How to determine the thickness of your plasterboard

You should only measure the thickness of the plasterboard and not include the thickness of the insulation backing. If your plasterboard has an insulation backing, the thickness you need to know is only that of the plasterboard and not the thickness including the insulation backing.
Metal hollow wall anchor legs collapsed against back of plasterboard This is because as the collapsing legs of the hollow wall anchor fold back, they will squash and sink through the insulation backing before fixing on the back of the plasterboard.
Tools needed to measure the plasterboard thickness of an existing stud wall are: drill, small drill bit wire and tape measure. You will need to do a little more work to determine the thickness of the plasterboard on an existing stud wall. In order to do this you will need the following tools: a drill and small drill bit, a piece of wire, electrical tape or similar, a stud finder or some strong magnets and a tape measure or ruler.
Using a special stud finding tool is the easiest way of locating the studs within a wall.

Step 1 – Find studs

To measure the plasterboard thickness you will have to avoid the sections of the wall where the studs are located. The easiest way to find the stud positions is to use a special stud finder tool.

Rare earth magnets can be found in old computer hard drives. If you do not have a stud finder, another way of locating the stud positions within a wall is to use magnets. These will have to be strong magnets such as rare earth magnets: a good source of these is old computer hard drives.
Strong magnets can be used to find the stud positions within a wall. Rub the magnet over the wall until you feel some resistance and the magnet sticks. It will do this once it is positioned over one of the screws that has been used to fix the plasterboard to the studs. Mark this position with a pencil and then run the magnet up and down to find the next screw and mark that position.
Knock on the stud wall and listen for a hollow sound that indicates there is no stud present behind the plasterboard. Alternatively, you can always use the old method of giving the wall a tap and listening for a hollow sound that will indicate there is no stud present behind the plasterboard.
Drilling a small hole in the plasterboard of a stud wall.

Step 2 – Drill small hole

Once you know where the studs are in the wall, drill a small hole through the plasterboard, avoiding the studs. Try to do this on an area of the wall that is less visible, such as behind where you intend to place a picture.

Bend your wire so that it is straight with a 90 degree hook at the end

Step 3 – Bend wire

Take a thin piece of wire such as a paper clip, and bend it so that it forms a straight line with a small 90 degree hook bent at the end.

Pushing wire with bent hook at the end through the hole drilled in the stud wall.

Step 4 – Push wire through hole

Push the piece of wire you have bent through the hole you have drilled in the wall. Then pull the wire back until the hook you formed at the end latches onto the back of the plasterboard.

Use tape to mark the point of the wire where it emerges from the hole in the wall.

Step 5 – Mark wire length

Using some tape mark the position on the wire where it emerges from the hole.

Measure from the hooked end of the wire to the tape to determine the thickness of the plasterboard.

Step 6 – Remove wire and measure

Remove the wire from the hole, being careful not to bend it as you do so. Using a ruler or tape measure, measure the distance from the hook at the end of the wire to the point marked by the tape. This distance is the thickness of the plasterboard on the stud wall.

How to fit a picture hook using a metal anchor expansion tool

Decide on what position you want your picture hook to be placed.

Step 1 – Decide on position

First make sure you have determined the thickness of your plasterboard and selected the appropriate size hollow wall anchors for your job. Then decide where you want to place the picture hook on the wall.

The drill bit size you should use will be displayed on the pack of hollow wall anchors.

Step 2 – Drill hole

Using the correct size drill bit for your hollow wall anchors (this should be clearly indicated on the pack) drill a hole where you want the picture hook to go. Be careful not to drill too far into the wall as there may be pipes of wires hidden within the wall cavity.

The process of fitting a hollow wall anchor begins by inserting it into the hole you have drilled.

Step 3 – Insert hollow wall anchor

Push the hollow wall anchor into the hole you have drilled.

The screw head of the hollow wall anchor may need to be slightly unscrewed to give a gap between it and the flange in order to fit the metal anchor expansion tool.

Step 4 – Connect metal anchor expansion tool

Connect the metal anchor expansion tool to the hollow wall anchor. To do this, you may have to back the screw out from the hollow wall anchor slightly with a screwdriver, so there is a slight gap between the screw head and flange of the anchor.

The metal anchor expansion tool should be positioned so that the support surface is touching the plasterboard and the screw head is sat in the U-shaped pulling arm. The support surface of the metal anchor expansion tool should be pressed up against the flange of the hollow wall anchor and the plasterboard, while the back of the screw head should sit inside the U-shaped pulling arm.
Compress the handles of the metal anchor expansion tool together to collapse the legs of the hollow wall anchor and set it in the plasterboard.

Step 5 – Compress handles together

Compress the handle of the metal anchor expansion tool together. If you are using a model with a ratchet mechanism, you may have to do this several times until you feel resistance from the hollow wall anchor, signifying it has set in place.

Once the hollow wall anchor is set you need to remove the metal anchor expansion tool. If the model you have used has a ratchet you will have to press the ratchet release lever or button to release the tension on the hollow wall anchor and screw in order to remove the tool.
Once the hollow wall anchor has been set in the plasterboard remove the screw and attach your picture hook before refitting the screw in the hollow wall anchor.

Step 6 – Remove screw

Using a screwdriver, remove the screw from the hollow wall anchor. Place a washer followed by the picture hook on the screw and then replace it in the hollow wall anchor. Once you tighten the screw up you will be ready to hang your picture.
