190x19 Merbau Decking Select Grade KD Solid DPR

190x19 Merbau is a wide-board hardwood timber typically used for high-end decking, screening, and outdoor furniture. It is highly valued for its natural Class 1 durability (above ground), rich reddish-brown colour, and resistance to termites and rot. 

Key Specifications

• Dimensions: The boards are 190mm wide and 19mm thick.
• Grade: Most commonly available as Select Grade, which ensures a high-quality finish with minimal defects.
• Drying: Usually Kiln Dried (KD) to increase stability and reduce the likelihood of shrinkage or movement.
• Finish: Available as Dressed All Round (DAR) with a smooth finish and often features slightly pencil-rounded edges for safety and aesthetics.
• Fire Rating: Typically classified as BAL 29, making it suitable for use in many bushfire-prone areas. 

Availability and Lengths

Suppliers generally offer these boards in both random lengths and set lengths, often in 300mm or 600mm increments. 

• Standard Increments: Lengths often range from 1.8m up to 5.7m.
• Wait Times: According to Decking Wood QLD, lengths longer than 3.6m may be subject to longer lead times.
• One Joint/Finger Jointed: Some suppliers provide "One Joint" or finger-jointed boards to achieve longer, straighter spans with less deflection.

Maintenance Considerations

• Tannin Bleeding: Merbau is known for "bleeding" tannins when wet, which can stain surrounding surfaces like concrete or tiles.
• Protection: Regular cleaning, sanding, and sealing are required to maintain its deep colour.

Fasteners: Stainless steel screws or nails are strongly recommended to prevent rust stains from developing on the timber.
