Design and Technology (D&T) KS3: Finishing wood
This video explains the most common ways to give wooden items a polished, professional finish.
Points for discussion
- Why do we start with course glass paper and use finer grades sequentially to achieve the finish?
- When is an item finished? Discuss quality control and management in projects.
- Why you would choose one finish over another, for example wax vs wood stain, polyurethane varnish vs paint?
- In what order do we carry out processes? Do we varnish before or after assembly? Why?
- Discuss time in project management. How long does it take to achieve a truly professional finish as opposed to a finish you are happy with?
- Discuss when you would use hand finishing techniques over a hand sander, belt sander or bobbing sander.
- Discuss what constitutes shaping and what constitutes finishing an item.
- Have a wider discussion about the type of wood most suitable for various applications, for example door knobs, children’s toys, furniture & etc.
This process complements any wood-based product, for example:
- The outside finish on a trinket or jewellery box.
- Sanding techniques in the finishing a vacuum forming mould.
- Applying the appropriate finishes for a KS3/4/ design and make project.
- Design the type and shape of sanding block used to create different shapes, for example convex or concave curve.
- How can these processes be adapted to finish very small components?
Suitable for teaching Design and Technology (D&T) at KS3/KS4 in England, Wales and Northern Ireland, and 3rd and 4th levels in Scotland.
