For roofing contractors installing SBS modified bitumen or conventional built-up roofing systems, achieving a strong, flexible, and reliable bond between plies is essential. Del-Val 201 SBS Modified Adhesive – Brush Grade from United Asphalt is a cold-applied, SBS polymer modified asphalt roofing adhesive formulated specifically for this purpose. Its SBS modification provides enhanced flexibility and adhesion, ensuring excellent performance over the life of the roof.
Del-Val 201 is designed for use in horizontal applications to install SBS modified bitumen base and ply sheets, as well as SBS modified bitumen cap sheets. It can also be used effectively in conventional built-up roofing systems as an inter-ply adhesive. Important: This product is NOT designed for use with EPDM, PVC, TPO, or other single-ply membranes, nor is it compatible with modified membranes that have a polyolefin film.
Proper preparation is crucial for optimal adhesion. All surfaces must be clean and free of any oil, grease, dirt, and all other foreign matter. Any problem areas, holes, cracks, blisters, tears, or breaks should be repaired beforehand with Del-Val 212 SBS Modified Flashing Cement – Trowel Grade. Metal surfaces must be free of all rust. Apply Del-Val 201 to a clean, dry surface using a brush or notched squeegee. Spread the product uniformly, taking care to avoid heavy mounds of mass accumulation. It is critical that all membranes are fully adhered in position before the adhesive sets. For best results, press the sheets with a heavy roller after they are in place to ensure a tight bond between plies.
Coverage rates vary depending on the surface; apply at a rate of 1 to 1½ gallons per 100 sq. ft. for smooth surfaces. On porous surfaces, a rate of 2 gallons per 100 sq.ft. may be required to ensure adequate coverage and bond. Clean tools with Del-Val Orange Cleaner & Degreaser or mineral spirits. This product meets or exceeds the requirements of ASTM D-3019 Type III, confirming its quality and suitability as an SBS modified asphalt roofing adhesive.
