- Intensity of colour is controlled by strength of dilution.
Preparation: Dissolve the crystals in hot water (about 100 g to 1 L). Test the color on a spare piece of wood, darken by adding more crystals and lighten by adding more water. To obtain different shades Liberon Concentrate Water Based Dyes can also be added to the solution. Or the solution can be added to Liberon Palette Wood Dyes or Liberon water based varnishes.
Application: Ensure the surface is bare, dry and free from dust. Apply with a brush or sponge and wipe of excess with a cloth. Allow to dry for at least 12 hours, then rub down lightly with abrasive paper 240 or 320 grit.
Important: Always test product on a spare surface or inconspicuous area for color, compatibility and end result.
