Quantum UV Clear Urethane Varnish’s self-sealing formula and rich, amber color gives brightwork a level, mirror-like finish with no lap lines or brush marks without thinning, in fewer coats, and with little or no sanding in between coats.


This high build, high solids finish fills the grain in three to four coats, letting you easily achieve what used to take twice as many coats: a glassy, flexible finish that’s highly resistant to weather, chemicals, and abrasion. Its unique properties create durable chemical bond that pushes water out of the wood.


  • To apply by spray, mix with Quantum Urethane Spray Activator
  • To apply by brush or roller, mix with Quantum Urethane Brushing Activator (sold separately)
  • Available in satin and gloss finishes in quart and gallon sizes
