4. Removed Everseal requirement from Pryzm Installation for light commercial/commercial install. Use only where needed.
5. Added to Pryzm Installation 6 mil polyfilm is recommended over concrete subfloor and required over high moisture concrete listed below:
Over concrete subfloors we recommend using 6 mil polyfilm moisture barrier. If excessive moisture, over 90% RH, is present or if slab moisture cannot be verified, the use of a 6 mil polyfilm moisture barrier is required. The moisture barrier should be overlapped six inches and taped at the seams.
