Sawdust wood filler paste
Woodworkers have always kept a tin of sawdust near the bench for one reason: mixing it with glue creates a filler that shrinks, sands and stains exactly like the surrounding wood. Because the filler is made of the same material as the piece, it accepts color matching far better than commercial fillers, which often stay as a visible pale line.
What you need
- Fine, dry sawdust (ideally from the same wood species you're repairing)
- White glue (PVA, the common school and woodworking glue)
- A small container or palette knife for mixing
- Sandpaper in medium and fine grits
How to make it
-
1
Collect fine sawdust, sieving out coarse splinters if needed — fine particles pack tighter and sand smoother, so the repair disappears into the surface.
-
2
Mix sawdust with white glue, adding powder gradually until you get a stiff, peanut-butter-like paste that holds its shape without sagging.
-
3
Press the paste firmly into the hole, crack or gouge, slightly overfilling it — pressing compacts the mix, and the excess will be sanded flush later.
-
4
Let it dry completely, usually several hours or overnight, because PVA glue cures as water evaporates and sanding too soon just smears it.
-
5
Sand with medium grit until level with the surface, then finish with fine grit following the wood grain for a seamless patch.
Finishing touches
Stain or varnish over the patch and it blends in beautifully; for darker woods, stir a pinch of pigment or a drop of stain into the paste before filling to match the tone from the start.
