How to Seal a Butcher Block Surface

Butcher block requires careful cleaning and seasoning to prevent bacteria growth, water saturation and penetration by food odors. After seasoning, butcher block should be sealed to prevent discoloration and staining. The method of sealing depends on the use of the butcher block. Wood countertops that are used for cutting, chopping and slicing should be sealed with beeswax to create a surface that resists chipping and gouging. Acrylic varnish or polyurethane seals butcher block with a glossy, fine furniture-like finish not intended as a cutting surface. Varnish seal provides an ideal surface for rolling pastry.
