A Complete Guide to Fixing Cracks Between Wall and Ceiling

It’s critical that you act now to fix any wall-ceiling cracks you’ve observed before they get worse. We’ll walk you through the process of fixing the crack and stopping it from happening again in this article.

How can I determine if a ceiling crack is serious?

The location, size, and kind of a ceiling crack will determine how dangerous it is. To help you make a more informed decision—or just to ease your mind—we listed the various kinds of ceiling cracks in order of severity:

minute fissures.

Thin cosmetic cracks known as hairline cracks are brought on by changes in humidity or temperature. These variations may cause the plaster to expand or contract, resulting in tiny cracks. Simply said, hairline cracks are unsightly and are readily repaired with a fresh coat of paint.

Old paint coats may also cause tiny fractures to show up on the walls and ceilings. Cracks may show up on walls or ceilings that have had several coats of paint applied. Make sure to remove any previous paint before applying a fresh coat if you wish to remedy hairline cracks that were filled in by previous paint.

clean cracks.

Straight cracks frequently trace the joint’s edge along the drywall tape. The most frequent cause of these is incompetent application of drywall tape, which occurs when inadequate plaster is applied and drywall tape cannot properly attach to the joints.

cracked surfaces that are discolored.

Water damage can be indicated by discolored fissures, such as brown and yellow ones. Water damage can result in more serious issues, even though it is not related to structural damage. To locate and fix the source of the water leak, we advise getting in touch with a licensed London plumber.

A spiderweb breaks.

Similar to a spider web, spiderweb cracks have a central point from which they radiate outward. Larger spiderweb cracks may be caused by foundation settlement, which may be connected to impaired structural integrity. Small spiderweb cracks are typically not dangerous and are frequently the result of poor workmanship.

fissures separating the wall and ceiling.

Truss uplift could be the reason for cracks that show up between the wall and ceiling. Because of changes in humidity or temperature, roof trusses often move somewhat. On the other hand, cracks that extend from the ceiling to the wall indicate structural damage and need to be repaired right once.

large, profound fissures.

Serious concerns arise from large, deep fissures. If you have sagging ceilings and big, deep fractures in them, you have serious structural damage that needs to be fixed right once to prevent the ceiling from collapsing.

How to Repair a Crack in the Ceiling and Wall:

Fixing wall-to-ceiling cracks requires a basic understanding of drywall repair. To repair the crack, take these actions:

Step 1: Get ready

You must prepare the region before beginning the repair process. Using a putty knife, first clean the fracture and remove any dirt. Next, to stop the joint compound from spreading, conceal the area surrounding the crack with painter’s tape.

Step 2: Patching the Holes

Using a putty knife, fill the crack with joint compound. Be sure to coat the crack with a thick layer of joint compound, allowing it to spread out over the wall and ceiling. Follow the manufacturer’s instructions and let the joint compound dry.

Step 3: Surface Sanding

After the joint compound dries, smooth the surface using sandpaper. To get rid of any bumps, use coarse sandpaper first, and then move on to finer grit for a smooth finish.

Painting the Ceiling and Walls in Step Four

Painting the wall and ceiling comes last after sanding. For a smooth finish, apply the same paint as the surrounding area. Paint should be applied thinly, letting each layer dry completely before adding the next.
