A lamp from concrete easily can be made by yourself with quite simple tools and materials. Of course there are some steps must be noted to achieve good results. Exactly these steps I would like to show in a short video.
I would be pleasured if you would share your experience of making the lamp of concrete with me.
Here you can download the template as a PDF file for free.
Step 1: Download
For a precise work I have prepared for you a drawing as a PDF file which contains measurements I used. The drawing can be downloaded here free.
First you will need a wooden board which is 14cm wide and 80cm long. From this board you need to saw five pieces with following dimensions:
4 pieces 14x16cm
1 piece 14x14cm
Therefore you can use any electric saw or a hand saw.
Step 3: Assembly
After you have sawed out all the pieces drill the holes at each position where you will set screws. Do not forget to drill a hole for the wire on any sidewise pieces. Now screw all the wooden pieces together to a box. All the inner joints of the assembled box have to be sealed with silicone so that water cannot escape.
Step 4: Socket
Stick your lamp socket on a piece of double-side tape and cut out cleanly the overcoming tape. Remove now the cover paper of the other side and glue the socket centrical on the bottom inside the box.
Tip: Mark previously the position of the lamp socket. It will be important to place the socket correctly the first time so that the tape adheres better.
Step 5: Wire
I would recommend you to use a part of a pipe to put the wire through the wooden hole. With that firstly the textile wire will be protected and secondly water will not escape later. Finally mask all the places on your lamp socket with waterproof tape where water maybe can get through. That will be necessary in order to keep the socket clean and dry from the inside.
Step 6: Concrete
Now it gets exciting! You need approximately 6kg of ready concrete mixture. Depending on which concrete you are using pay attention to the correct volume of water and to the manufacturer’s notification.
Step 7: Fill Concrete
When the concrete is mixed, fill it into the box slowly. Knock and shake the box frequently while you fill the concrete to avoid air inclusions.
Step 8: Drying
Only after 48 hours the box can be disassembled carefully.
Step 9: Connect Wire
Now you need only to connect the wire and your concrete lamp is ready.
Attention: If you are not well informed of electricity you have to get a specialist to plug the electric cable.
