What Customers Are Saying

Most customers praise this product for bonding flaking paint and creating a stable base for topcoats, especially on deteriorated ceilings, trim, and old surfaces. However, many report it applies much thinner than the "triple thick" marketing suggests, requiring three to four coats for minimal coverage and comparing it to skim milk. Some experience chipping or poor adhesion despite careful application, while others note high cost relative to performance. A few find success with proper surface preparation and multiple coats. Overall, reviewers are divided between those who credit it for enabling successful repaints and those disappointed by thin consistency and coverage shortfalls.

After reading the review from a professional that explained what the product did, I knew it was what I needed for my project. This primer worked great at hiding and adhering the flaking paint on my chimney!

This Product under your Paint makes it look better

Would Recommend

I have now completed 3 wood painting projects on the siding of my house using this primer. The condition of the siding was bad to worse tounge and grove. Sanding was not going to work. Border line replacement was over the top expensive. I was told about Z-Peel Stop. Caulked the cracks and gaps. Painted on 2 thick layers of this product then painted and “Bam !” it looks so so Good. You won’t be disappointed.

Talk about buyer’s remorse!

Would Not Recommend

First, I’ve used this brand many times in the past and been well pleased. So when beginning work on a huge wrap-around porch on historical home, I didn’t hesitate buying this brand again. Something to prevent peeling as well as helping to fill uneven surfaces? No brainer, I thought. As the porch floor has a gray-blue floor, I opted to have some tinted gray. After spending days of scraping, sanding, and more scraping, started applying this primer. On opening the non-tinted primer, it appeared b...

Had some bubbling issues, otherwise a nice primer

Would Recommend

We used Peel Stop on our old 1950 garage that has clapboard siding. It was freshly painted by the previous homeowners 3 years ago and that paint had begun to peel badly all over. We scraped everything down and then applied Peel Stop to the entire exterior. For the most part it went well - it seemed like the areas where my husband painted it on really thick bubbled by the next morning. Areas where I painted it on much thinner seemed to do better. We scraped down those bubbles and recoated in a th...

Perfect for helping refinish a peeled surface

Would Recommend

Used this product on an exterior door that hadn't been finished correctly and the paint had bubbled in multiple spots. Sanded those spots back, hit it with this peel stop, then some filler to smooth out the surface before a light sand and then refinishing with paint.

It’s like I didn’t prime at all

Would Not Recommend

I noticed this didn’t seem to be covering very well as I applied it, so I made sure to paint it on generously. The next morning, it looks like the wall wasn’t even primed at all. Talk about a waste of money and time.

Prevented me from having to start over

Would Recommend

I’m not a professional so I probably did something wrong to get to where I was but this stuff saved my project. I’m repainting wainscoting and had to replace all of the old caulking. It took me over a month just to remove and replace the caulk because there was so much of it. It was all finally done and I let it cure for a few days just to be sure, then I primed everything. Immediate cracks on every inch of the Premium Molding & Trim Acrylic Latex Siliconized Sealant. I was devastated. A layer o...
