American sycamore

Overview

American sycamore is a pale, maple-like hardwood that is best known when quartersawn, where wide rays give a bold freckled "lacewood" fleck. Plain-sawn boards are quiet and fairly plain. It is an inexpensive way to get a distinctive figure, and it is not the same as "European sycamore", which Wood Database says is actually a maple.

Pros

• Quartersawn boards show very distinct ray fleck, so a common wood gives a lively, decorative surface.
• Fine, even texture similar to maple, and generally easy to work with hand and machine tools.
• Turns, glues and finishes well.
• Moderately priced, though quartersawn stock can cost more.

Cons

• Non-durable to perishable and susceptible to insect attack; indoor use only.
• Interlocked grain can be troublesome when surfacing and machining.
• Soft for a furniture wood (770 lbf), so it dents; Wood Database says it responds poorly to steam bending.
• Wide, light sapwood with darker heartwood streaks makes colour uneven from board to board.

Variants and subspecies

• Plain-sawn: pale, plain, similar to soft maple in appearance.
• Quartersawn (lacewood): ray fleck over the whole face, the main reason people choose sycamore.
• Sapwood vs heartwood: the sapwood is white to light tan; darker reddish-brown heartwood streaks appear in most boards, and some boards are entirely heartwood.
• European sycamore is Acer pseudoplatanus, a maple, and London plane (Platanus x hybrida) is a related hybrid; neither is the same wood.
• For similar pale, even woods see Soft maple.

Working and finishing

Wood Database says sycamore generally works easily, but interlocked grain can tear out when planing or machining; use sharp knives, light cuts and a scraper. It turns, glues and finishes well. Quartersawn surfaces can be fuzzy; sand with care. Do not plan on steam bending it.

Staining and finishing colour

Wood Database reports sycamore finishes well. Because the texture is fine and even like maple, pigment stains can blotch, so test on scrap and consider a conditioner or dye. A clear finish shows the ray fleck best and keeps the pale colour; the dark heartwood streaks do not disappear under stain.

Sustainability and handling

Wood Database lists sycamore as not in the CITES Appendices or on the IUCN Red List, and Wikipedia's taxobox gives Least Concern (checked 2026-09-30). Wood Database says that, besides the standard health risks of wood dust, no further reactions have been associated with sycamore. The US National Cancer Institute reports strong and consistent associations between wood-dust exposure and cancers of the nasal cavity and paranasal sinuses, so extract dust and wear a respirator. US-grown timber falls under the Lacey Act.

Popular projects

Wood Database lists veneer, plywood, interior trim, pallets, flooring, furniture, pulp and tool handles and turned objects. A dealer also notes use for stringed musical instruments and cabinetry. Quartersawn boards are chosen for decorative panels, drawer fronts and tabletops.

Buying notes

Quartersawn stock is the figured product and is priced accordingly; at the sellers we checked, 4/4 sycamore ranged from about $4 to $8 a board foot. Specify quartersawn if you want the fleck, and ask whether the lumber is air-dried or kiln-dried. Check for heartwood streaks if you want even colour, and keep it indoors.
