Wall repair: a step by step guide to fixing cracks and dents
Cracks and dents can appear in your walls as weather conditions change throughout the year. They form when the temperature goes up and down too quickly. And they’re ugly. They bring down how your home looks. Worse, they bring down how your home feels. They make day-to-day living uncomfortable. If you're looking for a simple, easy wall repair guide you’ve come to the right place.
Step 1: Make the crack a little deeper
This may sound strange but it’s necessary for a wall repair solution that will last. Making the crack or dent a little deeper will let you get to the loose concrete, flaked paint, age-old filler, dust or debris trapped in the gap. Using a scraper or even a screwdriver, open the crack a little by applying pressure along the line of the crack. Using a cloth or brush, clean out the old junk inside the gap. You can even use a vacuum to suck it out. A clean opening will help the filler stick more firmly later on.
Step 2: Prepare your filler
There are many kinds of fillers on the market, some of which come pre-mixed. Others come in the form of a powder which you’ll need to mix with a liquid. How much filler you need will depend on how big the crack or hole you’re trying to cover up is. Stir the filler powder with water until you have a nice, smooth paste. With most fillers, you have about 45 minutes before it begins solidifying and is no longer workable.
Step 3: Fill the gaps
Using a filling blade push the filler into the open crack or dent. Smooth it across the gap, pressing in firmly to make sure it’s filled in properly. Be generous with the filler. Don’t worry about overflow or if it looks messy.
Step 4: Let the filler dry and sand down
Different fillers take different lengths of time to dry up. You should give the filler at least 4 hours to dry but if you want to be absolutely certain, give it half a day. As the filler dries, it may sink inwards. If it does, use a little more filler to fill in the gap. Again, let it dry out. When you’re sure the filler has dried, use some fine grade sandpaper to sand it back so it’s nice and smooth.
Step 5: Paint
This is the easy, fun part. Paint over the sanded area for a beautiful finish tp your wall repair!
I’ve fixed the cracks but now they’re back
Cracks or dents can appear at any time for a wide variety of reasons. Sometimes it’s as simple as a seasonal change. On other occasions, the reasons go deeper and wall repair may be more complicated. The source of cracks could be something more serious like a shift in your home’s foundations due to eroded soil. It may be poor construction.
