Plasterboard walls (also known as drywall) are quite common in many homes, especially in modern builds. They’re lightweight, easy to install, and versatile for different types of construction. But when it comes to repairs, many people make mistakes that end up costing more time and money. Whether you’re fixing cracks, holes, or dents, avoiding common errors is key to getting a smooth, professional-looking result.
Let’s get into some of the most common plasterboard wall repair mistakes to avoid
Not cleaning the area properly
One of the biggest mistakes people make is not properly preparing the area before beginning the plasterboard wall repair. If there’s dust, debris, or any loose plaster, it can prevent the patch or filler from sticking properly. Before you start any repair, take the time to clean the damaged area. Use a damp cloth to remove dust and dirt, and make sure any loose pieces of plasterboard are removed.
Using the wrong tools or materials
Another common issue is using the wrong tools or materials for the job. Plasterboard wall repair needs specific products, like plaster, joint compound, or a proper plasterboard patch. Sometimes people think they can just use any old filler or even glue to fix holes or cracks, but this often leads to poor results.
Make sure to use the right tools when attempting plasterboard wall repair, like a putty knife for applying filler, a utility knife to cut clean edges around the damage, and sandpaper to smooth the area afterward. Investing in good-quality materials can make a huge difference in the finish.
Not using enough support for larger holes
When repairing small dents or cracks, a simple filler will usually do the trick. However, for larger holes in the plasterboard, you need to provide proper support. Some people skip this step and simply fill in the hole with plaster or joint compound, but without support, the patch won’t last.
For larger holes, you should use a plasterboard patch or create your own by cutting a piece of plasterboard to fit the hole. Secure the patch with screws or adhesive before applying any filler. This gives the repair a solid backing and prevents it from caving in over time.
Rushing the job
Many people get frustrated with plasterboard wall repair because they rush the process, especially when it comes to drying times. If you don’t let the filler or joint compound dry completely between coats, it will likely crack, shrink, or look uneven. Patience is key!
Each layer of filler or plaster needs to dry thoroughly before sanding and applying the next coat. Depending on the product you use, drying time can vary, so check the instructions on the packaging. Rushing the job may save time upfront, but it will likely lead to more repairs down the road.
Not sanding properly
A smooth finish is the goal of any plasterboard wall repair, but many people fail to sand the area properly after applying the filler. Skipping the sanding step or not using fine enough sandpaper can leave the repaired area looking lumpy or uneven.
Once your filler or plaster has dried, use fine-grit sandpaper (around 120-180 grit) to smooth the area. Be gentle, though – sanding too hard can damage the surrounding plasterboard. After sanding, wipe the area with a damp cloth to remove any dust before painting.
Mismatching paint
One of the final steps in a plasterboard wall repair is painting over the patched area. A common mistake here is mismatching the paint. It’s not just about getting the right colour – the finish matters too. If the repaired area has a different finish (like matte vs. glossy) or texture than the surrounding wall, the patch will stand out.
When painting over a plasterboard wall repair, make sure to use the same type of paint and finish that’s already on the wall. It’s often a good idea to paint the entire wall rather than just the patch, as this will help everything blend seamlessly.
Ignoring small cracks
Sometimes people ignore small cracks or dents in their plasterboard, thinking they won’t cause any problems. But even minor damage can get worse over time. Small cracks can spread, especially in areas where there’s movement or temperature changes, like near doors or windows.
It’s best to repair small cracks as soon as you notice them. Filling them with plaster or joint compound early on can prevent larger issues down the road.
Overfilling the hole
Another common mistake is overfilling the hole or crack with too much filler or plaster. This often happens when people try to fix the damage in one go. The result is a bulky, uneven patch that’s hard to smooth out later.
Instead, apply the filler in thin layers, letting each layer dry before adding more. This approach gives you a smoother, more professional finish and prevents cracking or shrinking.
Failing to prime before painting
A mistake often overlooked is skipping the priming step before painting over the repaired area. Plaster or filler absorbs paint differently than the surrounding wall, which can lead to a patchy or uneven finish. Applying a primer before painting makes sure that the paint adheres evenly and blends with the rest of the wall.
Not calling a professional when needed
While DIY plasterboard wall repair can save you money, sometimes it’s best to call in a professional, especially if the damage is extensive or you’re unsure of your skills. Trying to fix a large crack or a damaged ceiling on your own can end up causing more harm than good, leading to costly repairs later. Know when to leave the plasterboard wall repair for the pros.
