Overview

Mahogany decking brings timeless elegance to outdoor living spaces. Prized for its rich reddish-brown color, straight grain, and excellent workability, Mahogany has been a top choice for premium decking and outdoor furniture for centuries.

Installation Tips

Pre-drilling recommended but not always required.

Use stainless steel or coated deck screws.

Allow 1/8" spacing between boards.

Apply finish within 2 weeks of installation.

Acclimate for 3-5 days before installation.

Hidden fastener systems work well with Mahogany.

Maintenance

Apply a UV-protective finish or hardwood oil every 1-2 years to maintain color and protect from weathering. Mahogany responds well to maintenance and refinishes beautifully. Clean annually with mild soap and water. For covered outdoor applications, maintenance intervals can be extended.
