Hanging a mirror to plasterboard

The modern method of dry lining interior walls using the dot and dab method, and internal stud partition walls with 12mm (half inch) plasterboard present a problem when trying to hang large mirrors in the exact position required, because behind the plasterboard there is a void.

There are a couple of mirror fixing options available, the first is commonly known as a Redidriva. This type of fixing involves a large coarse screw, which can be in plastic or metal with an attached centre screw, which is used to drive in the coarse female part of the fixing. The fixing screw is then undone and taken out of the housing, to be used for the actual fixing of the item.

Another device is known as a hollow wall mirror anchor. This method will provide a very secure fixing in a plasterboard or hollow wall, but unfortunately requires a special setting tool, which is a little expensive if you are not a frequent user.

The centre machine screw of this type of fixing is available in various lengths, following the manufacturer's instructions, the method is to drill the appropriate sized hole, where required, push in the anchor, use the setting tool which grips around the head of the centre machine screw and with pressure applied, squashes the anchor behind the plasterboard.

The centre machine screw can then be withdrawn to be used again as the fixing screw, or used as a mirror hook for a string line or wire for the mirror or picture or could be used in conjunction with mirror plates if required.
