Grades & Properties of Wood Flooring —
Redland Rose (Angico)
Other Common Names and Related Species:
Kurupayra is distributed through South America, including Argentina, Paraguay, and parts of Brazil.
Janka Hardness: 3840
Redland Rose is similar to Brazilian Walnut in hardness, near the top of the scale.
Grades of Redland Rose Flooring:
Clear grade Angico flooring is color-sorted for a rich pink color. Select Angico flooring is occasionally available, but the Clear grade is most prevalent and popular.
Redland Rose Flooring Dimension Specifications:
All Redland Rose flooring is milled in South America because it is more cost-effective to ship finished material than raw lumber. Lengths of the Kurupayra flooring bundles are 7 feet so they can easily fit into 8-foot-wide steel shipping containers. All pre-milled products are tongue-&-groove and end-matched (tongue-&-grooved on the ends of the boards). Moisture content ranges from 6% to 8% for quick acclimation. The average length of the flooring pieces is usually about 3 feet and ranges from 1 to 7 feet. Almost all imported flooring that is found is in 7-foot bundles, with widths available from 2¼″ to 5″. Typically, if a long or wide plank floor is desired, raw lumber must be obtained and the flooring must be milled here in the United States. Typically, the lengths can develop up to 12 feet. However, the cost can be double that of the pre-milled stock because of waste and labor costs in the United States. Also, raw lumber is relatively expensive because it is taxed more heavily than finished products to support local economies in South America. Kurupayra lumber is virtually impossible to find in the U.S., limiting the flooring lengths to the standards of pre-milled products.
Redland Rose is available prefinished and unfinished solid for nail-down applications on a wood subfloor. Kurupayra is fairly scarce in comparison with many Brazilian species such as Brazilian Cherry. There is a moderate amount of Redland Rose in South America, and it is not endangered. However, less logging, stricter regulations, and a slower American economy have slightly limited commodities and caused slightly higher prices of this product in this country.
Finished Floor Appearance:
A Clear grade floor will have an even pinkish red appearance. Oil-based finishes allow Redland Rose to age to a deep brown color, unless lacquer or de-waxed shellac is first applied to help preserve the pink color of the wood. Water-based finishes will preserve the natural color longer.
Flooring Durability and Stability:
Kurupayra flooring is durable and resists denting and traffic wear well. It is much harder than North American species because of its density and is relatively stable. Kurupayra flooring is very heavy, weighing about 3 pounds per square foot.
Workability of Redland Rose Flooring:
Although extremely hard and tough, Angico works with limited difficulty with both hand and power tools. When installing Angico flooring, it is best to use a manual nailer, but staples and pneumatic nailers can be used. It holds screws well, and it glues, stains, and polishes to a very attractive finish. It can be somewhat difficult to sand with flooring equipment because of its hardness. Oil-based finishes allow Redland Rose to age to a deeper red color. Lacquer or de-waxed shellac can be first applied to help preserve the distinctive red color of the wood and will help with drying time. Water-based finishes will preserve the natural color longer. Professional sanding and finishing is recommended. This wood is very resistant to decay and insects; these resistant properties may contribute to a possible allergic response to the dust. To avoid a possible allergic reaction to the material, wear a dust mask and long-sleeve shirt when working with Kurupayra.
Principal Uses of Redland Rose Flooring:
Angico flooring is used in medium- and high-end residential and commercial applications for a dramatically elegant floor. It is works well in traditional and contemporary spaces.
