Single Ply Commercial Roofing
Bituminous Commercial Roofing
SBS Adhesives and Cements
With over three decades of experience producing modified bitumen, we understand the science of formulating systems that last.
Our SBS is a premium modified bitumen engineered specifically for elasticity. It is made to withstand even the harshest environments.
SBS is the most customizable of our low-slow commercial roofing products with glass, polyester and composite reinforcements. It can be installed with the widest variety of application methods including cold applied, heat weld, self-adhered, mechanically fastened, and hot applied applications.
Adhesives & Cements
1-Part PermaFlash
Use: 1-Part Permaflash is a unique, one-component, elastomeric, liquid applied flashing material, consisting of an asphalt/polyurethane resin. It is formulated for use with Johns Manville (JM) modbit membrane products.
Type: One-part, elastomeric, liquid-applied flashing material.
Color: Brown
Features: Cures to a durable, elastomeric film and forms exceptional bonds between the modified bitumen and a variety of penetrating materials. Single component solution with no mixing required that conforms easily to various geometries or irregular shapes. UV stable, high solids (80%), low odor.
Asphalt Primer
Meets the requirements of ASTM D 41, Type II
Use: Used to prepare substrates prior to the application of hot asphalt or cold adhesives in BUR, SBS and APP modified bitumen roofing systems. Do not use Asphalt Primer as a finish coat on roofs.
Type: One-part, specification grade, penetrating priming solution.
Substrates: Compatible with concrete; gypsum; masonry; block; brick; and metal surfaces.
Color: Black Features: Low VOC and sprayable.
Bestile Utility Cement
Use: To adhere both vertical and horizontal roof flashing surfaces. Useful for repairing leaks in metal, shingles, concrete, flashings, gutters, around chimneys, flues, soil pipes, drains, eaves, cornices and roof perimeters.
Type: One-part, low VOC, asphalt-based trowel-grade mastic.
Features: Maintains bond during varying temperatures and weather conditions, and bonds to dissimilar materials. Excellent Durability. Remains Flexible Over Time.
Color: Black
DynaSet 1K
Use: For adhering SBS membranes to approved substrates.
Type: One-part, solvent free, moisture curing, elastomeric adhesive.
Color: Black/Brown
Features: A solvent and odor free, single component adhesive with no mixing required. Low VOC content suitable for use in VOC regulated markets. Cures with ambient moisture to an elastomeric solid that remains flexible to absorb dynamic stresses.
JM One-Step Foamable Adhesive
Use: JM One-Step Foamable Adhesive is a two-component polyurethane adhesive used for attaching insulation or cover boards to the roof deck or to other insulation boards.
Type: Two-part, cold application insulation adhesive.
Substrates: Compatible with the following insulations, cover boards, and substrates1 : polyisocyanurate; HD wood fiber; perlite; Invinsa® Roof Board; gypsum; concrete2
(Lightweight structural, poured-in-place structural, precast, and insulating); treated plywood (5/8" [1.58 cm] min. thickness); cementitious wood fiber plank; base sheets; gypsum; and some existing smooth-surfaced asphalt (per inspection).
1. Ensure that all insulation boards are 4' x 4' or smaller.
2. Drying time of 28 days required
Color: Part 1 - Tan, Part 2 - Colorless
Features: Solvent free. Set boards immediately into adhesive; reduces installation time and maximizes adhesive footprint. No hoses or pumps required. Always on ratio, eliminates guesswork.
JM Roofing System Urethane Adhesive - RSUA
Use: JM Roofing System Urethane Adhesive is a two-component polyurethane adhesive used for attaching fleece-backed single ply membranes to insulation boards or various deck types as well as insulation boards to the roof deck or to other insulation boards.
Type: Two-part, cold application insulation adhesive.
Substrates: Compatible with the following insulations, cover boards, and substrates1 : polyisocyanurate; HD wood fiber; perlite; Invinsa® Roof Board; gypsum; concrete2 (Lightweight structural, poured-in-place structural, precast, and insulating); treated plywood (5/8" [1.58 cm] min. thickness); cementitious wood fiber; gypsum; smooth or granulated BUR, APP or SBS.
1. Ensure that all insulation boards are 4' x 4' or smaller.
2. Ensure that the concrete is adequately dry for adhesion.
Color: Part 1 - Tan, Part 2 - Colorless
Features: Solvent free, and HCFC or CFC free. Universal adhesive for adhering fleece-backed membranes and insulation boards. Sets in minutes.

Installation Instructions for JM Roofing Systems Urethane Adhesive (RSUA)
MBR Bonding Adhesive
Use: For applying SBS cold applied membranes and insulation/ cover board. Used as a direct substitute for hot asphalt.
Type: Two-part, solvent free, elastomeric, cold application adhesive.
Color: Black to Brown
Features: 100% solids with no volatile organic compounds (VOCs). Low odor and fast set time. Can be applied over wide temperature and humidity ranges. High strength with exceptional wind uplift performance. Ideal for those applications where hot asphalt is prohibited, not desirable or not practical.
MBR Cold Application Adhesive
Meets the requirements of ASTM D 3019, Type III, Grade 2.
Use: For adhering roofing plies, modified bitumen membranes and for aggregate surfacings. It can be used as a direct substitute for asphalt in all JM modified bitumen roof membrane specifications.
Type: One-part, elastomeric cold application membrane adhesive.
Color: Black
Features: Cures to form a durable, elastomeric and watertight film. Cold process – does not have to be heated. Ready for use as shipped.
MBR Flashing Cement
Use: For use with JM BUR and SBS membrane products. It is part of the JM PermaFlash® Bituminous Flashing System for penetrations and other details. Ideal for areas where hot asphalt is prohibited, not desirable or not practical.
Type: Two-part, elastomeric, liquid-applied flashing material.
Color: Black
Features: Cures to a durable, elastomeric film and forms exceptional bonds between the modified bitumen and underlying substrate. Resists virtually all factors affecting base flashing performance while providing superior flexibility and durability. UV stable, high solids, low odor, VOC compliant.
MBR Utility Cement
Meets the requirements of ASTM D 4586, Type I
Use: As a substitute for asphalt and MBR® Flashing Cement in JM modified bitumen flashing details, and can be used to adhere the JM modified bitumen flashing systems and built-up roofing felts to vertical surfaces, as a general purpose mastic on most built up roofing and modified bitumen flashing details, or to strip in the laps of modified bitumen base flashings.
