The answer to your situation
In concrete count adhesion, pollution and flatness. Let the ceiling be assessed before the plaster layers are built up.
See the finish in detail.
What should you check first?
A concrete ceiling can have smooth parts, seams and remains of previous treatments. This affects the preparation. Send images of the entire ceiling and details of places where the old finish is damaged. Also report leakage or earlier repair, so that it does not disappear under the new layer.
How does this affect your choice?
The chosen patch and pre-treatment must fit the concrete and the required layer thickness. Different products have different conditions of application. Let the plasterer determine which surface is suitable; a primer is not selected only on colour or on what happens to be available.
Planning the next step
Discuss seams, wall edges and desired finishes. A new finish also changes the connection to light points and fixed parts. Plan enough space for drying and painting. Check the finish at delivery based on pre-arranged conditions.
Practical checklist
- Show seams and repair
- Report old treatments
- Ask for appropriate pre-treatment
- Align light points

More advice for your project
Notice different parts within the same ceiling
A concrete ceiling can be attached, have repair strips and remains of previous treatments. Pass those spots, even if they seem small. The ceiling will soon be seen as a single surface; the preparation should take into account the differences in the substrate.
Discuss these points for your home
- Report previous leaks and repairs.
- Let the suitability of the chosen pre-treatment be assessed.
- Tune out ceiling edges and cutouts before execution.
