Buy it for chalky, sun-beaten siding and deep colors. Permanizer grips lightly chalked old paint better than anything in its tier, holds a deep color instead of fading to a ghost of it, and goes on down to 35°F when most exterior acrylics quit at 50. It won a three-year outdoor weathering test against Emerald, Marquee, and Aura. At $51.98 a gallon at Home Depot it is no longer premium-priced; the same gallon runs $65 to $75 at a store counter.

Recoat: Label Time vs Real Time
Two recoat numbers float around this paint and both are correct — they answer different questions. The label and the pro franchises quote about a 2-hour recoat window, and in ordinary conditions on sound siding in a mid-tone, that is fine. My own rule is a full 24 hours before the second coat when tannin blocking or adhesion over a marginal surface is the whole job, because that is when a rushed recoat traps moisture and softens the bond. Touch dry runs 3 to 6 hours. Follow the label when you are painting sound siding in a mid-tone; take the day when you are on cedar, redwood, or chalk. The 35°F floor is real but it slows cure hard, so push the recoat window in the cold and never paint a wall the evening dew will hit before it skins.
When It Goes Wrong — and How to Fix It
New paint peeling off chalky old siding
Why it happens: Most exterior acrylics need you to wash chalk back to bare film or they let go in two years. Permanizer bites into a lightly chalked surface and holds, which widens the margin for error — but heavy chalk still beats it, and the warranty assumes proper prep.
The fix: Pressure-wash first, every time. If chalk still rubs off on your hand after washing, spot-prime it with Seal Grip before the topcoat. The adhesion-over-chalk claim buys you room for error, not permission to skip the wash.
Brown stains ghosting through the topcoat months later
Why it happens: Cedar and redwood bleed tannin. The stain migrates up through the film and shows itself long after the job looks finished, usually because the primer was skipped or the second coat went on too fast for the tannin block to set.
The fix: Prime bleed-prone wood with Seal Grip, then give that first coat the full 24 hours before you recoat. The tannin-block job needs the dry time — the 2-hour label recoat is not written for cedar.
A deep red or high-chroma color looks thin after one coat
Why it happens: The label says complete one-coat hide and it is honest on most colors over a sound similar surface at the full spread rate. Deep reds, deep bases, and high-chroma colors are not most colors, and the can does not warn you loudly enough.
The fix: Put a gray-tinted Seal Grip primer underneath or budget a third coat. The three-year outdoor test found extra coats measurably cut fading, and the effect was strongest on blues — so on a saturated color that third coat buys hide and color life at the same time.
Blotchy sheen and a weak bond on brick
Why it happens: Brick is porous and alkaline. The topcoat needs a sealed, uniform surface under it or the sheen goes patchy and the bond never gets strong.
The fix: Prime brick first. Fiber cement is the opposite case — Permanizer self-primes on factory-primed fiber cement, which is why crews like it on new construction and re-side jobs. Know which of the two you are standing in front of.
A warranty claim that went nowhere
Why it happens: Limited lifetime covers cracking, flaking, and peeling on a properly prepared surface, original purchaser, residential. It does not cover failures from skipped prep. Paint over chalk you did not wash or bare cedar you did not prime, and the substrate failed, not the paint.
The fix: Document the prep — photos of the wash, the scraping, the primer — and keep the receipt. Also know what you are claiming: it is a product-replacement remedy, not a labor check.
Application Settings That Work
- BRUSH
- It levels. Cut in a long fascia run with a 3-inch sash and the brush keeps releasing paint to the end of the stroke. Lap marks on this one come from technique, not from the paint fighting you. It also holds a wet edge in heat better than most exterior acrylics.
- AIRLESS
- Sprays at 1500–2000 psi without much thinning. It rolls clean too, and the film build is heavier than the budget exteriors on the same shelf, which is part of what you are paying for.
- THINNING
- Little to none. It is built to spray at 1500–2000 psi as it comes out of the pail.
- PRIMER
- Self-priming on clean, sound, previously painted siding. Seal Grip on bare wood, chalking old paint, tannin-bleeding cedar or redwood, and new stucco. Prime brick — porous and alkaline, it needs a sealed uniform surface. Do not prime factory-primed fiber cement; Permanizer self-primes there. Pressure-wash, scrape every loose flake, and sand the feather edges so they do not telegraph. The warranty assumes you did all of it.
Permanizer vs Behr Marquee Exterior vs Sherwin-Williams Duration
The first two sit on the same Home Depot shelf, which is the choice most people are actually making. Duration is the step up in price and in film. Read the price row twice — it is not the one you would have expected two years ago.
| Permanizer | Behr Marquee Exterior | Sherwin-Williams Duration | |
|---|---|---|---|
| Price per gallon | $51.98 at Home Depot; $65–75 at a store counter | $65–70 at Home Depot | $80–95 at a Sherwin-Williams store |
| Three-year outdoor fade test | 1st place — least fading, best sheen retention, best dirt resistance | Tied 3rd | Not in that test; Emerald tied 3rd |
| Over light chalk | Self-priming, and it is the headline claim | Self-priming since the current reformulation, but weaker over heavy chalk | Wants clean, dry, prepped substrate like any of them |
| Film and crack bridging | Heavy film build; levels a touch nicer under a brush | Slick dirt-shedding film | Thicker and more elastic — bridges hairline cracks best |
| Cold floor | 35°F surface and air | 35°F, must hold above 35°F for 4 hours | Not the reason to buy it |
| Recoat | About 2 hr on the label; 24 hr is my rule on cedar or chalk | About 2 hr | Follow the label |
| One-coat hide | "Complete one-coat hide" on the label — not on deep or high-chroma colors | One-coat collection of 700-plus colors, and it means something there | Not sold on a one-coat promise |
| Where you buy it | Home Depot and Pittsburgh Paints Co. stores | Home Depot exclusive | Sherwin-Williams store |
Permanizer is the value play here, which is not a sentence anyone could have written about it two years ago. It costs less per gallon than Marquee at the same register and it beat Marquee in the only long-run outdoor test either has been through. Take Marquee on a light-color repaint where the one-coat collection actually means something, or any weekend Behr's sale cycle drops it below Permanizer. Pay for Duration when the siding moves a lot — older wood lap in a freeze-thaw climate — and you want the most forgiving film in the category. Everything else, especially chalky siding and deep color, is Permanizer.
What It's Good At
- +Adhesion over chalky old paint — it bites into a lightly chalked surface where a $40 gallon lets go in two years
- +Color retention in deep tones; at year three on south-facing zone 5 siding the color still reads as the color
- +Applying down to 35°F surface and air, when most exterior acrylics quit at 50°F
- +Mildew and algae resistance — a mildewcide plus a separate preservative keeps a shaded north wall cleaner into year two
- +Leveling off a 3-inch sash, so lap marks come from technique rather than the paint
- +Early moisture resistance if a shower rolls through shortly after you finish
- +Third-party evidence: first place in a three-year outdoor weathering test against Emerald, Marquee, and Aura
What It's Not Good At
- −The twenty-dollar-a-gallon spread between Home Depot and a store counter for the identical paint
- −Living up to "complete one-coat hide" on deep reds, deep bases, and high-chroma colors
- −A quick second coat on cedar, redwood, or chalk, where the label recoat is faster than the job wants
- −Warranty coverage when prep gets skipped — it is a product-replacement remedy, not a labor check
- −Beating a Glidden-tier gallon on sound siding in a pale neutral, where you would never see the difference
Honest Alternatives
The budget rung of the same portfolio, at Home Depot and Walmart. A clean acrylic for sound, previously painted siding in light-to-mid colors on a rental or a flip. Gives up adhesion over chalk and deep-color fade life — exactly the trade you are making.
Thicker, more elastic film that bridges hairline cracks better, with the same lifetime warranty. Costs more and wants an SW store. The pick when your siding moves a lot in a freeze-thaw climate.
The direct Home Depot rival and now the pricier of the two. Strong one-coat hide across a 700-plus color collection, slick dirt-shedding film, same 35°F floor. Placed behind Permanizer in the three-year test and is weaker over heavy chalk.
Permanizer Questions, Answered
Is PPG Permanizer sold at Home Depot?
Yes, since the Pittsburgh Paints Co. transition it is. Home Depot lists Permanizer in flat, satin, and semi-gloss at $51.98 per gallon and $252 per 5-gallon pail, both as pre-tinted colors and as tintable bases. Pittsburgh Paints Co. stores and independent dealers still carry it too, usually at $65 to $75 a gallon retail with contractor pricing below that, and the store counter is still the better spot for custom tinting.
Why does the can say Pittsburgh Paints instead of PPG?
PPG sold its U.S. and Canada architectural paint business to American Industrial Partners on December 2, 2024, for $550 million, and the business was renamed The Pittsburgh Paints Company. Permanizer kept its formula and its limited lifetime warranty but is being rebranded from PPG to Pittsburgh Paints, and former PPG Paints stores are now Pittsburgh Paints Co. stores. Same paint, new owner and label.
What replaced PPG Timeless exterior paint?
Permanizer did. The official product pages for Timeless Exterior now state it has been replaced by Permanizer, and Home Depot no longer stocks Timeless exterior — Permanizer took its shelf slot at about $52 a gallon. If you painted with Timeless before, Permanizer is the same acrylic family with a heavier film build, a 35°F application floor, and stronger adhesion over chalky paint.
How did Permanizer do in independent testing?
In a three-year outdoor weathering experiment by The Paint Pals that pitted it against Sherwin-Williams Emerald, Behr Marquee, Behr Pro E600, and Benjamin Moore Aura, Permanizer finished first: least fading, best sheen retention, best dirt resistance, and almost no peeling. It is one experiment, run in a Colorado climate on horizontally exposed boards rather than a house, so read it as a stress-test ranking rather than a lifespan prediction. The same test found extra coats measurably cut fading.
Does Permanizer need a primer?
On clean, sound, previously painted siding, no — it is self-priming there. On bare wood, chalking old paint, tannin-bleeding cedar or redwood, or new stucco, yes. Spot-prime or full-prime with Seal Grip. Brick gets primed too. Factory-primed fiber cement does not. The lifetime warranty assumes proper prep, and bare wood without primer is the fastest way to void it.
How does Permanizer compare to Sherwin-Williams Duration?
Close on performance, no longer close on price. Duration builds a thicker, more elastic film and hides hairline cracks better; Permanizer levels a touch nicer under a brush. Both carry a lifetime warranty and both want clean, dry, prepped substrate. Money decides it: Duration runs $80 to $95 a gallon at a Sherwin-Williams store, Permanizer is $51.98 at Home Depot. Pay for Duration when the siding moves a lot.
Can I paint with Permanizer in cold weather?
Down to 35°F surface and air temperature, and falling. That is lower than most exterior acrylics, which stop at 50°F, and it is a real edge for spring and fall jobs in the north. The catch: 35°F slows cure hard, so push the recoat window and do not paint a wall the evening dew will hit before it skins.
Is Permanizer worth it over the cheaper exteriors in the same family?
On sound siding in a light mid-tone, a Glidden-tier exterior does the job and saves you real money. Permanizer earns the upgrade on chalky weathered siding, deep saturated colors, and full-crew repaints where one trip beats a callback. It grips and builds film better than anything below it in the lineup. If your siding is clean and your color is beige, save the difference and spend it on prep.
How many coats on a deep color?
Budget three. The label's complete one-coat hide is honest on most colors over a sound similar surface, but deep reds, deep bases, and high-chroma colors are not most colors. Use a gray-tinted Seal Grip primer or plan a third coat. The three-year test found extra coats measurably reduced fading, strongest on blues, so the extra material buys hide and color life at once.
