Ceiling paint is sold on a coverage number, and that number is close to useless on its own. The paints on this page are advertised anywhere from 250 to 450 square feet per gallon, and the one quoting the lowest coverage lays down the thickest film per coat.
The figure that actually predicts hide is volume solids. A gallon of any paint covers 1,604 square feet at 1 mil of dry film, so volume solids tells you how much film you get. At 46% solids a gallon gives 738 square feet per mil of dry film. At 29% it gives 465. That is 59% more film from the same gallon, and both products are sold as ceiling paint.
Across the seven ceiling paints measured here, volume solids runs from 28% to 46%. Six of the seven need two coats or more. One will do it in a single coat, with a condition attached.
How volume solids turns into film on your ceiling
Dry film is wet film multiplied by volume solids. Roll a 4.0 mil wet coat of a 40.3% paint and 1.61 mils are left once the water has gone. Roll the same 4.0 mils of a 29% paint and you are left with 1.16 mils. Same effort, same roller, 39% less paint on the ceiling.
Eight of the nine products checked here agree with that calculation to within a tenth of a mil. The exception is a color-changing ceiling paint whose sheet lists 3.8 mils wet, 28% volume solids and 1.3 mils dry. Multiply 3.8 by 0.28 and you get 1.06. The published dry film is 23% high, which matters if you are specifying a film thickness rather than just rolling until it looks even.
Why you cannot compare two ceiling paints on square feet per gallon
Coverage ranges are quoted at whatever film thickness the brand chose. One paint is rated 250 to 400 square feet because the bottom of that range is a 6.4 mil wet coat. Another is rated 400 to 450 because it assumes a 3.6 to 4.0 mil coat.
Divide coverage by dry film and the ranking changes. Here is what a gallon of each buys you at a fixed 1 mil of dry film, which is the only comparable version of the number:
| Ceiling paint | Volume solids | Advertised coverage (sq ft/gal) | Sq ft per gallon at 1 mil dry |
|---|---|---|---|
| BEHR Ultra Stain-Blocking Ceiling | 46% | 250–400 | 738 |
| Zinsser Ceiling Paint & Primer In One | 42.3% | 250–400 | 678 |
| Benjamin Moore Waterborne Ceiling Paint | 40.3% | 400–450 | 646 |
| KILZ Stainblocking Ceiling Paint | 38% | 250–400 | 610 |
| Sherwin-Williams Premium Ceiling Paint | 33% | 350–400 | 529 |
| Sherwin-Williams ProMar Ceiling Paint | 29% | 350–400 | 465 |
| Insl-x Color-Changing Ceiling Paint | 28% | 400–450 | 449 |
The paint at the top of that table advertises the lowest coverage in the group, 250 square feet at its heaviest coat, and still delivers 64% more film per gallon than the paint advertising 450. Buy on the number printed largest on the label and you pick the thinnest paint in the group, then wonder why the second coat is still letting the old ceiling through.
Is ceiling paint really different from flat wall paint?
The usual answer is that ceiling paint is thicker, carries more solids and spatters less. Inside one major brand’s own range, that is backwards. Its ceiling paint sits at 40.3% volume solids and builds 1.4 to 1.6 mils dry. Its premium flat wall paint sits at 46% and builds 1.6 to 1.9 mils from the same 3.6 to 4.0 mil wet coat. The wall paint is also the thinner of the two in the can, at 98 KU against 103 KU, and it is the one sold on excellent spatter resistance. The ceiling paint claims only that it resists spattering when rolled.
At another brand the rule does hold, but only just. Ceiling paint 46% against flat wall paint 43%, and 105 to 115 KU against 100 to 110 KU. Three points of solids and five units of viscosity.
| Ceiling paint | Flat wall paint, same brand | |
|---|---|---|
| Benjamin Moore — volume solids | 40.3% | 46% |
| Benjamin Moore — dry film per coat | 1.4–1.6 mils | 1.6–1.9 mils |
| Benjamin Moore — viscosity | 103 KU | 98 KU |
| Benjamin Moore — sheen at 85° | 0–2 | 1–4 |
| BEHR — volume solids | 46% | 43% |
| BEHR — dry film per coat | 1.8–2.9 mils | 1.7–2.8 mils |
| BEHR — viscosity | 105–115 KU | 100–110 KU |
| BEHR — sheen at 85° | 0–3 | 0–4 |
The spread among ceiling paints, 28% to 46%, is three times wider than the gap between ceiling and wall paint at either brand. “Ceiling paint” sets no floor on the formula.
What the category does buy you reliably is narrower and more useful than the marketing suggests: a white base that is not meant to be tinted deep, the lowest sheen in the brand’s lineup, and on two of the seven, a binder sold to hold back water stains. Film build is not on that list. If you want film, read the solids figure.
Sheen is measured at 85 degrees, which is the angle you see a ceiling at
Flat paints are read on a gloss meter set to 85 degrees rather than the usual 60, because at 60 degrees a flat returns almost nothing and every product scores the same. Eighty-five degrees is grazing light — light arriving almost parallel to the surface. That is exactly how a ceiling is lit by a window at nine in the morning, which is why the 85 degree figure is the one worth reading on a ceiling paint.
Across the eight products the range is 0 to 5 units. Two ceiling paints and one ultra flat sit at 0 to 2. A color-changing ceiling paint sits at 2 to 5. A premium flat wall paint measures 0 to 4 at 85 degrees and 0 to 4 at 60. Three units at 85 degrees is the difference between roller laps you have to hunt for and roller laps you see from the sofa.
This is the one place where ceiling paint reliably beats wall paint from the same brand, and it is a smaller margin than the price gap suggests: 0 to 2 against 1 to 4.
What one coat really means, paint by paint
The phrase “one-coat coverage” appears on a lot of ceiling paint labels. Only 1 of the 7 paints here will actually do it, and it comes with a condition.
| Ceiling paint | Coats needed |
|---|---|
| Zinsser Ceiling Paint & Primer In One | 1 coat in most cases — and only unthinned |
| Benjamin Moore Waterborne Ceiling Paint | 1 or 2 coats |
| BEHR Ultra Stain-Blocking Ceiling | 2 coats minimum on new or uncoated surfaces |
| KILZ Stainblocking Ceiling Paint | Multiple coats for full stain blocking and hide |
| Sherwin-Williams Premium Ceiling Paint | Self-primed, 2 coats |
| Sherwin-Williams ProMar Ceiling Paint | 2 coats over primer |
Sherwin-Williams Premium Ceiling Paint is advertised on excellent self-priming one-coat coverage, and specified at two coats self-primed. When a brand contradicts itself like that, plan around the harder of the two numbers.
The honest version is the Zinsser one: at 42.3% volume solids and 1.5 to 2.0 mils dry, a single coat is realistic on a sound, previously painted, unstained ceiling, and only if you do not water it down. Over new drywall, over a repair, or over anything that used to be a different color, all 7 need 2.
Recoat windows run from 1 hour to 4, and that decides your weekend
Every one of these paints is touch dry inside an hour, and most are quoted at exactly one hour. The recoat figure is where they separate.
| Ceiling paint | Dry to touch | Dry to recoat |
|---|---|---|
| BEHR Ultra Stain-Blocking Ceiling | 30 minutes | 1 hour |
| Zinsser Ceiling Paint & Primer In One | 1 hour | 1 hour |
| Benjamin Moore Waterborne Ceiling Paint | 1 hour | 1–2 hours |
| KILZ Stainblocking Ceiling Paint | 1 hour | 2 hours (4 for full stain blocking) |
| Insl-x Color-Changing Ceiling Paint | 1 hour | 2 hours |
| Sherwin-Williams Premium Ceiling Paint | 1 hour | 4 hours |
| Sherwin-Williams ProMar Ceiling Paint | 1 hour | 4 hours |
All figures are at 77°F and 50% relative humidity. A cold room or a damp one stretches them.
On a 12 by 15 foot bedroom ceiling, 180 square feet, a one-hour recoat means cutting in, rolling, having lunch and rolling again before the afternoon is out. A four-hour recoat means coat one in the morning and coat two after the school run, or more realistically a second day with the furniture still sheeted.
One label quotes a 1 hour dry and a 2 hour recoat for a paint that is touch dry in 30 minutes and ready to recoat in 1. That one errs on the safe side, which is the right direction for a label to be wrong in.
What the color-changing paints really buy you
Two of these go on pink and dry white so you can see where you have missed. The timing is the catch: one fades in under an hour against a 2 hour recoat, the other changes in about an hour against a 1 hour recoat. In both cases the guide color is gone by the time coat two is allowed, so the pink helps you on the first coat and then leaves you rolling the second one blind, the same as any white paint.
That is still worth having on a ceiling, where a missed patch is directly above your head and almost impossible to spot from the ladder. It is not worth paying for twice if you were only ever going to apply one coat.
Six products for a ceiling, and what each one is actually for
Three go on a whole ceiling. The other three fix a specific ceiling problem. Treat all six as interchangeable and you get a low-sheen bedroom ceiling full of lap marks.
1. KILZ Stainblocking Ceiling Paint
38% volume solids, 250 to 400 square feet per gallon, 1.5 to 2.4 mils dry, 49 g/L VOC, 95 to 105 KU. Touch dry at 1 hour, recoat at 2, or 4 for stain blocking at full strength — and do not thin it if you want that. The one for a yellow halo over the stove, or a bathroom ceiling that has leaked.
2. Benjamin Moore Ultra-Premium Ceiling Paint
The one the search engines keep nominating: 40.3% volume solids, 400 to 450 square feet per gallon, 1.4 to 1.6 mils dry, 103 KU, sheen 0 to 2 at 85 degrees, ready to recoat in 1 to 2 hours. The real headline is 0 g/L VOC — the only zero here, against 47 to 50 for the rest. It is not the highest-build paint in the group; two others lay more film per coat.
3. Prestige Paints Interior Flat Paint and Primer
A flat interior wall paint sold as a color match, not a ceiling product — which for a tinted ceiling is an advantage. The chart above puts premium flat wall paint at or above most ceiling paints, so you lose no film getting the color. It carries slightly more sheen, and tinted ceilings show laps, so use a properly sized roller and nap.
4. Montage Signature Interior/Exterior Paint
Low sheen rather than flat, and that one word decides where it belongs: grazing window light is what sheen is measured in. Fine on a porch, garage or basement ceiling that gets wiped down. In a living room, pick a 0 to 2 flat instead and spend the difference on a decent drop cloth.
5. Roll On Wall and Ceiling Texture
Not a paint. A texture compound for rebuilding stipple or knockdown where a repair or a removed light fitting has left a smooth patch. Paint over it and it reads as a bright island however many coats go on, because the texture around it catches light differently. Texture, cure, then prime the patch with an oil-based primer or a drywall primer.
6. Rust-Oleum Metallic Accents
A decorative metallic for a feature ceiling — a tray ceiling, a powder room, an alcove. It catches light rather than killing it, so it shows every ridge, screw head and taped joint. Use it only over a ceiling you have skimmed flat.
Picking the paint for the ceiling in front of you
Is anything showing through?
A brown water ring, nicotine, or smoke above a woodburner needs a stain-blocking binder or a dedicated primer underneath. Rolling two coats of ordinary flat over a water stain gets you a faintly brown ceiling. Both stain-blocking ceiling paints here want the same thing: more than 1 coat, and no thinning. One of them also wants 4 hours between coats rather than 2 if you want the stain blocking at full strength.
New drywall, or a repaint?
New board and fresh joint compound drink paint at wildly different rates, which is what produces a patchy first coat. Prime the whole ceiling, not just the repairs, and plan on 2 coats over that primer regardless — all 7 paints here call for it over new board. On a repaint of a sound, clean, previously painted ceiling the 1-coat case can hold — but only in the same color, and only unthinned.
How high is it, and are you rolling or spraying?
Below about 9 feet a roller on a pole is faster than masking a room. Above that, or on a whole floor of ceilings, a sprayer wins. The tip sizes and pressures vary by paint and the ceiling sprayer tip and pressure figures are worth checking before you buy, because a 29% solids ceiling paint and a 46% one do not atomize at the same setting.
If you are rolling, the nap decides the finish as much as the paint does, and rolling technique decides whether the laps show. If you are spraying, budget the time to clean the gun properly afterwards; dried ceiling flat is unpleasant to remove.
Should you thin it?
Mostly no. Of the 7 sheets, 1 says do not thin at all, 2 say do not thin if you want the stain blocking or the single coat, and 2 say no reduction is needed. Only 2 allow a measured reduction, and both cap it: a maximum of 8 fluid ounces per gallon on one, half a pint — 8 ounces again — on the other. Thinning costs film in direct proportion to the water you add, and film is the whole point — the arithmetic of thinning latex paint works the same way on a ceiling as anywhere else.
Ceiling white versus bright white
Ceiling whites are deliberately softened. They carry a trace of gray or yellow so the ceiling reads as a surface rather than a light source, and so the slight unevenness every ceiling has is not thrown into relief. A true bright white alongside a warm wall color makes the ceiling look blue-gray by contrast.
Light reflectance value is the number to compare, and among the whites people actually put on ceilings it runs from about 82 to 90. Chantilly Lace sits at 90.04, Decorator’s White at 82.68, Icicle at 82.04. Those eight points are the difference between a ceiling that disappears and one that draws the eye upward; in a small room with a single window the lower figure almost always looks better, and in a tall room with north light the higher one earns its keep.
If you want the ceiling tinted rather than white, the standard approach is to take the wall color and have it mixed at 25% or 50% strength in a flat base. The ceiling reads as the same color family without closing the room in. Both of the premium ceiling paints here are tintable, though one is restricted to light colors only.
Whatever you pick, buy enough in one batch to do the whole ceiling. A 12 by 15 foot ceiling is 180 square feet, which at 400 square feet per gallon is 0.45 gallons a coat — so 1 gallon covers 2 coats with a little to spare, and there is rarely a reason to split the job across 2 cans. A ceiling is a single uninterrupted plane with no corner to break a batch change on, and a half-shade difference between two cans will show from the doorway.
Frequently asked questions about ceiling paint
Which color is best for a ceiling?
An off-white in the low 80s for light reflectance is the safe default, because it stays lighter than the walls without reading as a lit panel. Below roughly LRV 70 a ceiling starts to feel physically lower, which is fine in a room with 10-foot walls and oppressive at 8 feet. If the walls are a strong color, the usual move is the same color mixed at a quarter or half strength.
What is the best Benjamin Moore ceiling paint color?
The ultra flat ceiling line ships in a ceiling white base and takes tint, so the choice is really which white. Decorator’s White at LRV 82.68 and Icicle at 82.04 are the softer end and forgive an uneven ceiling; Chantilly Lace at 90.04 is the bright end and wants a flat, well-finished surface under it. For a standard 8-foot room the softer whites are the easier result.
What is the difference between Benjamin Moore Waterborne Ceiling Paint and Sherwin-Williams Premium Ceiling Paint?
Volume solids: 40.3% against 33%. Dry film per coat: 1.4 to 1.6 mils against 1.3. Coverage: 400 to 450 square feet per gallon against 350 to 400. VOC: 0 g/L against under 50. Recoat: 1 to 2 hours against 4. Sheen is a tie at 0 to 2 units at 85 degrees. The practical gap is the recoat window, which is four times longer on one of them.
What type of paint finish is best for ceilings?
Flat, and specifically a flat measured at 0 to 5 units on an 85 degree gloss meter. Anything with a readable sheen — eggshell, satin, low sheen — turns the grazing light from a window into a map of every roller stop and every taped joint. The exception is a bathroom or a kitchen ceiling you intend to wipe, where a washable low sheen is worth the lap marks.
What is the best paint to put on a ceiling?
Pick by the problem. Water stains or nicotine: a stain-blocking ceiling paint, unthinned, two coats. Sleeping in the room that night: the 0 g/L ultra flat. Trying to finish in one coat: a paint-and-primer ceiling product applied unthinned over a sound, previously painted ceiling of the same color. A tinted ceiling: a premium flat wall paint, which carries as much solids as most ceiling paints.
What are people saying about Sherwin-Williams Premium Ceiling Paint?
The two things that come up most are the whiteness, which the 0 to 2 sheen rating backs up, and the drying time, which it also backs up: 4 hours to recoat is the slowest in this group by a factor of two. Coats are the third. At 33% volume solids it lays 1.3 mils dry per coat, below four of the six other ceiling paints measured here, so plan on two whatever the label promises.
The short version
Read the volume solids figure, not the square feet per gallon; across these 7 ceiling paints it runs from 28% to 46%. Expect 2 coats unless the ceiling is sound, clean, already painted and the same color, and unless you leave the paint unthinned. Check the recoat time before you plan the day, because it ranges from 1 hour to 4 across otherwise similar products. And treat the sheen number at 85 degrees — 0 to 5 units across this group — as the finish spec that matters on a surface lit from the side.
Do that and the choice usually makes itself: stain-blocking for a marked ceiling, the zero-VOC ultra flat for a bedroom you want to sleep in tonight, and a premium flat wall paint if the ceiling is going to be any color other than white.
