On untreated new or freshly sanded raw wood, apply several coats of oil wiping away any excess. A warm room or warm oil will help the penetration. These protective oils never dry or cure and need reapplication frequently.
Every time the surface is washed the oil should be reapplied. Wipe an even coat on allow to sit overnight and wipe away any oil remaining on the surface.
A cutting board surface is never "Finished"
the oil is a continuing maintenance treatment, not a finish.
Another finish that can be used is pure Food Grade Raw Tung Oil (USE ONLY the RAW Tung)
. This oil is from the nut of the tung tree. Raw Tung Oil dries by oxidation. Several coats will be needed; apply at 24 to 48 hour intervals to allow curing. This finish may be maintained by replication of tung oil as needed or some use a Butcher Block oil such as Terra Nova NaturOil as required to maintain the surface.
Butcher Block Counter Tops
& Wood Tops that Will NOT
be used as a Cutting Surfaces
For professional spray application:
Conversion Varnish is an excellent choice for wood counter tops that will NOT be used as a cutting surface.
For on site brush application:
Butcher Block type counter tops, especially those containing a sink or stove top are best protected with a film building finish such as the Behlen Salad Bowl Finish (an FDA approved Urethane finish). Wood counter tops that will NOT be used as a cutting surface may also be finished with Salad Bowl finish.
Several coats Must be applied to seal the wood from moisture. The advantage of the “Salad Bowl” finish is an easy to clean stain resistant gloss finish that will retain the new look much longer than an oiled finish
