When it comes to outdoor living spaces, pavers are a popular choice for their durability, versatility, and aesthetic appeal. However, to ensure their longevity and maintain their appearance, pavers require regular maintenance and protection from the elements. One of the most critical steps in paver maintenance is sealing, which helps to protect the pavers from stains, damage, and degradation. But what do professionals use to seal pavers?
The Importance of Sealing Pavers
Sealing pavers is not just a cosmetic enhancement; it’s a necessary step to extend the lifespan of your paver installation. Without proper sealing, pavers can become vulnerable to various types of damage, including:
- Stains: Oil, grease, food, and other substances can leave unsightly marks on unsealed pavers.
- Erosion: Water and weathering can cause pavers to shift, settle, or crack over time.
- Efflorescence: White salts can rise to the surface, creating an unsightly appearance.
- Freeze-thaw damage: Water can seep into the pavers and cause them to crack or break during freeze-thaw cycles.
By applying a sealant, professionals can create a barrier that protects the pavers from these types of damage, ensuring a safe, stable, and visually appealing outdoor space.
Types of Paver Sealers
There are several types of paver sealers available, each with its own unique characteristics, advantages, and disadvantages. Professionals typically choose from the following options:
Silane-Based Sealers
Silane-based sealers are a popular choice among professionals due to their exceptional penetration and durability. These sealers react with the silica in the pavers to form a strong, chemical bond that repels water and stains. Silane-based sealers are ideal for high-traffic areas and offer long-term protection.
Siloxane-Based Sealers
Siloxane-based sealers are another popular option, offering excellent water repellency and stain resistance. These sealers create a hydrophobic (water-repelling) coating that prevents water and stains from penetrating the pavers. Siloxane-based sealers are suitable for most paver applications and provide a moderate level of protection.
Acrylate-Based Sealers
Acrylate-based sealers are a popular choice for decorative pavers and those with a high-gloss finish. These sealers provide a clear, non-yellowing coating that enhances the paver’s appearance while offering moderate protection against stains and water.
Wax-Based Sealers
Wax-based sealers are a budget-friendly option that provides a short-term fix for pavers. These sealers create a physical barrier that repels water and stains, but they can wear off quickly, requiring frequent reapplication. Wax-based sealers are best suited for low-traffic areas and decorative pavers.
Factors to Consider When Choosing a Paver Sealer
When selecting a paver sealer, professionals consider several factors to ensure the best results. Some of the key considerations include:
Paver Type
Different paver materials require specific sealers. For example, concrete pavers may require a silane-based sealer, while natural stone pavers may benefit from a siloxane-based sealer.
Color and Finish
The color and finish of the pavers can impact the choice of sealer. Some sealers may enhance or alter the appearance of the pavers, so it’s essential to choose a sealer that complements the paver’s natural color and finish.
Climate and Exposure
Pavers exposed to harsh weather conditions, such as heavy rainfall, intense sunlight, or extreme temperature fluctuations, may require a more durable sealer.
Traffic and Usage
High-traffic areas, such as commercial spaces or public walkways, may require a more heavy-duty sealer to withstand the wear and tear.
Applying Paver Sealer: Best Practices
Professionals follow specific guidelines to ensure a successful paver sealing project. Some of the best practices include:
Cleaning and Preparation
Thoroughly cleaning the pavers to remove dirt, debris, and old sealers is crucial. This ensures a strong bond between the sealer and the paver.
Sealer Selection and Application
Choosing the right sealer for the specific paver type, climate, and exposure is essential. Applying the sealer according to the manufacturer’s instructions, ensuring even coverage and avoiding over-application.
Drying and Curing
Allowing the sealer to dry and cure according to the manufacturer’s instructions is critical. This ensures the sealer forms a strong bond with the paver and provides optimal protection.

What is paver sealing, and why is it important?
Paver sealing is the process of applying a protective coating to pavers to prevent stains, protect them from the elements, and extend their lifespan. It’s an essential step in maintaining the beauty and integrity of paver installations. Sealing pavers helps to repel water, oil, and other substances that can cause discoloration and damage.
By sealing pavers, homeowners can enjoy a range of benefits, including enhanced appearance, improved durability, and reduced maintenance needs. Sealed pavers are also more resistant to weed growth, efflorescence, and damage from freeze-thaw cycles. Additionally, sealing pavers can help to prevent the growth of mold and mildew, which can create slippery surfaces and become a safety hazard.
What types of paver sealing solutions are available?
There are two primary types of paver sealing solutions: topical sealers and penetrative sealers. Topical sealers form a protective barrier on the surface of the pavers, while penetrative sealers soak into the paver material to provide long-lasting protection. Topical sealers are often used for aesthetic purposes, as they can enhance the color and appearance of the pavers.
Penetrative sealers, on the other hand, offer superior protection against stains, water damage, and other forms of deterioration. They are particularly useful for high-traffic areas, commercial properties, and exterior installations that are exposed to harsh weather conditions. A professional paver sealing expert can help determine the most suitable type of sealer for a specific project, taking into account factors such as paver material, traffic volume, and environmental conditions.
How often should pavers be sealed?
The frequency of paver sealing depends on various factors, including the type of pavers, traffic volume, and exposure to the elements.
