Please refer to our Installation Guide for detailed information about installing your Monarch™ Green Tree™ decking.

Prior To Installation Check List:

  • Every Green Tree deck board is unique in colour and shading - Take the time prior to the installation of your deck boards to arrange the boards in the manner that is pleasing to your eye.

  • Joist Spacing - A maximum of 400mm between joists for standard parallel or perpendicular decks and a maximum of 300 mm for diagonal or any sort of angle installation is advised.

  • Deck boards must be gapped on all four sides for expansion and contraction - During installation at temperatures BELOW 16° C gap a minimum of 6.5mm, ABOVE 16° C a gap of 3.5mm.

  • Fasteners - Stainless steel deck screws, composite deck screws and commercially available hidden fasteners are suggested. Pre-drilling and countersinking maybe required.

  • Nailing, gun nailing and pneumatic nail guns are not recommended.

  • Pre-drilling / Over-tightening - Pre-drilling is mandatory within 25mm end or edge of the deck board, as is driving screws only to a slightly snug condition. Failure to do either could result in the immediate or eventual cracking of the deck board.

  • Joist Attachment - Two screws should be installed at each joist.
