There are several warning signs that a ceiling crack is connected to a larger issue. For starters, if the crack is wider than 1/8 inch or longer than 12 inches, you might have a more serious problem. The same applies if you have multiple smaller cracks or cracks going across the ceiling and down the wall. In any of these situations, you should ask a professional to assess the damage.

You can technically just paint over hairline cracks in plaster since these cracks are often harmless, but this will mostly be a waste of paint. Paint will only hide the hairline crack for a few months before it shows up again. The best solution is to repair the crack with flexible filler or joint compound before repainting.

Applying plaster to a wall will usually cost between $2 and $10 per square foot for both the material and labor. The cost will vary based on the quality of the plaster you’re using and whether or not prep work is required before the work begins. Wall prep can add up to about 10% to your total costs. Plastering exterior walls can be more expensive in many cases because they are taller and require scaffolding and safety equipment.

Small hairline cracks in plaster walls are not serious and are mostly cosmetic, but larger or widespread cracks indicate structural problems that need repair. 

• Cracks 0.5 cm (0.2 inches) or thinner: Cosmetic cracks you can repair if desired.

• Cracks wider than 0.5 centimeters or widespread cracks: Structural repair is needed, either DIY or by a pro.

• Cracks 2.5 centimeters (1 inch) or wider: Contact a plaster repair professional.

Watch for large, deep cracks, multiple cracks in the same area, and cracks along the walls where they meet the ceiling. Repair these cracks to prevent further damage.
