The 30-Second Take

Purdy is the default brush in American paint stores. Walk into any Sherwin-Williams location, any decent paint counter at Home Depot, any pro paint shop on the West Coast, and the wall behind the register is mostly blue Purdy handles. The line covers wall and trim brushes (XL Glide, Clearcut, Black Diamond, White Bristle), mini rollers and roller covers (Colossus, White Dove, Marathon), the Power Lock telescoping pole system, and a thin layer of specialty tools like pad applicators, brush cleaners, and drop cloths. Most of it earns its place. Some of it is fine. A few specific picks beat anything Wooster or Corona sell, and a few specific picks lose by enough that you should know.

Top pick from the line: Purdy Clearcut Glide 2.5-inch angled sash. It cuts a cleaner line through waterborne trim enamel than any sub-$30 brush we’ve tested, and a pro painter on a cabinet or trim job will get back the $25 in saved caulk and recut time on a single project. Top loser: the budget White Bristle natural-bristle brushes, which only make sense for oil-based primer where you wouldn’t put a synthetic anyway. The rest of this article is what each line is actually for, where Wooster wins the head-to-heads, and where to spend.

What Purdy Actually Is

Purdy goes back to 1925, when a paint contractor named Stuart Purdy started making his own brushes in a Portland, Oregon basement because the brushes he could buy weren’t lasting through his commercial repaint contracts. The company spent the next eighty years as a Portland-based applicator manufacturer building brushes for the West Coast contractor market. The blue handles became regional shorthand for “pro tool” long before they were a national brand.

Sherwin-Williams acquired the parent business in 2004 and folded Purdy into the SW applicator division alongside Bestt Liebco and a small set of other roller and brush brands. The Portland manufacturing stayed (the brushes are still assembled in Oregon for the US market), the blue-handle identity stayed, and Purdy now ships through every Sherwin-Williams store at full pro pricing plus Home Depot, Lowe’s, Ace, and Amazon. The SW relationship is the same shape as Minwax: independent shelf brand, parent corporate ownership, no exclusive distribution.

The 2018 Clearcut redesign is the recent inflection. Purdy reworked the Clearcut Glide bristle blend specifically for waterborne urethane trim enamels (BM Advance, SW Emerald Urethane) that had taken over from oil-based trim, and the redesigned brush became the standard contractor pick for cabinet and trim work. Pre-2018 Clearcut was a good brush. Post-2018 Clearcut is the right brush.

The Line, Brush by Brush

XL Glide

The general-purpose pick. A nylon-polyester blend in the classic blue beavertail handle, sized from 1-inch to 3-inch, angled or flat. The bristles hold a generous load of paint and release cleanly into flat latex, satin acrylic, primer, and most interior wall paints. On a 9-foot wall cut at the ceiling line, an XL Glide 2.5-inch angled sash carries enough paint that you’re reloading every six to eight feet, which is the right tempo. Cleanup is quick: five minutes in warm water and a brush comb and the bristles spring back.

XL Glide’s strength is forgiveness. The bristle stiffness is in the middle of the range, which means it tolerates a variety of paints and a variety of hand pressures without misbehaving. New painters can use it without fighting it. Pros use it for fast wall work where finish quality is in the roller’s hands and the brush is just cutting the line. On enamel trim, it’s adequate; it’s not the right pick.

The trade-off is line quality. The bristle tips are not as fine as Clearcut’s, and on a sharp casing cut against a contrasting wall color, the line is slightly less crisp under raking light. For walls, irrelevant. For trim, switch tools. Purdy XL Glide at Home Depot runs $17-22 for the 2.5-inch angled sash.

Clearcut (Clearcut Glide)

The trim and cabinet pick. Purdy redesigned the Clearcut bristle blend in 2018 for waterborne urethane trim enamels, and the result is the cleanest line we’ve gotten from a sub-$30 brush. The bristle tips are finer than XL Glide, the bristle stiffness is slightly higher, and the handle is shorter and pencil-style for fingertip control instead of whole-arm sweeping. On a Benjamin Moore Advance or SW Emerald Urethane application, Clearcut leaves brush marks that level out fully inside the recoat window. XL Glide leaves marks that mostly level, and on a deep saturated color in raking light, the difference is visible.

Where Clearcut wins specifically: cutting trim against a contrasting wall color, painting kitchen cabinet doors and frames, applying enamel to interior doors and casings. The line at the wall edge is sharp enough that you can skip painter’s tape on careful work, which saves real time. Where it doesn’t help: rolling paint, ceiling cut-ins, exterior siding. Wrong tool for those.

Compare it to Wooster Silver Tip, which is the closest competitor in the designer-trim category. Silver Tip is a cleaner cut on the very first stroke and slightly softer in feel; Clearcut is more durable through a full quart of paint and holds the cut as the bristles load up. Most contractors I’ve worked with reach for Clearcut. Purdy Clearcut Glide 2.5-inch runs $22-28 at SW or Amazon.

Black Diamond

The premium nylon-polyester blend, positioned above XL Glide in finish quality and below Clearcut in trim-specificity. Black Diamond’s selling point is the way it lays paint down on a wall. The bristles are slightly softer and finer than XL Glide, which means less stipple from the cut-in showing under raking light next to the rolled field. On a flat wall paint or a satin in a side-lit room (north window, vanity light bar), the cut blends invisibly with the roll where XL Glide leaves a faint edge.

The brush is hard to find in big box. SW stores stock it, Amazon stocks it, Home Depot rarely does. Price is $25-30 for a 2.5-inch, which is more than XL Glide and roughly the same as Clearcut. For the painter who already has a Clearcut for trim and is looking to upgrade the wall brush, Black Diamond is the next step. For the painter buying their first quality brush, XL Glide is the smarter call.

White Bristle (Natural)

The pure-bristle pick for oil-based work. Hog hair, no synthetic. For BIN shellac primer, Cover Stain, or alkyd oil trim, this is the right tool; synthetic ferrule bond softens in solvent over time and the brush sheds. For everything else, skip. The line is a niche carry-over from when oil was the trim default. Purdy White Bristle pints run $18-24.

Power Lock Extension Poles

The telescoping pole system. Twist-lock collar at each joint, anodized aluminum sections, sized from 2-to-4 foot all the way to 12-to-24 foot. Pole-end thread is the standard ACME thread that fits Purdy roller frames, Wooster frames, and most third-party brush extension adapters.

Where Power Lock wins: weight. The Purdy poles are lighter than equivalent Wooster Sherlock GT by a noticeable margin, which matters over a ten-hour day rolling a stairwell or a high entry. Where Power Lock loses: the twist-lock collar slips under heavy load on the 12-to-24 footer when you’re really pushing a loaded 18-inch roller. Wooster’s Sherlock GT lever-lock holds tighter at the same length. For under 8 feet, Power Lock is the lighter and quicker pick. For exterior work or stairwells where slip is a problem, Sherlock GT is the safer pick.

Mini Rollers (Colossus, White Dove, Marathon)

Purdy’s mini-roller covers split into three lines. Colossus is the high-capacity microfiber for flat and eggshell on full walls; it holds the most paint per dip of any mini cover we’ve measured. White Dove is the woven dralon for smooth surfaces (doors, cabinet flats, panels) where Colossus would stipple too aggressively. Marathon is the budget woven cover, sold at Home Depot in 3-packs for under $10.

The frame question is separate. Purdy’s mini-roller frame is functional but the cage is harder to release covers from than Wooster’s Jumbo-Koter cage, and the Jumbo-Koter system has a broader cover selection (more naps, more lengths, more specialty options like the foam pintucks and the lambskin minis). For the cover, pick Purdy. For the frame, Wooster wins. They thread the same; you can mix the brand.

Where Purdy Wins, Where It Loses

Read across: Purdy wins on Clearcut for trim, on Black Diamond for premium walls, on the Colossus cover for paint capacity, and on Power Lock pole weight under 8 feet. Wooster wins on the Sherlock GT pole at length, on the Jumbo-Koter mini-roller frame system, and on the boutique trim category by a small margin if you prefer a softer first-stroke feel. Corona is the boutique specialty pick a step above either. Pick by tool category.

Where to Buy Without Overpaying

The 2.5-inch XL Glide sells for $17-22 across Home Depot, Lowe’s, Ace, and Amazon, within a dollar of each other. SW retail is $24, but their 30-40% off sales drop it to about $13, the cheapest you’ll see it new.

Clearcut and Black Diamond stock spottily in big box. Home Depot usually carries one Clearcut size and rarely Black Diamond. For the broader sash sizes, Sherwin-Williams stores and Amazon are the realistic channels. Clearcut runs $22-28 retail, $16-19 on an SW sale.

Power Lock poles stock at all four channels in the short and mid sizes. The 12-to-24 footer is mostly an SW store and Amazon item. Mini-roller covers are everywhere; Marathon 3-packs at Home Depot are the budget call, Colossus and White Dove are easier to find in 6-packs at SW or Amazon.

Where Kompozit Fits

Honest framing. Kompozit is our priority partner, and on brushes and applicators the answer is straightforward.

Kompozit doesn’t make brushes. Their US line is paint plus primer; the brush you put it on is your call. The cross-recommendation pairs cleanly: a Purdy Clearcut 2.5-inch for trim work with Kompozit ONE or PRO trim paint, a Purdy XL Glide for the walls. The same brush kit works for any paint brand on the shelf, which is the point of buying the better applicator. For the round-up of brushes that pair specifically with Kompozit’s line, see our best paint brushes round-up; Clearcut and XL Glide both make that list, and so does a Wooster pick we honestly think edges them in two specific cases.
