System Three WR-LPU Waterbased Exterior Polyurethane
System Three WR-LPU is a two-part Waterbased Urethane designed primarily for exterior applications.
It is the premium topcoat (better than Spar Varnish) featured in System Three's "Clear Finishing of Outdoor Wood" project.
WR-LPU is extremely weatherable and abrasion-resistant, and will retain its appearance for long periods in a variety of environments.
It can be applied directly to bare wood, but using over System Three's Yacht Primer or Seal Coat provides the longest surface protection.
Very easy to use by brush, roller or by spraying. WR-LPU offers a Low VOC content and is thinned & cleaned up with water for convenience and safety.
While seemingly expensive, WR-LPU provides exceptional value as compared to Spar Varnishes due to it's significant protection abilities and long-life before recoating may be required.
