Concrete sealers are protective coatings applied to concrete surfaces to enhance durability, appearance, and resistance to various elements. They act as a barrier, safeguarding concrete against water, chemicals, stains, and wear.


Types of Concrete Sealers

  • How They Work: Film-forming sealers create a protective layer on the concrete surface. They sit atop the concrete, forming a film that shields against moisture and contaminants.
  • Appearance: These sealers can enhance color, provide gloss, and highlight the concrete’s texture.
  • Applications: Ideal for decorative concrete, stamped concrete, and surfaces where aesthetics matter.
  • Pros:
    • Visual Enhancement: Film-forming sealers bring out the concrete’s natural beauty.
    • Protection: They guard against stains, UV rays, and abrasion.
    • Gloss Options: Choose from matte to high-gloss finishes.
  • Cons:
    • Peeling Risk: Improper application or environmental factors can lead to peeling.
    • Breathability: They reduce concrete’s breathability, potentially trapping moisture.
  • How They Work: Penetrating sealers soak into the concrete pores, chemically reacting to create a protective barrier within the material.
  • Appearance: Generally provide a natural finish with little to no gloss.
  • Applications: Best for high-porosity surfaces, such as driveways, garage floors, and pavers.
  • Pros:
    • Breathable: Air and moisture can pass through, preventing mold and mildew.
    • Chemical Resistance: Protects against water, oil, and contaminants.
    • No Peeling: No risk of film peeling since it doesn’t sit on the surface.
  • Cons:
    • Limited Aesthetics: Penetrating sealers don’t enhance color or provide gloss.
    • Surface Tread: They don’t alter the surface’s grip or tread.

Choosing the Right Sealer

  • Film-Forming Sealers: Opt for these when aesthetics matter, especially for decorative concrete.
  • Penetrating Sealers: Use them for high-porosity surfaces, where breathability and chemical resistance are crucial.

In summary, concrete sealers play a vital role in preserving and enhancing concrete surfaces. Whether you want a glossy finish or natural protection, choose wisely based on your specific needs!
