Stud / Partition / Hollow Walls
Walls constructed of timber studwork covered with plasterboard require different fixing techniques from those used for solid walls. You cannot use standard wall plugs as these simply won't hold firm in the plasterboard and will quickly work loose when any pressure is applied.
1. Always check with a detector that there are no pipes or cables hidden in the wall beneath the area to be drilled. When drilling always wear suitable safety goggles.
Fixing into Timber Studs
2. If at all possible, locate the timbers within the wall and line up your fixing points with these. To locate them, gently tap the surface until you hear a muffled sound indicating the presence of solid timber behind. If you work your way across the wall where you want to make the fixings, you should be able to fairly accurately identify the position of the upright timber studs.
Fixing into Plasterboard
6. If alignment with the timber studs is not practical, special hollow wall fixings will be required. Ordinary wall plugs will not do since they rely on a sideways force within the wall. Remember that you are relying only on the strength of plasterboard to carry the load, so heavy items cannot be fixed in this way.
Types of Hollow Wall Plugs
7. There are many different hollow wall fixings available so you will need to check out their suitability for your particular situation.
9. Some have metal or plastic lugs which open out on the other side of the plasterboard spreading the load and providing improved strength. The bottom wall plug in the picture shows how it looks before tightening. The screw in the top plug has been tightened and you can see how the plug is now gripping the surface.
Choosing the right screws for plugs
11. As with all plugs, the size of screw will be specified, as will the acceptable thickness of the item to be fixed. There may also be information as to the maximum load acceptable on each plug. Follow these carefully to ensure a good fixing.
13. Tighten slowly to the point where a solid fixing is obtained. Do not over tighten.
