When roofing projects involve SBS modified bitumen systems or require a flexible and elastic cement for detailing and repairs, Del-Val 212 SBS Modified Flashing Cement from United Asphalt provides a high-quality, cold-applied solution. This cement is formulated to a heavy, smooth, trowel consistency, making it easy to apply and work into challenging areas. Its key feature is the inclusion of SBS modification, which provides great elasticity, allowing the cured cement to accommodate movement and maintain a durable seal.
Del-Val 212 is primarily used for applying SBS modified bitumen membrane flashings to vertical surfaces like parapet walls and curbs, where flexibility is crucial. It is also ideal for repairing roof penetrations and for sealing laps on SBS modified roofs and penetrations on APP products, ensuring watertight integrity in these critical areas. This versatile cement is also excellent for repairing a host of other components on various surfaces, including asphalt shingles, built-up roofs (BUR), metal joints, masonry surfaces, chimneys, vents, skylights, and gutters. Important: This product is NOT suitable for use with EPDM, PVC, TPO, or other single-ply membranes.
Proper preparation is necessary for optimal adhesion; the surface must be clean and free of dirt, dust, oil or grease, and any other foreign matter. In colder climates, storing the product at room temperature for 24 hours prior to application is recommended. Apply Del-Val 212 SBS Modified Flashing Cement with a trowel or putty knife. Spread the cement to approximately 1/8″ thickness and work it thoroughly into the problem area. For repairing cracks and blisters that are 1/4″ wide to 2″ long, apply United Asphalt Cotton or Fiberglass Fabric for reinforcement then cover with additional cement. Apply at a rate of approximately 8 gallons per square (100 sq ft) per coat, though coverage may vary depending on the application. Clean tools with Del-Val Orange Cleaner & Degreaser or mineral spirits. This product meets or exceeds the requirements of ASTM 4586 Type I, confirming its quality and suitability as an asphalt plastic cement used as a flashing cement with enhanced elasticity. Important precautions include: DO NOT THIN, DO NOT HEAT CONTAINER, and Do not store in an area where temperatures exceed 120°F.
