Residential Deck Installation & Maintenance

Teak is a low-maintenance decking. It naturally weathers into light silvery gray tones – there’s no need to apply annual sealers. To enjoy its warm golden-brown hues, a simple application of an outdoor finish can be periodically be applied to maintain its beauty. Consult our installation guide, available at your dealer, for more outdoor finishes and hints on working with Teak.

Iron Woods Teak decking is supplied as kiln dried lumber and is for outdoor use only. Store the wood out of direct sunlight and be sure to keep it dry and off the ground. Allow the wood to acclimate and stabilize to the installation area’s humidity before installing.

We recommend carbide-tipped saw blades and high-quality drills for smooth cuts.

These spans are are designed for Teak and to allow for minimal deflection of the deck surface. For maximum spans and engineering data, you can contact us.

Allow a 3/16″ gap between 6″ wide deck boards and a 1/8″ gap between 4″ wide deck boards for drainage, airflow and expansion. Kiln dried decking may expand 1/8″ on 6″ wide boards during times of high moisture. Expect some shrinkage in width in hot or dry areas.

Adequate ventilation of the deck is essential for long-term stability and to minimize cupping. Proper air ventilation allows air to flow in from outside the deck area, under the joists and up through the gaps between the deck boards.

For screws, we recommend a high-quality, stainless steel trim head screw. Though coated or galvanized screws may also be used, they generally cause black staining and have a shorter service life. To install Iron Woods Teak, you must pre-drill a pilot hole and countersink to avoid splitting and then fasten with the stainless steel screws, which are available at Iron Woods dealers.

Seal Iron Woods Teak immediately after installation to reduce the potential for surface checking. If installing over a prolonged period or during hot weather sealing after each phase is recommended. Be sure to seal all ends immediately after cutting with Anchorseal clear wax end sealer (available from your Iron Woods dealer) in order to reduce end checking.

To maintain a golden brown color, use a transparent, penetrating oil-based sealer with UV inhibitors in a trans-oxide pigmented tint and reapply annually or as needed.

If you prefer a natural, silvery-gray appearance, use a clear oil-based sealer for the first coat and then simply let the wood weather to its natural gray color. If you want to return silver-gray wood to the original color, use a “wood brightener.” Careful power washing and/or sanding can help to remove the grayed wood.
