Ghostshield Siloxa-Tek 8500
Best Overall / DrivewaysPros
- Does not change surface appearance
- Excellent water repellency
- Breathable, allows moisture vapor to escape
Cons
- Higher price per gallon
- Requires clean, dry concrete for application
The Ghostshield Siloxa-Tek 8500 is a professional-grade penetrating sealer that bonds chemically with the concrete substrate. Owner reviews consistently highlight its ability to make water bead up and roll off without creating a slippery or glossy surface. It is particularly effective on porous concrete driveways where a natural look is desired.
This sealer is solvent-based and requires careful application with a low-pressure sprayer. Coverage can vary based on porosity, but most users report good results with two coats. It offers strong resistance to chloride ion intrusion, making it a solid choice for areas exposed to de-icing salts.
Rust-Oleum EpoxyShield Garage Floor Coating
Best Budget / Garage FloorsPros
- Affordable and widely available
- Creates a durable, glossy finish
- Resists oil and chemical stains
Cons
- Can become slippery when wet
- Requires thorough surface preparation
Rust-Oleum's EpoxyShield is a popular two-part epoxy coating designed specifically for garage floors. It provides a thick, protective layer that withstands hot tire pickup and common garage spills. Many owners appreciate the decorative flake system that can be added for texture.
Application requires etching the concrete first to ensure adhesion. The finish is high-gloss, which can be visually appealing but may show imperfections. It is not recommended for outdoor use in direct sunlight as UV exposure can cause yellowing over time.
Armor AR350 Wet Look Acrylic Sealer
Best Wet-Look / PatiosPros
- Enhances color and depth of concrete
- Good UV resistance for outdoor use
- Easy water-based cleanup
Cons
- Less durable than epoxy for heavy traffic
- May require reapplication every 1-3 years
Armor AR350 is a water-based acrylic sealer that provides a rich, wet-look finish that enhances the natural color of stamped or stained concrete. It is popular for patios, pool decks, and walkways where aesthetics are a priority. Owner reviews praise its ease of application with a pump sprayer.
The sealer forms a film on the surface, which provides good protection against UV fading and light abrasion. It is not recommended for driveways with vehicle traffic as the film can wear down. Reapplication is straightforward, often requiring just a light cleaning and a new coat.
Foundation Armor S2000 Solvent-Based Sealer
Best for High-Traffic AreasPros
- Extremely durable and abrasion resistant
- Good chemical resistance
- Provides a rich, deep color enhancement
Cons
- Strong solvent odor during application
- Higher VOC content, requires ventilation
Foundation Armor S2000 is a solvent-based acrylic sealer known for its toughness. It is often chosen for commercial or residential high-traffic areas like driveways, walkways, and garage floors. Owner feedback notes its ability to hold up against tire marks and heavy foot traffic better than water-based alternatives.
The solvent base allows it to penetrate deeper and form a harder film. Application should be done with a respirator and good ventilation. It can be applied to both interior and exterior concrete, but the strong smell means it is best used in open spaces.
Thompson's WaterSeal Advanced Concrete Sealer
Best Multi-Surface / DecksPros
- Low odor and easy water cleanup
- Can be tinted to match surfaces
- Good value for large areas
Cons
- Less durable than solvent-based options
- May require more frequent reapplication
Thompson's WaterSeal is a well-known brand for wood sealers, but their concrete formula is a solid water-based option for patios and walkways. It is designed to repel water and resist mildew growth. Owner reviews often mention its ease of use and low odor, making it suitable for DIY projects.
The sealer provides a satin finish that does not drastically change the concrete's appearance. It is not recommended for horizontal surfaces with heavy vehicle traffic. For light-duty concrete sealing, it offers a convenient and affordable solution.
What to Check Before Buying a Concrete Sealer
Choosing the right sealer depends on the surface location and desired finish. For driveways and garage floors, durability and chemical resistance are key. For patios and walkways, UV resistance and aesthetics may be more important. Always check the manufacturer's recommended coverage rate and surface preparation steps.
Consider the sealer type: penetrating sealers (like Ghostshield) work below the surface and are best for exterior concrete that needs to breathe. Film-forming sealers (like epoxy or acrylic) sit on top and offer better abrasion resistance but can peel if applied incorrectly.
Mistakes to Avoid When Sealing Concrete
A common mistake is applying sealer to concrete that is not fully cured. New concrete should cure for at least 28 days before sealing. Another error is skipping the cleaning and etching step, which can cause the sealer to peel or bubble. Always test a small area first to ensure compatibility and desired appearance.
Applying too thick a coat can lead to a cloudy or sticky finish. Follow the manufacturer's recommended spread rate. Finally, avoid sealing concrete in direct sunlight or when rain is forecast within 24 hours, as moisture can ruin the application.
FAQs
How long does concrete sealer take to dry?
Most water-based sealers are dry to the touch within 1-2 hours, but full cure can take 24-48 hours. Solvent-based sealers may take longer to dry but cure faster.
Can I apply concrete sealer over old sealer?
Yes, if the old sealer is still intact and clean. If it is peeling or flaking, it must be removed before applying a new coat.
What is the best sealer for a driveway?
For driveways, a penetrating silane/siloxane sealer like Ghostshield Siloxa-Tek 8500 is often best as it does not peel and protects against water and salt.
How often should I reseal concrete?
Penetrating sealers can last 3-5 years, while film-forming sealers like acrylics may need reapplication every 1-3 years depending on traffic.
Is epoxy better than acrylic for concrete?
Epoxy is more durable and chemical resistant, making it better for garage floors. Acrylic is easier to apply and better for outdoor patios where UV resistance is needed.
Can I use a concrete sealer on brick?
Some sealers are labeled for masonry and brick. Check the product label to ensure it is suitable for porous surfaces like brick.
Do I need to etch concrete before sealing?
For film-forming sealers like epoxy, etching is essential for adhesion. Penetrating sealers may only require a clean, oil-free surface.
What does VOC mean for concrete sealer?
VOC stands for Volatile Organic Compounds. Low-VOC sealers have less odor and are better for indoor use, while high-VOC sealers often provide better durability.
Can I walk on sealed concrete after 24 hours?
Light foot traffic is usually fine after 24 hours, but avoid heavy traffic or parking vehicles for at least 48-72 hours to allow full cure.
Will concrete sealer make the surface slippery?
Glossy film-forming sealers can be slippery when wet. Penetrating sealers and matte finishes offer better slip resistance.
Our verdict
For most homeowners, the Ghostshield Siloxa-Tek 8500 is the best overall concrete sealer due to its durable, breathable protection and natural finish. If you need a budget-friendly option for a garage floor, the Rust-Oleum EpoxyShield provides excellent value and a glossy, stain-resistant surface.
