About Dasso Decking

dasso is solid and high density decking board, made from compressed bamboo fibers with a special, patented heat treatment & CeramiX treatment process, making it one of the strongest, hardest and most durable materials on the market to create the perfect space for outdoor entertainment and relaxation. A unique feature of dasso is the head tongue and groove: this can only be done with very stable materials and enables connection of an unlimited number of boards in the length. The special symmetrical shape of the sides offers the possibility to choose between either the grooved or the flat surface, and allows for quick installation with fasteners. Like any untreated tropical hardwood species, when exposed to outdoor conditions, dasso.XTR will turn grey over time creating a very natural look.

Equipment which will be used for the application are

Option1: Clip Installation

• Determine the surface side of the boards (reeded or flat surface).
• Use fasteners  or    other    suitable fasteners in the following sequence.
• Press fastener in the groove of one decking board.
• Tighten the screw in the fastener and the sub beam.
• Where the tongue and groove are connected on the sub beam preferably use 2 fasteners, 1 for every board.
• Only use the included stainless steel decking screws (4.5x30mm)

Option2: Screw down installation

• Determine the surface side of the boards (reeded or flat surface).
• Pre-drill the screw holes 20mm from the side of the board. Be sure to pre-drill with a large enough drill to avoid cracking of the decking.
• Always screw both sides (left and right) of the board.
• Use stainless steel decking screws (5x50mm).

Directly after installation

• Pre oiled: apply 1 additional coat of exterior oil directly after installation.

Follow the instructions of the oil.

finished Dasso decking is double sided, pre-oiled with exterior decking oil

• Clean the floor at least one time per year with decking cleaner. Depending on climate and use it may be necessary to perform cleaning more than once per year
• Remove the dirt water residue on the boards with clean water and let the floor dry.
• Apply 2 new layers of decking oil. When not applying new outdoor oil 1-2x per year, the floor will turn in to a grey color tone and the typical bamboo wood grain structure will become less visible.
• It is advisable to keep the decking free from dust and dirt as much as possible.
