VersiFlex PVC - Monolithic Vs. Lacquer-Coated Top Ply

Some manufacturers of PVC roofing membranes apply a lacquer coating (approximately two mils thick) to their sheet. The stated purpose of this lacquer coating is to mitigate plasticizer loss, reduce the effects of weathering, and (initially) keep the membrane cleaner and free of biological and fungal growth. However, these benefits are short-lived because lacquer coating wears off within the first few years of exposure to the elements.
