When General Finishes first told us about this new water based urethane, to be honest, we were skeptical. However, after testing and using Enduro-Var all skepticism vanished as we realized this was not the typical water based top coat. First, Enduro-Varit uses a colored urethane resin which, like oil imparts a warm glow to wood that darkens or ages over time. Second, itâ€TMs an air oxidizing, rather than a simple evaporative, finish which means exposure to air facilitates the cure. This curing process produces an incredibly tough finish that is suitable for any interior application, including floors. Combine these two winning characteristics with the ease of water based application and we think youâ€TMll agree that there is no better finish available. If youâ€TMve been hesitant about using water based finishes, we challenge you to cast your skepticism aside and use Enduro-Var on your next project.
