Working with concrete is fun. You can cast anything in concrete, provided you have the right tools, materials and the know-how.
Here is a step-by-step Instructable to make a small Bedside Coffee Table in concrete, with easily available materials and tools at home. You can also find some tips on working with cement and concrete here.
Step 1: What You Need
We do not need any special equipment or form work to make this small coffee table. I have used equipment and tools commonly available in any household. I have purchased an one kilogram packet of white cement and borrowed small quantity of sand from a neighbor.
I have divided casting work of this table in three parts: The Base, the middle section and the top section.
Molds (Form work):
- A small bowl from the kitchen for the base
- An empty glass bottle for the mid section
- An ornamental plate for the top section, also from the kitchen
Poach the bowl and the plate from the kitchen, as I did, without anybody noticing them as missing and return them back after three or four days. Of course, the glass bottle is expendable...
- One kilogram packet of White Cement
- About half a cubic foot of clean river sand
- Clean water
- Little quantity of oil for lubricating the form work (the molds). I have used Coconut oil. You can use any oil.
Other equipment borrowed from the kitchen:
- A medium sized pan for mixing
- A ladle for mixing the concrete
- A small bowl for water
Step 2: Lubricate the Molds
Lubricate the Molds...
Apply any oil liberally over the surface of molds and form work which will be in contact with concrete. Without mold release, you can not take out the concrete from the molds without damaging your piece of concrete or the mold.
Here I have used coconut oil and applied it using a small piece of cloth. For the bottle, I have poured some oil inside, rolled it so that it covers entire inside surface of the bottle and then drained out the excess oil.
