Some common issues that can occur with historic plaster walls in a Federal Colonial house include:
1. Cracks: Plaster walls are prone to developing cracks over time due to the natural settling of the house. These cracks can be minor hairline cracks or larger, more serious cracks that may need professional attention.
2. Bulges: Sometimes, the plaster may bulge outwards, creating a wavy or uneven surface on the wall. This can happen due to moisture damage or the failure of underlying lath support.
3. Deterioration: Plaster can deteriorate over time due to moisture infiltration, age, or improper repairs. As a result, patches of the plaster may start to crumble or flake, requiring restoration work.
4. Water damage: Water leaks, either from the roof, plumbing, or exterior walls, can seep into the plaster walls, causing staining, softening, or crumbling. Water damage can also lead to the growth of mold or mildew on the plaster.
5. Lath failure: Traditional plaster walls are typically applied over a lath framework, and if the lath deteriorates or becomes loose, it can cause the plaster to crack or detach from the wall.
6. Paint or wallpaper adhesion problems: Historic plaster walls can be challenging for paint or wallpaper to adhere to properly, especially if the surface is uneven, rough, or flaking. This can result in peeling or bubbling of paint or wallpaper.
7. Lack of insulation: Older plaster walls often have minimal insulation, leading to poor temperature regulation and energy inefficiency. Additionally, the absence of vapor barriers in older construction can cause condensation issues and lead to damage.
8. Hanging heavy objects: Due to the unique construction and delicate nature of plaster walls, attaching heavy objects, such as shelves or artwork, can be challenging. The weight and stress may cause the plaster to crack, crumble, or even detach from the wall.
It's important to consult with professionals experienced in dealing with historic plaster walls if any of these issues arise, as improper repairs can cause further damage.
