Natural, water based grain filler for open-pore woods like ash, in stock in the UK.

Tone and Appearance

This natural grain filler has a light yellowish tone suited to ash; use it clear or tint it with compatible dyes and pigments for a custom look.

Drying and Coverage

Dry-to-sand: 2–3 hours. One 200g jar typically fills at least 2 guitars, depending on wood porosity and application thickness.

Compatible Woods

Ash, Mahogany, Rosewood, Jatoba, Paulownia, and other open-pore species.

Finish Compatibility

Suitable under common guitar finishing systems: nitrocellulose, polyurethane, and water based topcoats/sealers.

Recommended Tools

  • Sandpaper around P400 for levelling
  • Flexible scraper (e.g., old credit card) to pack pores
  • Clean cloth or paper towel to remove excess

Application

  • Apply a thin coat and work across the grain to pack pores.
  • Allow to dry, then level-sand so filler remains only in the pores.
  • Repeat a second application if the wood is very porous.

Notes

Tinting tip: Mix in compatible dyes/pigments to achieve a custom tone; test on scrap first. Looking for a coloured option? Explore the full range of grain filler for guitar.

Why use a stainable grain filler on open-pore woods?

  • Achieve a cleaner, flatter surface for a high gloss or uniform satin finish.
  • A natural, tintable filler keeps ash looking bright and lets you match any dye colour.
  • Reduce the amount of sealer and clear coat required.
  • Limit sink-back into pores after the clear coat cures.

Workflow placement

Use this water based grain filler as the pore-filling step before sealer and clear coat to improve clarity in the final finish. Available with fast UK delivery from our UK warehouse.
