How To Fix A Crack In Drywall Ceiling?

Ceilings are frequently ignored surfaces in our houses until a crack occurs, interrupting the smooth expanse and requiring repair. Dealing with a break in a drywall ceiling may appear to be a complex operation, but with the correct equipment, materials, and a little know-how, it’s a repair that can be done effectively. 

In this article, we’ll walk you through diagnosing different sorts of cracks, understanding their causes, and providing practical strategies to repair them in this detailed guide.

How To Fix A Crack In Drywall Ceiling?

Cracks in a drywall ceiling can be unsightly and, if left untreated, lead to more severe issues. Fortunately, mending a break in a drywall ceiling is a simple procedure that sometimes requires a professional. With the correct equipment, materials, and techniques, you can repair a crack and restore the beauty of the ceiling. Here’s a detailed step-by-step tutorial to help you get started.

1. Think About Your Tools

  • Protective sheets/drop cloths 
  • A platform or ladder unit 
  • Goggles and a dust mask 
  • A flexible putty knife of good quality 
  • Mesh or fiberglass repair tape can be used for more significant cracks. 
  • Easy sand, joint compound, or ready-mixed filler 
  • Brush or vacuum 
  • sanding paper 
  • Cloth

2. Safeguard The Area

Wear protective equipment, such as a face mask and goggles, when dealing with ancient plaster. Cover the walls and furniture with plastic. Lay down drop cloths so dust or scrapings can be readily cleaned later.

3. Use A Joint Compound Or A Filler 

Making a crack slightly wider is the greatest thing to do with any damage. This ensures you get enough simple sand into the fracture to create a strong fill. After that, brush or sand away any debris before applying joint compound or filler.

Apply joint compound or filler to the crack with a putty knife and move it along the length of the gouge. To remove any surplus, wet the knife blade and scrape it from the center to the edge.

Let your putty knife clean and free of excess joint compound. This will prevent streaks in the filler when applied.

If the ceiling fracture is large, consider placing mesh or fiberglass repair tape over the crack. Then, apply the joint compound to the video and smooth it out.

4. Sand And Dry The Area

Apply multiple small joint compounds or filler applications to achieve the best blending effects. After it has cured, sand the surface to make it flat and smooth. 

You can sand this by hand or with an electric sander to make the job faster. When you’re done, get off the ladder and stand back to ensure the roof is level.

5. Complete And Clean Up 

Clean the area you’ve filled with the nozzle of your vacuum, then wipe it off with a cloth. Because there will be a lot of dust particles around, clean up the entire area before you start painting.

What Causes Ceiling Cracks?

1. Above-Ground Damage

Ceilings aren’t just the part that usually faces the room. Ceilings, too, have a top side. The ceiling in the attic usually is unprotected. With only loose-fill or fiberglass insulation over the drywall, the drywall is vulnerable to harm from anyone moving around or dropping anything heavy.

2. Inadequate Taping Joints

Long, straight cracks that run parallel to the joists are frequently caused by inadequately taped drywall seams. The tape may have been appropriately applied after being topped with more joint compounds.

3. Water Invasion

Water may flow down through the drywall ceiling from the roof, flashing, or vents. Water damage can appear as yellow or brown streaks or bubbled paint. Water can flow into the gaps between drywall panels and loosen the joint tape, causing cracks to form.

4. Structural Deterioration

While foundation settling is normal, structural damage is not. The basement joists, beams, foundation wall, band joist, and sill plate can all cause structural damage to a property. As damage progresses upward, it can affect windows and entrances, walls, and finally, the ceiling.

What Can I Use To Repair Ceiling Cracks?

Use a plaster sealer to seal new, bare, and porous surfaces. Before applying, fix any cracks more significant than the hairline using Polyfilla. Use a short pile (up to 5mm, 3/16) for the most outstanding results on smooth ceilings.

Is It Simple To Repair Ceiling Cracks?

While fixing cracks in walls is relatively simple, patching cracks in ceilings, which often have some form of texture applied and are overhead, is a (literal) pain in the neck.

Should You Mud Or Caulk Drywall Cracks?

If the crack occurs on a flat surface, fill it with spackle or joint compound, which is available pre-mixed at your local hardware shop. Spackle and joint compound can also be used to fill cracks around the edge of a wall or in an exterior corner. Even at strange angles, it will hold and dry. If damages occur where the ceiling meets the wall, fill them with caulk.

How Can You Tell If A Fracture In The Ceiling Is Structural?

The size, direction, location, and color of a ceiling crack can provide you with much information about how severe your ceiling cracks are. In general, cracks larger than 1/16 inch in width indicate structural problems.

Repairing a drywall ceiling crack is critical not only for cosmetic reasons but also for structural stability. You may efficiently fix the fracture and avoid further damage by following the procedures in the repair process. Cleaning, filling, and sanding the crack correctly gives a smooth finish. The job is finished by applying primer and paint, leaving the ceiling immaculate.
