Penetrating paver sealer is the best type of paver sealer to use if you are looking to reduce damage and deterioration to your paver surface without having to maintain a visible surface film. Penetrating paver sealer is designed to work entirely below the surface and will provide years of life before the need to recoat.
Penetrating Paver Sealer – When Searching for a Penetrating Paver Sealer Which is the Best Paver Sealer for Your Requirement?
You can choose among several options for penetrating paver sealer. You can select a silicate penetrating paver sealer, a silane-siloxane penetrating paver sealer, a silane-acrylic penetrating paver sealer, and a siliconate penetrating paver sealer. Which penetrating paver sealer is best for your application will depend on several factors. Before touching on which penetrating paver sealer is best for your application, let’s touch on what makes a penetrating paver sealer a penetrating sealer.
WHAT DETERMINES HOW DEEP A PENETRATING PAVER SEALER PENETRATES THE CONCRETE?
There are two primary factors that determine how deep a penetrating paver sealer can penetrate the paver surface: the porosity of the paver material and the viscosity of the paver sealer. Think of the concrete like a sponge. From the top to the bottom, the concrete or paver material is made up of tiny holes that allow for water and other liquids to travel from the surface, down into the concrete. The number of the holes in the concrete, and the size of the holes, will determine how much liquid can enter the material, how fast, and how deep. Now, thicker liquids will absorb slower and cannot absorb as deep as thinner liquids; more porous surfaces will absorb liquids faster and deeper than less porous surfaces. Both factors are equally important when choosing a penetrating paver sealer.
WHY IS POROSITY IMPORTANT WHEN IT COMES TO PENETRATING PAVER SEALER?
Now that you understand what determines how deep a penetrating paver sealer penetrates, it is important to touch on why that it is important. If you take two pieces of concrete, one piece being very porous, and one not being very porous, and you apply the same amount of sealer to both, this is what will happen:
- The penetrating paver sealer that is applied to the very porous concrete will absorb throughout the concrete. It will continue to absorb and spread the paver sealer, until it can’t spread any further. Because the sealer will be spread throughout the concrete, much of the pore space will be left open, and therefore, most of the concrete will be left unsealed. Porous paver surfaces will require more material to achieve full, even coverage. As the paver sealer hardens in the pores, or reacts and leaves deposits depending on the type of sealer, the size of the pores will be reduced with each application, and therefore slowing down the absorption and movement of each additional coat. Very porous surfaces will often require more than 2 coats of the penetrating paver sealer to be considered sealed.
- The penetrating paver sealer that is applied to the dense, less porous concrete will slowly absorb through the surface and likely won’t make it very far. Because the paver sealer is slower to absorb and is contained in a smaller area, more of the pore space will be filled faster, slowing down the movement of the sealer even more. Dense, and less porous surfaces will require less material to achieve full, even coverage.
PENETRATING PAVER SEALER – IS PENETRATION DEPTH IMPORTANT FOR PENETRATING PAVER SEALER PERFORMANCE?
When it comes to penetrating paver sealer you would assume that a thicker barrier is better than a thinner barrier, but not so, you have to consider your reason for sealing in the first place. The purpose of a penetrating paver sealer is to reduce damage and deterioration on the surface of the concrete. The further away from the surface the protective barrier is, the less useful that barrier becomes. The quality of the barrier closer to the surface is the most important factor to look at when it comes to choosing a penetrating paver sealer. The deeper the concrete sealer penetrates; the more material will be required to achieve a high quality barrier close to the concrete surface. Now, the only exception to that rule is when it comes to densifiers. Densifiers are designed to increase the strength and density of the concrete, so having a deep, thick barrier is a benefit.
SHOULD I CHOOSE A PENETRATING PAVER SEALER BASED ON HOW DEEP IT CAN PENETRATE?
As mentioned above, when it comes to choosing a penetrating paver sealer, the porosity of the concrete and the viscosity of the sealer determine penetration depth. The porosity of the concrete can’t be determined by a sealer, but viscosity can. Most people can’t tell the difference in viscosity when it comes to concrete sealers because penetrating paver sealers are designed to penetrate the concrete and aren’t designed to be a thick liquid. The chemicals contained in penetrating paver sealers are carried by water or a solvent, both of which are similar. I will touch on how these differences impact your choice of a penetrating paver sealer a little further down.
Types of Penetrating Paver Sealer – Choosing Your Penetrating Paver Sealer Among Available Options
The four main types of penetrating paver sealers are silicate based penetrating paver sealer, Silane-Siloxane based penetrating paver sealer, Silane-Acrylic based penetrating paver sealer, and siliconate based penetrating paver sealer. Each type of penetrating paver sealer provides a different benefit and is designed for specific applications.
Silicate Penetrating Paver Sealer – Silicate paver sealer, also referred to as concrete densifiers and surface hardeners, penetrate the concrete where they chemically react with the free lime and calcium in the concrete to create Calcium Silicate Hydrate (CSH). CSH, which looks like tiny crystals, is formed during the initial curing of the concrete. Silicate sealers simply take the unreacted free lime and calcium and cause it to re-react, filling in more of the pores space with CSH. The more CSH in the pores, the smaller the pores. The smaller the pores, the denser the concrete is, and the stronger the concrete becomes. There are two primary types of silicate sealers, sodium silicate based penetrating paver sealers and lithium silicate based penetrating paver sealers. Both types of silicate sealers spark the same chemical reaction and form the same CSH carrier within the pores. Lithium silicate sealers have a slightly smaller resin and are commonly used for dense surfaces, while sodium silicate densifiers have a slightly larger resin and are commonly used for porous surfaces and in concrete polishing applications.
Silicate Based Penetrating Paver Sealer – Silicate concrete sealers are best for applications where an increase in the strength and density of the concrete are required. If you are experiencing issues with the strength or density of your concrete, a silicate penetrating paver sealer is a great solution. Silicates will help to reduce concrete dusting, and deterioration caused by surface abrasion. Silicates can also slow down the movement of sub-surface water and moisture, but they don’t stop it. They are commonly used in waterproofing applications but should not be used as the primary method of waterproofing. Silicates do not reduce the absorption of surface water however, so if you are looking to reduce damage and deterioration caused by water absorption, or snow and ice, a Silane-Siloxane based penetrating paver sealer will be required instead, or in addition to. If you are applying a silicate penetrating paver sealer and a Silane-Siloxane penetrating paver sealer, you need to wait at least 7 days after you have applied the silicate sealer before you can apply a Silane-Siloxane sealer. Silicate concrete sealers should only be applied to concrete surfaces.

Silane-Siloxane Penetrating Paver Sealer – Silane-Siloxane penetrating paver sealer penetrates the concrete where they chemically react to form a hydrophobic barrier within the pores. The barrier formed will reduce the absorption of water and other liquids, therefore reducing damage and deterioration caused by water absorption. Cracking, spalling, staining, and the growth of mold and mildew are reduced when concrete is sealed with a Silane-Siloxane penetrating paver sealer. Silane-Siloxane penetrating paver sealers are referred to as water repellent paver sealers, but they don’t get their name for the reasons you may think. When you first apply this type of penetrating paver sealer to your concrete, you may get a water bead effect of the surface. While it is a very cool thing to see, it isn’t designed as that, and the visible repellency on the surface will be short lived. When the sealer is first applied it will deposit a hydrophobic barrier in the pores, including the pores that are open and exposed on the surface of the concrete. Surface abrasion will eventually wear down the barrier in the exposed pores and the bead effect will go away. Depending on the porosity of the surface being sealed, you may never get the bead effect. If you do get the bead effect it could last a couple of days, or a couple of months. The benefits of the sealer come from the water repellency and bead effect it offers below the surface. What you may have been privileged to see on the surface temporarily is what is happening in the hundreds of microscopic pores below the surface. Because below the surface aren’t exposed to surface abrasion, the barrier below the surface can last for up to 7-10 years. You will notice that sealed concrete dries faster, is easier to clean, and are easier to keep clean than unsealed concrete. Silane-Siloxane penetrating paver sealer can be applied to concrete, brick, pavers, and natural stone. When it comes to choosing a water based or a solvent based Silane-Siloxane paver sealer, there are a few things to consider:
- Solvent based Silane-Siloxane penetrating paver sealer dries slightly faster than water based (approximately 15-20 minutes faster). They can also be applied in colder temperatures. Water based Silane-Siloxane sealers have strict application temperature restrictions.
- Water based Silane-Siloxane penetrating paver sealer has little to no odor, while solvent based penetrating paver sealer do. The application materials and PPE also varies between water and solvent based sealers.
- If you are applying to a home or building that has surrounding materials sensitive to acetones (i.e., vinyl siding, wood, paint, roofing, etc.), solvent based Silane-Siloxane sealers can be damaging to those materials if they come into contact with them, where-as water-based Silane-Siloxane penetrating paver sealer has no negative chemical reaction, and can be washed off with soap and water.
The chemical reaction between water based and solvent based Silane-Siloxane penetrating paver sealers is identical, so it really comes down to preference, availability of application tools, and environment.

How To Apply A Penetrating Paver Sealer
While it is always best to follow the application instructions of the concrete sealer you are applying, there are a few application rules that remain true for all penetrating paver sealers:
PENETRATING PAVER SEALER CAN ONLY BE APPLIED TO UNSEALED SURFACES.
- Penetrating paver sealer needs to be able to penetrate the concrete and can’t do so if there is a coating on the surface that prevents them from doing so. Some penetrating sealers can be applied to surfaces previously sealed with another type of penetrating paver sealer, but it is best to contact a Foundation Armor technician before doing so.
- Penetrating paver sealer should be applied to a completely clean and dry surface. The concrete should be properly cleaned with a pressure washer, and other necessary spot treatments. If a cleaner was used, it is important to make sure the cleaner has been completely removed. If PH balancing is required, that should also be done as well. Concrete should be allowed to dry at least 24 hours before sealing.
- While all penetrating paver sealers can be applied with a roller or sprayer, sprayers will provide more control over coverage rates, and consistency. Regardless of which application method you choose, be sure to apply an even amount of material to the entire substrate and be careful not to over, or under apply. If the penetrating paver sealer has been under applied, it won’t work to its full potential. If the penetrating paver sealer has been over applied, dark spots, white spots, or films may appear that can’t always be removed.
- Ensure that the concrete can easily absorb water before sealing. If you dump a cup of water on the concrete, and the water doesn’t quickly and easily absorb into the concrete, then a sealer will have issues penetrating the concrete. If water doesn’t quickly and easily absorb into the concrete, contact a Foundation Armor technician before applying.

Best Penetrating Paver Sealer for Driveways: The best penetrating paver sealer for a driveway is a Silane-Siloxane paver sealer. While a silicate paver sealer can also be used if the driveway is showing signs of dusting, a Silane-Siloxane sealer will offer the most benefit in terms of protection against water and the outside elements. Silane-Siloxane penetrating paver sealers are the best penetrating paver sealer to use on concrete, brick, paver, and natural stone driveways.
Best Penetrating Paver Sealer for Walkways or Patios: The best penetrating paver sealer for a walkway or patio is a Silane-Siloxane concrete sealer. Like with driveways, silicate concrete sealers can be used if the walkway or patio is showing signs of deterioration, but a Silane-Siloxane sealer will offer the most protection against water absorption and exposure to the elements.
Best Penetrating Paver Sealer Pool Deck: The best penetrating paver sealer for a pool deck is a Silane-Siloxane concrete sealer. Pool decks are exposed to large amounts of water, making water-repellent sealers the best choice for protecting pool decks against water absorption.
Best Penetrating Paver Sealer for Brick Walls or Chimneys: The best penetrating paver sealer for a brick wall or chimney is a Silane-Siloxane concrete sealer. Silane-Siloxane sealers will offer the most protection against water absorption and exposure to the elements.

Best Penetrating Paver Sealer for Basement, Garage, and Warehouse Floors: If the concrete is going to be polished, or if the concrete is showing signs of dusting or deterioration, a concrete densifier may be the best option as your penetrating paver sealer. If the concrete isn’t going to be polished, and isn’t showing signs of dusting and deterioration, a Silane-Siloxane penetrating paver sealer may be best. If the concrete is already polished however, that will limit what can be applied. For any questions relating to these applications, it is best to contact a Foundation Armor technician before purchasing.
Best Penetrating Paver Sealer by Surface Type
Concrete: The best penetrating paver sealer for concrete will depend on the current condition of the concrete, and what you need the concrete sealer to offer in terms of performance. Most penetrating paver sealers can be applied to concrete.
Brick: Silane-Siloxane sealers and Silane-Acrylic sealers can be applied to brick surfaces, but silicate concrete sealers and siliconate concrete sealers can’t. If you apply a silicate concrete sealer or a siliconate concrete sealer to brick, you will end up with white crystals or white deposits on the surface that may be permanent.
Pavers: The best penetrating paver sealer for pavers is a Silane-Siloxane concrete sealer or a Silane-Acrylic penetrating paver sealer. While concrete densifiers can sometimes be applied to pavers, the chances are high that they may leave white crystal deposits on the surface that can’t be removed. Siliconate sealers also can’t be applied to pavers because they will leave white deposits on the surface that are very hard to remove.
Flagstone: A Silane-Siloxane penetrating paver sealer and A Silane-Acrylic penetrating paver sealer can be applied to flagstone surfaces, but silicate concrete sealers and siliconate concrete sealers can’t. If you apply a silicate penetrating paver sealer or a siliconate penetrating paver sealer to flagstone, you will end up with white crystals or white deposits on the surface that may be permanent.
Slate and Bluestone: Silane-Siloxane penetrating paver sealer and Silane-Acrylic penetrating paver sealer can be applied to slate and bluestone surfaces, but silicate concrete sealers and siliconate concrete sealers can’t. If you apply a silicate concrete sealer or a siliconate concrete sealer to slate or bluestone, you will end up with white crystals or white deposits on the surface that may be permanent.
Natural Stone: Silane-Siloxane penetrating paver sealer and Silane-acrylic penetrating paver sealer can be applied to natural stone surfaces, but silicate concrete sealers and siliconate concrete sealers can’t. If you apply a silicate concrete sealer or a siliconate concrete sealer to natural stone, you will end up with white crystals or white deposits on the surface that may be permanent.
Penetrating Paver Sealer Limitations
Penetrating paver sealers are a fantastic choice for most paver applications, but they aren’t always the best choice. Some concrete applications will require more than what a penetrating paver sealer can offer. Here are a few limitations when choosing a penetrating paver sealer:
- A penetrating paver sealer can’t stop oil stains.
- A penetrating paver sealer can’t stop hot tire marks.
- A penetrating paver sealer can’t stop staining.
- A penetrating paver sealer can’t stop deterioration caused by surface abrasion.
When a penetrating paver sealer is used, the surface of the concrete is left exposed, leaving the surface susceptible to staining and deterioration caused by surface abrasion. A penetrating paver sealer is best used for reducing damage. The only way to stop staining and deterioration is with a coating that is designed to put a protective layer between the concrete and what comes into contact with the surface. Acrylic sealers are popular coating options for exterior concrete, and waxes and urethanes are popular options for interior concrete.
Things That Become Noticeable When a Penetrating Paver Sealer Is Applied
Once you seal your pavers, you will start to notice things that you didn’t notice before. While the penetrating paver sealer itself isn’t noticeable because there isn’t a film or coating, the functionality of the coating becomes clear. With concrete densifiers, you will notice less dusting, but with Silane-Siloxane sealers, you will notice several things:
- When your paver surface is sealed with a penetrating paver sealer you will notice that ice starts to form on the surface, instead of in the surface. Silane-Siloxane sealers reduce the absorption of water, keeping water and other liquids closer to the surface. The sealer will reduce water that is allowed to freeze in the pores and force it to freeze on the surface.
- When your paver surface is sealed with a penetrating paver sealer you will find that it dries faster than unsealed surfaces. Silane-Siloxane penetrating paver sealers force water to stay closer to the surface so that it can evaporate faster.
- When your paver surface is sealed with a penetrating paver sealer will find that the growth of mold and mildew on the surface is reduced. Mold and mildew need moisture to grow. Silane-Siloxane penetrating paver sealer keeps water closer to the surface so that it can evaporate faster. Unsealed areas that would remain saturated with water for longer periods of time, will dry faster, reducing the amount of moisture that will hang around and grow mold and mildew.
- When your paver surface is sealed with a penetrating paver sealer you will find the pavers are easier to clean and keep clean.
- When your paver surface is sealed with a penetrating paver sealer you will find your pavers look better, longer.
- When your paver surface is sealed with a penetrating paver sealer you may notice pollen, clay, iron, and minerals more. Silane-Siloxane sealers reduce the absorption of water, and water is common carrier of pollen, clay, iron, and other minerals. Unsealed surfaces will absorb many of these impurities, but because water is kept closer to the surface with sealed surfaces, once the water evaporates pollen, clay, iron, and minerals will be left on the surface allowing you to clean them off the surface before they have the ability to bond very easily. Silane-Siloxane sealers buy you time to clean your surface, but if you don’t clean your surface, the impurities will bond to the surface once the water evaporates. Now that the impurities are made visible, it is important to clean them so they don’t become a problem.
How Do I Know When It Is Time To Reseal With A Penetrating Paver Sealer?
When to reseal your paver driveway, walkway, patio or pool deck with a penetrating paver sealer depends on the type of penetrating paver sealer you used. Here are a few things to consider when resealing your concrete:
Silicate Penetrating Paver Sealer – The CSH formed from the chemical reaction caused by the silicate sealer is permanent. It can never be removed. Additional silicate sealer can be applied to surfaces sealed with a silicate sealer, but it is best to apply to a test area first. If silicate sealer is over applied, CSH will form on the surface and can only be removed by mechanically grinding the concrete.
Silane-Siloxane Penetrating Paver Sealer – Silane siloxane penetrating paver sealer can provide up to 7-10 years of life before the need to reseal, but many people choose to reseal sooner. If it has been a few years and the concrete quickly and easily absorbs water, it is likely safe to apply another coat – just be careful not to over apply. Silane-Siloxane paver sealers are water repellent sealers so there are more risks to applying a fresh coat of a water-based silane-siloxane paver sealer too soon. Typically, if the concrete can quickly and easily absorb water, it is safe to reapply with a water-based Silane-Siloxane, but if you have questions about reapplication, don’t hesitate to contact a Foundation Armor technician.
Silane-Acrylic Penetrating Paver Sealer – Silane-Acrylic penetrating paver sealer can last up to 5-7 years before the need to reseal, but if the color enhancement has faded and you want to apply a fresh coat, you can do so because Silane-Acrylic sealers are solvent based and self-priming.
Siliconate Penetrating Paver Sealer – Siliconate penetrating paver sealer can last up to 3-5 years before the need to reseal, but you can choose to reseal sooner. If it has been a few years and the concrete quickly and easily absorbs water, it is likely safe to apply another coat – just be careful not to over apply or you will end up with white silicone deposits on your concrete that are hard to remove. If you aren’t sure which penetrating paver sealer is best for sealing or resealing your concrete, brick, pavers, or natural stone, please don’t hesitate to reach out a Foundation Armor technician before purchasing!
