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.

Yes, you can install drywall over plaster, but there are important factors to consider. While it can create a smooth, flat surface, it is often not the best approach. Installing drywall over plaster will increase the wall's thickness, which can cause issues with existing window and door frames that may no longer fit. You might also need to adjust power outlets to keep them accessible. A better, though more expensive, option is to remove the old plaster and lath entirely before installing new drywall. Drywalling directly over plaster seals in the old material, and if any problems arise later, you will need to remove both layers down to the structural beams for repairs. Given the potential complications, this job is best handled by professionals.

If the holes in the plaster are small, you can fill them with layers of patching plaster until they’re filled. After it dries, you can sand the plaster and paint over it. If the hole is much larger, consider using bonding plaster first and then a layer of patching plaster, completing the process with sanding and a layer of paint.

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.
