COLPHENE LM BARR is a single component, 98% solids, liquid applied, moisture curing elastomeric waterproofing membrane. COLPHENE LM BARR’s STPE moisture cure technology forms a continuous, tough elastic seal to the substrate that withstands extreme low and high temperatures without cracking or softening. COLPHENE LM BARR is ideal as positive-side waterproofing for concrete foundation walls and plaza decks, as well as between slab, planters, green roofs, equipment wells, and other underground construction. COLPHENE LM BARR can also be used on wood substrates like wood balconies and plywood decks.

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.
