Drywall repair guide
Existing texture can vary with application technique, age and layers of paint. Matching a repair involves both its profile and its transition into the surrounding surface.
What to discuss before work starts
Show the texture in clear side lighting. Discuss a sample area and the boundary of the finish before approving the repair.
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.
