Best Way To Hang Heavy Mirror On Lath And Plaster Wall

Hanging a heavy mirror on a lath and plaster wall can be a daunting task, but with the right tools and techniques, it can be done safely and securely. Here are the essential aspects to consider to ensure a successful installation:

1. Prepare the Wall:

Start by cleaning the wall surface and removing any dirt or debris. Check the wall for any loose plaster or cracks and repair them before hanging the mirror. Use a stud finder to locate the studs behind the wall, as they will provide the most support for the mirror.

2. Choose the Right Hardware:

Depending on the weight and size of the mirror, you may need heavy-duty hanging hardware such as toggle bolts, molly bolts, or French cleats. Toggle bolts are ideal for hollow walls, while molly bolts provide a secure hold for heavier mirrors. French cleats distribute the weight evenly, making them suitable for very large mirrors.

3. Mark the Hanging Points:

Measure the distance between the hanging points on the back of the mirror and mark the corresponding points on the wall. Use a level to ensure that the mirror will hang straight. If you are unsure about the exact placement, consider using a mirror template.

4. Install the Hardware:

Follow the manufacturer's instructions for installing the hanging hardware. For toggle bolts, drill a small hole in the wall and insert the toggle into the hole. For molly bolts, drill a slightly larger hole and insert the molly bolt into the hole, expanding it as you tighten the screw. For French cleats, attach the cleats to the wall and the back of the mirror.

5. Hang the Mirror:

Lift the mirror onto the installed hardware and slide it into place, ensuring it is level. Tighten any screws or bolts securely to hold the mirror firmly against the wall. Use a mirror adhesive for added stability, especially for heavier mirrors.

Additional Tips:

- For large or very heavy mirrors, consider using more than one type of hanging hardware for maximum support.

- If the lath and plaster wall is particularly weak, reinforce it by adding a piece of plywood or drywall behind the hanging area.

- Exercise caution when working with lath and plaster walls, as they can be fragile. Avoid drilling too deeply or hammering too hard, which could damage the wall.
