In time, drywall can experience damage which can range from cracks to holes, but the good news is that most repairs are easy, a DIY project and inexpensive to fix. Here are ways to make the repair on the drywall, depending on the size, type and place of the damage.
Basically, drywall is made up of a seamless paper covering and when a crack appears, it is usually found on a seam where two drywall sheets meet, to which this is easily fixed. When you find a crack that is on a vertical or horizontal seam, using the corner of a paint scraper or utility knife or chisel, carefully widen the crack to determine two things: if the crack extends completely through the paper, which is covering the seam, and if the tape has pulled loose from the wall surface. If the tape is intact and well-adhered, it is most probably that the crack was caused by the old drywall compound which was drying and shrinking, at the same time; therefore, fill the crack with a new compound following these procedures: hold the knife at a 70 degree angle and swipe the new compound across the crack, then allow the joint compound to completely dry, and afterwards sand lightly the area and wipe the dust before painting over it. The following procedures are to be applied if the tape has pulled loose from the wall: use a razor knife to cut the tape about 6 to 12 inches from both ends of the damage drywall, then remove the tape being careful not to tear away the drywall’s paper covering, and scrape away any loose compound and with the razor knife widen the crack through the wall into the stud cavity.
As soon as the crack is expanded, you may now start the repair procedures, as follows: fill the crack with a new drywall compound and apply a thin coat of the compound to the wall surface where the old tape was removed and while the compound is still wet, use a strip of fiberglass tape and place it over the seam to bridge the gap between the ends of the new tape and use a putty knife to flatten the wrinkles and to merge the tape into the compound. Once the applied compound has dried up, apply again a new layer of coating over the taped area and by covering the tape, feather the edges of the new compound into the surrounding wall surface. It is vital that drywall compounds be applied in multiples of thin coating layers since thick layers are difficult to smooth out and will have a tendency to cause future cracks.Finding Similarities Between Options and Life
