A Brief Comparison Table

My Experience With Sherwin Williams Shellac Primer Vs. Bin

I launched into a home refresh in February 2025, starting with a kitchen where decades of cigarette smoke had left yellow stains and a stench that wouldn’t quit. On February 5, I picked up the Sherwin Williams White Pigmented Shellac Primer, a gallon that caught my eye with its promise of stain-blocking power, and started on February 12.

The alcohol-based formula had a sharp smell that hit me hard, so I cracked every window and wore a mask while brushing it on with a 2-inch synthetic brush after a quick wipe-down. The 30-45 minute dry time was decent, and by February 13, I added a topcoat—those stains vanished, though the odor lingered longer than I’d hoped.

On February 20, I grabbed Zinsser B-I-N, lured by its reputation and faster dry time, and tackled the same kitchen area on February 27. The 20-minute touch dry blew me away, and the moderate odor faded fast with ventilation, letting me recoat in 45 minutes. Both sealed the smoke stains, but B-I-N felt smoother on the brush.

 March 10, I moved to a bathroom with water-damaged drywall—Sherwin Williams rolled on easily with a 9-inch roller, drying in 40 minutes, while B-I-N’s 20-minute dry let me rush the job, though its coverage stretched further per gallon.

 April 15, I hit a garage door with grease stains; Sherwin Williams blocked them after a light 120-grit sand, but B-I-N’s adhesion on the glossy surface outshone it, needing no extra prep.

May 5, I tested both on pet-stained hardwood—Sherwin Williams sealed the odor but left a tacky spot if I recoated too soon, while B-I-N handled it flawlessly with its quick dry.

June 3, I sprayed trim with an airless sprayer, thinning Sherwin Williams slightly, and its overspray was a mess to clean, unlike B-I-N’s smoother flow.

July 8, I tackled a knotty pine wall—Sherwin Williams showed tannin bleed after a week, needing a second coat, while B-I-N locked it down better. By July 15, after 175 days, both have held up, but Sherwin Williams’s higher cost and odor bugged me, while B-I-N’s versatility won me over. You’ll find your match as we explore further!

• Recoat Timing: The 45-minute window on February 27 felt tight if I got distracted.
