What the work should include
Choose a representative area that includes typical joints or repairs. Define which preparation, finishing, primer and paint will be included in the sample. Review it only after the planned stages are complete, because unfinished compound does not show the same appearance as a painted wall.
Choices to make before work starts
Use normal room lighting and viewing positions, including daylight if relevant. Record the approved appearance and the work boundary. If a sample is rejected, agree on the next adjustment before applying the same treatment across the room.
What affects the estimate and schedule
Sample size, coating selection and requested revisions affect planning. Send photos of the most demanding wall and explain what you dislike about its current appearance.
Helpful project information
- Existing texture in close-up and under side lighting
- Desired smoothness and planned paint sheen

A question about this work
Is a small sample in a hidden corner enough?
Not if it misses the room's difficult light or surface condition. Choose a location representative of the final work.
