A concrete desk is one of the best stuffs you should try to make. In addition to the fact that it will be beneficial for daily use, this project is simple enough as long as you know the steps. Learn from the instruction below to make it like a pro.
Step 1. Plan and layout the desk
Before doing anything else, make some plan and also layout for your desk. Get the location measurement of where you will display the desk. For this concrete desk design, you have to ensure that the concrete can be managed into several pieces to avoid any fractures and also to help carrying it safely into its display location.
Step 2. Prepare the materials and tools
- Drawer pulls
- Drawer slides
- Silicone caulking tube
- Acrylic concrete fortifier
- Spray adhesive
- Glass fiber
- 6 – 50lb bags of washed plaster sand
- 2 – 94lb bags of cement
- 2 – ¾” melamine
- Some birch plywood
- 1 – lyptus plywood
- 30 to 35 ft of Lyptus wood
- Fiber optic cables
- Crushed glass
- Other decorative items
- Woodworking tools
- Concrete working tools
- Polished pad set
- Waterproof or air powered angle grinder
Step 3. Build the desk frame
The construction of the desk frame is being shown from the pictures. Generally, the desk is made of lyptus wood as it is the combination of Mahogany and Eucalyptus wood. The desk is designed with two shelf cabinets in which the cabinet ends are used to support the center frame and the pencil drawer.
The main structure of the desk is two thick woods. The cabinets are made from panels which are attached onto a piece of plywood necessary for the project.
Step 4. Build the concrete desktop
The form for the concrete is made of ¾” melamine sheet. The height of each side of the form is 2” to make sure that the concrete is strong. Then, measure the width and length of the desk. Make the mold based on the measurement. To make the concrete, insert silicone on each corner to create edge for the concrete form during the molding.
Step 5. Give additional supports and decorative objects embedded in the concrete
Add some wire mesh supports and also any decorative embedded items that will appear on the desk surface later on. Make one hole on the desktop particularly at desktop center.
For this project, the concrete is made of some colorful glass blobs and fiber optic cables. To insert the fiber optic cables, drill some holes throughout the melamine, insert the cables and then glue the cables onto the other side.
You can do the same thing with the fibers. These cables and fibers will be going into the light box. These fibers and cables will be like stars on the desktop surface.
Then, spray all cables and fibers using spray adhesive to hold them in place so that they won’t be pushed around when the mold is being poured into the melamine form.
Step 6. Pour the concrete mold
Mix cement and sand with 1:3 ratio. Then, add some water until the mixture is like thick oatmeal. Pour this mix into the form evenly. Try not to make any bubbles. Then, mix the concrete with glass fiber. Pour the mixture evenly into the melamine form. Leave one day for drying process.
After one day, cover the mold with wet towels to add more strength and also to slow the hardening process. Wait for 3 days to unmold the concrete.
When you want to unmold the concrete off the form, you can use a shovel. Place some bricks under one side of the form to lift it. It can help you with the peeling off process.
Step 7. Grind the surface and fill the holes
If the slab has many voids and holes, you can grind the surface away and show off the glass and also the embedded items. The reason for grinding the surface is to open up any holes.
You can later on fill the holes with other mixture of cement and acrylic fortifier. Then, after the surface is dry completely at least one day, you can grind the surface with 50 or 100 grit of polishing pad.
Step 8. Polish the concrete
Polish the surface until you reach 1500 grit. Make sure not to gauge the desktop surface with the grinder. After the surface is being polished well, you can add some sealer and let it dry. You can also add some coats. Shine the surface using paste wax and then wipe it off using towel or cloth after dry.
Step 9. Assemble the desk
Secure all joints of the desk using bolts. Then, place the concrete top. After that, insert the drawer pulls, or the power strips, or any other items to finish the desk assembly.
