Executed ceiling refinishing in the great room. Applied Sherwin-Williams Duration Home Ceiling Paint in flat finish for superior coverage and light-diffusing properties. Utilized an 18" roller with 3/4" nap for efficient application and minimal splatter. Implemented careful masking techniques using 3M ScotchBlue painter's tape to protect crown molding and wall interfaces. Performed necessary surface preparation, including spot-priming with KILZ Original to address minor water stains. Employed airless sprayer for initial coat to ensure even coverage on textured surface, followed by back-rolling for uniform appearance. Achieved flawless finish with no visible lap marks, enhancing room aesthetics and light reflectivity.
