MasonryDefender Concrete Sealer
MasonryDefender is a clear penetrating sealer designed to shield concrete surfaces without altering color or sheen. The water-based formula bonds with concrete and masonry to form a breathable, water-repellent barrier. It helps protect driveways, sidewalks, and patios from moisture-related damage, including pitting and freeze-thaw stress, while resisting salts and efflorescence. Because it remains invisible, its protective layer does not change curb appeal or require surface maintenance beyond routine cleaning.
- Clear, non-glossy finish that preserves appearance
- Penetrating silane-siloxane protection
- Breathable, water-repellent performance
- Protects against ice melt, salts, and efflorescence
Rainguard Concrete Sealer
Rainguard Water Sealers provides penetrating, hydrophobic protection that creates an invisible barrier against water and contaminants. It is designed for unpainted and unsealed concrete surfaces, helping to prevent damage from freeze-thaw cycles, moisture, and staining. The sealer offers multi-purpose use for indoor and outdoor concrete surfaces while delivering a natural, no-gloss finish that preserves the original look of driveways, garage floors, pool decks, and walkways.
- Invisible barrier against water, salts, and stains
- Hydrophobic protection with breathability
- Natural, no-gloss finish
- Suitable for multiple concrete surfaces
Armor SX5000 WB Natural-Look Sealer
The Armor SX5000 WB is a professional-grade, water-based silane-siloxane sealer designed for unsealed concrete, brick, pavers, and masonry. It chemically reacts to form a durable, water-repellent barrier that dramatically reduces water absorption—often by up to 95%—without changing the look, color, or feel of the substrate. It is especially suitable for surfaces exposed to harsh weather, road salts, and chloride exposure, delivering long-lasting protection with a natural appearance.
- Professional-grade silane-siloxane formula
- Drastically reduces water absorption (up to ~95%)
- Natural look with no color change
- Breathable, weather-resistant protection
Siloxa-Tek 8500 Ready to Use
Siloxa-Tek 8500 is a ready-to-use, penetrating silane/siloxane sealer designed to reduce water and moisture intrusion on concrete, brick, masonry, and pavers. It leaves a clear, natural appearance and is DOT-approved, reflecting its suitability for exterior applications subject to deicing salts and chloride exposure. The formula is breathable and non-film forming, preventing peeling while providing long-term protection against surface degradation from freeze-thaw cycles.
- DOT-approved, breathable, non-film-forming
- Clear finish preserves natural aesthetics
- High actives concentration for durable protection
- Resists chlorides and deicing salts
DryWay Water-Repellent Sealer
DryWay is a penetrating silane-siloxane solution formulated to protect concrete, brick, block, and pavers. It penetrates deep below the surface to form a durable, non-film-forming barrier that never peels or fades like acrylic sealers. The natural finish helps maintain the driveway’s appearance, while its long-lasting protection—up to five years in a single application—supports curb appeal and minimizes maintenance in high-traffic areas.
- Penetrating, non-film forming sealant
- Long-lasting protection (up to 5 years)
- Natural finish with good traction
- Ideal for driveways, garages, patios, and pool decks
Buying Guide
Choosing the right driveway sealer involves balancing penetration depth, finish, climate, and maintenance needs. Here are key considerations to help you decide which product best fits your project.
- Penetration versus film-forming: Penetrating sealers protect from within the concrete, preserving color and texture; film-forming sealers create a surface layer that might shine or peel over time. For driveways with heavy traffic or salt exposure, deep penetration with breathable barrier is often preferred.
- Finish and appearance: Natural, non-glossy finishes preserve the concrete’s appearance, while wet-look sealers enhance color and depth. If you plan to preserve the current look, choose a clear penetrating option.
- Durability and longevity: Look for expected protection duration and the sealer’s resistance to freeze-thaw cycles, salts, and oil stains. Penetrating sealers generally require less maintenance than film-formers.
- Substrate compatibility: Confirm the sealer is suitable for your concrete type (new vs. aged, unsealed vs. previously sealed) and for other surfaces like brick, pavers, or natural stone if used in the same area.
- Climate and salt exposure: Regions with winter road salt or coastal salt spray benefit from salt-resistant barriers and breathability, which reduce surface cracking and efflorescence.
- VOC content and safety: Low-VOC and breathable formulas are better for indoor-use or occupied spaces and align with environmental considerations.
- Application conditions: Temperature, humidity, and surface preparation affect performance. Allow proper curing and clean surfaces before sealing to maximize adhesion and durability.
- Maintenance and reapplication: Some sealers require reapplication every few years; others offer longer lifespans. Plan for periodic inspections and prepare for resealing as the protective layer degrades.
- Cost and coverage: Compare cost per square foot and coverage rates (varies with porosity, surface texture, and weather conditions) to estimate project scope and budget.
Across these options, select a product calibrated for your climate, substrate, and maintenance preferences. A penetrating, breathable sealer with a natural finish generally provides durable protection without altering appearance, while products offering superior salt resistance are ideal for colder climates and coastal areas. Consider your driveway’s traffic level, whether you’ll park vehicles or host foot traffic, and how much maintenance you’re willing to perform over time.
