Can You Pressure Wash Brick Pavers?
Yes, they can be, but carefully. Too much pressure or improper techniques can erode mortar, dislodge sand, or even crack the surface. Cleaning pavers properly is essential in Fort Pierce, where humidity and salt air cause rapid wear.
The Dos
- Use the Right Pressure (500–800 PSI max)
High-pressure settings (above 1,000 PSI) can damage pavers. Dirt can be removed without damaging the surface by using a fan-tip nozzle for a gentle wash. - Pre-Treat Stains
Before washing, apply a mild detergent or paver-safe cleaner. For stubborn mold or algae, you can use a diluted vinegar solution to break down the buildup. - Maintain Proper Distance (12–18 inches)
Holding the nozzle too close can break the surface. Move evenly across the surface while maintaining a safe distance. - Re-Sand Joints After Washing
It can wash away joint sand. Once dry, replenish polymeric sand to prevent shifting and weed growth. - Rinse Thoroughly
Leftover soap residue can attract dirt. After cleaning, always rinse with fresh water.
The Don’ts
- Avoid Steam or Hot Water
Heat can cause color fading and mortar weakness. If you want to clean safely, use cold water. - Skip the Turbo Nozzle
Concentrated spray patterns gouge surfaces. A wide-angle nozzle distributes pressure evenly. - Don’t Ignure Existing Damage
Are the pavers loose or cracked? Pressure washing can make problems worse. Repair damage before cleaning. - Never Rush the Job
Hastily blasting pavers leads to uneven cleaning or damage. Slow, steady strokes work best.
Don’t Forget to Seal (When Needed)
They should only be sealed after washing if they are completely dry and in good shape in order to prevent stains.

Frequently Asked Question(s)
What’s the best time to pressure wash pavers?
Cool, overcast days prevent rapid drying, which can leave streaks.
Can I use bleach on paved surfaces?
Diluted bleach is safe for killing algae, but it can harm nearby plants. Rinse thoroughly.
Can I use pressure washing on colored surfaces without fading the color?
Yes, but be cautious with the pressure setting and cleaning solution. Low PSI and a masonry-safe cleaner will help preserve the color of your stones.
How do I apply a sealant to my paving surfaces after cleaning?
After pressure-washing and ensuring the surface is dry, apply a paver-safe sealant to protect the paving stones or concrete. Always follow the manufacturer’s recommendations for optimal results.
Is it normal for bricks to darken when wet during cleaning?
Yes, this temporary color change occurs as pores absorb water. Colors should return to normal within 48 hours of drying.
