Print Application

Equipment

  • Short nap roller, like a 3/16” mohair or 1/8" foam
  • 100 grit Sandpaper
  • Xylene (Xylol) OR Solvide (In CA or UT)
  • Stir stick or electric paint mixer
  • Roller Tray
  • Cloth or sturdy cotton rag
  • Paint Gloves
  • Household non-chlorinated detergent, like Spic n Span
  • 3M Blue tape (Optional)
  • Paint Respirator (Optional)
  • 3M Blue tape 
  • Paint Respirator (Recommended, or at least filtered mask)
  • Rust Converter (If applying over rust)
  • Metal Etch Primer (If applying on bare metal)

 

Surface Prep

  • Clean the surface thoroughly, with a non-chlorinated household detergent
  • Rough up the surface with 100 grit sandpaper
  • Wipe down the surface with xylene or Solvide on a cloth and once completely dry, apply the Durabak.
  • IF you scuff the surface all the way down to bare metal you will need to scuff bare metal 40 grit and spot prime it with Zinc Phosphate - DO NOT USE Xylene on bare metal - wait 24 hrs between priming and Durabak application

Application Process

  • Do not open can until surface is prepped and ready to go.
  • Then open can and stir well.
  • Pour a portion into a roller tray and begin application.
  • Roll on first coat using a short nap roller.
  • Use a paint brush in corners and hard to reach areas.
  • Stir occasionally while working with the product.
  • Keep lid on can while not in use.

Coverage

1 gallon of smooth Durabak covers roughly 75-80 square feet in our standard 2 coat application.

Good to Know

  • Durabak begins to cure with exposure to air, so minimize exposure to air while working with it.
  • The consistency of the Durabak should be runny, as it’s self leveling. If it’s thicker, you can add up to 15% xylene to thin it. It should be mixable after adding the xylene and back to a runny form. If it’s pasty and thick, DO NOT APPLY, rather reach out to us for assistance.
  • You will have a few hours of work time once the can is opened (3 to 5 hours normally).
  • A second coat can be applied within 1-2 hours, once the first coat is touch dry.
  • After second coat is applied allow 24 hours before walking on it. Complete cure is about 5 or 6 days, so no heavy use until then.
  • When applying Durabak it is important to ensure that each coat does not get too thick. If Durabak is applied in a coat that is too heavy it will trap the curing gasses and leave pinholes which will eventually lead to discoloration in the Durabak.

  • Be sure to apply moderately thin coats of the Durabak and as a guide you should be getting coverage similar to what is laid out above.

Additional Tips

  • Temp should ideally be 60 degrees or above for the application, and above 40% humidity.
  • Xylene should be applied immediately to clean up any misapplied Durabak.
  • If taping off, use 3M Blue tape and remove immediately after second coat is applied.
