I’m planning to make some floating shelves 150 cm wide and 30 cm deep.
I want to mount them on a wall that has a plasterboard of thickness 13mm behind which is a plywood backing of 15mm according to the details provided by the contractor (see the attached image). This construction was apparently intended for hanging TVs and they recommend using wood screws that are not longer than 30mm.
One of the shelves will have my record collection which could weigh between 25-50kg. What are some options for hardware I can use to mount the floating shelves?
Ah gotcha. Well I’m pretty sure there are studs on the right half of the wall (the left half has space for a pocket door). I think there are two but my stud finder is not very good and I’m not sure if they’re wood or metal studs.
