Preparing for Colour
- Remove the existing finish using one of the preparation methods described here.
- If the old finish has deeply penetrated the wood, it might affect the absorption of a dye or stain - seal the surface with clear varnish and then build up colour with tinted varnish.
- Lightly sand stripped or new wood with medium-fine paper (a very fine grade could prevent even absorption). Sand in the direction of the grain of the wood - any scratches across the grain will be conspicuous after colouring.
- Use steel wool rather than sandpaper on shaped surfaces like chair spindles.
- Water-based dyes can raise the wood red cedar grain, leaving a rough finish when dry. To prevent this, wipe the wood down with a wet rag. Leave to dry, then sand smooth.
- Remove all dust, using a vacuum cleaner attachment to reach awkward crevices.
