Workability
Generally works well, though interlocked grain can cause tearout during planing. Contain calcium carbonate deposits which can dull cutting edges rapidly.
Finish Recommendations
Takes stains and finishes well, though large pores may require a grain filler for a smooth high-gloss finish. Teak oil or polyurethane are excellent for outdoor or indoor use respectively.
Notable Features
Can have a faint scent when being worked; known for its excellent stability and strength-to-weight ratio. Dust can be a moderate sensitizer/irritant.
