Using ColorTone Powdered Grain Filler

Preparation and application instructions.


ColorTone Powdered Grain Filler is designed to fill the pores in any open-grained woods such as ash, mahogany, rosewood, wenge, walnut, koa, and many more. It will produce a smooth surface that will not shrink after finish is applied.


ColorTone Powdered Grain Filler comes in a powder form. To prepare it mix 1:2 parts water to powder, then thin or thicken based on your needs. Mix thoroughly until the consistency of the filler is smooth, without any lumps. If applying with a brush, mix to a ketchup consistency, no thicker than sour cream. If applying with a card, mix to a viscosity between sour cream and peanut butter.


1. Prepare surface by sanding to 220-grit. Remove all dust, oil, and solvents from the surface.

2. Brush on the prepared ColorTone Powdered Grain Filler liberally in the direction of the grain, then against it. Allow to dry for 5 to

10 minutes depending on thickness of the prepared filler.

3. Use a grain filler spreader or plastic card to squeegee off excess filler. Wipe at a 45 angle to the grain.

4. When dry, wipe off remaining residue with a clean dry cloth.

5. Sand surface with 320-grit sandpaper. Clean up with warm water.


  • If additional filling is required, allow 1 hour drying time between fills.
  • ColorTone Powdered Grain Filler can be tinted for custom colors using ColorTone liquid stains or waterbase pigments before application.
  • Allow to dry 2-4 hours before applying waterbase finishes, 24 hours before applying nitrocellulose.
  • ColorTone Powdered Grain Filler has an unlimited shelf life. Keep the pouch sealed and away from moisture when not in use.
  • Non toxic, no harmful fumes.
  • As with all finishing products, use in well ventilated areas. Avoid inhaling residue.
