Does sealing brick steps provide benefits?

What are Brick Steps?

Brick steps are a classic construction that has been used for centuries to provide pedestrian access up and down elevation changes. Like other masonry surfaces, brick steps are composed of individual bricks laid together with mortar, making the surface porous and able to absorb water. Over time, unsealed brick steps can become damaged from exposure to weather elements.

Common Issues with Unsealed Brick Steps

Unsealed brick steps face several common issues:

• Water absorption: Causes bricks and mortar to break down more quickly from repeated freezing and thawing during winter. This can also lead to mold and mildew growth on the surface.
• Efflorescence: A white powdery substance that appears as water evaporates from the brick, indicating moisture has penetrated the steps.
• UV Damage: Sunlight can fade and degrade bricks over time.
• Weed Growth: Weeds often take root more easily on unsealed surfaces.

Overall, untreated brickwork requires significantly more maintenance and upkeep over time.

Role of Brick Sealing

Applying a brick sealer creates a barrier that helps prevent common issues by repelling water. The sealer minimally penetrates the porous surface of the brick to fill microscopic pores without altering its natural look. Once cured, the sealer forms a protective finish that helps maintain the structural integrity of the steps.

By reducing water absorption, sealing makes brick drier and less susceptible to freeze-thaw damage. It also inhibits mold, mildew, and weed growth, and offers UV protection to slow natural fading and deterioration of exposed brick steps.

Benefits of Sealing Brick Steps

Durability

Sealing enhances durability by creating a water-repellent barrier. This protects brick from water absorption, preventing freeze-thaw damage, efflorescence, and spalling. As a result, sealed brick can withstand weathering for 15-20 years or longer before requiring replacement or repair.

Enhanced Appearance

Sealing brings out the natural color variation in bricks, creating a cohesive and finished look. While unsealed surfaces absorb grime and dull in color, sealed brick retains a vibrant sheen. Minor stains wash away more easily, preserving an attractive presentation.

Protection Against Weather

Sealers shield brick from UV rays, temperature fluctuations, rain, and snow, which are major causes of deterioration. Sealed brick resists mold, mildew, and air pollution, which can accelerate natural wear and tear.

Prevention of Deterioration and Damage

Beyond extending lifespan, sealing prevents costly damage by protecting against cracking, scaling, and disintegration caused by water absorption and freezing. It also stunts moss, algae, and weed growth, helping brick maintain its shape and structure for much longer.

Maintenance of Brick Quality

With proper upkeep and sealing, high-quality brick can last over 50 years. Sealing supports the longevity of masonry by protecting details that define quality, allowing natural aging and wear to occur gracefully over time.

Sealed Vs. Unsealed Brick Steps

Lifespan

Unsealed brick steps may last 15-25 years before deterioration sets in. Brick sealed at installation or shortly after can last 15-20 years longer, depending on climate and sealer quality, effectively doubling the functional lifespan and delaying major repairs.

Maintenance Requirements

Unsealed brick requires extensive maintenance, such as power washing and repairing damage. Sealed brick needs only light cleaning a few times a year, reducing maintenance demands by 75% through its prime decades.

Aesthetic Appeal

Unsealed steps may show weathering and stains within 5-10 years. Brick sealed at installation maintains an elegant appearance with vibrant color for 15-20+ years, holding curb appeal and home value longer than unsealed surfaces.

FAQ Sealing Brick Steps

• What Is A Brick Sealer? A brick sealer is a protective coating applied to brick, concrete, or natural stone to prevent water and pollutants from penetrating. It fills pores on porous masonry materials, creating a barrier against elements. Sealers come in clear and colored formulas.
• How often should exterior brick be sealed? For brick exposed to typical weather, resealing every 3-5 years is recommended for optimal protection.
• What are the ideal weather conditions for sealing? Seal brick when temperatures are 50-80°F for at least 48 hours. Avoid applying in direct sunlight, rain, or snow, and wait 2-3 days after rain for curing.
• Does brick sealer prevent mold? While not fully mold-proof, many sealers include mildewicides, reducing mold growth by up to 60-80% compared to unsealed surfaces. Regular cleaning and good drainage also help prevent mold.
