Why Choose Cumaru for Outdoor Flooring
A Cumaru porch floor delivers the same no-paint-ever promise as Ipe at a price that makes large porch flooring projects genuinely affordable. Brazilian Teak outdoor flooring at 3,330 Janka provides a porch surface nearly as hard as Ipe — dramatically harder than any painted pine, composite, or vinyl porch floor on the market — while costing meaningfully less per square foot. For wrap-around porches, full-width screened rooms, and multi-area covered decks, the savings add up fast.
Cumaru T&G porch floor boards display warm golden-brown to reddish-tan tones underfoot that make covered outdoor spaces feel inviting and sun-warmed. The natural color warmth of Brazilian Teak creates a floor that welcomes bare feet, complements outdoor furniture, and makes every porch feel like an extension of the home's interior. This warm tonality is one of Cumaru's greatest strengths for porch floor applications.
In a covered porch environment, Cumaru performs virtually identically to Ipe. Both are Class 1 durability, both are Class A fire rated, and both resist rot, insects, and decay naturally for decades. The modest Janka difference (3,330 vs 3,684) has negligible practical impact on a protected porch floor — you won't feel or see the difference underfoot. For porch flooring specifically, Cumaru is the smartest value in the hardwood category.
A Cumaru screened porch floor or covered deck delivers 50+ years of service without painting, staining, or chemical treatment. Compared to painted pine floors that need scraping and repainting every 2-3 years, a single Cumaru installation eliminates decades of ladder work and paint cans. The same no-paint promise that makes Ipe famous applies equally to Cumaru — just install it, and enjoy it.

Cumaru Porch Floor vs Ipe Outdoor Flooring
Ipe is slightly harder (3,684 vs 3,330 Janka) with a longer track record. In a covered porch environment, both perform virtually identically. Cumaru costs less per square foot — ideal for large porches where savings are substantial.
Learn moreCumaru Porch Floor vs Painted Pine Porch Floor
Painted pine needs full repainting every 2-3 years, peels in humidity, and lasts 5-10 years between replacements. Cumaru never needs paint, is nearly 10 times harder (3,330 vs 380 Janka), and lasts 50+ years. One installation, zero repainting.
Cumaru Porch Floor vs Composite Porch Flooring
Composite porch flooring costs similar to Cumaru but feels like plastic, retains heat, and lasts only 15-25 years. Cumaru provides real wood warmth and beauty with 2-3 times the lifespan and Class A fire safety that composites lack.
