Should Flagstone Be Sealed?

Flagstone is a popular choice for patio areas due to it’s natural beauty and durability. However, one question that often arises is whether or not flagstone should be sealed. The answer is yes, all new flagstone for patios should be sealed to fill in the pores within the stone to repel spills and prevent staining. Sealing the flagstone helps to maintain it’s appearance and extend it’s lifespan.

When it comes to selecting a sealer for flagstone, it’s important to choose one that will provide adequate protection without compromising the natural look and feel of the stone. Glossy finish sealers may give the stone a shiny appearance, but they can also make it look artificial and take away from it’s natural beauty. Instead, it’s recommended to choose a sealer that features a penetrating acrylic with a matte finish. This type of sealer will allow the stone to breathe while still providing protection against spills and stains.

A quality sealer will create a barrier on the surface of the stone, causing water to bead up and roll off instead of being absorbed by the stone. This can be especially important in outdoor environments where the flagstone is exposed to rain and other forms of moisture.

The sealer creates a barrier that prevents these substances from seeping into the porous surface of the stone, making it easier to clean and maintain the patio area. This can be particularly beneficial for outdoor dining areas or areas where there’s a higher risk of spills and stains.

It’s important to note that sealing flagstone isn’t a one-time process. While the initial sealing provides immediate protection, it’s necessary to periodically reapply sealer to maintain the stones resistance to water and stains. The frequency of sealing will depend on various factors such as the type of sealer used, the amount of foot traffic or usage the area receives, and the climate conditions. It’s recommended to consult with a professional or the sealer manufacturer for guidance on how often to reseal the flagstone.

In order to maintain the natural beauty and durability of flagstone, it’s important to exercise caution when pressure washing. While it can effectively remove dirt and grime, excessive pressure or the use of harsh chemicals can potentially cause damage to the surface of the stone. This article explores the potential risks associated with pressure washing flagstone and offers alternative methods for cleaning and maintaining it’s appearance.

Does Pressure Wash Damage Flagstone?

Flagstone is a beautiful natural stone that adds an elegant touch to any outdoor space. However, when it comes to pressure washing, caution must be exercised because improper techniques can damage flagstone. Unlike poured concrete pavers, flagstone is naturally occurring and can have various impurities that might not be visible to the naked eye. Extreme or harsh power washing can worsen these impurities, resulting in an unpolished appearance and even potential breakage.

The force of high-pressure water can be detrimental to flagstone, especially if the pressure is too intense or directly aimed at one spot for an extended period. It can chip, crack, or erode the stone surface, affecting it’s structural integrity and aesthetic appeal. Additionally, if the pressure washing nozzle is held too close to the flagstone, it can create deep gouges or depressions, leaving irreversible damage.

Furthermore, the use of harsh chemicals during power washing can also harm flagstone. While some detergents may be suitable for certain types of stone, they can react negatively with impurities found in flagstone. This chemical reaction might result in discoloration, etching, or a dull appearance, compromising the natural beauty of the stone.

Soft washing utilizes specialized detergents and a low-pressure spray to effectively remove dirt and grime without risking damage to the stone. Additionally, manually scrubbing the flagstone with a soft-bristle brush and mild soap can also achieve satisfactory cleaning results.

Sealing natural stone pavers is a common practice to prevent staining and odors. However, when it comes to using paver sealer on natural stone, there are a few things to consider. Natural stone is porous and can react differently to certain sealers. Therefore, it’s important to choose a sealer specifically designed for natural stone to ensure optimal protection and longevity.

Can You Use Paver Sealer on Natural Stone?

Yes, you can use a paver sealer on natural stone. Natural stone is a beautiful and durable material that’s commonly used for outdoor flooring. However, it’s also porous and can be susceptible to staining and odors if not properly sealed. A paver sealer acts as a protective barrier that prevents liquids, oils, and other substances from penetrating the stones surface, making it easier to clean and maintaining it’s appearance.

Sealing the stone can bring out it’s natural colors and patterns, making it more vibrant and visually appealing. Additionally, a sealer can provide an added layer of UV protection, preventing the stone from fading or discoloring over time due to exposure to sunlight.

Properly maintaining and sealing your natural stone pavers will help extend their lifespan and ensure that they continue to look beautiful and withstand the elements for years to come.
