How to Fix Cracks in Gypsum Plaster Walls Fast

Cracks in gypsum plaster walls can be quite a headache for many homes in India, especially with the monsoon season bringing in humidity, building settlement, or poor workmanship. But there’s no need to stress! You can tackle these issues easily at home without enlisting an expert. Here’s a straightforward guide to fixing your walls in just about an hour!

Step 1: Identify the Issue 

First, check whether the cracks are hairline (fine, thin lines) or wider (about the size of your finger). Hairline fractures usually occur due to shrinkage, while wider cracks often stem from structural changes. Gently press around the edges—if the plaster feels loose, it’s time to scrape it away using a putty knife.

Step 2: Clean the Area  

Widen the crack slightly into a V-shape with a scraper or an old screwdriver. Make sure to brush away all dust and debris using a dry brush or a vacuum. Follow this up by wiping the area with a damp cloth and letting it dry completely; this will help the filler stick properly.

Step 3: Apply the Filler  

Mix up a gypsum-based crack filler or a joint compound (the setting-type is best, as it dries quickly). For smaller cracks, apply a thin layer using your putty knife, pressing firmly. For larger cracks, be sure to first embed fibreglass mesh tape to add strength before applying the filler.

Step 4: Layer and Sand It Down  

Allow the first coat to dry for about 15-30 minutes. After it’s set, you can apply 2-3 additional thin layers, making sure to feather the edges to blend them into the existing wall. Once the last coat is completely dry, sand it smooth with 120-grit sandpaper to eliminate any lumps.

Step 5: Prime and Paint  

Once you’re satisfied with the smoothness, prime the patched area, and then paint it to match the rest of your wall. And voilà! Your walls are now looking as good as new!
