FLEX-SEAL LIQUID MEMBRANE is supplied in a two part package with the contents of the activator (part B) contained within the larger base component (part A). FLEX-SEAL LIQUID MEMBRANE is available in two package sizes, 15L (3.3 gal.) and the more commonly used 5.7L (1.3 gal.).

Surface conditions and application technique will influence coverage, however typically, a 5.7L (1.3 gal.) unit will cover 10m2. As a fillet and reinforcement a 5.7L (1.3 gal.) unit will cover 7.6m. For estimating purposes expect typical usage of one 5.7L unit/10 m2 area.
