Building a Floating Shelf
Learn how to design, cut, and mount a floating shelf that carries up to 25 kg. This guide covers stud finding, selecting the right hardware, cutting and finishing the board, and achieving a perfectly level result in any room.
Plan and Locate the Studs
Decide on the shelf dimensions and height. Use a stud finder to locate the wall framing behind the plasterboard — screwing into studs gives you a load-bearing fixing rather than relying on plasterboard anchors alone.
Cut the Shelf Board
Cut your selected board (18 mm plywood, MDF, or solid timber) to the desired length. Sand all edges smooth working from 80 grit up to 220 grit.
Install the Wall Bracket or Ledger Batten
For invisible floating hardware, drill pilot holes into studs and attach steel rod brackets. For a visible ledger style, screw a timber batten directly into the studs.
Finish the Shelf Board
Apply primer followed by two coats of paint, or two coats of stain/varnish for a natural timber look. Finishing before mounting is easier and gives better coverage.
Mount the Shelf and Check Level
Slide the shelf board onto the hidden rod brackets, or screw through the back edge into the ledger batten. Set a spirit level on top and make any final adjustments.
