Armor AR350 Low Gloss Wet Look Sealer
Best for exterior concrete and pavers requiring a subtle wet look with enhanced color. It darkens surfaces using high-quality resins and provides long-lasting protection against abrasion, salt, UV, and moisture. Suitable for unsealed surfaces or those previously sealed with solvent-based acrylic sealers. Caution: solvent-based formulas can emit strong odors during application and require proper ventilation and PPE.
Armor AR500 High Gloss Wet Look Sealer
Best for unsealed concrete and pavers that demand a dramatic, high-gloss wet look with color enhancement. This solvent-based sealer provides durable, long-lasting protection against traffic and the elements. Limitation: higher VOC level means stricter handling and ventilation requirements; may require odor control measures during application.
Armor WL550 Deep Penetrating Matte Sealer
Choose this if you want subtle color enhancement without a surface gloss and prefer a water-repellent barrier that penetrates below the surface. It reduces water absorption, helping prevent cracking and staining. Caution: not ideal if you need a strong surface sheen or color depth.
McKinnon Concrete and Paver Sealer
Best for contractors needing a versatile semi-gloss wet look for concrete, pavers, brick, and natural stone. It provides outdoor durability and indoor suitability, with UV resistance to hold up under sun exposure. Limitation: performance depends on substrate porosity; very smooth surfaces may show less depth of color.
OAIEGSD 1 Gallon Concrete Sealer
Best for outdoor areas needing water resistance with a penetrating, invisible barrier. This water-based silane/siloxane sealer resists water, reduces absorption, and helps extend surface lifespan. Limitation: might require reapplication sooner on very porous or high-traffic surfaces compared to solvent-based products.
Buying Guide: Key Considerations for Commercial-Grade Concrete Sealers
Finish and purpose matter. Decide between penetrating sealers that minimize gloss and emphasize substrate color versus surface sealers that create a visible wet look. If color enhancement is desired, solvent-based sealers typically deliver deeper tones but require airflow and solvent handling measures. For food-contact areas or indoor concrete countertops, prioritize water-based, low-VOC options with food-safe certifications where relevant. Consider UV exposure, traffic level, and climate when selecting a product.
What is the difference between wet look and penetrating sealers?
Wet look sealers coat the surface to create a glossy or shiny finish that darkens the color. Penetrating sealers soak into the material, forming a protective barrier beneath the surface with minimal surface gloss.
Should I choose solvent-based or water-based sealer?
Solvent-based sealers generally offer richer color and longer-lasting protection outdoors but emit stronger odors and require ventilation. Water-based sealers have lower odor, lower VOCs, and are easier to apply indoors, though color depth may be less pronounced and longevity can vary with exposure.
How do I assess surface porosity and intended traffic?
More porous surfaces absorb more sealer and may require multiple coats. High-traffic areas benefit from more durable formulations with longer cure times and proper conditioning between coats.
What about cure and seal formulations?
Some products double as cure and seal for new concrete, aiding proper curing while sealing. Check ASTM standards mentioned by manufacturers to ensure compatibility with your project timeline.
What safety considerations are important?
Always follow manufacturer directions. Use PPE, ensure adequate ventilation for solvent-based products, and avoid applying in extreme temperatures or high humidity for best results.
Frequently asked questions
- What is the best sealer for outdoor concrete with heavy foot traffic? A high-durability, solvent-based wet-look sealer (like AR500) is often preferred for added color and protection, but consider ventilation and VOC limits.
- Can I apply sealer over existing epoxy or acrylic coatings? Typically not; most sealers require a properly prepared substrate. Follow specific product instructions for compatibility.
- Do penetrating sealers require a topcoat? Not usually, but some projects may benefit from a second coat for extra protection in harsh climates.
- Is a matte finish suitable for commercial areas? Yes, penetrating matte sealers like WL550 provide water resistance with minimal gloss, suitable for a natural look.
