Comparison Summary
The shortlist separates into four useful groups. Foundation Armor Armor SX5000 WB is the strongest natural-look choice because its water-based silane-siloxane formula is designed to work below the surface across concrete, brick, pavers and several types of natural stone. MasonryDefender Patio Paver Sealer is the better fit when low gloss and joint-sand stabilization matter. For visible color enhancement, Foundation Armor Armor AR350 offers a low-gloss wet look, while Armor AR500 raises the finish to high gloss. DOMINATOR LG+ is attractive for concrete pavers and decorative concrete when higher stated coverage and a fast-dry, low-VOC application are priorities. Armor WB25 is a specialized high-gloss cure-and-seal for concrete and concrete pavers, but its exclusions for clay brick, flagstone, slate and natural stone are decisive. SEK Surebond SB-1300 G covers the natural-matte and joint-sand niche, while Black Diamond Stoneworks provides water-based high-gloss flexibility for several indoor and outdoor masonry surfaces. Always confirm the exact substrate, existing coating, VOC variant and number of coats before buying.
Buying Guide
Sizing and Capacity
Choose the container size from the measured area, the stated coverage and the number of coats—not from the product name alone. The Foundation Armor 5-gallon options provide enough material for substantial areas, but the listed 175–225 square feet per gallon still means roughly 875–1,125 square feet before accounting for porosity, waste or additional coats. The one-gallon Armor AR350 is better suited to a small patio, walkway section or test area than a full driveway. DOMINATOR LG+ lists 250–400 square feet per gallon per coat on concrete pavers or decorative concrete, while MasonryDefender lists 75–150 square feet per gallon and may need a second coat. Coverage is not interchangeable across products: porous, textured or jointed surfaces generally consume more material, and a two-coat application changes the total requirement substantially.
Feature Tradeoffs
Penetrating and film-forming sealers solve different problems. Armor SX5000 WB is the clearest choice when the current color and texture should remain unchanged; its below-surface approach avoids adding gloss or a visible coating. Acrylic products such as Armor AR350, Armor AR500, Armor WB25, DOMINATOR LG+ and Black Diamond Stoneworks are appearance products as well as protective products, adding low-gloss, wet-look or high-gloss enhancement. Gloss makes color more prominent, but it is less appropriate when a natural finish is the priority. Joint-sand products such as MasonryDefender and SEK Surebond SB-1300 G add a sand-stabilizing purpose that a general water repellent may not provide. A wet-look film may also change how a surface feels when wet, so sloped or pool-deck areas deserve a small test patch and careful attention to the product instructions.

Key Specs to Compare
Start with substrate: concrete pavers, poured concrete, brick, clay brick, flagstone, slate and natural stone are not one interchangeable category. Armor WB25 has particularly important exclusions, while Armor SX5000 WB has the broadest stated masonry compatibility in this group. Next compare finish: natural, matte, low gloss, wet look or high gloss. Then check chemistry and handling. Water-based options generally offer lower odor or easier cleanup in the supplied descriptions, while the Armor AR350 and AR500 variants here are solvent-based 700 VOC products. Compare coverage per gallon, whether the figure applies per coat, the recommended number of coats, application tool and drying or recoat windows. Finally, check whether joint-sand stabilization, water repellency, color enhancement or a cure-and-seal function is the actual priority.
Setup and Handling Considerations
A clean, dry and properly prepared surface is the common starting point. Product information for the Armor sealers calls for a completely clean and dry surface, and the WB25 guidance includes at least 24 hours of drying after water or pressure washing. Use a pump sprayer for Armor SX5000 WB; its application method is different from products that support a roller, brush or general sprayer. MasonryDefender calls for a pump-up sprayer and back brushing for even application. Before covering the full project, confirm that the existing coating is compatible, test an inconspicuous area for color and gloss, and plan around the product’s temperature, drying and recoat requirements. Do not assume that a low-odor or water-based formula eliminates the need to protect adjacent surfaces or follow the label.
Maintenance and Longevity
Maintenance expectations depend heavily on whether the product forms a surface film. Armor SX5000 WB is described as working below the surface, with no surface film to maintain, and the manufacturer states protection may last up to 7–10 years. Armor WB25 is described as lasting up to 1–3 years in residential and commercial applications, while the AR350 listing describes a long-lasting finish designed to last for years and says resealing can use a single coat on a clean, dry surface. These are manufacturer-stated expectations, not guarantees for every climate, traffic level or substrate. Film-forming wet-look products should be inspected for uneven wear, loss of sheen or incompatible previous coatings before recoating. Clean the surface according to the selected product’s instructions rather than applying a new layer over dirt, trapped moisture or failing sealer.
Reliability Signals
The most useful reliability signals are exact model identification, clear substrate limits, stated application tools and consistent coverage or drying instructions. Verify the full variant name: Armor AR350 and Armor AR500 are available in different VOC formulations, and the supplied AR350 products are specifically the 700 VOC versions. A product that clearly identifies whether it is penetrating, acrylic, water-based, solvent-based, high gloss or low gloss is easier to match to the project than a generic waterproofing label. Also treat a broad marketing phrase such as “all outdoor surfaces” cautiously unless the exact listing names your substrate. A precise exclusion, such as WB25’s restriction against natural stone and clay brick, is useful information rather than a flaw.
How to Compare Reviews
When comparing product-page comments, separate exact models and sizes before drawing conclusions. Do not combine Armor AR350 with Armor AR500, a one-gallon package with a 5-gallon package, or a natural-look penetrating sealer with a gloss acrylic simply because the brand is the same. Look for comments tied to the same substrate, finish and application method: concrete pavers versus natural stone, one coat versus two, pump sprayer versus roller, and new versus previously sealed surfaces. Give greater weight to observations that explain preparation, weather, drying and final appearance than to short comments that only describe color or packaging. A review about a high-gloss product cannot answer whether a natural-look sealer preserves the original appearance.
Common Mistakes
The most expensive mistakes are usually compatibility mistakes. Do not use Armor WB25 on clay brick, flagstone, slate or natural stone, and do not assume a concrete-paver sealer is automatically suitable for every masonry surface. Do not choose high gloss when the goal is an unchanged natural appearance, or choose a penetrating product when visible color enhancement is essential. Do not calculate the container size from one coat if the directions call for two. Do not ignore the 700 VOC designation on the supplied AR350 and AR500 variants. Applying over a damp or poorly cleaned surface can create uneven results, while using the wrong sprayer or skipping a test patch can make a full-area correction difficult. Finally, do not assume every sealer stabilizes joint sand; choose a product whose listing specifically supports that purpose when it is central to the project.
Frequently Asked Questions
Which paver sealer best preserves the existing color and texture?
Foundation Armor Armor SX5000 WB is the strongest match among these options. It is a water-based penetrating silane-siloxane sealer for unsealed concrete, brick, pavers, bluestone, flagstone, slate, natural stone and masonry, and the manufacturer says it will not change the look, color or feel. It will not create a wet-look or glossy finish.
What is the best choice for a wet-look finish on concrete pavers?
Choose between low gloss and high gloss first. Armor AR350 is the stronger low-gloss wet-look option, while Armor AR500 and Armor WB25 provide high-gloss finishes. DOMINATOR LG+ is another low-gloss choice for concrete pavers and decorative concrete, with higher stated coverage per gallon. Confirm the surface and VOC requirements before selecting an acrylic.
Can I use a concrete-paver sealer on natural stone or clay brick?
Not automatically. Armor WB25 specifically excludes clay brick, red Chicago pavers, flagstone, slate and natural stone. Armor SX5000 WB and DOMINATOR Low Gloss Wet Look Paver Sealer list broader masonry or natural-stone compatibility, but the exact surface should still be confirmed on the product information before application.
Which options can help stabilize joint sand?
MasonryDefender Patio Paver Sealer and SEK Surebond SB-1300 G are the clearest joint-sand choices in this group. MasonryDefender specifically describes joint sealing and sand lock, while SEK Surebond is described as bonding joint sand and reducing sand loss. A general penetrating water repellent or gloss acrylic should not be assumed to provide the same function.
How much sealer should I buy for a patio?
Measure the actual surface, then divide by the product’s stated coverage per gallon and account for the required coats. Armor products list approximately 175–225 square feet per gallon, MasonryDefender lists 75–150, and DOMINATOR LG+ lists 250–400 per gallon per coat on suitable concrete pavers or decorative concrete. Porosity, texture, joints and application waste can reduce the practical coverage.
Final Recommendation
Foundation Armor Armor SX5000 WB is the best overall paver sealer for buyers who want broad masonry compatibility and protection without changing the existing appearance. Its penetrating, water-based formula is especially well suited to unsealed concrete, brick, pavers and natural stone. Choose MasonryDefender Patio Paver Sealer instead when stabilizing joint sand and maintaining a low-gloss finish are more important. For visible color enhancement, choose Armor AR350; for high gloss on compatible concrete or pavers, choose Armor AR500 or Armor WB25, with WB25 reserved for surfaces within its specific compatibility limits.
