Figure A-40. High severity patch.
(3) Measuring procedure. Patching is measured in square feet of surface area. However, if a single patch has
areas of differing severity levels, these areas should be measured and recorded separately. For example, a 25-square-
feet patch may have 10 square feet of medium severity and 15 square feet of light severity. These areas would be
recorded separately.
