Curupay, also known as Patagonian Rosewood Flooring, is one my favorite species. It has incredible strength properties, including a Janka Hardness rating of 3840 pounds. That’s almost 300% harder than Red Oak.
See our Janka Hardness chart comparing all our popular hardwood flooring species.
Patagonian Rosewood is very sensitive to ultra violet rates and will darken on exposure. After installation, it is important to leave as much area as possible uncovered by rugs or carpets. The flooring will need a few months to darken.
We have recently begun adding a light red-brown stain to our Curupay flooring. We call this “Natural” and it effectively ages the product to its natural color. There will still be some darkening of the product after installation, but this new staining process will help the process and help protect the wood from extreme ultraviolet conditions which can eventually bleach out your flooring.
Modern windows are frequently coated with UV inhibitor or a thin film (typically made by 3M). This slows the natural darkening of the wood and can help to prevent bleaching.
