Old wall finishes: what can stay?
The fact that an old layer still looks neat does not mean that it is suitable as a substrate. adhesion, pollution and build-up must be assessed.

The answer to your situation
The fact that an old layer still looks neat does not mean that it is suitable as a substrate. adhesion, pollution and build-up must be assessed.
See the finish in detail.
What should you check first?
Tell which layers are present: paint, wallpaper, decorative plaster or previous repair. Different layers can each have their own adhesion and suction. Send images of damage and loose parts. Do not make the problem invisible with a new layer before it is assessed.
How does this affect your choice?
The plasterer determines what preparation is required in the chosen system. Sometimes an existing layer can be treated; sometimes it has to be removed. A strongly sucking or polluted substrate requires a different approach than smooth concrete. One primer is therefore no solution for any wall.
Planning the next step
Record the size of removal and repair in the quotation. Describe what happens when extra bad parts become visible during work. This makes more work discussable before an entire wall is open. Then tune the new finish and connection to windows and boards.
Practical checklist
- Describe all layers
- Show loose spots
- Allow assessment of capacity
- Arrange additional repair

More advice for your project
An old wall needs a substrate assessment
In renovation, multiple layers of paint, wallpaper and plaster can be placed over each other. A clean exterior does not exclude a weak interlayer. Ask which layers remain and what assessment this choice is based on.
Discuss these points for your home
- Pass on previous treatments if you know them.
- Report moisture or fungal history.
- Set up what happens to unexpectedly loosening parts.
