The best paver sealers help lock stones in place, limit erosion inside joints, repel stains, and keep the pavers looking their best. Sealers cure to a variety of finishes, including wet or high-gloss, matte, or satin. By penetrating deep and filling pores, holes, and crevices, paver sealers protect the substrate material while preventing dirt, insects, or other debris from settling into the stone or brick.
This guide shares what you need to know about the different types of paver sealers, so you can select one of the best paver sealer options for your specific needs.

Types of Best Paver Sealers
Paver sealers help keep paver stones looking new. They also offer additional benefits, including inhibiting moss, weeds, and grass from growing inside the joints; loss of sand from the joints; and blocking stains, such as grease, oil, or gasoline. The best paver sealers also help protect against costly and unattractive damage and deterioration.
While paver sealers are made in a variety of styles and options, the two primary types are non-film-forming paver sealers and film-forming sealers. The type of paver sealer chosen depends on the reason for sealing.
- Non-film-forming paver sealers offer substantial protection, often lasting longer than their film-forming counterparts. They cure to a matte finish.
- Film-forming paver sealers provide more comprehensive protection by creating a physical barrier on top of the paver. Film-forming sealers, which come in satin, gloss, and semi-gloss finishes, require more frequent reapplications.
Solvent-Based
Both water- and solvent-based paver sealers protect against outdoor surface wear. Typically ultraviolet- and stain-resistant, they are reasonably easy to apply. All sealers contain volatile organic compounds (VOCs), which can photo-react when exposed to sunlight, creating low-level ozone that’s a primary ingredient in smog.
Solvent-based sealers, which are generally made from an acrylic/polymer blend, will provide a thickness and coating level that varies depending on the sealer’s percentage of solids. Solvent-based sealers usually offer a thicker, higher gloss appearance than water-based sealers.
Solvent-based sealers contain a high amount of VOCs, dry to a wet finish, and have a strong odor. Cleanup is more complex. If sealer remains after the job, users must spray it back into the original canister and reseal the pour spout. Add xylene to the excess sealer because it can dissolve compounds that water cannot. Dispose of rags and extra solvent in accordance with local or municipal waste management regulations.
Water-Based
Like solvent-based, water-based sealers also are made of acrylic/polymers, but they have one key difference: The polymers are dispersed within water molecules.
When water-based sealer is applied to the pavers, the water molecules begin to evaporate, causing the polymer particles to move closer together. As the water continues to evaporate, the polymer particles eventually fuse, creating a surface barrier that protects the paver stones.
Water-based sealers can appear milky or white during application because of the way polymer particles scatter visible light. They dry to a clear finish.
Unlike solvent-based paver sealers, water-based sealers contain low VOCs, dry to a matte finish, are non-flammable, emit only a mild odor, and are easy to clean up.
Breathable
“Breathability” refers to the sealer’s ability to allow moisture vapors to move through the stonework after sealing. If a sealer is breathable, moisture is less likely to get trapped below the surface.
Acrylics
Acrylic paver sealers, either solvent- or water-based, offer the most comprehensive ultraviolet (UV) resistance.
Acrylic sealants can be breathable, depending on their solid content. Sealers with solids of 15 percent or lower are more breathable than sealers with 20 percent solids, while over 30 percent or more solid content means the sealant is not considered breathable.
Matte-finish sealers are considered breathable because they don’t form a film. Acrylic sealers form a film that dries to a wet or high-gloss finish.
Wet Look
“Wet look” refers to a finish that makes paver stones look darker, as if it had recently rained. Achieve this kind of look by using a paver sealer with a higher acrylic or polyurethane concentration. The greater the concentration, the wetter the finish. Paver sealers that contain 25 percent acrylic or polyurethane content provide a semi-gloss finish, while a sealer that’s 30 percent solid or higher produces a high-gloss wet look.
What to Look for When Buying the Best Paver Sealers
To find the best paver sealer for your project, consider its finish, slip or non-slip; the cost of sealing; drying time; and durability and endurance.
Finish
Finish refers to the final appearance after the paver sealer has been applied and cured.
Finishes can be broken into several categories, including matte finish or natural-look penetrating sealers, low- or high-gloss wet-look sealers, and satin-finish sealers.
For a more natural finish, a penetrating paver sealer probably works best. Penetrating sealants go deep into the stonework or masonry, chemically reacting beneath the surface to protect the paver stones. Penetrating sealers offer a natural look because they don’t form a film and typically don’t alter the pavers’ appearance.
Non-Slip
Depending on the sealer, pavers may have a slippery surface, especially when wet. This can occur after the application of high-gloss or wet-look paver sealant.
When choosing a sealant, consider its slip. Non-slip, breathable paver sealers are a common choice for areas near pools or other high-traffic areas. Low-traffic areas that offer visual appeal, such as a retaining wall, may benefit from a high-gloss sealant.
Some paver sealers, upon the application of a high-gloss or wet-look sealer, have a “slippery-when-wet” look when dry. To use a wet-look sealer in a high-foot-traffic area, increase traction by adding a non-slip additive before applying the paver sealer. Non-slip additives, which work only with film-forming sealers, are most effective when used on a second coat.
Cost
To calculate the cost of sealing paver stones, start by determining the overall square footage of the area. Next, consider the location of the paver stones as well as ease of access.
Other cost-impacting factors include the type of paver. Some paver materials benefit from specific sealant types. Moreover, the pavers’ absorbency level affects the amount of sealer needed. If your paver stones are highly porous, expect to use more sealer than on less absorbent pavers in a similar-size area.
Life Expectancy
The best paver sealers last between three and five years. However, some factors, such as maintenance, traffic, and weather, can impact the sealant’s longevity. These can shorten the pavers’ overall life span.
Use a film-forming sealer to conceal signs of wear on paver stones. A non-film forming sealant cannot hide the telltale signs of aging as well.
Changes in stone color caused by rain can indicate thinning in the paver sealant. However, in heavy or extreme rain conditions, even the most recently applied sealant can darken for a day or so until the water evaporates from the surface.
Drying Time
While climate can affect drying time, most paver sealers dry in 24 hours; some can dry in six hours. The sealant dries when enough solvent has evaporated from the sealer that the stones are no longer tacky.
Curing, on the other hand, occurs when the solvents have not only discharged from the sealer, but also have fused with the oxygen in the air. Fully cured paver sealers have hardened into their final stage and are resistant to damage. While most sealers dry within 24 hours, curing can take anywhere from seven to 30 days.
Penetration
Penetrating sealers go deep into concrete or masonry and fill any holes or other spaces. They protect the substrate material while preventing dirt, debris, or insects from causing damage.
Substrates
The stabilizing layer beneath the paver stones, which typically consists of large amounts of crushed gravel that varies from ¾ inch down to dust, is called the substrate. On walkways, the substrate is generally between 4 to 6 inches beneath the pavers. Driveways typically require 8 to 12 inches.

Tips for Using the Best Paver Sealer
Getting the best results with your paver sealer depends on how the sealer is applied.
- Once work begins, don’t stop. Letting an area dry before the entire area is completely sealed can affect the appearance of the finished pavers and cause the surface to look splotchy or uneven.
- An application sprayer can help speed the application of sealer, ensuring no area remains untouched. It also makes the application considerably easier with less cleanup.
- When applying the paver sealer, keep applying until you reach the saturation point. Ensure that the pavers are wet and that the crevices and spaces are filled. Follow up by using a dry roller to soak up excess sealant and eliminate drip marks.
- Read the manufacturer’s instructions. While most sealants work in a similar manner, read the instructions to discover any quirks or other specifics with that particular brand.
