10 Best Food Safe Wood Countertop Sealers in 2023

If you’re hoping to chop up your food directly onto the surface of a wooden countertop, cutting board, salad bowl, etc. Then you’re likely going to want to invest in a mineral oil finish or other 100% food-safe oil to keep you, and your surfaces protected.

The reason being is that the formula used for these oils meets the quality-control standards and can comfortably be used in the kitchen, ensuring that no harmful chemicals or VOCs are present. To dive into more details on this, we’ve compiled a super detailed guide in the following article.

What Makes a Wood Finish Food-Safe?

The good news is that even though only a few wood-finishing products are technically labeled as “non-toxic when fully cured”, almost all of them are considered to be food-safe nowadays. In fact, all finishes made after 1972 are considered to be ‘food-safe when cured properly. This is why there aren’t a ton of modern wood finishes that are restricted from being used on tabletops or counters in homes or even restaurants. With that being said, basically, a wood finish is deemed to be “food-safe” once it cures properly.

The important thing to remember with food-safe wood finishes is that film-forming wood finishes are toxic in liquid form. But they become non-toxic after the solvents evaporate and the finish has dried to a hard, fully-cured film on the surface of the wood. This is why most furniture manufacturers will finish tabletops and kitchen counters with lacquer and other fast-drying materials that are typically odorous and toxic.

Once the solvents are able to evaporate, and the off-gassing stage passes, the finished product is no more toxic than any other item you’d typically find in a kitchen. One of the biggest drawbacks that people face is the curing time, as the process can be somewhat lengthy, but nevertheless worth it. Curing times can vary based on the type of finish and your home’s humidity levels, but around 30 days is considered the standard for most food-safe finishes.

Do I Need A Food Safe Countertop?

Essentially, if you plan on having food on or anywhere near your kitchen counter, then you’re definitely going to want a food-safe sealer. Though, it becomes even more vital depending on the intended use. For example, if you’re planning on using your countertop as a cutting board, then you will absolutely need a food-safe sealer, such as an all-natural oil or wax.

But, if you aren’t planning on using your countertop as a cutting board, then a film wood sealer would be more than sufficient. Such as shellac or polyurethane. The reason for this is that once film sealers fully dry and cure properly (usually takes about 30 days) they are not toxic to people or food. But you won’t want to use these film sealers as a cutting board/butcher block because you can easily cut and inject pieces of the finish into your food. So, take into account what you’ll be using the wooden surface for, and choose accordingly.

What’s the Best Type of Finish for Food-Safe Sealing?

When it comes down to choosing the best type of finish for food-safe sealing, there are a few things that you’ll want to consider beforehand. You can safely use wood finishes such as polyurethane, shellac, lacquer, or varnish on wood food utensils that won’t be subject to damage.

Though, for cutting boards, and salad bowls, where using the film finish might damage these items, it’s best to go with a quality oil or wax finish that will instead penetrate through the wood’s surface. At which point, these sort of items would be considered ‘safe’ once the carrier solvents on them completely dry.

Can I Just Leave the Wood Bare?

While it is possible to leave your wooden surfaces bare, and unfinished, you’ll be running the risk of potential stains, spills, and moisture build-up. So, it is widely recommended to apply a quality finish to any piece of wood that might come into contact with any of the aforementioned risk factors.

Although, it’s not entirely uncommon to leave things like drawer boxes, the inside of cabinets, chests, backs of pieces intended to go against the wall, seat supports, and the undersides of table tops unfinished. Just take into account how much exposure the item will get, and if there’s any potential for damage within the general area.
