A floating corner shelf has many purposes and is quite popular in the home, due to its clean finish, and ability to make use of dead space. While a floating corner shelf is a lot sturdier than they look, due to their lack of visible supports, it would still be unsafe to place a large TV on a shelf, as it could fall. Therefore, if you were to make a floating corner shelf for a TV, then it would need to be a small, flat-screen TV, for safety purposes. If you want to put a large TV on the wall, then use a shelf with brackets.

Step 1 – Prep Work

First, you need to check that the TV is not too heavy for the shelf, it is advisable to not put anything heavier than 30 pounds on a floating shelf. Second, read the manufactures guide or call the manufacturer to find out what space is required around the appliance as a safety precaution. Third, mark on the wall the length of the floating corner shelf, check that the line is straight with a spirit level, and note down on a piece of paper the dimensions.

Step 2 – Cut the Wood

Cut the wood using a circular saw based on your measurements in the previous step. You will need to cut the shelf top and the shelf front edge. You will also need to cut 2 pieces of wood to run along the wall to act as brackets.

Step 3 – Install Brackets

Using a stud finder, locate the studs in the wall, this is where you will screw the blocks of wood into the wall using long screws. The purpose of using a wooden ridge as a bracket, rather than shelf arms, is the shelf arms will not be able to get close enough to the corner of the wall or the end of the shelf to provide good support.

Step 4 – Making and Mounting

Secure the front of the shelf onto the top of the shelf. The front piece of wood will overlap the edge of the top piece, for a flush finish. Use wood glue, as it is quite forgiving, and then secured in place with nails. Finally, place the floating corner shelf on the brackets, and check that the shelf is flush to both walls.

Step 5 – Finish the Shelf

Now that you know the shelf fits, it is time to finish it. First, sand the floating corner shelf to make sure it does not have any splinters. If you are painting the shelf, then 2 coats will be needed and the sanding will give the paint a good base to adhere to, so the finish lasts longer. Alternatively if you choose to varnish, apply 2 or 3 coats in your desired shade. 

Step 6 - Secure the Shelf

Once the shelf has dried, place the shelf back on the brackets, and screw them securely in place. It is easier to screw from the top down, but it is neater to screw from the bottom up as long as you do not go all the way through the floating corner shelf top.
