PATCHING
Jahn Patch: Does it shrink? Oh yes it does. Cracks too.
Edison Patch: Never used it (heard it has an acrylic component) Is it
true?
Keim Patch: Tried it a little. Like the idea of its two part system
(rough underpatch to bulk up, fine thin top patch for looks).
Insufficient tech. support and service in the USA at this time. Great
potential. Mineral coatings outstanding.
Patching is a short term fix, especially over 6x6x1"
