winter mornings work)
NOT during summer rainy season (June-September)
Best months in Orlando: November through March
Tools & Materials You Need:
Materials:
Polymeric sand (calculate 1 bag per 50-75 sq ft)
Leaf blower or broom
Tools:
Stiff bristle broom
Leaf blower (most important tool)
Garden hose with fine mist nozzle
Knee pads (you'll be on your knees)
Rubber gloves
Time needed: 4-6 hours for typical 400 sq ft area
Step 1: Clean Joints Completely (30-60 minutes)
This is the most important step.
Remove ALL old sand from joints
Use pressure washer (3000+ PSI) OR
Use stiff wire brush to scrape out joints OR
Use shop vac to vacuum out loose sand
Joints must be at least 1/2 inch deep
Measure with ruler or screwdriver
Polymeric sand needs depth to work properly
Too shallow = won't harden properly
Sweep entire paver surface clean
No debris, leaves, dirt on top
Bone dry pavers (CRITICAL)
Pro tip: Do this step the day before. Let everything dry overnight.
Step 2: Apply Polymeric Sand (45-60 minutes)
Pour sand onto pavers in several piles
Don't dump one huge pile
Spread piles around for easier sweeping
Sweep sand into joints
Use push broom at 45-degree angle
Sweep in multiple directions (N-S, then E-W)
Fill joints completely to top of chamfer (beveled edge)
Keep sweeping until joints are packed full
Overfill slightly
Sand will compact when wet
Better to overfill than underfill
Step 3: Remove Excess Sand from Surface (20-30 minutes)
THIS STEP PREVENTS HAZING (the white mess)
Use leaf blower on HIGH setting
Blow across pavers (not down into joints)
Remove every grain of sand from paver surface
Pay extra attention to textured pavers (sand hides in texture)
Check in sunlight
Any sand left on surface = future haze
Seriously, get EVERY bit off
Don't skip this step
Haze removal is 10x harder than prevention
Pro tip: Blow off excess, then blow off again. Then one more time.
Step 4: Compact Sand (15 minutes)
Run plate compactor over pavers
Use rubber pad attachment (don't scratch pavers)
2-3 passes over entire area
Compacts sand down into joints
Add more sand if needed
Joints should still be full after compacting
Top up any low joints
Blow off surface again
Compacting may bring sand to surface
Remove it before wetting
If you don't own compactor: You can skip this for small areas, but large driveways should be compacted
Step 5: Activate with Water (30-45 minutes)
This is where Orlando humidity causes problems. Follow exactly:
Set hose to FINE MIST
NOT hard stream (will wash sand out)
Not too light (won't activate polymers)
Fine shower/mist setting
Wet entire area slowly
Start at one end, work systematically
30-60 seconds per 10 sq ft section
You want water penetrating joints, not pooling on top
Look for proper wetting:
Joints should look dark/wet
Surface should have thin water film
No puddles, no dry spots
Wait 10 minutes, then mist again
Second light misting ensures full activation
Alliance Gator Maxx G2 only needs one misting
Techniseal RG+ can handle rain in 15 minutes
Step 6: Stay Off and Wait (24-48 hours)
Curing time:
Light foot traffic: 24 hours
Full vehicle traffic: 48-72 hours
NO rain for 24 hours minimum (check forecast!)
What's happening:
Polymers are binding sand together
Creates flexible-but-solid joint filler
If rain hits too soon, it'll wash out
If unexpected rain comes: You're probably OK if sand had 2+ hours to start setting. Heavy rain in first 30 minutes = redo the job.
Step 7: Final Check (After 48 hours)
Look for:
✅ Joints fully filled and hardened
✅ No haze on paver surface
✅ Sand firm to touch (can't easily scrape out with fingernail)
✅ No loose sand on surface
If you have haze: See troubleshooting section below
How to Deal with Orlando Humidity When Installing Polymeric Sand
Florida's 70-90% humidity causes these problems:
Problem #1: Sand Won't Dry/Harden
Symptoms:
48+ hours later, sand still soft
Can scrape out with fingernail
Joints feel damp
Causes:
Too much water applied during activation
Installed during high humidity (summer afternoon)
Cheap polymeric sand not designed for humid climates
Solutions:
Wait longer (up to 7 days in summer)
Use fan or leaf blower to increase air circulation
Hope for sunny, dry days
If still soft after 7 days, remove and redo with better brand
Problem #2: White Haze on Pavers
Symptoms:
Cloudy white film on paver surface
Can't easily wash off
Looks terrible
Causes:
Didn't remove all sand from surface before wetting
Polymers dried on paver surface instead of in joints
Applied during high humidity (polymers don't dry, they smear)
Solutions:
For fresh haze (within 24 hours):
Scrub with stiff brush and water immediately
May come off with effort
For set haze (after 24 hours):
Try efflorescence remover (acidic cleaner)
Pressure wash on low setting
Worst case: Hire professional restoration service ($300-$800)
Prevention: Blow off excess sand completely before wetting. Cannot stress this enough.
Problem #3: Sand Washed Out by Rain
Symptoms:
Rain came during curing period
Joints partially empty
Sand on surface
Solutions:
Let dry completely (2-3 days)
Add more polymeric sand to refill joints
Re-activate with light misting
Consider it a lesson about checking weather forecast
When Do You Need to Re-Apply Polymeric Sand?
Expected Lifespan in Orlando:
Good quality polymeric sand (Alliance, Techniseal):
3-5 years typical lifespan
Some areas last 7+ years
High-traffic areas (driveway aprons) may need re-sanding at 2-3 years
Budget polymeric sand:
2-3 years if you're lucky
Often fails in 12-18 months in Florida
Signs You Need to Re-Sand:
🚨 Joints have empty gaps
🚨 Can easily scrape out sand with screwdriver
🚨 Weeds growing in joints
🚨 Ants making homes between pavers
🚨 Pavers shifting or rocking when walked on
🚨 Visible erosion after rain
Don't wait until all joints are empty. Re-sand when 20-30% of joints show wear.
Re-Sanding Cost:
DIY: $200-$400 in materials for 400 sq ftProfessional: $400-$800 installed
Schedule: Budget for re-sanding every 3-4 years as part of paver maintenance.
Should You Install Polymeric Sand Yourself or Hire a Professional?
DIY Makes Sense When:
✅ Small area (under 200 sq ft)
✅ You're handy and patient
✅ You can wait for perfect weather (dry forecast)
✅ You have pressure washer and leaf blower
✅ Budget is tight
DIY cost: $200-$400 for 400 sq ft DIY time: 6-10 hours including prep
Hire a Pro When:
✅ Large area (over 300 sq ft)
✅ Expensive pavers (don't risk haze on $15,000 pool deck)
✅ Don't have right tools
✅ Can't control timing (pros work around weather)
✅ Want warranty on work
Professional cost: $1.50-$3.00 per sq ft installed
400 sq ft: $600-$1,200
Includes prep, materials, labor, cleanup, warranty
What Pros Bring:
Experience avoiding haze (biggest homeowner mistake)
Commercial-grade materials at wholesale cost
Right tools (industrial blowers, professional compactors)
Weather flexibility (can work faster between rain)
Warranty (1-2 years typically)
Honest Opinion:
Small patio (100-200 sq ft) = Try DIY Driveway or large area = Hire pro Pool deck = Definitely hire pro (too visible, too expensive to mess up)
How to Make Polymeric Sand Last Longer in Orlando
5 tips to extend lifespan:
Tip #1: Don't Pressure Wash Joints
Pressure wash AROUND joints, not directly on them
High PSI blasts out polymeric sand
Use 15-25 degree tip, not narrow 0-degree
Keep wand at angle, not straight down
Tip #2: Seal Your Pavers
Sealer protects polymeric sand from UV breakdown
Sealing every 3-4 years makes sand last longer
Joint stabilizing sealers add extra protection
Cost: $1-2 per sq ft every 3-4 years
Tip #3: Fix Damage Quickly
If you see missing sand in spots, refill immediately
Don't wait for all joints to fail
Spot-filling costs $50-$100
Letting it go = full re-sand for $400-$800
Tip #4: Control Vegetation
Trim back plants that overhang pavers
Remove leaves and debris regularly (traps moisture)
Organic matter breaks down polymeric sand faster
Tip #5: Address Drainage Issues
Fix sprinklers spraying directly on pavers
Redirect downspouts
Constant water = faster sand degradation
