What people are looking for is NOT the 27" "NuWall" by Warner; it is 48" fiberglass "Nu-Wal" by Specification Chemicals. www.spec.chem.com
The fiberglass is 48" wide and comes in 40' and 120' rolls. You'll need the restoration coating #2500 (sold in 2 gal and 6 gal buckets) for both the top & bottom coats. If you're using it in a kitchen or bathroom, you will need the #2500 for the bottom coat and the water-proof #3600 for the top coat. (This is explained on the website & in the video.)
Make sure you order the video and watch it before you get started. Once you understand how it works, it's very easy and it goes quickly.
We've used Nu-Wal in our 1880's Victorian and we love it. The walls look almost as perfect as new drywall. It's wonderful stuff!
