Our Red Batu or Balau, commonly referred to as “Mahogany”, hardwood decking is sourced only from countries that are leaders in ecological, sustainable forestry practices. This 100% natural, uniquely beautiful, low-maintenance decking comes with a 25 Year Limited Warranty.
Extremely strong and durable hardwood decking!
Used for over 50 years extensively in the USA and abroad in the most demanding applications such as wharves, boardwalks, fishing boat decks and mineshaft timbers, it is resistant to termites and fungus.
Decking that is easy to maintain!
Penetrating finishes are best at protecting your mahogany deck and minimize
maintenance. We recommend using a finish, such as Penofin, with U.V. inhibitors to reduce fading from sunlight and mildew retardants to minimize black mildew that may form, especially in wet or damp areas. However, if you wish to let it weather to a beautiful grey, no maintenance other than light pressure washing is ever needed.
All this at a comparable price to similar clear grade softwoods and composite / plastics! 5/4×6″ decking in stock and ready to deliver!
Storage and Handling
- Keep your decking clean, dry and out of direct sunlight before installation and finishing
Finishing
- For optimum results, seal decking with a high quality penetrating sealer, such as Penofin Hardwood Formula, on all four sides prior to installation if possible
- Due to the extremely dense properties of this wood, a second field coat is recommended after “seasoning”
- Use care when applying any finish to wipe away any excess. Do not allow to pool or drip. For more tips on application, please visit the Penofin website HERE
- Should you wish to allow your decking to weather to a beautiful silver patina, no finish is necessary
- No need to wax ends
Ventilation and Air Flow
- Check and follow all local building codes!
- Allow adequate ventilation for proper airflow to reduce cupping and checking potential
- For maximum long term stability, install your deck with a minimum ground clearance of 18″ with at least two sides of the deck open
- In all cases, it is absolutely necessary to have at least 50% unrestricted air flow
- Create a slope for drainage so there is no chance of standing water
- If a minimum ground clearance of 18″ is not available, it is recommended to use 5/4×4″ decking
Spacing
- Our mahogany decking is kiln dried. Unlike air-dried boards, shrinkage is very limited. However, excessive moisture may cause the boards to expand slightly
- Install 6″ decking (5-1/2″ net) with a minimum gap of 1/4″ between boards. 4″ decking (3-1/2″ net) should have a minimum of 3/16″ between each board
- In more demanding applications, such as boat docks, decks built closer to the ground and decks with less airflow, a minimum of 5/16″ for 6″ decking and a minimum of 1/4″ for 4″decking is required
- This decking does not shrink or expand end to end, so neatly trim ends and butt together
Fastening
- Pre-drill pilot holes and countersink screws. We recommend using stainless steel fasteners and have countersinking tools in stock available to help
- Face screwing or edge screwing are the most effective methods of installation
- Color matched Headcoat Stainless Steel Screws are available and provide beautiful results time and time again
- Hidden clip fasteners and nails are not recommended and may void warranty
Maximum Allowable Decking Spans
- 1×4 and 1×6 ~ 16″ on center
- 5/4×4 and 5/4×6 ~ 24″ on center
Safety
- Though we have had no reports of irritation of any kind with this hardwood, we still recommend wearing protective eyewear, dust masks and gloves during installation
