Whether you're sealing a new driveway, refreshing an old patio, or waterproofing a basement foundation, concrete sealers are essential for extending the life of your surfaces. In this category within Adhesives & Sealers, you'll find 15 top-rated products from brands like Quikrete, Foundation Armor, and Ghostshield, offering everything from crack fillers to penetrating water repellents.

What Are Concrete Sealers and Why Do You Need Them?

Concrete sealers create a protective barrier that shields porous concrete from moisture intrusion, freeze-thaw damage, salt, oils, and UV rays. Without proper sealing, concrete cracks, spalls, and deteriorates prematurely, leading to costly repairs. These products come in various formulations suited for driveways, sidewalks, pool decks, garage floors, and masonry surfaces like brick and pavers.

As part of broader Hardware solutions, concrete sealers help maintain the structural integrity of your home's exterior and interior spaces, saving time and money long-term.

Types of Concrete Sealers

Understanding the main types helps you pick the right one for your project:

  • Penetrating Sealers: These soak deep into the concrete without leaving a surface film. Ideal for breathable protection against water and salts. Examples include the FoundationArmor SX5000 WB, a water-based silane/siloxane blend for natural stone and pavers, and Ghostshield's Siloxa-Tek 8500, a DOT-approved concentrate that repels water and chloride ions effectively.
  • Topical or Film-Forming Sealers: These create a visible coating for enhanced color and gloss. Acrylic-based options like Foundation Armor's AR350 deliver a low-gloss wet look, perfect for stamped concrete, while solvent-based Cryli-Tek 5505 from Ghostshield provides high-gloss shine and water repellency.
  • Waterproofers and Fillers: Multi-purpose products like Ames Block & Wall Liquid Rubber offer elastomeric protection for foundations, and Quikrete Concrete Crack Seal or DAP fillers target repairs before sealing.
  • Water-Based vs. Solvent-Based: Water-based are eco-friendly and low-odor (e.g., Thompson’s WaterSeal), while solvent-based offer deeper penetration and durability for high-traffic areas.

For specialized needs, check penetrating options from Ghostshield Concrete Sealers, known for their ultra-concentrate formulas that make gallons from a single container.

How to Choose the Right Concrete Sealer

Select based on your surface, environment, and desired finish:

  • Surface Type: Penetrating for raw concrete; topical for decorative pavers or stamped designs.
  • Climate: Salt-repellent siloxanes for snowy regions; UV-stable acrylics for sunny exposures.
  • Application: Ready-to-use for DIY (Siloxa-Tek 8500 RTU) or concentrates for pros.
  • Finish: Matte/natural look (Armor SX5000 WB) or enhanced wet sheen (AR350).
  • Prep Work: Always clean and repair cracks first with products like DAP filler.

Consider coverage rates—many cover 200-500 sq ft per gallon—and reapplication needs (1-5 years). For larger Tools & Home Improvement projects, pair sealers with cleaners and etching solutions.

Common Use Cases for Concrete Sealers

  • Driveways & Walkways: Prevent cracks from water and de-icing salts with penetrating sealers like Siloxa-Tek.
  • Patios & Pavers: Enhance color and repel stains using wet-look acrylics from Foundation Armor.
  • Basements & Foundations: Waterproof with rubberized coatings like Ames Liquid Rubber.
  • Pool Decks & Garages: Non-slip, durable formulas resist oils and chemicals.

These versatile sealers integrate seamlessly into home maintenance routines.

Frequently Asked Questions

What’s the difference between penetrating and topical concrete sealers?

Penetrating sealers absorb into the concrete for invisible protection against water and salts without altering appearance. Topical sealers form a surface film for gloss and color enhancement but may wear faster in high-traffic areas.

How do I prepare concrete before sealing?

Clean thoroughly with a pressure washer, repair cracks using fillers like Quikrete or DAP, and etch if needed for better adhesion. Ensure the surface is dry and free of contaminants.

How long does concrete sealer last?

Expect 1-3 years for topical sealers and 5-10 years for penetrating types, depending on traffic, weather, and maintenance. Reapply as sheen fades or water no longer beads.

Are water-based concrete sealers as effective as solvent-based?

Modern water-based options like Armor SX5000 WB match solvent performance with lower VOCs and easier cleanup, making them ideal for residential use.

Can I use concrete sealer on brick or pavers?

Yes, many products like Siloxa-Tek and Foundation Armor formulas are designed for masonry, brick, and natural stone, providing breathable protection.
