Step 1: Prepare the Area
1. Cut Out the Damaged Area
Start by examining the crack and the plaster around it. Use a sharp utility knife to cut out the damaged plaster around the crack, making a V-shaped groove centred on the crack.
This step removes any loose paint or plaster and gives you a clean area to work with.
2. Score the Crack
Next, gently score the edges of the crack with the utility knife. This helps to remove any remaining loose plaster and prepares the crack for filling, ensuring the new plaster will stick properly.
Step 2: Fill the Crack
1. Apply Jointing Tape
Place jointing tape over the crack. This tape provides extra support and helps make sure the repair is smooth and even.
It also helps prevent the crack from coming back.
2. Fill with Joint Compound
Using a broad scraper, fill the crack with plaster compound. Make sure the compound is level with the surrounding plaster.
This first layer forms the base for the next coats of plaster.
3. Apply Additional Coats
Once the first coat is dry, apply more thin coats of plaster compound. Feather the edges of each coat so they blend smoothly with the wall.
Let each coat dry completely before adding the next one. This layering process ensures a smooth and professional-looking finish.
Step 3: Sand and Finish
1. Sand the Area
After the final coat of plaster compound is dry, use fine-grit sandpaper to sand the area. This makes the surface smooth and even with the rest of the wall, preparing it for painting.
2. Prime and Paint
Once sanding is done, apply a suitable primer to the area. Priming seals the plaster and creates a uniform surface for painting.
After the primer dries, paint over the area with matching wall paint to complete the repair. This final step of repairs blends seamlessly with the rest of the wall.
Extra Tips for a Great Repair
Use the Right Filler
Choosing the right filler is crucial for a durable repair. Products like Gyproc Easi-Fill 20 are excellent for plaster walls because they are easy to use and give great results.
Work in Small Sections
When applying the plaster compound, work in small sections. This helps you maintain even coverage and avoid creating air pockets, which can cause problems later.
Let Each Coat Dry Completely
Patience is key. Make sure each coat of plaster compound is fully dry before you apply the next one.
This prevents the filler from absorbing moisture too quickly, which can cause it to crack or shrink.
Avoid Over-Sanding
While sanding is important, don’t overdo it. Over-sanding can create dips in the plaster.
Use light, even strokes and check the smoothness frequently to get the best results.
Use Consistent Pressure
When applying the plaster compound, maintain consistent pressure with the scraper. This helps you apply the plaster evenly and avoid uneven thickness.
