Paint

Primers ranked for painting over dark rental walls

Someone painted the bedroom eggplant. Here is what covers it in two coats instead of five.

The bedroom in my friend Dell's apartment on Hampton Avenue in Northampton is eggplant. Not an accent wall. All four walls, the closet interior and, for reasons nobody in the building can explain, the window casing. A tenant three leases back did it, and the current lease says the room comes back "light neutral" or the deposit does not come back at all.

Dell asked how many coats of white it would take. The honest answer depends entirely on what you put down first, so we spent a Saturday finding out.

The wall and the patches

The paint underneath is a satin purple, dark, with a sheen you can see when the afternoon sun comes across it. A dab of it read out at the counter at the Sherwin-Williams store on King Street as roughly a 7 on their light reflectance scale, about as dark as interior latex gets before you are into black.

The plaster is 1920s and mostly sound, with two brown water stains near the ceiling from a roof problem the landlord fixed in 2019 and a run of nail holes where a headboard sat. We filled the holes Friday night and sanded Saturday morning.

Six primers, six patches, each 30 inches square, taped off along the north wall with the water stains split between two of them. One coat of primer on each, rolled with a 3/8-inch cover. Then the topcoat, the same gallon of Behr Premium Plus flat in an off-white for all six, rolled one coat at a time. After each coat we waited four hours and looked from the doorway in daylight. The count below is how many topcoats it took before Dell and I both stopped seeing purple. Room was 74 degrees. We ranked by that number and used smell and dry time to break ties.

1. Zinsser B-I-N shellac, $28 a quart

One topcoat. That is the whole review and it is not close.

B-I-N went on thin and a little orange-white, dried to touch in 20 minutes, and after one coat of off-white the patch was done. It killed both water stains outright, which none of the water-based primers managed.

The cost is your afternoon. The smell is severe, alcohol and something sweet under it, and it stayed in the apartment most of a day with the fan in the window. This is the primer's oldest complaint and it is a real one. Dell's cat spent the afternoon in the kitchen with the door shut because she objected loudly to the first ten minutes of it. You clean the roller with denatured alcohol or you throw it away, and we threw it away. In a one-bedroom where you also sleep, think about whether you can go somewhere for a night.

2. Zinsser Bulls Eye 1-2-3, tinted gray, $42 a gallon

Two topcoats, low smell, and the one I would tell a renter to buy.

We had the counter tint it to a medium gray, and gray is the trick nobody tells you about. Dark purple to white is a long jump for one coat of paint. Landing on gray first cuts it in half, because the white is only covering gray. After one topcoat the patch was a cloudy white, after two it matched the sample card. Ask for the tint. It saves you a gallon of finish paint.

Dry time was 60 minutes to recoat, honest at that temperature. Smell was mild and gone by evening. It did not block the water stains, and a faint tan halo came through the second topcoat there and had to be spotted with shellac anyway. For dark walls with no stains, this is the can.

3. Kilz Original, oil-based, $36 a gallon

Two topcoats. It handled one water stain cleanly and let the other ghost through as a ring.

The problem is time. The label gives you a recoat window measured in an hour or so, and in a bedroom that humid with the windows open it wanted most of an afternoon. We touched it at two hours and it was still tacky enough to pull on the roller. That is what pushes it below the Bulls Eye, because the entire point of a Saturday is that it ends. Brush cleanup is mineral spirits, and the odor sits somewhere between the shellac and everything else.

4. INSL-X Stix bonding primer, $52 a gallon

Two topcoats on the sanded areas, three where the satin purple was untouched.

Stix is built to grip rather than to hide, and it grips. Nothing peeled at the tape line, and on that glossy window casing it was the only primer that did not sit up like water on wax. As a hider it is average, and it is white out of the can, so you are asking the topcoat to do the whole jump. It is also the most expensive gallon here by ten dollars, which is easier to justify on trim and cabinets than on 400 square feet of bedroom.

5. Kilz 2 All Purpose, $28 a gallon

Three topcoats untinted. Two when we had a second gallon tinted to the same medium gray, which is the clearest evidence in this test that the gray step is worth the trip.

It is cheap, nearly odorless, dry to recoat in 45 minutes, and it rolled without spatter. On a white or a beige wall this would be plenty and I would not think twice. Against eggplant, the untinted version is a slow way to spend a gallon of finish paint.

6. Behr Premium Plus interior drywall primer and sealer, $19.98 a gallon

Four topcoats and we stopped there because the patch still was not right.

This is a PVA-type sealer and the can says what it is for, which is new drywall. It evens out how thirsty fresh board is, and there is very little pigment in it. On dark satin paint it sits there looking translucent, and it stayed soft under the first topcoat long enough to streak where the roller dragged. It is the cheapest gallon on the shelf and on this wall it is the most expensive thing you can buy. Nothing wrong with the product. Wrong room.

What Dell actually did

Bulls Eye 1-2-3 tinted gray on all four walls, one coat, the two water stains spotted with the last of the B-I-N, then two coats of off-white. Fourteen hours over two Saturdays, about $190 in materials, and the room reads as light neutral from the doorway.

One thing to watch in these old apartments. The wall behind a radiator gets hot and the primer flashes there before you can roll back into it, so do that section first while the metal is cold.
