- Patch and Repair: After removing the plaster, the plasterboard will likely need patching. Use plasterboard tape and joint compound to cover any seams or holes. Sand the area smooth once the compound is dry.
- Dust Reduction: Keep the area as dust-free as possible by using a shop vac equipped with a fine dust bag while you work. This not only maintains a clean workspace but also reduces the amount of cleanup afterward.
- Proper Disposal: Place removed plaster into heavy-duty contractor bags as you work to keep your area tidy. Ensure that the bags are not too heavy to lift and that you dispose of the material according to local regulations.
- Safety Precautions: Always wear a dust mask or respirator, as well as safety goggles, when working with plaster to protect your lungs and eyes from fine particles.
- Consider Professional Help: If the plaster is on ceilings or in large, difficult-to-reach areas, consider hiring a professional to avoid potential injury or damage.
By following these tips, you can more effectively remove plaster from plasterboard walls. Keep in mind that if the plasterboard is significantly damaged during the process, it may be more efficient to remove the entire panel and replace it with a new one, especially if you’re considering the cost of replacing plaster with drywall as an alternative.

Removing Plaster and Lath: Techniques and Precautions
Removing plaster and lath is a more complex process compared to removing plaster alone. Here are some techniques and precautions on how to remove lath and plaster walls to consider:
