Common causes of ceiling cracks along drywall seams include poor drywall installation techniques, structural issues, truss uplift, and foundation problems. Temperature and humidity also play major roles in ceiling cracks flush with the wall. As the drywall shrinks and expands from major temperature changes or extreme humidity shifts, this can cause the drywall to crack.

All plaster walls will crack over time due to normal house settling and expansion and contraction from temperature and moisture changes. Small, thin hairline cracks are generally not serious and are mostly a cosmetic issue. However, larger or more significant cracks can indicate structural problems.

Here's how to tell the difference:

• Cosmetic Cracks: Cracks that are 0.5 cm (0.2 inches) or thinner are typically cosmetic.

• Structural Cracks: Cracks wider than 0.5 cm, excessive or deep cracks, multiple cracks in the same area, or cracks that span around corners can signify a structural or foundation issue. Cracks along the joints where walls meet the ceiling also warrant attention.

For cracks wider than 0.5 cm, structural repair is needed. If a crack is 2.5 cm (1 inch) or wider, or if you notice any signs of a structural problem, it is best to contact a plaster repair professional to assess the damage.

Plastering and skimming are two different techniques for finishing walls. Plastering involves applying a thick layer of a plaster mixture—typically containing gypsum, lime, cement, sand, and water—to create a new surface. This process often requires multiple coats and is used for repairing significant damage or creating decorative textures. Skimming, on the other hand, is a technique that involves applying a thin layer of drywall compound or joint compound over an existing surface to smooth it out, covering minor imperfections, small cracks, or uneven textures for a polished look. Plastering is generally more costly and labor-intensive than skimming. Although some people use the terms interchangeably, they refer to different processes and materials.

Plaster can be a difficult DIY to master, especially if you plan to plaster an entire room, rather than patch a small area. Before you begin a plaster DIY project, you need to know which tools and type of plaster to use. It's also important to know how to prepare the surface and apply the plaster for a smooth finish. If that all sounds like a lot of work, you may prefer hiring a local plaster repair contractor to do the job.
