Maritime Pine

Pinus pinaster is the pine of the western Mediterranean and the Atlantic coast of Iberia and France. The Landes forest in southwest France is the largest planted pine forest in western Europe and the main commercial source. Portuguese and Spanish material is also common in the EU market.

Maritime Pine works fairly well with most tools, and then the resin asserts itself.

It gums blades faster than larch, which is saying something. It loads abrasives so quickly that sandpaper should be budgeted as a consumable rather than a tool. Saw gullets pack. Plane soles need clearing. None of this is difficult, but all of it is constant, and a schedule built on pine machining speeds will run over.

There is a second, subtler machining problem. Because the earlywood bands are wide and much softer than the latewood, abrasives cut the soft bands away faster than the hard ones. Sand a Maritime Pine face flat and you get a washboard: a rippled surface that catches light unevenly. The fix is to produce the final surface with a sharp plane or a card scraper and use abrasives only lightly, if at all.

Drying and movement#

This species moves more than anything else KORENA lists. Volumetric shrinkage is around 14.4 percent, with tangential movement at 9.0 percent against 4.5 percent radial, a ratio of two to one that guarantees flatsawn boards will want to cup.

It also dries with a tendency to distort, driven by the wide rings and frequent spiral grain of fast grown stock. A hot kiln schedule compounds the problem by drawing resin to the surface, where it sets sticky and sabotages the finish months later.

Air drying under cover followed by a low temperature kiln finish is the route that works. Ask the yard what schedule was used, and let any slab acclimatise in its final room for a couple of weeks before final flattening. On a KORENA listing the drying method and measured moisture are recorded, so this is checkable rather than a matter of trust.

Finishing#

Start with a solvent wipe. Denatured alcohol or acetone across the surface, allowed to flash off, lifts the mobile surface resin. Skip this and an oil finish will cure unevenly and stay tacky in patches, which is a fault that only appears after the work is otherwise done.

Once clean it takes oil and wax well. Pigment stains blotch severely here, worse than on any other pine, because the density contrast is so extreme. Use a dye or leave it clear. Seal knots with shellac before any painted finish.

Where Maritime Pine is the right answer#

Rustic tabletops, panelling, carcass work and shelving where the bold coarse figure is wanted and the movement can be designed around. It is inexpensive, widely available and honest about what it is.

It is the wrong answer for fine work, for anything requiring dimensional precision across a wide panel, for a surface that must stay unmarked at 1,740 N Janka, and for any project where the finishing schedule cannot absorb the extra solvent and cleaning steps.

Sourcing and EUDR#

Not CITES listed and assessed as Least Concern. The Landes plantations are intensively managed with good certification coverage, so documentation is straightforward and supply is reliable. The one thing to be aware of is fire. Large burn events in southwest France and Iberia periodically push significant salvage volumes into the market, and salvage material is legitimate but should be identified as such rather than discovered on arrival.

At 1,740 N Janka it is soft, close to Norway Spruce and well below Scots Pine at 2,420 N. It makes a rustic tabletop that will dent and record use. For a surface expected to stay unmarked, choose a hardwood.
