Mesquite

Mesquite Wood Flooring
Sample above is .75" by 2.25 " inch square-edge solid strip. Top portion is finished with water-base urethane; bottom with oil-modified polyurethane.
Appearance

Color: Light brown to dark reddish brown. 
Grain: High in character, with ingrown bark and mineral streaks. Most commonly used in flooring as end-grain block, which has small irregular cracks radiating across the grain. 
Variations Within Species and Grades: One grade; moderate color variations.

Properties

Hardness/Janka: 2345; 82% harder than red oak. 
Dimensional Stability: Excellent 9change coefficient .00129; 65% more stable than red oak). 
Durability: Dense and very strong. End-grain cut has excellent resistance to abrasion and shock.

Workability

Sawing/Machining: Very good machining qualities.
Sanding: Plainsawn can be sanded to a smooth surface; end-grain requires #16 grit sandpaper to flatten. 
Nailing: Good holding ability, but splits easily. 
Finishing: No known problems. 
Comments: End-grain block usage results in a hard, high-wear surface. Produces only small size boards.
