One of the biggest mistakes homeowners make is assuming all sealers work the same way. In reality, the type of sealer used matters just as much as whether you seal at all—especially in Florida.
1. What Is a Film-Forming Sealer?
Film-forming sealers sit on top of the surface, creating a visible coating. These sealers are commonly used on brick pavers because they enhance color and provide a finished appearance.
When applied correctly, they offer strong protection—but when applied incorrectly, they can:
- Trap moisture
- Turn white or cloudy
- Peel or flake
- Become slippery
2. What Is a Penetrating Sealer?
Penetrating sealers soak into the pores of the surface instead of coating the top. They create a hydrophobic barrier beneath the surface that repels water while allowing vapor to escape.
This breathability is critical for Florida’s humid, moisture-rich environment.
3. Why Florida Conditions Matter
In many northern climates, moisture evaporates quickly. In Florida, moisture constantly moves up from the ground through the base material and into porous surfaces.
Sealants that trap moisture fail prematurely here—even if they work well elsewhere.
4. Choosing the Right Sealer for the Surface
- Brick pavers often benefit from professionally applied film-forming sealers
- Travertine, shellock, marble, and natural stone require penetrating impregnator sealers
Using the wrong product can cause permanent damage and expensive stripping.
5. Product Choice Is More Important Than Price
Cheap sealers often lack UV resistance, breathability, and durability. The result is failure within months instead of years. Professional-grade sealers cost more upfront but save significantly over time.oisture, and UV exposure. Commercial properties require higher-performance sealants applied by experienced professionals who understand Florida’s climate and compliance requirements.
