Armor AR350 Low Gloss Wet Look Concrete Sealer
- Professional-grade solvent-based sealer for exterior concrete and pavers.
- Designed to darken surfaces with a dramatic wet-look color enhancement.
- Long-lasting, non-yellowing low-gloss finish; protects against abrasion, salts, UV, water, snow, and ice.
Best for: Property owners seeking a noticeable, glossy-wet appearance with strong protective performance on unsealed or previously sealed solvent-based surfaces.
Limitations: Solvent-based formula may require ventilation and solvent cleanup; not ideal for indoor use or high VOC sensitivity areas.
CS-9500 Ready to Use Silane/Siloxane Sealer
- Water-based silane/siloxane penetrating sealer with low VOC.
- Repels water and deicing salts; enhances resistance to cracking and spalling.
- Natural finish preserves original appearance without changing color or texture.
Best for: Surfaces where breathability and color preservation are priorities, with strong water repellency and salt resistance.
Limitations: As a penetrating sealer, it does not add a surface film or gloss; no color enhancement.
Armor SX5000 WB Natural-Look Sealer
- Water-based silane/siloxane sealer for concrete, brick, pavers, and natural stone.
- Reduces water absorption by up to 95%; preserves natural look and texture.
- Penetrating formula; does not alter color or surface feel.
Best for: Surfaces where maximum water resistance is desired without changing aesthetics.
Limitations: No glossy finish; relies on penetration for protection, which may be slower to cure in damp conditions.
Siloxa-Tek 8500 Ready to Use
- Water-based silane/siloxane sealer with six times higher actives for deep penetration.
- 100% breathable, non-film forming; DOT approved; resists chloride and deicing salt damage.
- Leaves original appearance; minimizes cracking and spalling with long-lasting protection.
Best for: Long-term protection on concrete, brick, stone, and pavers where breathability and subtle appearance are important.
Limitations: May require proper surface preparation to ensure optimal penetration in very dusty or contaminated substrates.
Eco Advance Siloxane Odorless Spray-On
- Ready-to-use spray-on waterproofer for concrete, brick, stone, EIFS, and pavers.
- Odorless application; protects against water damage, oils, de-icing salts, and pool/spa chemicals.
- Suitable for indoor-outdoor use where odor sensitivity is a concern.
Best for: Quick, odor-conscious jobs or large outdoor areas where ease of application matters.
Limitations: Spray-on products may require even application during windless conditions to avoid streaking.
Buying Guide
What should I consider before sealing? Determine whether you need a penetrating (silane/siloxane) sealant or a surface-applied (film-forming) sealer. Penetrating sealers protect without changing appearance, while film-forming sealers can enhance color or gloss.
Water-based or solvent-based? Water-based sealers are generally safer, low odor, and easier to clean up; solvent-based sealers typically offer deeper penetration and richer color but require ventilation and careful handling.
Finish and appearance? Decide if you want a natural look, a subtle satin finish, or a dramatic wet look. Some products explicitly preserve natural appearance, while others darken or enrich color.
Surface compatibility? Verify that the sealer is suitable for your substrate (concrete, brick, pavers, stone) and whether relief textures or coatings are present that might affect penetration.
Durability and maintenance? Consider UV exposure, traffic level, de-icing salt exposure, and climate. Penetrating sealers tend to require less frequent maintenance but may need re-application after years of heavy use.
Application and safety? Review VOC content, ventilation needs, and whether application is feasible indoors or in heat-sensitive environments.
Frequently Asked Questions
- Do I need to seal concrete pavers? Sealing helps reduce water absorption, inhibits pitting from freeze-thaw cycles, and can minimize staining. Choose a penetrating sealer for a natural look or a film-forming sealer for color enhancement.
- Will sealing make my surface slippery? Some sealers, especially those with a wet-look finish, can be mildly slick when wet. Natural-look or penetrating sealers often offer better slip resistance.
- How long does sealing last? Durability depends on product type, traffic, climate, and substrate. Penetrating sealers typically last several years; film-forming sealers may wear faster in high-traffic areas.
- Can I apply sealer over existing coatings? Many sealers are designed for unsealed or previously sealed surfaces, but compatibility varies. Always check manufacturer guidance for the specific substrate.
- Is ventilation required for sealed applications? Yes for solvent-based products. Follow product safety data sheet guidelines and local regulations.
- Should I hire a professional or DIY? DIY is common for small to medium jobs; professionals are advisable for large areas, complex substrates, or high-performance requirements.
