Outdoor materials take a beating from the elements, but with the right sealing, you can protect your investment and maintain a beautiful, functional outdoor space for years to come.

The Importance of Sealing

Sealing is the process of applying a protective treatment to the surface of wood, concrete, or masonry to prevent damage from moisture, UV rays, staining, and wear. Permanent sealing refers to high-performance products designed for long-lasting protection.

• Sealing works by penetrating deep into the material or bonding strongly at the surface level, creating a barrier against environmental and structural degradation.
• It’s not just about aesthetics; sealing also has functional benefits, such as preventing moisture absorption, improving surface strength, adding slip resistance, and reducing cleaning frequency.

The Benefits of Sealing for Different Materials

Wood Surfaces

Decks and docks, fences, pergolas, and cabins all benefit from sealing, as they’re exposed to harsh weather conditions and heavy foot traffic.

• Decks and docks are prone to warping, rotting, and splintering due to moisture and foot traffic.
• Fences and pergolas require protection from UV damage and water infiltration.
• Cabins need sealing to prevent rot and damage from moisture.

Masonry and Hardscapes

Concrete patios and walkways, pavers and stone paths, retaining walls, and vertical masonry all benefit from sealing to prevent cracking, staining, and erosion.

• Concrete patios and walkways are prone to cracking and staining due to oil and rust.
• Pavers and stone paths absorb moisture and attract grime.
• Retaining walls and vertical masonry are vulnerable to water penetration and algae growth.

The Risks of Not Sealing

Leaving your outdoor surfaces unsealed can lead to costly repairs and maintenance down the road.

• Wood: warping, rotting, splintering, and greying from sun damage.
• Concrete and pavers: surface cracking, fading, staining from oil or rust.
• Stone and masonry: crumbling edges, mildew buildup, erosion in joints.

How Long Does Sealing Last?

Sealing can last anywhere from a few months to several years, depending on the product, environment, and surface condition.

1. Penetrating sealers can last up to 10 years or more.
2. Surface sealers may need to be reapplied annually.

Is Sealing Just for Appearance or Does it Improve Function?

Both! Sealing enhances the appearance of outdoor surfaces while also providing functional benefits, such as preventing moisture absorption, improving surface strength, and adding slip resistance.

Example of Sealing Benefits

Sealing a deck can improve its structural stability and aesthetic appeal, while sealing a concrete patio can reduce cleaning frequency and prevent damage from moisture.

How to Prepare Your Surface for Sealing

It’s essential to clean and dry your surface before applying sealant to ensure a strong bond and optimal results.

• Pressure washing or brushing
• Removing grease or mildew
• Repairing cracks or damaged boards
• Allowing full drying time before sealing

Can Sealing Prevent Mold and Algae Growth?

Sealing can reduce moisture absorption, making it harder for mold and algae to take hold.

Example of Sealing’s Effectiveness

Sealing a stone surface can reduce the formation of mold and algae, making future cleaning easier.

The Difference Between Penetrating and Surface Sealers

Penetrating sealers soak into the material, providing protection from within, while surface or film-forming sealers sit on top, adding a glossy or wet look.

When to Reseal Your Surface

Signs that your surface needs resealing include water absorption, fading, mildew or stain formation, and surface brittleness.

DIY Sealing vs. Hiring a Professional

DIY sealing is possible, but larger areas or intricate surfaces often benefit from professional expertise.

Final Thoughts

Sealing your outdoor materials is a simple way to protect your investment and maintain a beautiful, functional outdoor space.
