Yes. Our wood countertops are sealed to protect them from water damage that may occur from having a sink. We do not recommend using a sealer like mineral oil because it doesn’t offer the protection that a tung-oil or our marine varnish does.

A tung-oil like Waterlox’s Original Wood Sealer is easy for a home owner to apply and offers very good protection even for countertops with sinks. The down side is that it will need re-applied once or twice a year to maintain its protective characteristics. The schedule for re-sealing is really based on how often you use the countertops. Are they used daily in your main resistance with your main sink or are they used rarely in a second home or second kitchen or bar area.

A marine varnish is an extremely hard, durable top coat finish that completely seals the wood protecting it from water damage. It’s a care free finish never needing re-applied and requires no ongoing maintenance. We really think this is a perfect all around wood countertop finish with its very good scratch resistance, little to no maintenance and ease of repair.
