Finestop VB
Finestop VB is a one-component fluid-applied vapor impermeable air/water-resistive barrier. Waterproof and resilient, it may be spray-, roller-, trowel-, or brush-applied directly to approved wall substrates. It provides excellent secondary moisture protection behind most wall claddings including EIFS, stucco (slip sheet required), brick, siding and metal panels.
