Add some funky flair to your garden with this moulded concrete chair. It makes an eye-catching focal point in a flower bed and will bring a smile to your face every time you see it. It’s not difficult to make this decorative feature – just follow our four simple steps.
WHAT YOU NEED:
• 18 mm shutterboard (see diagram for cutting sizes)
• 1 x bag full-thread screws 4 x 40 mm
• 6 x 3 m reinforcing
• Binding wire
• PPC Surebuild 42,5 N cement
• River sand
Cordless screwdriver and attachment, fencing pliers, float, rubber mallet and a tape measure.
WHAT YOU DO:
1. Make the mould out of the shutterboard. (See the diagram for size and assembly format.) First, make the outer side (the back of the chair), using the screws to attach the three pieces of shutterboard. Then make the inner side (the front of the chair) and align the two sides, as per the diagram – leaving a 70 mm gap between them for the concrete.
2. Fix the 106 mm strips of shutterboard to one side of the chair, forming a three-sided mould. Flip the mould over, leaving the exposed side open and accessible.
3. Make the reinforcing to fit into the mould, tying the rods together with the binding wire. Ensure the reinforcingarmature is 50 mm shorter than the mould on both sides, so that it doesn’t show through the sides of the chair once the concrete is poured.
4. Make concrete, by combining 1 part cement, 3 parts stone and 2 parts river sand. Slowly add water while you turn the mixture, until it attains the consistency of thick yoghurt. Then place a 50 mm layer of concrete into the bottom of the mould before inserting the three reinforcing armatures, ensuring they are in the middle of each section of the mould. Slowly pour in the concrete, until the mould is completely filled, and use a float to smooth the concrete on the open side. Tap the mould with a rubber mallet to remove any air bubbles. Leave the concrete to cure for seven days before removing the mould. Place your chair in the garden in the position of your choice, burying the leg section 400 mm into the ground, wedged into a concrete base to secure it.
