Question 1

How long does Cumaru decking last?

Accepted Answer

Cumaru (Brazilian Teak) has an expected lifespan of 50+ years when properly installed. Its extreme density and natural oils give it durability comparable to Ipe without chemical treatments.

Question 2

What is the difference between S4S and Grooved Cumaru?

Accepted Answer

S4S boards are surfaced on all four sides for traditional face-screw installation. Grooved boards have side grooves designed for hidden-fastener systems, producing a clean, fastener-free surface that is ideal for barefoot areas like pool decks.

Question 3

Does Cumaru require maintenance?

Accepted Answer

Cumaru is very low maintenance. Left untreated, it weathers into a refined silver-gray patina. To preserve its warm golden-brown tones, apply a UV-protective hardwood oil once or twice per year.

Question 4

Is Cumaru resistant to insects and rot?

Accepted Answer

Yes. Cumaru is naturally resistant to rot, fungal decay, termites, and other wood-boring insects thanks to its density and natural oils — no chemical treatments required.

Question 5

Is Cumaru a good choice for pool decks and waterfront projects?

Accepted Answer

Absolutely. Cumaru is dimensionally stable, splinter-resistant, and naturally moisture-resistant, making it ideal for pool surrounds, docks, marinas, and other wet environments.

Question 6

How is Cumaru sourced?

Accepted Answer

Our Cumaru is sourced from responsibly managed South American forests with certified sustainable practices, ensuring minimal environmental impact.
