What Customers Are Saying

Customers overwhelmingly praise this primer for exceptional stain-blocking coverage, fast drying time, and ease of application. The water-based formula delivers strong hiding power on dark colors, bold surfaces, and challenging materials like OSB and stained wood. Many highlight quick dry times that keep projects on schedule, smooth application, and effortless water cleanup. Reviewers appreciate its versatility across drywall, wood, and exterior surfaces, with numerous mentions of intent to repurchase. A few note multiple coats work best on heavily stained areas, and some detect faint odor, though most find it minimal compared to alternatives. Overall, customers consider it a reliable, high-performing choice.

Great Coverage

Would Recommend

Got this tinted in grey 2 and paired it with 1/2” & 3/8” nap rollers. The 1/2” roller really helped hide damage on the drywalls and the second layer using the 3/8 made for a nice smooth base for the paint.

Wall panel

I like how easy it was to use. It says it has a 30min dry time but i feel like it was alot faster then that. Maybe bc i was painting wall paneling.

don't even try to spray

Would Not Recommend

Tried to filter, wouldn't filter - should have taken the hint. Tried to spray(graco magnum) and it clogged every 5 - 15 seconds. Spent more time trying to unclog the sprayer than spraying. Tried some leftover kils, and it sprayed fine, so not the sprayer.

I really liked how well it covered in fewer coats and how effectively it helped eliminate existing mold. This is a great choice for anyone dealing with mold-prone areas who still wants a high-quality finish. DIY users and professionals alike would benefit from it. I would have liked to know upfront how strong the coverage really is, as it could help p...
