How Do You Repair Hairline Cracks In Drywall?
Even imperceptible shifting of a house foundation may result in small hairline cracks in the drywall. The most common areas for cracks are above the corners of doors, above and below installed windows and in the corners of a room, near the ceiling. When cracks occur, you can repair them by applying drywall mud, letting it dry and then sanding the area before repainting. The use of mesh drywall tape may help the area resist further cracking. Prepare the area by removing nearby wall hangings and by draping the floor with a heavy tarp to prevent damage to the carpet or the flooring. Stir the premixed drywall mud to smooth out any thickened areas, and scoop out a small amount into your drywall tray. A drywall tray is narrow and oblong to hold the mud while providing a smooth edge on which to scrape excess mud from your trowel. Apply a scoop of drywall mud to the hairline crack with the 6-inch taping knife, smoothing the mud into the crack by using pressure as you run the knife from the top
