When a cracked wall isn’t too extensive you can consider these tips. First, you’ll use a stiff putty knife to scrape the wall around the crack in order to get rid of any small pieces of plaster that may fall off or peeling paint. Then use the sharp point of the knife to cut into a crack. Use a caulk gun to apply caulk into the crack and smooth it to remove excess caulk. Be sure to let it dry and make sure the caulk is paintable. Next, cut a piece of fiberglass mesh tape and have it be a bit longer than the crack. Place it over the crack. Use a six-inch flexible joint knife, drywall blade or putty knife to apply joint compound over the tape and a few inches beyond it. Smooth it out and remove excess joint compound and let it dry; it should turn to a lighter gray color. Grab a face mask as the dust can be very fine for the next step involves sanding. Use a sanding sponge or a medium grit sandpaper to lightly sand over the area. Apply a second coat of joint compound aka mud. Let it dry as well, sand it and wipe a wet cloth or sponge to remove the resulting dust. Next, you’ll prime the area and finally paint it.
