Barribond HP Sausage: Liquid Flashing & Detail Sealant

Barribond HP Sausage: Liquid Flashing & Detail Sealant

Barribond HP is a high-solids, silane-terminated polyether (STPE) based compound designed for detailing rough openings, penetrations, sheathing joints, countersunk screws, transitions, angle changes, and other critical details encountered in CCW Fluid-Applied Air Barrier Systems. BarriBond HP can also be used as a termination mastic over CCW Self-Adhered Sheet Flashing Membranes. Barribond HP is a single-component, moisture-cured adhesive/sealant which is applied from a sausage caulking gun, then smoothed in place with a trowel or squeegee. BarriBond HP is offered in a signature blue-gray color for easy identification in warranted CCW Air Barrier Systems. The product is formulated for clean, easy application over horizontal, vertical, and inverted surfaces. Questions? Contact Us.

Surfaces shall be clean of oil, dust, and sound with no excess mortar droppings. Concrete and masonry surfaces can be damp, but no standing water or frost. All other substrates shall be dry. Concrete Masonry Joints shall be free of voids and shall be tooled or struck flush. Gaps from ¼” to 1″ wide shall be fitted with backer rod. Joints receiving backer rod shall provide a sealant depth of at least a ¼” but not more than ½”. Acceptable substrates include Concrete Masonry Units, mortar/grout, concrete, exterior grade gypsum board, plywood, OSB, wood, aluminum, galvanized metal, and anodized aluminum. Any damaged gypsum sheathing should be replaced. Voids or irregularities in concrete or masonry substrates should be patched using a cementitious patching compound as needed.

Apply BarriBond HP in serpentine beads over the substrate. Spread BarriBond HP using a squeegee or a trowel to provide full, uniform
coverage over the substrate. Apply to openings, pipe/duct penetrations and inside/outside corners as shown in the respective CCW air barrier system standard details. Apply BarriBond HP at a uniform wet mil thickness of 40 mils (0.040 inch), continuously monitoring thickness with a CCW Wet Mil Thickness Gauge to assure adequate coverage. BarriBond HP can be applied  in a single coat. To facilitate installation, joints and gaps between dissimilar substrates may be treated with BarriBond HP and allowed to cure firm before proceeding with trowel coverage of the liquid fl ashing area. Also, the raw edge of gypsum sheathing can be treated with CCW-702, 702 LV, or 702 WB to consolidate this substrate and facilitate coverage with BarriBond HP. In liquid fl ashing applications, BarriBond HP shall tie into the main CCW Air Barrier Membrane with a minimum 2 inch lap. CCW BarriBond HP can be applied over all CCW Air Barrier Membranes, or the CCW membranes can be applied over BarriBond HP, depending on construction progression.
