Hardwood Floors June/July 2018

HARDNESS (JANKA): 950 DIMENSIONAL STABILITY: Above average – Black (American) cherry has a dimensional stability factor of 3.7 percent (radial) and 7.1 percent (tangential), meaning this species may shrink/ swell up to 7.1 percent of its given width, depending on how it’s cut, when going from green (30 percent MC) to oven-dried (0 percent MC). DIMENSIONAL CHANGE COEFFICIENT: Black (American) cherry = .00126 (radial), .00248 (tangential) SPECIFIC GRAVITY: .50

NAILING: No known issues. SANDING:

A softer species that sands very well. It can be difficult to sand because of the density, which can make sander marks more visible than on some woods. When staining or using natural oils, it is normally required to bring the sanding sequence to a higher grit to minimize visible scratches. When sanding cherry that has been installed along with harder, denser species, it is important to sand on a diagonal and finish with a multi-head sander or hard plate to minimize dish out. Cherry stains well, but can sometimes appear blotchy, which adds to the beauty of this species, but must be addressed with the end-user during the initial finish option discussions.
