Eralier today I put up a floating shelf in the bedroom.It is on the wall between the bedroom and bathroom on plasterboard.I used the rawl plugs provided with the shelf.I am a little worried about it the way the screws went in and the way the shelf is sitting.
Any advice?
I'd not risk cavity fitting plugs to hold up a shelf and it's contents. I dislike intensely these drywall plaster things anyway, I prefer a proper brick wall, but given that is what you have to work with, find the noggin that the plasterboard is fixed to, and drill your holes into the middle of that. It restricts where you can put the shelf, but at least it is less likely to fall down taking a chunk of plasterboard with it.
You need to find the timber uprights in the wall, Marwel.
Draw a pencil line where the shelf will be, use a small drill to drill at points along the line until you find an upright.
The others will be 400mm apart.
No rawlplugs needed. Just screw into as many of the uprights as you need (depending on where the brackets go.)
The shelf will hide all the drill holes.
