Drywall Insulation FAQs, answered by experts

Plaster ceilings can sag for several reasons. In some cases, the plaster and other building materials shift and come apart over time, which is why you’ll commonly find drooping plaster ceilings in older homes. Improper installation, foot traffic, and water damage—often from a leaky roof or a broken pipe—can also cause plaster ceilings to sag.

Drywall can be toxic to the environment and to humans in some cases. As drywall breaks down in a landfill and comes in contact with other organic chemicals, it can create hydrogen sulfide gas or leach into the groundwater. Additionally, the CDC recommends methods for controlling the inhalation of drywall dust when handled. While the common ingredients of drywall—gypsum, silica, and mica—are naturally occurring, they can cause irritation in some humans.

You can put certain types of plaster over other types, but doing so isn't always the best idea. For example, putting a coat of gypsum over lime plaster is possible, but doing so will limit the lime plaster's breathability and potentially affect its performance.

Since cement plaster tends to leave a textured surface, no matter how much you smooth it, some people prefer to use gypsum plaster as a topcoat over cement plaster, creating a smoother surface.

Whether to repair or replace water-damaged plaster depends on the scale of the damage. For small, limited areas, you can often perform a repair yourself. If you choose to paint over small patches, ensure the surface is completely dry and apply a coat of antifungal primer first to prevent mold growth. However, simply painting or plastering over the damage is only a temporary solution that doesn't address the core problem. For more extensive or long-term damage, the plaster may be compromised, and there is a risk of mold. In these cases, it is recommended to remove the damaged section of plasterboard and replace it. You may consider hiring a professional for the repair, and it's worth noting that water damage is often covered by home insurance.

Yes, drywall nail pops are a common occurrence in homes, both new and old, resulting from the settling and shifting of the structure over time. Though not present in every room or on every wall, encountering nail pops in different sections of a home is not unusual, particularly if the temperature, humidity, or foundation has experienced changes.
