Clear Sealers: The What, The Why, The How and the Ahhhh effect

When it comes to protecting outdoor surfaces like pavers, concrete, stone, etc. a clear sealer can make all the difference. It’s one of the simplest ways to keep surfaces looking cleaner, stronger, and more vibrant while protecting them from moisture, dirt, and everyday wear. Whether you're sealing a patio, driveway, walkway, or pool deck, the right clear sealer helps extend the life of your surfaces without covering up their natural beauty.

Let’s break it down: The what, The why, The how and the satisfying Ahhhh moment when your project is complete.

What Is a Clear Sealer?

A clear sealer is a protective coating applied to surfaces like concrete, pavers, stone, and masonry to help protect them from moisture, stains, dirt, and weather damage. Unlike paints or coatings that hide the surface, clear sealers are designed to protect while allowing the natural texture and color of the material to remain visible.

There are two common types of clear sealers:

Penetrating (Lanco Natural-Look)

Penetrating sealers absorb into the pores of the surface to strengthen and protect it from within. These sealers maintain the natural appearance of the material and do not create a surface film, which means there is no peeling or flaking over time. They are ideal for homeowners who want protection while keeping the original look of their pavers, stone, or concrete.

Film-Forming Sealers (Lanco Wet-Look)

Film-forming sealers create a protective acrylic layer on top of the surface. These sealers enhance the color of the material and create a rich wet-look finish, giving patios, driveways, and walkways a deeper, more vibrant appearance. They also provide an additional barrier against moisture, dirt, and surface wear.

Why Seal My Surfaces?

Outdoor surfaces are constantly exposed to environmental elements that can slowly damage them over time. Applying a clear sealer helps protect against several common issues.

Moisture Damage

Concrete and stone are naturally porous materials. Water can penetrate these surfaces, leading to staining, cracking, and deterioration over time.

Sealers help reduce moisture intrusion and protect the integrity of the surface.

Dirt and Stains

Unsealed surfaces easily absorb dirt, oils, and debris. Sealing helps prevent these substances from penetrating the material, making surfaces easier to clean and maintain.

Mold and Mildew Growth

Outdoor surfaces, especially in humid climates, can develop mold and mildew. A quality sealer helps reduce the conditions that allow them to grow.

Surface Wear and Dusting

Concrete surfaces can gradually break down and produce dust over time. Sealers help strengthen the surface and reduce dusting and everyday wear.

Enhanced Appearance

Clear sealers can either preserve the natural look of the surface or enhance its color with a glossy wet finish, depending on the product used.

How to Seal My Surfaces

Sealing outdoor surfaces is a simple project that can dramatically improve their appearance and durability.

Step 1: Clean the Surface

Before sealing, remove dirt, stains, mold, and buildup from the surface. A proper cleaning ensures the sealer can bond effectively. For the best results use Lanco’s Roof Restore Cleaner, it succesfully removes dirt, mildew, chalk, and contaminants for proper adhesion and a clean finish.

Step 2: Let the Surface Dry

Moisture trapped in the surface can affect how the sealer performs. Allow the surface to dry completely before applying the sealer.

Step 3: Apply the Clear Sealer

Use a roller, sprayer, or brush to apply the sealer evenly across the surface. Follow the recommended coverage and drying times for best results: Natural-Look or Wet-Look

Step 4: Let It Cure

Once applied, allow the sealer to dry and cure properly before using the surface.

Natural-Look vs Wet-Look: Which Sealer Should I Choose?

Choosing between a natural-look sealer and a wet-look sealer depends on the visual result you want.

Lanco Natural-Look Sealer

• Maintains the original appearance of the surface

• Penetrates and protects porous materials

• No film formation, peeling, or flaking

Lanco Wet Look Sealer

• Enhances and deepens surface color

• Provides a high-gloss finish

Both options provide great protection; the difference is the finish you prefer.

The Ahhhh Moment

There’s a moment after sealing a patio, driveway, or walkway when everything just feels complete. The surface looks refreshed. The color is richer. The space feels cleaner and protected.

That’s the “ahhhh” moment when your outdoor space looks renewed and ready to enjoy and with the right sealer, that moment lasts far beyond the project day, helping keep your surfaces protected and beautiful for seasons to come.
