SOPRASEAL LM 204 VP is a one-component, 98% solids content, liquid applied, vapor-permeable air barrier membrane used in wall construction. SOPRASEAL LM 204 VP is STPE technology that has excellent freeze-thaw characteristics and superior curing in low relative humidity and low temperatures. SOPRASEAL LM 204 VP doesn’t shrink and requires less wet film to achieve dry film thickness. This moisture curable hybrid material is a non-flammable vapor permeable air barrier, which provides moisture protection behind wall claddings such as brick, siding, metal panels, EIFS and stucco. Utilization of a drainage plane is required for stucco cladding.

Installation

SOPRASEAL LM 204 VP can be applied down to 25°F (-4°C) without the use of additional additives. The most effective application method utilizes spray equipment but a 3/4” (19mm) nap roller or a paint brush may be used. Once the application is complete, inspect the wall for any light areas, blisters, holes or areas that need attention. Please refer to SOPREMA specifications and installation instructions for additional application guidelines prior to use.

Holiday Inn Express – Medina, Ohio

SOPREMA®’s SOPRASEAL® Stick VP self-adhered vapor-permeable air barrier membrane was installed to ensure a continuous air barrier with no moisture infiltration for this wall assembly requiring a “breathable” characteristic. It creates a solid barrier against air infiltration and exfiltration, which minimizes associated energy loss and condensation problems.

University of Oregon Residence Hall – Eugene, Oregon

With a student population of over 24,000, the University of Oregon was in need of a new residence hall. When selecting an air barrier for the project, it was decided that SOPRASEAL® Stick VP and SOPRASOLIN® HD would be applied.
