Plaster walls do not present a challenge to drill them; however the cast gets more stamina and can then break once you penetrate the surface leading to more pain head in the drilling process. You have to be more careful when drilling drywall to prevent damage or drilling in the wrong place.

A device metal detector can work well on a wall with plaster, but does not determine the location of studs behind drywall. You may be able to get close to the location of the studs in the wall using a search engine for metal to penetrate deeper into a wall. Once you find a post, you can estimate that the others are about 16 inches (40.64 cm) apart from each other. If you’re still unsure about the exact location of the studs, drill pilot holes in the wall with a small bit of mason. If you feel the drill bit touches an air pocket behind the plaster, this indicates no posts. If you encounter resistance, no matter how perforates inside the wall, you penetrate into a pole.

Perforated technique

When drilling plaster, you cannot use excessive force because otherwise you run the risk of forming cracks in the plaster and the plaster crumbling. This means that if the drill has a hammer action, it must not be used, although the plaster may not resist at first drilling. You must drill slowly at first, because the plaster is slippery on the surface and the drill can jump through the wall, entering a wrong point.

Masking tape

Old plaster wall may collapse or break when penetrate it with a nail or a drill, unlike the new walls. The outer surface of the drywall is where it starts to crumble, as it is broken by the force of penetration. To combat the tendency of the plaster to crack and crumble, place a piece of masking tape in place where you want to punch the wall. The tape keeps the cast in place, instead of leaving it to break apart and crumble. When you have finished drilling remove the painter’s tape on the wall without fear of the paint off.

Enlarge the hole

You can widen the hole you drill in a plaster wall if you need one wider to fit a stand. Sometimes the biggest drill you have available is a smaller one than the cavity wall support you need to use an object hanging on the wall. In such situation, you must insert a long, thin instrument that fits inside, like a knife or a screwdriver. Use the tool to the largest with a circular as press against the sides of the whole movement.
