Oh, ceiling just scraped and refinished from stomp brush to small knockdown...with a few "okay" drywall patches--if the two differ in hiding stuff

The painter should have to repaint on his own dollar, since you requested premium from the beginning, and he is the one that changed it.

SW Premium Ceiling has an LRV of 92 while SW Promar 200 Extra White has an LRV 86 so Premium is whiter and brighter. Also, SW claims that Premium's sheen is "ultra-flat" so presumably it would show fewer ceiling imperfections than Promar flat.

Note that there are three Promar paints: 200, 400, and 700. You should ask which was applied.

From Copilot Ai:

• ProMar 200 — Mid‑tier contractor paint; noticeably better resins, smoother application, stronger film. Considered the “workhorse” of the line.
• ProMar 400 — Entry‑level contractor paint; designed for cost efficiency and large new‑construction jobs. Often described by Sherwin‑Williams staff as “bare minimum.”
• ProMar 700 — Economy-grade; used when extremely low cost is the priority (commercial repaints, large apartment turnovers). Sherwin-Williams positions it below 400 in durability and hide.

If you’re choosing among the three:

• Pick ProMar 200 when you want the best performance in the contractor-grade tier.
• Pick ProMar 400 only when cost matters more than durability and finish quality.
• Pick ProMar 700 only for extremely budget-driven, low-wear environments.

wow! Yeah they left the can behind for touch ups I guess. But all it says is Sherwin Williams promar ceiling paint interior latex flat, white, and then there's a number at the bottom: A27 W 50 50 6508-68060. i was just hoping to get as white and bright as I could. The color of this is darker than the white I choose for the walls which won't do for an 8' ceiling. I bet it's the 200, I'll talk to him. Thanks for the info.

Sherwin-Williams appears not to publish the LRV of ProMar Interior Latex Ceiling Paint. The LRV of Sherwin‑Williams Premium Ceiling Paint is 92. (For comparison, the LRV of Behr Ultra Pure White is 94 which is the brightest white paint available.**) So if you want the whitest ceiling paint you should apply SW Premium, not Promar. Copilot Ai reports Premium sells for about $50/gallon*; Promar sells for about $32–$35 ($25–$30 for contractors).
