COLPHENE® LM BARR SKU: W7526

COLPHENE® LM BARR is a single component, 98% solids content, liquid-applied, moisture-curing elastomeric waterproofing membrane. COLPHENE LM BARR features a STPE moisturecure technology, forming a continuous, tough elastic seal to the substrate. The seal can withstand extreme cold and high temperatures without cracking or softening. This waterproof membrane for roofs is an ideal positive-side waterproofing for sealing foundations. Other uses for COLPHENE LM BARR include slab waterproofing, equipment wells and other underground construction. In above-grade applications, COLPHENE LM BARR can be used to waterproof planter boxes, sealing parapets, plaza decks and green roof systems.

Installation

COLPHENE LM BARR should be used in temperatures above 35° F (2°C.) Maintain COLPHENE LM BARR materials above room temperature before applying. Remove all dirt, oil, loose paint, water, frost and other contamination that can interfere with bonding. Form release residue and lime should be power washed and allowed to dry. COLPHENE LM BARR may be applied to green concrete without outgassing. Although concrete cure times may vary with temperature, for optimum bonding, cure time should be three to seven days. Application surfaces must be dry the touch and free of obvious moisture. See SOPREMA’s installation guides for more information on applying COLPHENE LM BARR.

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.

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.
