Only one coat of this unique combination of of oil and water, that reduces timber swelling and shrinking, is required prior to a protective top coat.

As the name suggests, this is a base coat not a finishing treatment. To ensure longstanding beauty and acheive full protection of the wood, surfaces must be treated with an appropriate Osmo external wood finish.
