Heart Pine (Antique) Wood Flooring

Pinus spp.

Sample is 3/4-by-3-inch square-edge solid strip.
Top portion is finished with water-base urethane;
bottom with oil-modified polyurethane.



Color: Heartwood is yellow after during and 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.


Hardness/Janka: 1225; 5% softer than Northern red oak.
Dimensional Stability: Above average (change coefficient .00263; 29% more stable than red oak).
Durability: Natural resistance to insect infestation in heartwood; dense.



Sawing/Machining: Good machining and handtooling qualities.
Sanding: Tendency to clog paper due to high resin content; begin with coarse grade.
Nailing: Good holding quality.
Finishing: Accepts both surface and penetrating finishes. Some stains may blotch; raising grain first may help. To reduce the wood's tendency to repel finish coats, surface resins may be removed with a solvent that is compatible with the finish to be used
Comments: (Slow-growth longleaf pine, often recovered from structural timbers in pre-1900 warehouses and factories, or as sunken logs from river bottoms.
