Cumaru Deck Installation
Cumaru is a very unique decking product with unique installation methods not commonly used for other types of decking such as composites and softwoods.
We use saw blades with 16 teeth to reduce friction when cutting, and the blade will stay sharp longer. 12" saws with 32 teeth are recommended for a miter saw.
If boards are not grooved, pre-drilling is necessary to avoid wood splitting and screw breakage. Nail guns will cause the wood to split either after impact or when the wood loses moisture. Cobalt alloy drill bits are the most effective and longest lasting when drilling into Ipe.
Stainless Steel fasteners are imperative for fastening a Cumaru deck.
Pressure treated wood is use for the framing. It provides long-term protection from rot, decay and termites without the use of any EPA-listed hazardous chemicals.
