Nov 11, 2024
Cracks in walls develop due to the expansion and contraction caused by structural settling, temperature fluctuations, and changes in moisture levels. They are common but also alarming if not treated timely. It can lead to water infiltration, which weakens the foundation and degrades the aesthetics of your home.
Crack filler is just the right solution to address these complexities, safeguarding your home’s structural integrity and maintaining its visual appearance. This blog explores several effective methods for applying crack filler, ensuring long-lasting wall crack repair and preventing further damage.
Tips to Use Crack Filler Powder to Fill Cracks in Walls
- Always clean the cracked area before paste application: Use a wire brush or scraper to remove loose debris, paint or contaminants. A clean, stable surface allows the crack filler powders’ paste to adhere properly, ensuring a lasting repair.
- Use the right tools to apply crack filler: A putty knife or similar tool is advised to apply crack filler into cracks. And, for cracks in corners, a straight batten or long, flat piece of timber.
- Use a bonding agent or primer: It enhances adhesion between the existing wall and the crack filler, especially for larger cracks. It helps the filler to bond effectively, preventing the risk of future cracking.
- Be very gentle and precise with larger holes: Apply the crack filler paste in a criss-cross pattern to fill larger holes. For wider cracks, create a v-shaped groove along the crack, it provides a better grip. Push the filler firmly and spread it evenly, smoothing off the edges in a featuring motion.
If you find the task overwhelming, seeking professional assistance is the best router, to ensure a durable one-time repair.
- Always finish with sanding and painting: Polish the repaired areas with fine sandpaper once the crack filler dries. This step helps create a smooth surface that blends right with the surrounding wall. Follow up with a wall paint coat or wallpaper for a better look.
