Different types of wood display different reactions to water exposure. Wood will shrink and cracks will develop during dry seasons due to a loss of moisture and expand during hot and humid, summer-type conditions. A heavier, denser wood will do better with water than a light wood. Water also will cause breakdowns, such as rotting and molding on the wood. Once you know the type of wood you have, it's important to treat any wood you're using. Sealing it will ensure that you get the most out of your flooring, deck or furniture.
