Oak as decking wood: solid oak decking boards for the terrace
Oak as decking wood brings the character of solid oak outdoors. Depending on the grading, the appearance of the boards can be more uniform or more lively. The visible wood grain and the play of colors of the oak look just as good on the terrace as they do indoors in the form of parquet or solid wood flooring.
Is oak suitable as decking wood?
Yes. Oak can be used as solid decking boards in outdoor areas. As with real wood decking in general, the construction should be designed in such a way that rainwater can drain off and any moisture that has penetrated can be released again.
The wood changes as it weathers. The color fades to gray, the surface develops further, and cracks can also change or form. Such changes are typical for the behavior of solid real wood boards outdoors.
Like real wood decking boards in general, oak decking boards are not classified as suitable for walking barefoot.
What should be considered when fastening oak decking boards?
Oak wood contains tannins. If these come into contact with unsuitable metals, especially those containing iron, in moist conditions, dark to black discolorations can form on the wood surface.
Therefore, A4 stainless steel screws must be used to fasten oak decking boards. This avoids contact with unsuitable iron-containing materials.
The type of screw used also depends on the substructure. In the case of aluminum profiles, the screw must be suitable for fastening to the respective profile.
You can find suitable A4 stainless steel screws for decking boards in the Gunreben product range.
Which substructure is suitable for oak decking boards?
Depending on the installation, wood or aluminum substructures are suitable for oak decking boards. It is important that the substructure, fasteners, and board cross-section are matched to one another.
For the 25 × 140 mm oak decking board offered by Gunreben, Angelim Pedra and aluminum are intended as substructures.
Water drainage is just as important. Rainwater should not collect under the boards or in the area of the substructure. Sufficient ventilation of the construction also helps to ensure that moisture can be released.
How does oak change in outdoor areas?
Exposed to sun and rain, oak wood changes its color over time and turns gray. This gray surface can be left as is.
Cracks can also change or appear due to changing wood moisture. This is something to generally expect with solid real wood decking boards and is not a peculiarity of oak.
If you wish to delay the graying process, a pigmented decking oil suitable for oak decking boards can be used. The treatment does not prevent weathering and may need to be reapplied depending on the location and the desired appearance.
