SOPRASEAL® LM 204 VP SKU: A506
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 nap roller or a paint brush may also 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.

Fourth Avenue Junior High School – Yuma, Arizona
The building that the Fourth Avenue Junior High resides in was built in 1920 and was named a National Historic Landmark in 1982. When the building required a re-cover roof project, its National Historic Landmark status and student safety was top priority. Due to its history and age, care needed to be taken when completing the project. The products installed were required to be odor-less and could not damage the building. A second requirement for the project was that it be completed quickly and without lingering odors, because they planned to complete the installation over their holiday break. This is where SOPREMA products came into play.
