Durabak Adhesion Test

Print Application

Before applying Durabak, always do a small test for adhesion:

• Clean surface thoroughly with a non-chlorinated detergent.
• Roughen surface with 40-grit sandpaper
• Wipe with Xylene or Solvide
• Once completely dry, apply 1st coat of Durabak
• Once touch dry (normally 1-2 hrs), apply 2nd coat of Durabak
• Let dry for a couple of days.
• Take a screwdriver and try to peel the Durabak off the surface. (The Durabak isn’t fully cured yet, so you should be able to get under it).
• If it comes up in small pieces, you have a good bond.
• If it comes up in sheets, you need to prime with something compatible with the substrate, and which can be overcoated with a polyurethane.
• Repeat the adhesion test with the new primer.
