Crystal-clear exterior protection for wood

Varathane Ultimate Water-Based Spar Urethane provides a crystal-clear shield for exterior wood, helping maintain natural grain while standing up to sun, rain, and seasonal changes.

  • Touch up exposed beams or siding where UV exposure is a concern
  • Apply to exterior surfaces on appliances or features that endure the elements

Application tips for best results

  • For maximum protection on outdoor projects, apply a minimum of four coats of non-yellowing poly
  • Prepare surfaces, apply evenly, and allow about 2 hours between coats in good ventilation
  • Clean tools with soap and water after use; allow surfaces to dry fully before exposure to the elements
  • Ensure proper surface cleaning and light sanding between coats for a smoother finish

Varathane’s exterior spar urethane offers practical, crystal-clear protection that helps outdoor wood projects look fresh longer.
