The hazards of inserting screws into a plaster wall is that eventually the screws will work their way free from the plaster. This is dangerous, especially if the item being supported by the screws falls on someone. Furniture and the wall itself can also be damaged by the falling item. Wall anchors will ensure that the screws stay in the wall where they are inserted. The best wall anchor to use in a plaster wall is a plastic expandable type.
Things You'll Need
- Electric drill
- Masonry drill bit
- Wall anchor
Check the location for the screws twice to ensure that unnecessary holes are not drilled in the wall.
Install a masonry drill bit into the chuck at the end of the drill and tighten it. Some drill chucks tighten with the use of a key and some tighten by hand. Hold the drill bit and one of the anchors end-to-end to ensure they are the same size before installing the bit into the drill.
Hold the trigger part of the drill in your dominant hand and place your other hand under the front of the drill just behind the chuck. Hold the bit at a 90-degree angle to the wall. Squeeze the trigger and guide the bit into the wall to a depth equal to the length of the wall anchor. Back out the bit while the drill is still running to avoid chipping the inside of the hole.
Insert the wall anchor into the hole and gently tap it with a hammer to make it flush to the wall. Insert the screws through the item or bracket for the item and into the wall anchor. Do not over-drive the screws into the anchors or you may strip out the anchors.
