Install Wall Shelves to Lath and Plaster

When it comes to installing wall shelves on old houses with lath and plaster walls, there are some unique challenges that come into play. These types of walls were built using a combination of wooden laths (strips) and a mixture of lime-based mortar and animal hair, which can be prone to crumbling and flaking off.

For those who have dealt with this type of wall, it's no surprise that fixing anything to the wall often requires carving out larger holes and then filling them in. And when you finally manage to get your fixings in place, there's a good chance they'll come loose over time due to the fragile nature of the plaster.

However, if you're determined to install wall shelves on lath and plaster walls, there are some techniques and tools that can help make the process easier and more secure. One option is to use molly bolts, which are designed specifically for hanging heavy objects on hollow walls like these.

To start, you'll need to identify where your studs are located behind the plaster. This might require using a stud finder or knocking gently on the wall to locate the areas that sound solid. Once you've found your studs, you can use them as anchors for your shelves.

If there aren't any studs available, or if you're looking for a more secure option, molly bolts are the way to go. These clever little devices have a screw-like shaft that expands when tightened, providing a sturdy anchor in the wall. To install one, simply drill a small hole in the wall and insert the bolt, then turn it clockwise until it's fully seated.

Another option is to use hollow wall anchors, which are designed specifically for hanging heavy objects on plaster walls without finding a stud. These anchors have a spring-loaded mechanism that expands when inserted into the wall, providing a secure hold for your shelves.

In addition to using specialized fasteners like molly bolts and hollow wall anchors, there are some general tips you can follow to ensure your wall shelves are securely installed. For one, make sure to use a level to draw a straight line on the wall where you want your shelves to go. This will help you ensure that they're properly aligned and won't be crooked.

Another important step is to pre-drill holes in the wall for your fasteners, rather than trying to force them into place without drilling first. This can help prevent damage to the plaster and reduce the risk of it crumbling or cracking.

By following these tips and using the right tools and materials, you should be able to install your wall shelves securely on lath and plaster walls. Just remember to take your time, be patient, and don't be afraid to get creative with your installation technique!
