Antique Heart Pine(Domestic)
- Pinus spp.
Wood Floor Appearance
Color: Heartwood is yellow after cutting & turns deep pinkish tan to warm reddish brown within weeks due to high resin content. Sapwood remains yellow, with occasional blue-black sap stain.
Grain: Dense, with high figuring. Plainsawn is swirled; rift- or quartersawn is primarily pinstriped. Curly or burl grain is rare.
Variations Within Species And Grades: Moderate color variation.
Properties
Hardness/Janka:
Janka:1225; (5% softer than Northern red oak).
Dimensional Stability: Values can vary greatly due to the variety of species and ages used.
Durability:
Workability
Sawing/Machining: Good machining and hand-tooling qualities.
Sanding: Tendency to clog paper due to high resin content; Abrasives will need to be changed frequently during sanding. Beginning with a coarse grade is recommended.
Nailing: No known problems.
Finishing: May be difficult to stain. To reduce the wood's tendency to repel finish coats, surface resins may be removed with a 100% pure (not recycled) solvent that is compatibel with the finish to be used. Do not use water.
Comments:
Origin: North America. Often recovered from structural timers in pre-1900 warehouses & factories, or as sunken logs from river bottoms.

South Yellow Pine(Domestic)
- Pinus spp.
Wood Floor Appearance
Color: Heartwood varies from light yellow/orange to reddish brown or yellowish brown; sapwood is light tan to yellowish white.
Grain: Closed, with high figuring; patterns range from clear to knotty.
Variations Within Species And Grades: Longleaf pine (P. palustris), shortleaf pine (P. echinata), loblolly pine (P. taedo), slash pine (P. elliottii). All have many of the same characteristics as Douglas fir.
Properties
Hardness/Janka: Loblolly and shortleaf 690, 47% softer than Northern red oak; longleaf 870, 33% softer than Northern red oak.
Dimensional Stability: Above average (change coefficient .00265; 28% more stable than red oak).
Durability: Soft, fairly durable, although not as resistant to scuffs, dents and abrasions as the hardwoods. Often used for flooring, but may not be suitable for all applications due to its softness.
Workability
Sawing/Machining: Good machinging qualities.
Sanding: Resin in wood tends to clog abrasives; frequent sandpaper changes are required.
Nailing: Good holding ability and resistance to splitting.
Finishing: A durable finish can help minimize wear.
