An examination of the mechanisms through which this finish imparts water resistance reveals the basis for its protective qualities.
-
Hydrophobic Oil Composition
Many formulations incorporate hydrophobic oils, such as tung oil or polymerized linseed oil. These oils naturally repel water due to their chemical structure. Upon application, they penetrate the wood’s porous structure and create a barrier that inhibits water absorption. This barrier reduces the rate at which moisture permeates the wood, thereby minimizing the risk of swelling, warping, and decay. For example, a deck treated will exhibit reduced water absorption compared to untreated wood, maintaining its dimensional stability during rain or high humidity.
-
Pore Sealing Action
The oils within the treatment fill the wood’s pores, reducing the available space for water to enter. This pore-filling action effectively seals the wood surface, minimizing capillary action that draws water into the wood’s internal structure. The sealing action is especially beneficial in end-grain applications, where the wood’s open cells are particularly susceptible to water absorption. Consider the end of a wooden plank treated; the sealed pores prevent water from wicking into the wood, protecting it from rot.
-
Reduced Surface Tension
The oil alters the surface tension of the wood, causing water to bead up and roll off rather than spreading and soaking in. This reduction in surface tension minimizes the contact area between the water and the wood, reducing the likelihood of water absorption. This property is evident on outdoor furniture where water droplets remain as beads on the surface, rather than being absorbed into the wood fibers.
-
Enhanced Weathering Performance
By mitigating water absorption, the finish enhances the wood’s overall weathering performance. Reduced moisture content minimizes the expansion and contraction cycles that can lead to cracking and surface checking. This, in turn, prolongs the wood’s service life and reduces the frequency of maintenance required. Wooden boat components treated with the oil, for example, will withstand the constant exposure to water and sunlight, maintaining their structural integrity and aesthetic appearance over extended periods.
These mechanisms collectively contribute to the water resistance offered. The degree of protection depends on the specific formulation, the type of wood treated, and the application method.
