Create a wall clock

You will need:

•  PPC cement
• Container to mix in
• Small shovel to mix with
• 500 x 500mm melamine
• Masonite strip + - 70mm X the circumference of your shape
• Nails or screws to make the mould
• 3 x M8 bolt and nuts
• Old washers or bolts
• Scrap wood for spacers
• 700mm chain
• Clock mechanical box and watch hands
• Sealant or paint to seal the concrete

Steps:

1. Start with your mould. Using plywood, supawood or melamine, cut out the shape you want for your clock. Using screws or nails, add your masonite strip all around to create a mould.
2. Using some scrap wood, position 2 bolts close to the edges – these will be for mounting the clock. You can add some old washers or bolts to give the bolt more grip in the concrete.
3. The middle one is to create space for your mechanical box, and to create a hole in the middle for the watch hands to connect to the clock mechanical box. Use scrap wood to create a space to sink the box into the concrete.
4. Position it in the centre or wherever you want your watch hands to be, and seal the edges using silicone or duct tape.
5. Mix your PPC concrete according to instructions, to a consistency of peanut butter. Full up your mould making sure you tap and shake the concrete into all the edges and conners. You want to see air bubbles escape.
6. Cover with plastic and let it dry for at least 48 hours. Once dry, you will notice a much lighter colour. Now you can remove the mould.
7. Add your chain and secure it with bolts. Install the watch mechanical box and hands and you are ready to start decorating your clock as you wish.
