Flaking Paint - Zinsser Primers - Gardz vs. Peel Stop
My drywall has 40 year old builder's paint flaking off underneath a 30 year old paint job.
I'd come across Gardz a year or so ago and thought I understood it to lock down old flaking paint surfaces. I now see they have a product called Peel Stop and wonder if I used the wrong product. The wording on the Gardz specs doesn't specifically say flaking peeling paint. Its wording could be interpreted as damaged drywall only, I think.
Does anyone know if there is a significant difference between the two?
- I see Gardz says acrylic resin, Peel Stop says vinyl resin.
- Gardz says hard and moisture resistant. Peel Stop says it breathes and notes it is flexible.
- Solids are slightly different. Coverage and dry time are not exactly the same.
