Blackbutt Decking 135x19mm – Standard & Better Grade (Random Mixed Lengths)

Blackbutt is a highly regarded Australian hardwood, celebrated for its clean blonde appearance, excellent durability, and bushfire resistance. Our 135x19mm decking boards, graded as Standard and Better and supplied in random mixed lengths, are a top choice for contemporary outdoor spaces, combining architectural appeal with reliable performance.

The light, warm tones of Blackbutt complement modern and coastal designs, while its strength and fire rating make it suitable for a wide range of environmental conditions — including areas with elevated bushfire risk.

Key Features:

  • ✅ Durability Class 1 (Above Ground): Excellent resistance to decay and weathering

  • ✅ BAL 29 Rated: Certified for use in bushfire-prone areas up to BAL 29

  • ✅ Termite Resistant: Naturally repels termites and borers

  • ✅ Light, Modern Appearance: Pale blonde to honey brown tones with minimal grain variation

  • ✅ Stable & Easy to Work With: Straight grain makes it ideal for machining and installation

  • ✅ Sustainably Harvested: Responsibly sourced from Australian forests

Installation Guidelines:

  • Pre-drill and screw-fix using stainless steel screws to avoid surface damage and staining

  • Maintain 4–6mm spacing between boards to allow for expansion and airflow

  • Install over Class 1 or Class 2 framing for best long-term performance

  • Ensure good ventilation and drainage under the deck to avoid moisture buildup

  • Suitable for residential decks, balconies, boardwalks, and outdoor entertaining areas

Finishing Tips:

  • Apply a UV-stable decking oil before or shortly after installation to enhance appearance and protect against weathering

  • Reapply finish every 6–12 months, depending on sun exposure and traffic

  • Regularly clean the deck using timber cleaners to remove dirt and grime

  • If left untreated, Blackbutt will naturally weather to a silvery grey patina

Product Specifications:

  • Dimensions: 135mm wide x 19mm thick

  • Grade: Standard & Better

  • Lengths: Supplied in random mixed lengths

  • Profile: Pencil round edge or smooth finish (subject to availability)
