I bought it from a web site called improvements. It can be found at: http://www.ImprovementsCatalog.com Here is the item from the catelog:
Krack-kote™ Crack Repair (# 157056) $11.99
First Latex Krack-kote™ with Tuffglass™ fabric "bridges over" unsightly cracks , but unlike crack "fillers", this repair won't loosen and fall out. It's a pliable, permanent repair for interior walls and ceilings, and it's invisible under paint or wallpaper. Brush on coat #1, apply fabric, then brush on coat #2; paint in less than two hours! No sanding. For any plaster, drywall or concrete surface. Includes 1 pt. Krack-kote™, 3-1/2"x18' long fabric roll, and applicator. It works great!
