Flagstone, with its rustic beauty and natural charm, has been a popular choice for outdoor spaces and landscaping projects for centuries. However, its porous nature makes it prone to staining, weathering, and erosion, which can lead to a dull, faded appearance over time. This is where a good flagstone sealer comes into play, protecting your investment and preserving its original beauty. But with so many products on the market, it can be overwhelming to choose the right one. In this article, we’ll delve into the world of flagstone sealers, exploring the different types, benefits, and factors to consider when selecting the best product for your needs.
Understanding Flagstone and Its Sealing Needs
Before diving into the world of sealers, it’s essential to understand the characteristics of flagstone and why it requires sealing. Flagstone is a type of sedimentary rock, composed of sand, silt, and clay particles. Its natural porosity makes it susceptible to absorbing water and stains, which can lead to:
- Color fading and discoloration
- Water damage and erosion
- Stain accumulation and spotting
- Weeds and moss growth
Sealing flagstone helps to:
- Protect it from water and stain damage
- Enhance its color and appearance
- Maintain its texture and integrity
- Reduce maintenance and cleaning efforts
Types of Flagstone Sealers
Flagstone sealers can be broadly categorized into two types: topical sealers and penetrating sealers.
Topical Sealers
Topical sealers, also known as coatings, form a physical barrier on the surface of the flagstone. They provide a glossy finish and are often used to enhance the appearance of the stone. However, they can:
- Alter the natural appearance of the stone
- Create a slippery surface
- Peel or flake off over time
Examples of topical sealers include:
- Acrylic sealers
- Urethane sealers
- Wax-based sealers
Penetrating Sealers
Penetrating sealers, also known as silica-based sealers, absorb into the stone, reacting with the calcium carbonate to form a hydrophobic (water-repelling) barrier. They:
- Penetrate deep into the stone, providing long-lasting protection
- Maintain the natural appearance of the stone
- Do not create a slippery surface
Examples of penetrating sealers include:
- Silane-modified polyethers (SMP)
- Siloxane-based sealers
- Fluoropolymer-based sealers
Factors to Consider When Choosing a Flagstone Sealer
With so many products on the market, it’s crucial to consider the following factors when selecting a flagstone sealer:
Performance and Protection
- Look for a sealer that provides long-lasting protection against water, stains, and UV rays.
- Check if the sealer is breathable, allowing moisture to escape while preventing water from entering.
Appearance and Finish
- Consider the desired finish: matte, satin, or glossy.
- Ensure the sealer does not alter the natural appearance of the stone.
Compatibility and Safety
- Check if the sealer is compatible with the specific type of flagstone you have.
- Ensure the sealer is non-toxic, non-corrosive, and environmentally friendly.
Application and Maintenance
- Consider the ease of application: spray, roll, or brush.
- Look for a sealer that is easy to maintain and clean up.
Manufacturer’s Reputation and Warranty
- Research the manufacturer’s reputation and customer reviews.
- Check if the sealer comes with a warranty or guarantee.
Price and Value
- Compare prices among different products and manufacturers.
- Consider the cost per square foot and the overall value provided.

What is flagstone sealer and why do I need it?
Flagstone sealer is a type of protective coating applied to flagstone surfaces to prevent damage from various environmental factors. It’s a vital component of flagstone maintenance, as it helps to repel water, resist stains, and reduce the risk of etching. Without a sealer, flagstone can become permeable to water, dirt, and other substances, leading to discoloration, cracking, and other forms of damage.
By applying a high-quality flagstone sealer, you can ensure your flagstone surfaces remain protected and maintain their natural beauty for years to come. Additionally, a sealer can make cleaning and maintenance easier, as it prevents dirt and stains from penetrating the surface. This means you can enjoy your outdoor spaces without worrying about the integrity of your flagstone surfaces.
What are the different types of flagstone sealers available?
There are two primary types of flagstone sealers: topical and impregnating. Topical sealers form a physical barrier on the surface of the flagstone, creating a layer of protection against water, stains, and other forms of damage. They are often available in a variety of finishes, from matte to high-gloss, and can enhance the appearance of the stone. Impregnating sealers, on the other hand, penetrate deep into the pores of the flagstone, providing long-lasting protection without altering the appearance of the stone.
When choosing a flagstone sealer, it’s essential to consider the specific needs of your surface. If you want to enhance the appearance of your flagstone, a topical sealer may be the better choice. However, if you prioritize durability and protection, an impregnating sealer is likely the way to go. Be sure to read product labels carefully and follow application instructions to ensure the best results.
How do I choose the best flagstone sealer for my project?
Selecting the best flagstone sealer for your project involves considering several factors, including the type of flagstone, the level of traffic, and the desired level of protection. It’s also crucial to research different products, reading reviews and product labels to understand their specific characteristics and benefits. Look for sealers that are specifically designed for flagstone, as they will provide the best protection and results.
It’s also important to consider the color and finish of your flagstone, as some sealers can enhance or alter the appearance of the stone. Be sure to test a small, inconspicuous area of the flagstone before applying the sealer to ensure the desired results. Additionally, consider the level of maintenance you’re willing to commit to, as some sealers require more frequent reapplication than others.
How often should I seal my flagstone surfaces?
The frequency of sealing flagstone surfaces depends on several factors, including the type of sealer used, the level of traffic, and the exposure to the elements. As a general rule, it’s recommended to reapply a topical sealer every 1-2 years, as they tend to wear off over time. Impregnating sealers, on the other hand, can last for 5-10 years or more before needing to be reapplied.
It’s essential to monitor the condition of your flagstone surfaces and reapply the sealer as needed. Look for signs of wear, such as fading, cracking, or discoloration, and consider reapplying the sealer if you notice any of these changes. Regular maintenance and reapplication can help extend the life of your flagstone surfaces and keep them looking their best.
Can I apply a flagstone sealer myself or should I hire a professional?
Applying a flagstone sealer can be a DIY-friendly project, but it’s essential to follow the manufacturer’s instructions and take necessary precautions to ensure the best results. If you’re comfortable with the process and willing to invest the time and effort, you can achieve professional-looking results.
However, if you’re short on time, lack experience with sealing flagstone, or have a particularly large or complex surface to cover, it may be better to hire a professional. A professional contractor will have the necessary expertise and equipment to ensure a successful application, and they can also provide valuable guidance on the best sealer to use for your specific project.
Are flagstone sealers safe for my plants and pets?
Most flagstone sealers are safe for plants and pets, but it’s essential to choose a product that is specifically labeled as “plant-safe” and “pet-friendly.” Some sealers may contain chemicals that can harm plants or pets, so it’s crucial to read product labels carefully and follow application instructions.
Before applying a sealer, make sure to remove any plants or pet toys from the area, and consider applying the sealer in a well-ventilated area to minimize the risk of exposure. It’s also a good idea to perform a small test patch on an inconspicuous area of the flagstone before applying the sealer to the entire surface.
Can I use a flagstone sealer on new flagstone surfaces?
Yes, it’s possible to use a flagstone sealer on new flagstone surfaces, but it’s essential to wait until the surface is fully cured before applying the sealer. This can take anywhere from 30 days to several months, depending on the type of flagstone and environmental conditions.
Applying a sealer too soon can trap moisture beneath the surface, leading to damage and discoloration. Instead, allow the flagstone to fully cure, then apply the sealer according to the manufacturer’s instructions. This will ensure a strong bond between the sealer and the flagstone, providing long-lasting protection and beauty.
