Our take on the Mondaria Waterproof Aluminum Plastic Composite Decking Planks, Black Coffee, 3 Pieces

A three-piece pack of Mondaria decking planks in Black Coffee, made from an aluminum core clad in plastic composite and rated for outdoor use with water protection. The aluminum core gives the boards more stiffness than hollow all-plastic composite, so they resist sagging between joists. The best new price is $152.99 at Wayfair as of November 5, 2026, and only one store lists it new, so there is no cheaper alternative to compare against.

Questions and answers

Is composite decking worth it over wood?
Composite skips annual staining and sealing, which pays off over several years. It costs more up front than pressure-treated wood and can get hot underfoot in full sun.
How much area do three planks cover?
Coverage depends on the plank width and length, which this listing does not state. Measure your run and check the board dimensions before ordering, since three boards suit small patches, not a full deck.
Can I cut these planks?
Yes, an aluminum-core plank cuts with a carbide-tipped blade or a metal-cutting saw. Seal or cap the cut ends so water cannot get between the aluminum and the composite shell.
Do the planks need a frame underneath?
Yes. They are decking boards, not freestanding panels, so they need joists at the spacing the maker specifies. The aluminum core allows wider spacing than hollow composite in most cases.
When is the price lowest?
The best new price was $152.99 at Wayfair as of November 5, 2026, from the only store listing it new. With one seller, discounts are unlikely outside seasonal decking sales in spring.
Where is the Mondaria Waterproof Aluminum Plastic Composite Decking Planks, Black Coffee, 3 Pieces cheapest?
At Wayfair, for $152.99, as of our latest check.
