Pros and Cons of Armor AR350

Application Guide for Best Results
Applying the AR350 is relatively simple, but proper surface preparation is crucial.
Steps:
- Clean the Surface – Remove all dirt, dust, grease, and old coatings.
- Dry Completely – Ensure the concrete is dry before sealing (at least 24–48 hours without rain).
- Apply with a Roller or Sprayer – Use a solvent-resistant sprayer or 3/8” nap roller.
- Apply Thin Coats – 1–2 thin coats are better than one thick coat.
- Let Dry – Allow at least 24–48 hours before walking and 72 hours before driving.
Optional: Add anti-slip grit during the second coat if applying on a walking surface.
Application Process
Applying the Armor AR350 is relatively straightforward. Here’s a simple breakdown:
- Surface Preparation: Clean the concrete thoroughly and ensure it’s completely dry. Avoid sealing in extremely humid or rainy weather.
- Application Method: Use a roller or a sprayer. A solvent-resistant sprayer is ideal for larger areas.
- Drying Time: It typically dries to the touch within 1–2 hours. A second coat can be applied after 24 hours if needed.
- Curing Time: Allow at least 36–48 hours for light foot traffic and up to 72 hours before driving or placing heavy objects on the surface.
Tip: Always test on a small area first to check for compatibility and desired finish.
Coverage Area
The Armor AR350 offers great coverage:
- One gallon covers approximately 175–225 sq. ft. per coat depending on the porosity of the surface.
- For best results, a two-coat application is recommended, especially for more absorbent surfaces.
Appearance and Finish
One of the standout features of the AR350 is its rich, wet-look appearance. It slightly darkens the concrete surface while highlighting the natural tones and textures. The finish is:
- Low-gloss (not too shiny, just enough to make your surface pop)
- Non-yellowing with UV stability
- Enhanced clarity that brings life to dull or weathered concrete
It’s ideal for homeowners who want to bring out the beauty of their concrete without creating a slick or overly glossy surface.
Performance Over Time
The Armor AR350 is a solvent-based, acrylic concrete sealer designed to enhance and protect both indoor and outdoor surfaces. What sets it apart is its UV-stable, non-yellowing formula that maintains clarity and shine over time. It’s especially known for its “wet look” finish that enriches the natural color of the concrete or pavers without creating a plastic-like appearance.
Many users report that the AR350 holds up 2–3 years outdoors and even longer indoors. In high-traffic areas like driveways or walkways, this durability makes a big difference. It resists:
- UV damage
- Surface wear from foot and vehicle traffic
- Water and chemical stains
- Freeze/thaw cycles in colder climates
Proper surface prep and application are key to getting the longest lifespan from this product. Some customers also reapply every 2–3 years as part of routine maintenance to keep the surface looking fresh.
Ideal Alternatives to Consider
While Armor AR350 is known for its high gloss and durability, there are a few strong competitors you might want to compare:
- Foundation Armor SX5000 – A penetrating sealer designed for natural, matte finish lovers. It offers excellent water repellency and lasts up to 10 years.
- Ghostshield Lithi-Tek 9500 – Known for deep penetration and strengthening concrete at a molecular level. Ideal for interior and exterior use.
- Black Diamond Wet Look Stone Sealer – A more budget-friendly wet-look sealer with decent protection and shine.
- Armor AR500 – Also from Foundation Armor, this alternative provides a higher gloss level and is more suitable for exposed aggregate and decorative surfaces.
Each of these sealers caters to different aesthetic preferences and surface types, so consider your surface condition, desired finish, and exposure level before choosing.
Maintenance Tips
To keep your Armor AR350-treated surface looking fresh and functional:
- Clean regularly with a pH-neutral cleaner to avoid breaking down the sealer.
- Avoid harsh chemicals or pressure washing above 1500 PSI, which can degrade the acrylic coating.
- Reapply every 2–3 years depending on surface wear and exposure to UV rays or vehicle traffic.
- Address spills quickly to prevent staining or sealer discoloration.
- For indoor applications, use mats or rugs in high-traffic areas to reduce wear.
Routine maintenance not only preserves the wet look but also extends the life of the sealer and concrete surface underneath.

Pros of Armor AR350: Why It’s a Customer Favorite
The Armor AR350 comes with a long list of advantages, especially when it comes to ease of use and long-term aesthetics. Here’s a deeper dive into the top benefits:
✅ Enhances Concrete Appearance
Its high-gloss “wet look” gives concrete a rich, darker tone, making it ideal for stamped, colored, or decorative concrete. Many users find that their dull, faded surfaces look almost new after sealing.
✅ UV & Weather Resistance
Because it’s UV-resistant, AR350 won’t yellow or degrade under sun exposure—perfect for outdoor patios, walkways, and driveways.
✅ Durable and Long-Lasting
Protects against water, deicing salts, stains, and chemical spills. It also prevents surface erosion and helps extend the life of concrete.
✅ DIY-Friendly
Application is simple. It can be rolled or sprayed, and it self-levels, which reduces streaking or uneven patches.
✅ Breathable Formula
Allows moisture to pass through the concrete, which reduces peeling or bubbling—a common issue with non-breathable sealers.
✅ Compatible with Tint
Want a tinted finish? Armor AR350 can be used with color additives to customize your look without compromising performance.
Cons of Armor AR350: What to Consider Before You Buy
Like any product, the AR350 isn’t perfect. Here are some potential downsides to keep in mind before sealing your concrete:
❌ Strong Odor During Application
As a solvent-based sealer, it emits strong VOCs (volatile organic compounds). This means good ventilation is a must—especially indoors. Wearing a mask and ventilating the area is highly recommended.
❌ Slippery When Wet
The high-gloss finish can become slick, especially in areas exposed to rain or water. However, you can mix in an anti-slip additive during application to improve traction.
❌ Multiple Coats for Porous Surfaces
Highly porous or older concrete may absorb the first coat quickly, requiring a second coat for optimal coverage and shine. This can increase cost and labor time.
❌ Longer Drying Times in Humid or Cold Climates
Although the average dry time is 24–48 hours, humidity and cooler temps can slow this process. Plan ahead if weather is a concern.
