Outdoor tile and stone look stunning—until the elements take their toll. Rain, sun, dirt, and mildew all work against you. Without protection, those beautiful surfaces don’t stay beautiful for long.
That’s why sealing is essential.
Outdoor Surfaces Are Under Constant Attack
Unlike indoor areas, outdoor tile and stone face year-round abuse. UV rays fade the color. Rainwater seeps into porous materials. Dirt and grime grind in. Mold and mildew find the perfect place to grow—especially in shaded, damp areas.
Even freeze-thaw cycles can cause cracking. Water seeps in, freezes, expands, and creates damage from the inside out.
Tile and Stone Are Porous by Nature
Most natural stones—like travertine, slate, limestone, and granite—are porous. Even outdoor porcelain tile can benefit from sealing, especially around grout lines. Left unsealed, these materials absorb moisture and stains.
Sealing forms a protective barrier. It blocks moisture. It helps prevent staining. It makes routine cleaning easier.
Sealing Enhances Appearance
It’s not just about protection—it’s about appearance too. A quality sealer enhances color depth. Some add a glossy or “wet look,” while others keep a matte, natural finish.
Sealed surfaces tend to look richer, more vibrant, and more well-maintained over time.
Grout Lines Are Especially Vulnerable
Grout is usually more porous than the tile or stone itself. Outdoors, it’s one of the first places to break down. Crumbling grout leads to water intrusion, loose tiles, and structural issues.
Sealing protects the grout, keeps it intact longer, and stops discoloration.
Makes Maintenance Easier
Sealed surfaces resist stains and repel dirt. That means less scrubbing, fewer harsh cleaners, and better long-term results. When spills or stains do happen—like oil from a grill or mud from foot traffic—they’re easier to remove.
How Often Should You Seal?
Every 1–3 years is typical, depending on climate and traffic. High-use areas like patios, pool decks, and entryways may need sealing more often. You can do a simple water drop test—if the water soaks in instead of beading up, it’s time to reseal.
Protect Your Investment
Outdoor tile and stone aren’t cheap. Why let weather and time wear them down? Sealing helps extend their life, maintain their beauty, and prevent costly repairs.
If you want your outdoor surfaces to last—and look great doing it—don’t skip the sealer.
