To minimize mess and damage, it is advisable to lay down a drop cloth or plastic sheet to protect the floor or furniture in the vicinity. Additionally, you may want to wear protective goggles and a dust mask to shield your eyes and respiratory system from the generated dust.
• Start with a Pilot Hole: To prevent the plaster from cracking or chipping, it is recommended to start with a pilot hole. A pilot hole is a small hole drilled before the final hole size to guide the drill and reduce the chance of damaging the plaster. Use a drill bit slightly smaller than the desired hole size and drill slowly and steadily into the wall until the pilot hole is complete.
• Drill at the Correct Speed and Angle: When drilling into plaster, it is essential to use the correct drilling speed and angle. Applying too much pressure or drilling too quickly can cause the plaster to crack or crumble. It is best to start at a slow speed and gradually increase if necessary. Additionally, ensure that the drill is held at a perpendicular angle to the wall to create a straight hole.
• Clean up Debris: After drilling, be sure to clean up any debris left behind. This includes dust and small pieces of plaster that may have loosened during the drilling process. Use a vacuum or a damp cloth to remove the dust and maintain a clean working environment.

By following these precautions, you can minimize the risk of damaging the plaster and ensure a successful drilling experience. Remember, if you are unsure or uncomfortable drilling into plaster walls, it is always best to consult a professional.

Molly bolts consist of a metal sleeve that expands behind the wall when the screw is inserted, providing a secure anchor point. These bolts are ideal for hanging heavy objects, such as shelves or mirrors, on plaster walls. Before installing a molly bolt, it is important to pre-drill a hole in the plaster to prevent cracking. Once the hole is drilled, the molly bolt can be inserted and tightened until the metal sleeve expands, ensuring a tight fit.

Another option for hanging objects on plaster walls is the plastic anchor screw. These screws are designed to be used with plastic anchors, which are inserted into pre-drilled holes in the plaster. The anchor expands behind the wall as the screw is tightened, creating a secure hold. Plastic anchor screws are a good choice for lighter items, such as picture frames or lightweight shelves. When using plastic anchor screws, it is important to choose the appropriate size of anchor for the weight of the object you are hanging.

In addition to molly bolts and plastic anchor screws, there are also specialized screws available for plaster walls. These screws are typically self-drilling, which means that they can be inserted directly into the plaster without the need for pre-drilling. They often feature a wider thread design, which provides extra grip and prevents the screw from being pulled out of the wall. These screws are a convenient option for hanging objects on plaster walls, as they eliminate the need for additional tools or hardware.

When using screws on plaster walls, it is important to take some precautions to prevent damage to the wall. It is advisable to locate the studs behind the plaster to provide added support for heavy objects. Using a stud finder can help in finding the ideal spot for screw placement. Additionally, it is important to avoid overtightening the screws, as this can cause the plaster to crack. Tightening the screws just enough to secure the object is sufficient.

In conclusion, when hanging objects on plaster walls, using the appropriate type of screws is crucial for a secure and long-lasting installation. Molly bolts are ideal for hanging heavy items, while plastic anchor screws are suitable for lighter objects. Specialized screws that are designed for plaster walls can also be used for added convenience. Precautions should be taken to prevent damage, such as locating studs and avoiding overtightening.
