Top pick for a value-minded repaint. At $33 to $38 a gallon it hides like paint that costs more, the base is genuinely zero-VOC and GREENGUARD Gold certified, and it is forgiving to roll — long open time, low spatter, and it does not grab halfway up a wall. The one-coat guarantee is real inside the 1,000-plus listed colors and only there. What you trade away is deep-color richness, which Aura still owns, and burnish resistance in a high-traffic eggshell by year three.
Interior or Exterior — Get the Right Can
PPG's naming is a maze and Timeless has siblings that look almost identical on the shelf. This review covers interior Timeless. The one mistake worth avoiding is walking out with the exterior can for an interior wall.

Dry, Recoat, and the First Month
Timeless is touch dry in 30 to 60 minutes and takes a second coat at 2 to 4 hours, so two coats fit in a day without any planning. Full cure is about 14 days. Two practical notes come out of that. Washability arrives with time, not with the first hour: at month two a wet rag with dish soap took greasy fingerprints off a switchplate wall and crayon off a hallway with no ghosting. And touch-ups blend cleanly inside the first month, then start to flash as the wall ages — after that you are re-rolling the wall rather than dabbing a spot. Fix your dings early and keep a labeled quart from the job.
When It Goes Wrong — and How to Fix It
It needed two coats even though the can says one
Why it happens: The one-coat guarantee covers 1,000-plus specific colors, not the whole deck. That sounds like everything until you fall in love with a custom deep color that is not on the list. Patchy repairs and a big color jump also push it to two coats.
The fix: Check whether your color is on the guaranteed list before you commit. Off the list, or over patched repairs, budget two coats and price the job that way. Behr Marquee's one-coat collection works the same way — the fine print is the same trap in both cans.
You bought Timeless Exterior for an interior wall
Why it happens: The names are nearly identical on the shelf. The exterior resin is built for weather, not for wipe-down, and it smells stronger in a closed room.
The fix: Return it and get the interior can. Nothing about the exterior product is a good match for a bedroom wall, and the money you save by using it up is not worth the odor or the finish.
Polished shiny spots in a hallway at year three
Why it happens: That is burnishing — the wear you get where shoulders and hands rub a wall. In a hallway that takes shoulder-rub traffic, we see polished spots in eggshell by month 30, where a premium matte in the same hallway shows none at month 36.
The fix: For a shoulder-rub hallway you want perfect years from now, spend up a tier. Timeless is a value paint and this is the main reason it is not a forever-room pick. In ordinary rooms it never shows.
A deep color smells stronger than a zero-VOC paint should
Why it happens: The base is genuinely 0 g/L, but universal colorants carry a small VOC load. A pastel adds almost nothing; a deep, heavily tinted color adds a measurable trace. "Zero" stops being literally true the moment a deep base gets loaded with colorant.
The fix: Treat a saturated color as low-VOC rather than zero and ventilate the first day like you would with any paint. The GREENGUARD Gold certification is the number that matters for indoor air, and Timeless holds it either way.
Application Settings That Work
- BRUSH
- Forgiving. Long open time, low spatter, and it does not grab the roller halfway up a wall, which is why a first-time painter gets a clean finish out of this can more reliably than out of a fussier premium paint. It brushes well on cut-ins for a value paint. A 3/8-inch microfiber cover is the roller that pulled a guaranteed-color teal over beige in one pass.
- PRIMER
- Self-priming on a clean, previously painted, evenly toned wall. On bare drywall, glossy trim, water stains, or a drastic color change, prime first with a bonding or stain-blocking primer. Self-priming is a convenience claim, not a magic one — when in doubt on a problem surface, prime.
Timeless vs Behr Marquee vs Glidden Diamond
All three sit in the same Home Depot aisle at three different prices, and the choice comes down to what you want to pay for. Marquee is the upgrade, Diamond is the downgrade, and the gaps are not the same size in both directions.
| PPG Timeless | Behr Marquee | Glidden Diamond | |
|---|---|---|---|
| Price per gallon | $33–38 | $48–58 | $23–27 |
| One-coat hide | Honest inside the 1,000-plus listed colors. Outside them, two coats. | More aggressive across a wider color change, especially red-to-gray and dark-over-light. Listed colors only. | No real one-coat guarantee. Two coats on most color changes. |
| Washability | Survives a real kitchen wipe-down at month two without burnishing, in eggshell and up. | Strong. | Softer wash resistance; burnishes under the same rag. |
| VOC | Zero-VOC base, GREENGUARD Gold. Deep tints add a trace. | Low-VOC, not zero. | Not the selling point. |
| Burnish at year three | Some polish in a high-traffic eggshell by month 30. | Slightly better at the two-to-three-year mark. | Weakest of the three. |
| Rolling forgiveness | The easiest can here for a nervous DIYer to get a clean wall out of. | Good. | Fine, but you will be doing it twice. |
| Where it wins | Best wall-per-dollar in the store. Bedrooms, living rooms, rental repaints. | The cleanest possible one-coat on a wide color change, plus a lifetime warranty. | Closets, ceilings, garages, and rentals you will repaint inside three years. |
For the cleanest possible one-coat on any color, Marquee — $20 a gallon more, and it hides a shade better across more colors. For the best wall-per-dollar in the same store, Timeless: $20 a gallon over an eight-gallon house repaint is $160 back in your pocket, plus a zero-VOC base for a sensitive household and the easier roll for a first-timer. Diamond only makes sense where the wall does not matter — closets, ceilings, garages, and short-cycle rentals.
What It's Good At
- +Hide for the dollar — a guaranteed-color teal pulled solid over beige in one pass with a 3/8-inch microfiber cover
- +A genuinely 0 g/L base with GREENGUARD Gold certification, mild enough that a closed nursery was usable the same night
- +Forgiving to roll: long open time, low spatter, no grabbing halfway up a wall
- +Washability that holds — greasy fingerprints and crayon came off at month two without ghosting
- +The full PPG deck plus Glidden and Home Depot exclusive colors, tinted at any counter in fifteen minutes
- +Two coats in one day, thanks to a 2-to-4-hour recoat
What It's Not Good At
- −Deep-color depth — next to the same navy in Aura it reads a touch flat and chalky
- −One-coat outside the 1,000-plus listed colors, where it is a two-coat paint like any other
- −Burnish resistance in a shoulder-rub hallway, where polished spots show in eggshell by month 30
- −Staying literally zero-VOC once a deep base is loaded with colorant
- −A steam-heavy bathroom with no exhaust fan, which wants a mildew-resistant formula built for it
Honest Alternatives
Same PPG family, the rung below, same Home Depot counter. Two coats on most color changes, softer wash resistance, no real one-coat guarantee. Right for closets, ceilings, garages, and rentals you will repaint inside three years.
The $20-a-gallon upgrade in the same aisle. Hides a shade better in one coat across more colors and resists burnish slightly longer. Loses to Timeless on price and on VOC, since Marquee's base is low-VOC rather than zero.
Color depth Timeless cannot reach and burnish resistance it cannot match at year three. About $50 more a gallon, and it shows on a deep accent wall in a forever home.
Timeless Questions, Answered
Is PPG Timeless worth it?
Yes, as long as you are not chasing a deep, moody color. At $33 to $38 a gallon it is the best wall paint Home Depot sells under $40: it hides like paint that costs more, the base is zero-VOC and GREENGUARD Gold certified, and it is forgiving to roll. What you give up is deep-color richness, which Benjamin Moore Aura still owns, and some burnish resistance in a high-traffic eggshell by year three.
Does PPG Timeless really cover in one coat?
In one of the 1,000-plus guaranteed colors, on a primed, evenly toned wall, usually yes. We took a beige base to a mid-tone teal in one pass and it pulled clean. Outside that color list, or over patchy repairs and a big color change, plan on two coats. The guarantee only applies to the listed colors, which buyers skim past.
Is PPG Timeless actually zero-VOC?
The base is 0 g/L. Once it is tinted, the colorant adds a trace, so a deep custom color is no longer technically zero. It is still very low and GREENGUARD Gold certified. The smell on application is mild and the room is liveable the same evening. Do not expect literally zero in a saturated navy.
Does PPG Timeless need primer?
On a clean, previously painted, evenly toned wall, the paint-and-primer handles it. On bare drywall, glossy trim, water stains, or a drastic color change, prime first with a bonding or stain-blocking primer. Self-priming is a convenience claim, not a magic one. When in doubt on a problem surface, prime.
How does Timeless compare to Behr Marquee?
Marquee hides a shade better in one coat across more colors and resists burnish slightly longer. Timeless wins on price by about $20 a gallon and on VOC, since its base is zero-VOC and Marquee's is low-VOC. For a value repaint, Timeless. For the most aggressive one-coat on any color, Marquee.
Is Timeless better than Glidden Diamond?
Yes, and they are both PPG-owned. Timeless hides better, resists stains better, and washes better. Glidden Diamond is the cheaper rung at roughly $25 a gallon and it shows in two-coat jobs and softer wash resistance. Buy Diamond for closets, ceilings, and rentals you will repaint soon. Buy Timeless for any wall you will actually live against.
Which sheen should I use in which room?
Eggshell is the volume interior sheen and the default for bedrooms and living rooms. Satin or semi-gloss for kitchens and baths, where the wall gets wiped. Flat for ceilings and low-traffic bedrooms. Washability holds up in eggshell and up, so a flat wall in a hallway is not the place to save money.
Can I use Timeless in a bathroom?
In a normally ventilated bath, yes — satin or semi-gloss. In a steam-heavy bathroom with no exhaust fan, no. That room wants a mildew-resistant formula built for it, not a general wall paint. Use the moisture-specific picks when the mirror fogs every morning.
How long before I can recoat or wash it?
Touch dry in 30 to 60 minutes, recoat at 2 to 4 hours, so two coats fit in one day. Full cure runs about 14 days. Real washability shows up with time — at month two a wet rag with mild dish soap took fingerprints and crayon off without ghosting. Do touch-ups inside the first month, while they still blend.
