Many homes still have plaster walls in prime condition, often valued by homeowners and homebuyers. They are beautiful, solid, and especially good at soundproofing rooms. But plaster walls respond to inevitable foundation shifts and climatic changes.
They can begin to crack. Everyday life, with its bumps and bangs, also takes its toll on plaster walls. And certain key areas, such as above and beside doorways and windows, are classic areas of cracking.
Nearly all homes with plaster walls will experience cracks at some point in their lifetime – but knowing how to repair them is crucial to maintaining the wall’s integrity and beauty. In this blog post, we’ll explain the causes of plaster wall cracking, the different methods for repairing cracks, and the necessary supplies you’ll need to get the job done.
Causes Of Plaster Wall Cracking.
When repairing plaster wall cracks, it’s essential to know the causes. Poorly installed plaster can be the main culprit, as can cold climates and high humidity levels. If the cracks are small, they may not require any repair. However, if the cracks are larger or the plaster is starting to break, it’s best to take action before the damage worsens.
Correcting the problem before it becomes bigger is the best action and can protect your home from further damage. So, if you notice any plaster wall cracks, don’t hesitate to contact the professionals!
How To Fix Cracks In Plaster
If your plaster walls crack, the first step is to clean the crack, and a drywall compound is applied to seal it. Once the drywall compound is applied, use a sprayer to seal the crack. Lastly, paint over any seams or cracks. If the crack is larger, a drywall compound can use to repair the wall in larger areas.
1. Equipment / Tools
When repairing plaster walls, it is important to use the correct equipment and tools. Always wear protective gear like a face mask and gloves to minimize the risk of serious injury. The most common mistake plasterers make is not using the right hammer when repairing cracks in plaster. A special plasterer’s hammer is needed as it delivers more force than other hammers of the same weight category.
Another crucial piece of equipment you will need while working on plaster walls is a spirit level, which helps in keeping your work accurate and stable during joint wall installation. Finally, keep a supply of water handy in case any liquid seeps through the crack or surface you are patching up!
2. Materials
There are a few steps in patching a crack in a plaster wall using a drywall compound. Follow the instructions closely to avoid any complications:
- Dry the area around the crack completely by sanding it if needed.
- Apply joint compound, starting from the outside and working your way in towards the crack, using a putty knife or trowel as needed.
- Use water to smooth out the compound and let it dry for at least 24 hours (preferably 48 hours).
4 . Once it’s dry, make an initial repair with plaster mix by applying it over the top of the joint compound and then hammering and chiseling until you have a solid surface. Let that coat of plaster dry again before making repairs to cracks or holes that may occur due to wear or moisture infiltration
3. Score The Crack
The crack filler method is the perfect solution if you are looking for an easy and affordable way to repair plaster cracks. This technique involves scoring the crack in plaster using a drywall tester, then filling it with a putty knife. Next, primer, paint, and finish can be applied as required. Overall, this process takes around 2 hours to complete.
4. Cut The Paper Drywall Tape
If the crack in your drywall is wide enough, you will need to cut the paper drywall tape and use a patch kit. This is usually the best repair solution in cases where the plaster crack goes at least 1/4 inch deep. However, note that not all plaster cracks are fixable using just drywall tape – only those that go at least 1/4 inch deep.
Always consult an expert for more complex repairs – such as fixing a wall in an L-shape or cornering around curves. If the plaster is loose, you can fix it by using spackle or joint compound, depending on the severity of looseness.
5. Spread The Joint Compound
Repairing plaster walls isn’t always the easiest or most cost-effective option, but a joint compound can be a great solution. Sand away any excess after 24 hours, and then repaint your plaster wall as usual. Apply a thick layer of joint compound to the crack and leave it to dry for 24 hours. If the crack is more extensive, apply two layers of joint compound and leave them to dry for 48 hours each time before painting again.
6. Tip
You can follow a few simple tips to fix plaster cracks quickly and easily. First, use a caulk to fill in the cracks – this will help seal them and prevent paint or plaster from seeping into the crack. Next, ensure your level is set before starting work – this will ensure that the plaster wall looks even when finished. Finally, clean up any excess mortar after fixing the crack – it’s important not to leave any grime or mess behind!
7. Apply Tape To The Crack
When repairing cracks in the plaster wall, using tape is the best solution. Not only will it help to stop the plaster from falling, but it can also use in both small and large cracks. If the crack is too big, you may need to use a filler such as spackle or joint compound instead of tape. To apply tape correctly, first ensure that you have prepared the area by sanding it down and removing any dust or dirt.
Then line up the edges of the crack so that they are even with each other and press them firmly against each other with your hands. Make sure there are no gaps anywhere – this will cause air bubbles to form, which could eventually lead to the plaster surface’s cracking. Once taped up, leave it for at least 24 hours before taking off, just like you would when patching drywall seams!
8. Mud Over The Tape
You need to know a few things if your plaster wall starts to crack: – First of all, make sure the cracks are small, and the plaster is still damp. This will create a temporary bond between the mud and the plaster that can be adequately re-taped. – If cracks are too wide, a full repair will need to be done.
In this case, it is best to use dry mud rather than water to stick the plaster back together better. – Finally, if the plaster is dry – in other words, if there’s no moisture left – then you can use mud to stick it back together again
9. Sand The Repair
When repairing a crack in the plaster, start by cleaning the area where the crack is with water and soap. Use a putty knife to smooth out any bumps or ridges on the surface of the plaster. Apply a coat of sand to the crack, and then use your plunger to push it into place. Finally, seal the repair with a coat of paint or an adhesive
10. Apply An Additional Mud Coat (Optional)
Anyone with the right skills and a bit of DIY know-how can fix plaster cracks. An additional mud coat will prevent moisture from seeping into the crack and causing it to widen over time. This will help to seal the crack and protect the plaster from further damage.
11. Clean The Area
The first and most important step when repairing drywall is getting into any stubborn crevices. Use a steamer to soften the wall so that plaster can easily apply. Once the patch is dry, smooth it out for an even finish.
Next, ensure the area is clean before beginning – dirt, grease, or debris will only complicate matters further. Finally, allow 24 hours for the repair to fully set before handling or moving the wall
