Sand‑In Gunstock Finishing Technique as used by the gunmakers at TAG and ASA.

This method uses fine abrasive dust and oil to create a slurry that fills pores and produces a deep, traditional English finish.

Prepare the Stock Surface

A clean, open‑pore surface ensures the oil and sanding slurry can penetrate properly.

  • Ensure the stock is fully stripped of old finish

  • Sand to 220–320 grit depending on wood density

  • Remove all dust with a tack cloth or compressed air

Apply a Thin Coat of Oil

The first coat provides lubrication for the abrasive and begins penetrating the grain.

  • Rub a small amount of oil into the wood with your palm

  • Warm the oil by hand friction for deeper penetration

  • Do not leave excess oil on the surface

Wet‑Sand With Fine Abrasive

Key Step

Sanding creates a slurry of oil and wood dust that fills the pores.

  • Use 400–600 grit wet‑dry paper

  • Sand with the grain using light pressure

  • Allow the oil to mix with the sanding dust to form a paste

Work the Slurry Into the Grain

The slurry fills pores and levels the surface for a smooth, traditional finish.

  • Push the slurry across the grain to force it into pores

  • Continue until the surface feels uniformly smooth

  • Add a drop of oil if the slurry becomes too dry

Remove Excess Slurry

Removing surface residue prevents streaks and ensures an even cure.

  • Wipe gently with the grain using a clean cloth

  • Leave only what remains in the pores

  • Do not buff to shine at this stage

Allow the Coat to Cure

Dry Time

Proper curing builds depth and durability in the finish.

  • Let the stock rest overnight or 12–24 hours

  • Ensure it cures in a dust‑free environment

  • Avoid touching the surface during curing

Repeat for Depth and Smoothness

Multiple sand‑in coats create the classic English hand‑rubbed finish.

  • Repeat steps 2–6 3–6 times depending on pore size

  • Switch to 800–1000 grit for final coats

  • Stop when pores are filled and the surface is glass‑smooth

Final Wax or Oil Topcoat

A final protective layer enhances sheen and seals the finish.

  • Apply a thin coat of stock wax or finishing oil

  • Allow to haze, then buff lightly

  • Maintain with occasional waxing
