Pinus sylvestris
Scots Pine
The most widely distributed pine on earth and the most forgiving wood in this catalogue to build with. Soft, knotty, and it ambers into something far better than it starts as.

Træets udseende
Sådan ser det ud
Pale yellow to light reddish brown heartwood that darkens considerably with age and light, against a wide band of near white sapwood. The ring figure is pronounced and the knots are a defining feature rather than an incidental one, since Scots Pine is naturally knotty and much of its character in furniture comes from that. Older slow grown stock develops a deep amber colour that is the reason antique pine looks nothing like new pine.
- Pale yellow to light reddish brown heartwood
- Wide near white sapwood band
- Darkens markedly with age and UV toward deep amber
- Generally straight; moderate resin.
Bearbejdning
Bearbejdning
Easy with both hand and machine tools and it glues and finishes well, which together make it one of the most forgiving woods to build in. Resin is present but less troublesome than in larch or maritime pine. Knots are the real machining consideration: they are hard, often loose, and can tear or spit out under a planer. Around large knots, take light cuts and consider hand work.
Overfladebehandling
Takes finish well and takes wax exceptionally, which is the traditional treatment and still the best one for the look most people want from pine. Pigment stains blotch on pine as they do on spruce, so use a conditioner or choose a dye. Resin around knots should be sealed with shellac before painting or it will bleed through the film. The natural ambering with age is substantial and generally considered the point.
Tørring
Dries fairly quickly and easily with a low tendency to distort, one of its practical virtues. Blue stain from fungus develops fast in warm damp conditions on freshly felled logs and unseasoned boards, so stock that has sat before processing may carry grey blue discolouration through the sapwood. It does not weaken the wood. Volumetric shrinkage is around 13.6 percent, on the higher side for this group.
Hvor meget bevæger det sig?
Træ udvider og trækker sig sammen på tværs af bredden, når luften bliver fugtigere og tørrere. Beregn den forventede sæsonbevægelse i en bordplade af Scots Pine, før du udformer beslagene.
Forventet sæsonbevægelse

Fastgør bordpladen med sargklodser eller beslag med langhuller, ikke med lim eller stramme skruer.

- Status på IUCNs rødliste: den globale bevaringsvurdering for denne træart.
Working with pine has been reported to cause allergic skin reactions and asthma-like symptoms in some people. Resin contact sensitises some individuals over time. Normal extraction, a P2 mask for extended sanding, and gloves when handling resinous stock are appropriate.

What Scots Pine actually is#
Pinus sylvestris has the largest natural range of any pine species anywhere, stretching from the west of Scotland and the Iberian mountains across the whole of Eurasia to the Pacific coast. It is sold under several names that confuse buyers comparing quotes: redwood in the British trade, deal in older usage, and simply pine almost everywhere. They are the same species.
Its ubiquity has the same effect on its reputation as spruce suffers from. This is the wood of construction studs and cheap furniture, and that association hides the fact that Scots Pine is one of the most pleasant woods to build in that exists, and that it ages into a colour no finish can imitate.
Reading a Scots Pine slab#
Fresh Scots Pine is pale, a light yellow heartwood against a wide near-white sapwood band. What you are actually buying is what that will become. The species ambers dramatically under light and time, moving to a deep honey brown over years and decades. Stripped antique pine holds a colour that new pine stained to match will never quite reach, because the change is oxidation and resin migration through the whole thickness rather than pigment on the surface.
Knots are the second thing to read, and on this species they are not a defect to be tolerated so much as the material's defining texture. Scots Pine is naturally knotty. The question is whether the knots on a given slab are sound and tight, or loose and ringed with checking. Sound knots are a feature. Loose knots will eventually fall out and need filling or plugging.

Why does old pine furniture look so different from new pine?
Scots Pine ambers dramatically with age and light exposure. A freshly machined board is pale yellow; the same board after decades of daylight and wax is a deep honey brown. That colour is not a stain, it is oxidation and resin change through the wood, which is why stripped antique pine keeps its colour while new pine stained to match does not age the same way.
Is Scots Pine hard enough for flooring?
At 2,420 N Janka it is soft for a floor and will dent, which is precisely the look traditional pine flooring has. It has been used for floors across northern Europe for centuries on that understanding. If dents are unacceptable, oak or ash are the right answer; if a floor that records its use is wanted, pine does it honestly.
What causes the grey blue staining in the sapwood?
Blue stain fungus, which colonises freshly felled pine in warm damp conditions. It discolours the sapwood without weakening it structurally. Some makers avoid it and some feature it. It is a cosmetic grade issue, and any KORENA listing showing it will show it in the slab photography rather than describing it away.
