Senershield-VB
Senershield-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. Senershield-VB can be applied in temperatures as low as 25°F (-4°C) and rising.
It provides excellent secondary moisture protection behind most wall claddings including EIFS, stucco (slip sheet required), brick, siding and metal panels.
