Concrete Sundial

What you will need:

  • Round rubbish bin lid
  • River sand (to stabilise the lid)
  • Small paintbrush
  • Cooking oil
  • Spirit level
  • Steel Trowel
  • Plastic trowel
  • 2 buckets river sand (for the mixture)
  • 1 bucket cement
  • Small white stones
  • Steel pointer

What to do:

  1. Find an ordinary round rubbish bin lid
  2. On a flat board, use river sand to stabilise the lid and keep in place
  3. Mix 2 buckets of river sand to 1 bucket of cement then add water to form a damp  mixture
  4. Use a brush to coat the lid with a releasing agent – you can use normal cooking oil.
  5. Pour the mixture into the lid all the way to the top ( using a trowel to agitate & compact the mixture)
  6. Use a flat piece of plank to level the top, then with a plastic trowel to smooth the top and finish it off with a steel trowel.
  7. Find the middle of the mould (vertical- you can use a spirit level/plank) and make a mark at the top & bottom of the mould and also find the horizontal middle of the mould and mark each side.
  8. Using white little stones, start placing the Roman numerals onto the wet mould. Start by putting down twelve and then following up with placing six on either side of the twelve in the top half of the mould. Then continue to fill up the missing numbers ( 11 – 5)  between the twelve and six of both the PM & AM sides (make sure the marking stones are not too close to the edge)
  9. Find the centre of the mould and then insert a pointer. Leave it dry.
