Florida’s beautiful weather is one of its biggest attractions, but when the rainy season rolls in, that same climate can become a serious challenge for your home’s exterior. Tropical downpours, flash flooding, and consistent high humidity are common throughout the state, and they can wreak havoc on outdoor surfaces—especially brick pavers.
Without the right protection, heavy rain and stormwater can damage your pavers by washing out sand, encouraging mold growth, and causing the surface to shift or deteriorate. But with the help of professional brick paver sealing, you can prevent these problems and maintain a safe, attractive, and long-lasting surface year-round.
At Premier Coatings, we specialize in helping Florida homeowners protect their pavers from the state’s most challenging weather conditions. In this article, we explain how sealing your pavers defends against rain and flooding—and why it’s a must for every Florida property owner.
Florida Rainfall and Its Impact on Pavers
Florida receives more than 50 inches of rain annually in many regions. During summer and hurricane season, it’s not uncommon for storms to drop several inches of rain in a single afternoon. That much water in a short period can expose weaknesses in any outdoor surface.
Brick pavers are designed to be durable, but they are not immune to water-related issues. Pavers are porous and absorb moisture easily. When left unsealed, water can penetrate the surface and cause erosion, mold, and discoloration. Rainwater can also wash away the joint sand between pavers, leading to loose bricks, uneven areas, and weed growth.
Flooded areas and poor drainage only make the problem worse. When standing water settles into unsealed pavers, it accelerates degradation, especially in shaded or low-lying zones.
The Role of Sealing in Moisture Protection
Sealing your brick pavers creates a protective barrier that repels moisture while still allowing the surface to breathe. This helps keep rain and floodwater from soaking into the bricks and damaging their structure.
At Premier Coatings, our paver sealing process begins with a thorough cleaning to remove mold, algae, and grime. We then refill joint sand to stabilize the surface before applying a high-performance sealer that protects against moisture, stains, and UV exposure.
Once sealed, your pavers are far better equipped to handle Florida’s frequent storms and seasonal flooding. Water beads on the surface instead of soaking in, helping your pavers dry faster and stay in better condition longer.
Why Joint Sand Matters in Rain Protection
One of the most overlooked aspects of storm protection for pavers is the condition of the joint sand. The sand between your pavers is what keeps them aligned and prevents movement.
When heavy rain or floodwater washes this sand away, your pavers become unstable. Loose pavers can shift, sink, or become tripping hazards. Eroded joints also leave room for weeds and moss to grow, making the surface harder to maintain and more prone to damage.
Our paver maintenance service includes sanding and sealing to lock that joint material in place. This step not only improves stability but also protects the joints from erosion during heavy rainfall.
Mold and Algae: A Rainy Season Hazard
Where there’s moisture, mold and algae are sure to follow—especially in Florida’s humid environment. These growths not only discolor your pavers but also make them slippery and unsafe to walk on, especially when wet.
Sealing helps prevent this by reducing the amount of moisture that penetrates the surface. Because water can’t settle into sealed bricks as easily, mold and algae have a harder time taking hold. Surfaces stay cleaner longer, and regular washing becomes much easier.
We always start by deep cleaning the surface before sealing. If your pavers already have mold, mildew, or algae, our brick paver cleaning process uses commercial-grade pressure washing and algaecide treatments to completely remove growth and prepare the surface for protection.
Better Drainage and Surface Integrity
Another benefit of sealing is that it helps your paver surface drain more efficiently. While sealing doesn’t stop water from entering your yard, it prevents that water from saturating and breaking down your hardscape.
When combined with proper grading and base compaction, sealed pavers are far more resistant to displacement caused by water. They stay level, drain properly, and retain their structural integrity during even the heaviest rainstorms.
This is especially important for pool decks, driveways, and walkways—areas that get a lot of use and are more likely to be affected by standing water.
When to Seal in Florida’s Climate
We recommend sealing your pavers every two to three years, depending on traffic, exposure, and rainfall. If you’re preparing for the rainy season or recently experienced flooding, it’s wise to schedule a professional inspection and service.
Even if your pavers are only a few years old, they may be vulnerable to moisture if they’ve never been sealed or if the old sealant has worn away.
