Before you start repairing any cracks or holes, you must first check if the paint used on it is lead-based. Why? For one thing, lead is a harmful neurotoxin that can cause many health issues. As you carry out repairs, you will need to perform steps that may cause the chemical to spread into the atmosphere. It puts you and your loved ones at risk.
If your wall was painted before 1978, the paint likely contains lead.
Thankfully, all you need to do to check the presence of lead is to use lead paint test kits. You’re also better off buying them in bulk, especially if the extent of the damage is huge.
Either way, children or pregnant women should steer clear from the work area before you get started.

Mistakes to Avoid
Now that you know the steps to repair plaster walls, it’s time to get familiar with the common mistakes you need to avoid. After all, every human being tends to get careless when he or she gets too comfortable with a process. If you can avoid committing the mistakes described below, you’ll be able to repair them like a true professional.
Mistake #1: Painting over it even before it’s completely cured
Plaster takes longer to dry and cure, unlike most materials. As a general rule of thumb, you need to wait several days for the material to cure before you paint over it. Paint it too soon, and the moisture in the material will cause the paint product to bubble or bleed. This can result in a messy paint job.
Mistake #2: Skipping the patching process
Some homeowners (and surprisingly a few professionals) conflate filling with patching. They’re not in any way similar. As a result, many tend to skip the patching process. They think that filling the breaks is enough to do the job.
That’s a big no, especially for big and extensive cracks. When you patch up plaster, you’re adding new material that will attach to the lath. Skip the patching process, and the end-product isn’t likely to last long.
Mistake #3: Not carrying out the necessary structural repairs
As already mentioned, it is a durable material. In most cases, it takes something major like structural damage to cause the material to crack. Suppose you fill or patch it up without addressing the root of the problem. In that case, you’re likely to experience the same issue repeatedly. Don’t just cover up the damage. Get to the root of the problem and fix the wall once and for all.
Mistake #4: Ignoring the lath or wiring
The thing with a weakened lath or wire mesh is that it won’t be able to hold the interior plaster together. It’s even if it appears like it’s been patched up completely. Before you patch up those cracks and holes, don’t forget to check if your lath or wiring structure has been compromised. If they’re misshapen or damaged in any form, carry out the necessary repairs to hold your patching and filling material.
Common Causes of Holes
Holes in the plaster can be just as annoying as hairline cracks. Of course, a hole is not something you can ignore. But before you carry out the necessary repairs, it bears knowing why they develop holes in them.
Nails popping out
When a nail is not hammered right in the center of a joist or stud, it tends to pop through the wall in due time. It can be incredibly tempting to pick a hammer and drive it back, but this will only damage further. Even if you drive it deep again, there’s a chance that the nail will pop out again. In this case, it’s always better to nail it through a different point so that it can be securely attached to another joist or stud.
Impact by accident
Numerous things can cause holes. Most are caused by impact from accidents, such as a door swinging too hard or someone bumping against the wall after tripping over his own feet.
Water damage
When a large amount of moisture comes in contact with the wall for too long, it can cause the material to soften or loosen. Allow that moisture to have its way for too long. It will eventually damage it, leaving holes in their wake. Expanding plaster is a good indication that the material is about to pop. Water damage often occurs because of roof leaks, causing water to run through the wall’s interior.
Termite Damage
As many of us already know, termites thrive in wooden structures. It makes your wall an ideal target for infestation. Once these critters gain access to the insides, they can do significant damage.
There are many signs to watch out for indicating that termites have invaded your walls, such as pinholes and hollow sounds. Look out for bubbling and more. You’d do well to contact pest control specialists as soon as you discover these signs.
Loose Joint Tape
Joint tape is applied to the wall to cover up seams in drywalls. Because of moisture or poor construction practices, a joint tape may loosen up and separate from the wall. It causes the one behind it to crack open.
Damage from furniture
Moving around heavy furniture inside the home’s interior can cause scuff marks. These scuff marks weaken the material, which may cause it to crack open sooner or later. To avoid such damages, always be careful when moving the furniture around in your home. Take care not to apply pressure too much when sticking them close to walls.
What is plaster?
It can provide a more durable finish than even drywall if properly mixed. In the early days, it was made by mixing lime and sand. That was mixed with cattle hair and water until it’s turned into a putty substance. You get plaster once the mixture dries up and hardens.
