Is There an “Ideal Sealer” for Concrete Countertops?

Let me introduce you to a concrete myth: Concrete countertops are stain prone and high maintenance. While in the past this may have been have been true, sealers have come a long way from the simple wax and acrylic sealers once used. With the right sealer you can create a countertop that fulfills many of the essential functions one wants in a kitchen: stain-resistant, heat-resistant, scratch-resistant, food safe, easy to clean, easy to maintain and perfectly smooth.

Floor Sealers and Countertop Sealers Are Not the Same

With the increased demand for concrete products, both in flooring and countertops, manufacturers are starting to recognize the demand and create more concrete sealer products. A problem arises however when manufacturers mistakenly recommend a sealer designed for concrete flooring for countertop use. Although both flooring and countertops can be made from concrete, the performance requirements are vastly different. Floor sealers are optimized for walking on, not necessarily cooking on.

The Ideal Sealer for Concrete Countertops

Bare concrete is porous and vulnerable to staining and chemical attack. Liquids will tend to soak into the surface, carrying stains into the concrete itself. Acidic substances like vinegar and lemon juice will dissolve the cement paste, etching the surface. For concrete to be a practical countertop material, it must be sealed to protect it from stains and etching.

The Ideal Sealer for concrete countertops must satisfy the basic criteria that are important both to consumers and those making the countertops.

Criteria that are important to clients (end users of the countertop):

  • Enhance the appearance of the concrete without degrading the look or feel
  • Non-porous
  • Completely resist stains from food, oil and other common household substances
  • Resist any etching from acidic substances like lemon juice and vinegar
  • Resist heat from hot pots and pans take directly from the oven or stove top at a wide range of temperatures
  • Resist UV degradation and yellowing from sunlight
  • Scratch-proof
  • Food safe (non-toxic)
  • Easily cleaned using common household cleaning products
  • Provide long term protection without the need for frequent maintenance or reapplication
  • Not peel, flake, chip or bubble
  • Easy to repair

Criteria that are important to the concrete countertop maker:

  • Inexpensive
  • Quick and easy to apply
  • Strong client appeal

Unfortunately the Ideal Sealer does not exist. However, one comes close: Omega Concrete Countertop Sealer. I developed this sealer in 2017 after many, many years of frustration and compromises with other commercially available sealers.

Omega is much faster and easier to apply than the recently popular professional-grade high-performance sealers, but it still requires practice and attention to the instructions. It is also fairly expensive, given the advanced chemistry. That’s why I say it is not the Ideal Sealer. But it is the best concrete countertop sealer on the market. Click here to learn more.
