Verdict — ★ 3.8 / 5

You patch a few nail holes, sand them flush, roll your color straight over the wall, and step back. In raking afternoon light the patches read back at you — slightly duller, slightly darker, little ghosts where the repair drank the paint differently than the wall around it. That is the everyday problem a primer is for, and it is exactly the job HGTV Home’s All-Purpose Power Primer is built to do well: a high-hiding, water-based sealer that evens out a porous or patched substrate so the topcoat lays uniform, blocks ordinary household stains, and leaves a mold- and mildew-resistant surface. It is Sherwin-Williams chemistry, sold only at Lowe’s under the HGTV badge, priced to sit on the budget shelf against KILZ.

For the common case — new or patched drywall, a glossy door you scuff-sanded, a wall with a few light stains — it does the work and does it cheaply. It is not the can for the worst stains, and that is the honest line you have to draw before you open it.

Buy this if: you want one affordable waterborne primer to seal new or patched drywall, even out repairs, block ordinary stains, and grip glossy or previously painted surfaces, inside or out — tinted gray when the topcoat is dark.

Skip this if: your real enemy is a deep set-in water ring, nicotine, or fire smoke (those want oil or shellac), or you are priming slick factory cabinet doors where maximum grip is the whole job (that wants a dedicated bonding primer).

What Is HGTV Home Power Primer?

HGTV Home by Sherwin-Williams is real Sherwin-Williams paint sold at Lowe’s under the HGTV name — the same arrangement Behr has with Home Depot. SW owns the brand and makes every gallon; the network lends the design-show credibility and the curated colors. In 2025 the brand expanded its primer shelf to nine lines, and the All-Purpose Power Primer is the everyday workhorse of that range: a water-based, high-hiding primer-sealer for walls, trim, and ceilings, rated for interior and exterior use across a wide spread of surfaces.

The pitch is breadth at a budget price. One can seals porous drywall and patches, blocks common household stains, and bonds well enough to grip glossy and previously painted surfaces once they are scuff-sanded. The dry film is formulated to resist mold and mildew, which matters on an exterior wall or a humid bathroom ceiling. It comes white for normal work and in a pre-tinted high-hiding Gray for when your finish coat is dark or saturated — the gray cuts the number of color coats you need on top. SW’s own marketing leans on a 2025 blind-test claim that pros and DIYers preferred it over KILZ 2 All-Purpose, which tells you precisely where it is aiming: the value end of the all-purpose primer aisle, not the specialist end.

Worth being clear about what it is not. This is not one of Sherwin-Williams’ pro-counter primers like ProBlock or Multi-Purpose Latex. It is the retail, budget-tier, Lowe’s-exclusive line. Same manufacturer, different product and a lower price — which is the whole appeal, and the whole limit.

The Chemistry — What This Primer Actually Does

Most people notice the failure without naming it. You roll a fresh coat over a patched, slightly stained wall, and a day later a faint brown shadow has crept up through the paint. Or you brush new latex onto a glossy door and a week later it sheets off at the first knock. Two different problems, one root cause: the topcoat met the substrate without the right layer in between.

Here is the chemistry. Every coating is pigment held in a binder — the resin that fuses, as the film dries, into the continuous layer that does the actual sticking and sealing. A waterborne all-purpose primer like this one is built on an acrylic-class binder carried in water. That choice buys you three things at once. First, sealing: the resin soaks into a porous or patched substrate and gives the topcoat a uniform, non-thirsty surface to coalesce on, so you don’t get the dull ghosting over repairs. Second, adhesion: an acrylic film keys onto glossy and previously painted surfaces better than a soft, cheap PVA sealer would, which is why a scuff-sand plus this primer lets new paint grip a slick door. Third, a tight, mildew-resistant dry film that holds up inside a humid bathroom or outside on a wall.

Now the limit, because it is the whole reason for the honest rating. A waterborne film has a ceiling on stain-blocking. When you topcoat, water re-enters the primed surface; a water-soluble stain — a reactivating water ring, nicotine, smoke residue — can partly dissolve and migrate up through a waterborne layer as that water evaporates, surfacing in your finish. That is not a defect in this primer specifically; it is true of every water-based stain blocker. The cure is a different chemistry: shellac (alcohol-borne) or oil dries to a tight, non-aqueous barrier the stain cannot dissolve its way through. HGTV Home knows this, which is why the same nine-line range includes an Oil-Based Power Primer Extreme for water, smoke, tannin, and grease.

The takeaway, given how the chemistry works: reach for Power Primer when the job is sealing, evening out repairs, and ordinary stains — its real strengths. When the stain is heavy and water-soluble, spot-prime it first with shellac or the oil-based sibling, then carry on. Match the layer to the problem and the topcoat lays down right the first time.

What It’s Good At

• Sealing new and patched drywall. This is the core job and it does it well for the money. The high-hide film buries spackle spots and skim-coat repairs that flash through cheaper paint, so the finish coat reads uniform in raking light.
• One can for a mixed, budget repaint. Walls, trim, and ceilings; drywall, wood, masonry, and primed metal; interior and exterior. For the typical homeowner job that has a little of everything, you carry one inexpensive primer instead of three.
• Gripping glossy and previously painted surfaces. Scuff-sand a glossy door or oil-painted trim and the acrylic film keys on reliably, giving your new latex a surface it can actually bond to instead of sliding off.
• Fast, low-fuss application. Waterborne means low odor, soap-and-water cleanup, and a quick recoat — on a clean wall you can prime and topcoat the same day. It rolls and brushes smooth without much fight.
• A pre-tinted gray for dark colors. The high-hiding Gray version is genuinely useful: under a saturated or near-black topcoat it cuts a coat off the finish, which is real money and time saved on a deep accent wall.

What It’s Not Great At

• The worst stains. It is a waterborne film, and like every waterborne stain blocker it has a ceiling. Deep set-in water rings, nicotine, and fire smoke can reactivate and bleed up through it. For those, spot-prime with shellac (Zinsser B-I-N) or step up to HGTV Home’s own Oil-Based Power Primer Extreme — do not learn this after the topcoat is on.
• Slick factory cabinet doors. It adheres well to scuff-sanded gloss, but on the slickest substrates — melamine, laminate, hard factory cabinet enamel — a purpose-built bonding primer keys on with a firmer, longer-lasting grip and less prep. If cabinets are the whole job, that is the better tool.
• A light tint, not a deep base. Beyond the factory Gray, this is not a deep-tint undercoater you load with colorant to bury a near-black finish. Under very dark topcoats, lean on the pre-tinted gray and on the finish coat to do the burying.
• One retailer, on its own clock. It is Lowe’s-exclusive, so if your store is a Sherwin-Williams or a Home Depot, you can’t grab it on the same trip as the rest of your supplies. A small thing, but it shapes the convenience math.

Who It’s For / Not For

Buy this if: you want an affordable, do-most-things waterborne primer for a normal repaint — new or patched drywall, a few light stains, a glossy door or two, interior or exterior — with low odor, water cleanup, and a gray option for dark colors. For the everyday homeowner job that has a bit of everything and a budget, this is a sensible default, and it is SW-made.

Skip this if: the job is a specialist’s job. Heavy nicotine, smoke, or a deep water ring wants oil or shellac on the spot. Slick factory cabinet doors want a dedicated bonding primer. A near-black finish over a light wall wants a true deep-base undercoater. Buy the specialist when the problem is concentrated, and keep Power Primer for the broad, ordinary work it’s actually good at.

Honest Alternatives

For the Worst Stains: Zinsser B-I-N Shellac-Based (~$22–26/qt)

The opposite chemistry, on purpose. Shellac dissolved in alcohol dries to a tight, non-aqueous film that locks down heavy nicotine, smoke, set-in water rings, and odors that any waterborne primer eventually lets pass. It smells, wants ventilation, and cleans up with ammonia or alcohol — but for stain blocking it is the benchmark. Use it as a spot primer over the bad stains, then Power Primer or your topcoat over everything else. (HGTV Home’s own Oil-Based Power Primer Extreme is the in-house version of this step-up if you want to stay in one brand at Lowe’s.)

For Slick Cabinets and Laminate: KILZ Adhesion Bonding Primer (~$28–34/gal)

Where Power Primer is the all-rounder, a bonding primer is the adhesion specialist. KILZ Adhesion is built around a resin formulated to grip the slickest substrates — melamine, laminate, glazed tile, hard factory enamel — with minimal prep, exactly where maximum bite is the whole concern. It is the right pairing when you are repainting cabinet doors and stain-blocking is beside the point. For mixed walls and ordinary surfaces, Power Primer covers more ground for less.

The Budget Cross-Shop: KILZ 2 All-Purpose (~$20–26/gal)

The very product HGTV’s marketing benchmarks itself against. KILZ 2 is a waterborne all-purpose primer-sealer in the same chemical family and the same price bracket, stocked at every big-box store. It seals, hides, and bonds for general interior and exterior priming with water cleanup. SW’s blind-test claim says testers preferred Power Primer; in practice they are close cousins, and the real tiebreaker is which store you’re standing in. If you’re at Lowe’s, Power Primer; if KILZ is what’s on the shelf in front of you, it does the same broad job.

Where to Buy

Buy it at Lowe’s — it is the brand’s only home. HGTV Home cans aren’t at Home Depot (that aisle is Behr) or at Sherwin-Williams company stores, which sell SW’s own primers instead. The quart suits a single door or a handful of stains, the gallon covers a normal room’s worth of drywall, and the 5-gallon drops the per-gallon cost on a whole-house prime. Before you open it, it’s worth knowing exactly when a primer earns its keep over a paint-and-primer paint — that’s the difference between a uniform wall and a day of ghosting.
