Ghostshield Siloxa-Tek 8500 Sealer
Ghostshield Siloxa-Tek 8500 is a water-based penetrating sealer that reduces moisture intrusion while preserving a natural look on polished concrete, brick, and pavers. It forms no film, so peeling and yellowing are unlikely, and its high actives deliver durable, long-lasting protection. The breathable formula resists wind-driven rain and deicing salts without changing the surface appearance, making it suitable for both indoor and outdoor applications.
Because it’s DOT-approved and designed for durability, it’s a strong choice for concrete facing weather exposure or high foot traffic. It resists chloride damage from road salts, helping protect surfaces in winter conditions. The product is well suited for polished concrete where maintaining a clean, natural aesthetic is important while adding robust protection.
- Breathable, non-film-forming.
- Water and salt repellent.
- Indoor and outdoor compatibility.
Armor AR350 Low Gloss Sealer
Armor AR350 Low Gloss Wet Look Sealer is a professional-grade solvent-based option for exterior concrete and pavers. It creates a protective, low-gloss finish that deepens color and enhances the surface’s natural texture. The formula is designed for unsealed surfaces or surfaces previously sealed with a solvent-based acrylic sealer, delivering a durable, non-yellowing layer that resists abrasion, road salts, UV exposure, and harsh weather.
Expect a long-lasting barrier for driveways, walkways, pool decks, and other exterior surfaces. The wet-look finish pairs well with additional coatings or sealers if a deeper protection or higher gloss is desired, making it suitable for polished concrete that sees outdoor use and seasonal exposure.
- Dramatic color enhancement; durable.
- Low-gloss, wet-look finish.
- Solvent-based; UV and weather resistant.
McKinnon Concrete Sealer, Paver Sealer

The product yields a high-gloss wet look that enhances color and durability in high-traffic areas without sacrificing surface clarity.
Its penetrating formula bonds with the surface to form a durable shield that won’t peel easily, even on busy floors. Substrate versatility—covering concrete, brick, stone, limestone, flagstone, pool decks, and more—makes it a flexible option for commercial spaces and residential projects alike where a polished finish is desired with strong protection.
- Versatile substrates: concrete, brick, stone, limestone, and more.
- Durable, peel-resistant finish.

Zep Stain Resistant Floor Sealer
Zep Stain Resistant Floor Sealer is a professional-grade step-two product in Zep’s four-step floor system. It’s designed to be applied before polishing to boost gloss, stain resistance, and polish longevity. It is not a stand-alone sealer, so it works best as part of a complete floor finishing process on unfinished vinyl, rubber, concrete, and tile floors.
Use it in conjunction with proper surface prep to maximize gloss retention and stain resistance. This product is widely used in commercial spaces where polished concrete must maintain a bright, durable surface under heavy traffic, particularly when paired with subsequent polishing steps.
- Improves gloss and stain resistance as part of a system.
- Not a stand-alone sealer; requires prep and polishing steps.
- Recommended for unfinished vinyl, rubber, concrete, and tile floors.
Buying Guide
When selecting a sealer for polished concrete, consider how the space will be used, climate, and whether you want a penetrating protection that preserves natural aesthetics or a film-forming layer that adds visible gloss and protection. For indoor spaces with high visibility, breathable penetrating sealers help maintain a natural look while offering moisture resistance. For outdoor areas or surfaces subject to heavy weather, choose sealers with robust UV resistance and salt-damage protection. Layering, such as combining a penetrating sealer with a gloss-enhancing topcoat or polish, can optimize both appearance and durability.
Scenarios And Recommendations
Indoor showrooms or residential garages that require a balanced sheen and easy maintenance may benefit from penetrating sealers like Siloxa-Tek 8500 combined with a light polish. Outdoor spaces, such as driveways or pool decks, often need color enhancement and weather resistance provided by products like AR350 or McKinnon Sealer, especially in climates with freeze-thaw cycles. In areas with high foot traffic and a preference for gloss, consider a layered approach that starts with a penetrating sealer and follows with a targeted gloss-enhancing finish.
Key Purchase Considerations
- Surface compatibility and condition: Match the sealer to polished concrete, existing coatings, and substrate if needed.
- Indoor vs outdoor use: Opt for breathable, low-VOC options for interiors; UV and water resistance for exteriors.
- Gloss level and aesthetics: Decide between natural, low-gloss, or high-gloss finishes; plan for future polishing steps if needed.
- Application method: Evaluate whether a roller, sprayer, or brush best suits your project scale and surface access.
- Cure time and maintenance: Plan downtime for curing and schedule reapplication based on wear and climate.
- Environmental impact: Prefer water-based formulas for lower VOCs when possible.
- Maintenance routine: Consider cleaning products and frequency of reapplication to maintain appearance and protection.
