DURABAK™ Spec Sheet





DURABAK™ is a tough, single-pack, totally flexible, slip-resistant, waterproof protective polyurethane coating with self-contained recycled rubber granules for an attractive tough-textured finish. When exposed to atmospheric moisture, DURABAK™ undergoes a chemical curing process which changes it from a liquid to a tough polyurethane membrane. It has excellent abrasion and chemical resistance. It is also available in a smooth version without the rubber granules.

Both DURABAK™ (aromatic version) and DURABAK 18™ (aliphatic version) may be used for indoor and outdoor applications. However, as DURABAK™ may experience some degree of fade in outdoor applications, DURABAK 18™ is recommended for maximum UV protection under these conditions.

For enhanced UV protection, DURABAK™ may be topcoated with COTE-L'S rejuvenator. Call COTE-L Industries for more information.

DURABAK™ will chemically bond to most clean and dry surfaces. These include, but are not limited to, concrete, wood, fiberglass, metal, rubber and sound-painted materials. Some metal and extremely porous surfaces may need to be primed. DURABAK™ can be applied by roller, brush or spray. DURABAK™ can give a relatively smooth or rough surface, depending on application technique.


DURABAK™ has many applications for commercial, military and civilian use. DURABAK™ protects surfaces from foul weather elements and harsh chemicals, while creating a non-slip surface on:

pedestrian walkways/truck beds/ramps and loading docks/bridges/metal and wooden steps/catwalks/ship decks/marine applications/pleasure boats/storage tanks/floors/handicap ramps/pools and spas/sealing rusty pipes/playgrounds/freight elevators/tool handles/roofing/vehicle undercoating/curb ramps/parking lots
