The type of concrete sealer you choose depends on where the concrete is located and what look you wish to achieve.

When you invest money in a concrete surface, you want it to last. A sealer is applied to the surface to protect it from damage and staining. The sealant will block the pores in the concrete and reduce the absorption of water and salts, extending the life of the concrete. There are different types of sealer available, and it’s important to choose the right one. Tolley Concrete has some tips for picking the right sealer for your concrete surface.

Choosing the Right Sealer

There are two basic types of concrete sealer – film-forming (or topical) and penetrating. Each type has its own uses and characteristics.  

  • Film-forming sealers create a protective film over the concrete. They are often used on interior or decorative concrete floors. Many will enhance the colors in stamped concrete or acid stained floors.
    • Acrylic based sealers leave a visible film that coats the concrete surface and are available in water based and solvent based versions. They are easy to use and economical.
    • Urethane sealers are very durable and scratch and chemical resistant. They are more expensive than acrylics and require more prep work. 
    • Epoxy sealers are also quite durable and long lasting. Epoxy adheres better to the concrete surface than urethane or acrylic sealers.
  • Penetrating sealers are made of silane and siloxane and soak into the pores to bond with the concrete to protect against moisture and deicing chemicals. These sealers are practically invisible, so preserve the “as is” look of the concrete. Most penetrating sealers must be used on concrete that has cured for at least 28 days.
