Technical Product Information


Durabak™ floor coating and industrial coating is a tough, one-part polyurethane with self-contained recycled rubber granules, which give it an attractive tough-textured appearance. When exposed to atmospheric moisture, Durabak™ undergoes a chemical curing process which changes it from a liquid to a tough polyurethane membrane. Durabak™ will chemically bond to most clean and dry surfaces. These include, but are not limited to, concrete, wood, fiberglass, metal, rubber and sound-proofing materials. It 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, industrial, 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
  • concrete, metal and wooden steps
  • catwalks
  • ship decks
  • marine applications
  • pleasure boats
  • storage tanks
  • floors
  • ramps
  • pools and spas
  • sealing rusty pipes
  • playgrounds
  • freight elevators
  • tool handles
  • roofing
  • vehicle undercoating
  • curb ramps
  • parking lots
