How often do wood kitchen countertops need to be resealed?

How often wood kitchen countertops need to be resealed depends greatly on what type of sealer you use and how often you use the countertops. With a wax sealer, you will potentially only need to reseal the countertop once every few months. If you use a sealer such as mineral oil or linseed oil, then you will potentially need to reseal it much more frequently. For example, many homeowners will reapply this type of sealer to the countertop once every week or once every two to three weeks. If you use your countertop frequently, you will need to apply it more often.
