Carlisle CCW Miradri 860/861: Self-Adhering Membrane

Carlisle CCW Miradri 860/861 is a self-adhering sheet membrane consisting of 56 mils (1.4 mm) of rubberized asphalt laminated to 4 mils (0.1 mm) of polyethylene to form a minimum 60-mil (1.5 mm) membrane. The combination of these two excellent waterproofing materials provides a high-performance, extremely durable waterproofing barrier.  860/861 is suitable for installations where the ambient temperature is 40°F (4.4°C) or above. Miradri 860-861 can be used for applications between 25°F (-3.9°C) and 40°F (4.4°C) if the product is stored in a heated area until use and the laps are treated with CCW contact adhesive. Questions?

Carlisle CCW Miradri 860/861 membrane is used for vertical and horizontal waterproofing on structural foundation walls and decks. Below-grade foundation walls, tunnels, split slabs, plaza decks and parking decks are all areas where Miradri 860/861 may be applied. Miradri 860/861 also may be used in interior areas such as mechanical rooms, laboratories, kitchens and bathrooms. Miradri 860/861 should be covered with either CCW 200V/300HV Protection Course, CCW Protection Board, or CCW Miradrain drainage composites.

Temperature: Typical installation of Carlisle CCW Miradri 860/861 can be performed when ambient and substrate temperatures are 40°F and above.
Installations below 40°F are best addressed with Miradri 860 ULT (ultra low temperature adhesive formula). However, installation between 25°F – 40°F may be performed if the Miradri 860/861 is stored in a heated area until use and the laps are treated with CCW contact adhesive. Consult your local CCW Technical Representative and the Miradri 860 ULT product data sheet for further information.

Preparation: Do not apply Miradri 860/861 to frozen or wet substrates. The membrane should not be left exposed to direct sunlight for longer than 14 days. Miradri 860/861 can be applied to concrete, metal, wood, insulated wall systems or masonry surfaces. All substrates must be clean, dry and free of surface irregularities.

Concrete Substrates: Structural concrete must be cured a minimum of 7 days and lightweight structural concrete must cure a minimum of 14 days before the application of Miradri 860/861. Repair surfaces that are not structurally sound or have voids, protrusions, rough spalled areas, loose aggregate or exposed course aggregate. Any voids exceeding ¼”  in width should be filled with latex Portland cement, concrete or epoxy concrete and troweled smooth to match the existing surface. Protrusions and other rough areas should be broken off and patched as above. CCW LM 800XL, CCW 201, or CCW 703V may be used to fill small voids, honeycombs or bug holes.

Masonry Substrate: Apply Miradri 860/861 waterproofing over concrete block with smooth trowel-cut mortar joints or rough surfaces prepared with a parge coat. Allow the parge coat to dry before priming and installing the Miradri 860/861 waterproofing membrane.

Priming: All concrete, metal, masonry, wood and sheathing substrates require CCW Contact Adhesive. Insulated concrete forms require a water-based CCW Contact Adhesive. Carlisle Coatings & Waterproofing recommends an adhesion test of the Miradri 860/861 on any bare substrate to verify proper adhesion. Apply the appropriate CCW Contact Adhesive at the specified coverage rate. Apply Contact Adhesive with a lambswool roller, brush or spray apparatus. Allow Contact Adhesive to dry for a minimum of 30 minutes. The CCW Contact Adhesive will dry to a tacky finish. Areas primed with a CCW Contact Adhesive but not covered with Miradri 860/861 within the same day must be re-primed.
