Drywall repair guide
Joint compound needs suitable drying conditions between finishing stages. Patch size, product selection, temperature and humidity affect the schedule. Painting also depends on the repaired surface being ready.
What to discuss before work starts
Ask for the expected sequence of visits. Avoid treating a promised arrival time as a guaranteed finish time.
Put the scope in writing
Confirm the affected surface, repair method, finish boundaries, room access and any separate work before scheduling. The condition of concealed material can change what is needed.
