Should Paving Stones Be Sealed?

Paving stones, also called pavers, are a popular exterior flooring and hardscaping material. They are made from diverse materials, including natural stone (granite, slate, travertine, limestone, and basalt), concrete, and brick. Available in an endless assortment of sizes, textures, patterns, colors, and styles, paving stones are commonly used for driveways, walkways, porches, patios, pool decks, and outdoor kitchens. They make the outdoor space more functional and attractive. 

While installing paving stones, homeowners need to make the critical decision whether or not to seal them.  Though considered an optional process, most contractors and manufacturers recommend sealing the paving stones as a preventative maintenance step to preserve their beauty and keep them clean. As they are laid outside, paving stones are exposed to varied outdoor elements, making them susceptible to damage, spills, stains, and fading. Sealing helps in withstanding the elements and protecting the investment.

Let’s look at the various pros and cons of sealing paving stones to help homeowners decide whether to go ahead with the process or not.

Pros of sealing paving stones

• It gives paving stones a higher visual appeal. Some sealers enhance the natural color and beauty by providing a wet, glossy appearance.

• Applying a sealant protects the paving stones from the harmful effects of different weather elements, like sun, rain, snow, and ice.

• Paver materials are porous. Sealing protects them from discoloration, stains, break marks, accumulated dirt, dust, mold, mildew, grease, and grime. The sealant also repels moisture and prevents water damage, improving drainage around the paved area.

• It makes it more convenient and faster to clean and maintain.

• Reduces cracks and loosening of sand joints which inhibits moss and weed growth between stones.

• It prevents sand loss and keeps pavers joined together to avert shifting, enhancing the structure’s durability.

Cons of sealing paving stones

There are a few downsides of sealing paving stones that homeowners should consider.

• Requires regular re-sealing, depending on the quality of the sealant and paver material.

• High-quality sealants are expensive.

• Sealants break down over time if not applied correctly.

• The application requires specific weather conditions. Applying the sealant on a windy day can harm the adjacent plants and shrubs. 

• Sealant application requires the use of safety gear, like masks, gloves, and shoe covers to avoid inhaling fumes.

There are two types of paving stone sealants—water-based (eco-friendly) and solvent-based. When choosing a sealant, the homeowner will need to consider the type of finish they want (shiny or matte), the lifespan, stain and slip resistance, and cost. Once paving stones are sealed, they require re-sealing every 3-5 years. However, the frequency depends on the foot traffic, type of sealant used, and the exposure to different elements.

Installing pavers spices up the outdoor living space, enhances the home’s curb appeal, and increases its value. They are durable, easy to repair and maintain, and homeowners should consider sealing the paving stones if they want them to look clean and last longer. They can carry out the paving stone sealing or re-sealing process by themselves or hire a professional for the job.
