Are you gearing up for a painting project but worried about those pesky wall cracks ruining your smooth finish? Wise Dublin Painting Contractors has got you covered with expert tips on how to tackle this common issue. Here's what you need to know:

For small cracks in drywall, start by using a putty knife to apply multiple coats of setting-type joint compound over the crack. Remember to let each coat dry completely before applying the next one. Once the final coat is dry, use medium-grit sandpaper to smooth out the area for a seamless finish.


If you're dealing with cracks in plaster walls, the process is a bit different. Begin by slightly enlarging the crack with a scraper, then dampen the area before filling it with a suitable plaster filler product. For larger cracks or holes, consider reinforcing the area with mesh tape or a plasterboard patch before applying the filler.


After properly filling and sanding the crack, it's time to seal it with a coat of primer sealer. This step is crucial for ensuring even porosity before painting. For surfaces prone to stains, such as friable surfaces, we recommend using a stain-blocking primer like Dulux Trade Stain Block+ for optimal results.


Once the primer is dry, you're ready to apply your finish paint coats. Remember, the key to a flawless paint job is proper preparation and sealing of the repaired crack to achieve a smooth, uniform surface.
