However, neither product will withstand continuous water use or standing water, or hold up to knife cuts. We always use a cutting board just as we would on a standard kitchen counter. Basically, all horizontal wood surfaces in a kitchen must be maintained, and will easily wear with high water use.
Differences:
Butcher Block Oil is a maintenance product that should be reapplied over time. It has a lovely matte finish that soaks into the wood and is an excellent protectant for wood surfaces that come in contact with food. Simply wipe on, allow 5 minutes to penetrate and wipe off the excess. It can also be used on cutting boards, utensils, or bowls. It is one of our most popular finishes for butcher-block counters.
Arm-R-Seal is a fine furniture finish, offers several levels of sheen and is a durable finish. It has been successfully used on home bar projects with this caveat: no fine furniture finish is impervious to water. Spills must be wiped up in a timely manner.
For a more water-resistant finish, we recommend visiting a finish dealer that carries lines specifically designed for high water use such as an Epoxy or a professional two-step catalyzed finish such as General Finishes Conversion Varnish.
