Dyeing and then spraying with lacquers – acrylic or cellulose-based – can bring out the figuring and burr detail that would, at times, be a bit lost if you choose to not colour the wood. Masur birch (Betula pendula), horse chestnut (Aesculus hippocastanum)>, sycamore (Acer pseudoplatanus) and maple (Acer campestre) burr, and the roe figuring on silver birch, are just a few examples of timbers that can work well with this type of treatment.
Below you will find some pointers on how dyeing and spraying can enhance your work.
Turn your piece to the shape required and fill any major defects or fissures, unless you want to go for a more rustic look. Sand the piece down to a minimum of 400 grit, but go to 800, if possible
Now stain the wood – I prefer spirit stain. I only use one colour here, but you can use multiple colour washes. I prefer a subtle colour wash rather than a full-blown concentrated dye. I dilute mine with cellulose thinners – 100:1 – this enhances the grain or burr without drowning it in colour. Leave this to dry before you see the true colour. If the colour is too light then you can re-coat
Once fully dry and when you are happy with the effect, coat the piece with cellulose sanding sealer diluted 50/50 and leave to dry. Once dry, sand lightly up to 600 grit then coat with neat sanding sealer, leave to dry, and then sand with 800 grit abrasive
Now apply the lacquer. I find aerosol or sprays are better, but make sure that as you apply them, you turn the lathe by hand whilst spraying over the complete piece. Continue to slowly turn the piece by hand until the piece is tack dry. Once dry, sand with 600 grit, re-spray, then leave overnight to dry
The last stage is to use a burnishing cream or a buffing wheel system to create the desired lustre
