Repairing a cracked ceiling

Job description:

Ceilings, like walls, tend over time to crack and the paint to flake. Before repainting them, you need to put them back in good condition.

Skill level: 1 – Beginner

Materials required:

  • Spatula
  • Roller
  • Filler
  • Spatula

Step by step guide to repairing a cracked ceiling:

1. With a knife, scrape all the loose paint.

2. With a brush, moisten the cracks so that the filler adheres well.

3. Then apply a first layer of filler with a knife to fill the gaps. The aim is to obtain a perfectly smooth surface. Spread the filler in the direction of the crack by pressing well.

4. Immediately remove excess and then let dry.

5. When the first layer is hard, no more trace of moisture (depending on the thickness of the coating it just take time, at least 24 hours) put a second layer. Let it dry again.

6. When the layer is dry, use fine paper or very fine grit sandpaper and sand until the surface is perfectly smooth and flat.

7. You can then start painting the ceiling with a roller to obtain a clean and uniform result.

Caution: If the cracks are located near openings, lintels above and below joists, they may be due to an error in design or construction. In this case, filling would mask the problem but not eliminate it, with sometimes serious consequences, such as the collapse of a ceiling. In this case, get in touch soon with a specialist.

If you are unsure about the job, you might want to contact a local painter and decorator.
