The best driveway sealer depends on the surface and finish you want: Black Jack Drive-Maxx 1000 is the asphalt option for small cracks and repeated heavy-vehicle use; Armor AR350 is for concrete or pavers with a low-gloss wet look; Armor AR500 offers a high-gloss finish; MasonryDefender protects concrete without changing its appearance. NIEFARG is a crack-repair product, not a full-driveway sealer, so consider it for surface-crack preparation rather than whole-surface protection. The supplied product details do not include ratings, so these recommendations compare stated uses and features instead.

| NIEFARG Crack Filler | Repairing common surface cracks before sealing | Crack repair |
Black Jack Drive-Maxx 1000 Asphalt Sealer
Best for: Homeowners with worn asphalt who want a combined filler and sealer for small cracks. This 5-gallon product is described as a 10-year premium formula, with sand particles intended to help fill small cracks and a latex polymer formula designed to withstand repeated use by heavy vehicles.
It is the most directly targeted choice here for an asphalt driveway. Choose it if the surface is blacktop and you need a sealer that also addresses minor cracks. It is not a substitute for patching larger cracks or potholes; the product information recommends using a separate crack sealant or asphalt patch first. Do not select it for concrete or pavers.
Armor AR350 Low-Gloss Concrete Sealer
Best for: Owners of exterior concrete or pavers who want color enhancement without a high-gloss finish. The solvent-based acrylic sealer is described as creating a low-gloss wet look that darkens the surface. Its stated protection targets include abrasion, vehicle and foot traffic, road salts, UV rays, water absorption, snow, and ice.
Choose AR350 over AR500 if a subdued sheen is preferable to a high-gloss appearance. It is designed for unsealed surfaces and surfaces previously treated with a solvent-based acrylic sealer. Avoid choosing it if you want the concrete to retain its original dry appearance: the listed color enhancement is intended to make the surface look darker and wet. Check the existing sealer type before application.
Armor AR500 High-Gloss Concrete Sealer
Best for: Concrete and paver owners seeking a pronounced wet look and high-gloss finish. This professional-grade, solvent-based acrylic product is formulated to darken and enhance the surface. Its described protective uses include helping defend against abrasion, traffic, road salts, UV exposure, moisture, snow, and ice.
AR500 is the better choice than AR350 when gloss is a priority; both are intended for exterior concrete and pavers and offer color enhancement. The product information specifies unsealed surfaces or surfaces previously sealed with a solvent-based acrylic sealer. Its limitation is the finish: avoid it if you do not want a darkened, high-gloss appearance. Confirm the surface and prior coating match the stated use.
MasonryDefender Penetrating Concrete Sealer
Best for: Concrete driveway owners who want water repellency without a glossy coating or visible color change. This 1-gallon silane-siloxane sealer is described as penetrating concrete, repelling water, and allowing the surface to breathe. Listed concerns it helps protect against include pitting, freeze-thaw cycles, ice-melt salts, chloride ions, and efflorescence stains.
Choose this over AR350 or AR500 if preserving the concrete’s appearance matters more than creating a wet look. It is a clear, non-glossy water repellent for concrete driveways, sidewalks, and patios. It is not presented as an asphalt sealer or a color-enhancing coating. Buyers seeking a decorative gloss should compare the Armor products instead.
NIEFARG Flexible Concrete Crack Filler
Best for: Repairing common surface cracks in concrete before applying a suitable surface treatment. The listed features include a flexible formula designed to accommodate temperature changes and ground movement, plus a weather-resistant barrier against moisture, oil, UV exposure, and freeze-thaw cycles.
This product is included as a repair step, not as a full-driveway sealer. Choose it if the concrete has surface cracks that need attention before sealing. The listed limitation is that wider gaps may require multiple applications. The product information does not establish it as a solution for potholes, structural movement, or sealing an entire driveway; assess larger damage separately.
Buying Guide: How To Choose A Driveway Sealer
Is the driveway asphalt or concrete?
Identify the surface before comparing products. Black Jack Drive-Maxx 1000 is the listed asphalt filler and sealer. Armor AR350, Armor AR500, MasonryDefender, and NIEFARG are described for concrete-related uses. A product intended for concrete should not be assumed suitable for asphalt, or vice versa.
What finish do you want?
For a low-gloss wet look and color enhancement on concrete or pavers, compare AR350. For a high-gloss wet look, compare AR500. MasonryDefender is the option described as clear and non-glossy, with no change to concrete’s appearance. Decide whether appearance enhancement or a more natural look is the priority.
Do cracks need repair first?
Small cracks in asphalt are addressed by the sand-containing Black Jack formula, but larger cracks and potholes call for separate repair, according to its product information. NIEFARG is intended for common surface cracks in concrete; wider gaps may need repeated applications. Repair needs vary by material and damage, so do not treat a surface sealer as a replacement for patching.
What should you check before buying?
- Existing coating: AR350 and AR500 specify unsealed concrete or pavers, or surfaces previously treated with a solvent-based acrylic sealer.
- Desired protection: Compare the listed concerns, such as water, salts, UV exposure, traffic, and freeze-thaw conditions.
- Coverage and preparation: Product details provided here do not specify coverage or full application directions. Check the package instructions and prepare the surface as directed.
- Container size: The listed options include 5-gallon sealers and a 1-gallon penetrating sealer; choose based on project needs and the manufacturer’s coverage information.
