If you’ve ever worked with green oak – whether in beams, peergola, gazebo, truss – you’ll know it has a life of its own. Freshly cut oak is full of moisture, and as it dries it shrinks, twists, and develops cracks. This natural movement often leaves people asking: “Can I just use a timber filler to fix the cracks in green oak?
The short answer: no, not if the oak is still green. Why Filler Doesn’t Work on Green Oak
High moisture content. Green oak can contain 60–80% water. As it dries, it will shrink significantly. Any rigid filler will simply crack and fall out.
Movement and checking. Cracks in green oak are natural and part of the seasoning process. They don’t usually weaken the timber.
Tannin staining. Oak is rich in tannins, which can react with some fillers and leave dark stains.
Recomendation. Leave it alone. Traditional oak framing is designed to move. Cracks and splits are expected, even celebrated, as part of its character.
Wait to fill. Let the oak season for at least 12–24 months before attempting filler or resin repairs. READ MORE ABOUT RESIN
Design for movement. In construction, joints and details should allow oak to move naturally without forcing repairs.
Best to wait until the oak has dried before using fillers or resins.vUsing filler on green oak is usually a waste of time. Let the oak dry, embrace the natural cracks, and only use filler later if absolutely necessary.
Photo 1. A close-up of a corner joint in a green oak post. A filler has been applied into a surface crack, but it is already pulling away from the timber. The surrounding wood shows natural shrinkage cracks, highlighting how movement in green oak causes fillers to fail.
Photo 2. The end grain of a green oak beam with large radial cracks. A filler has been applied in the centre, but it is breaking apart and separating from the wood. This clearly shows that fillers cannot cope with the significant shrinkage and movement of green oak during drying.
Damaged or severely split beams are inspected at the factory and replaced at no extra cost. If beams split on site, we will also replace them.
