Maple
(Sugar/Hard) Species Information
Top portion is finished with water-base urethane; bottom with
oil-modified polyurethane.
Appearance
Color: Heartwood is creamy white to light reddish brown; sapwood
is pale to creamy white.
Grain: Closed, subdued grain, with medium figuring and uniform
texture. Occasionally shows quilted, fiddleback, curly or bird’s-eye
figuring. Figured boards often culled during grading and sold
at a premium.
Variations within species and grades: Black maple (B. nigrum)
is also hard; other species are classified as soft.
Properties
Hardness (Janka): 1450; 12% harder than Northern red oak.
Dimensional Stability: Average (change coefficient .00353; 4%
more stable than red oak).
Durability: Dense, strong, tough, stiff; excellent shock resistance — often
used in bowling alleys and athletic facilities. Markedly resistant
to abrasive wear. Workability
Sawing/Machining: Density makes machining difficult.
Sanding: Sands satisfactorily.
Nailing: Fair resistance to splitting; good holding ability.
Finishing: Takes neutral finish well; does not stain uniformly.
Comments: Light color lends itself to contemporary light floors.
Extra care must be taken during sanding and finishing, as sanding
marks and finish lines are more obvious due to maple’s
density and light color.
