Enduro Water-base polyurethane varnis

Enduro-Var is a self crosslinking polyurethane that looks more like an oil varnish than a water coating. It ambers slightly with durability suitable for residential projects, and is both sprayable and brushable. This is a good product for residential projects such as cabinets and millwork.  Enduro-Var ADHERES WELL only over WATER STAINS, DYE STAINS, and RAW WOOD. Use Enduro-Var over any other surfaces at your own risk. It will adhere over an oil stain ONLY IF the stain is completely dry (minimum 4 days drying). Available in Flat, Satin, Semi-gloss and Gloss.

  • Will Enduro-Var amber walnut or cherry if you are not going to stain it? Yes, it departs a warm amber tone, and brings out grain definition as a traditional solvent urethane would. Works great on exotic woods such as paduk, cocobolo, and bubinga.
  • Can I use Enduro-Var for finishing my stairs and floor? Yes it’s extremely durable and its origin is the gym floor industry.
  • What is the difference between Enduro-Var and High Performance? Biggest difference is Enduro-Var ambers and High Performance is water white with no amber. Enduro-Var is a modified urethane with no acrylic and is slightly more durable, chemical and water resistant. High Performance is a combination of urethane and acrylic and is durable enough for most interior projects.
  • Can I use shellac under the Enduro-Var? No, if you need to lock in dye, use only one light coat, dewaxed, 1# cut, and sand before applying for adherence.
  • Can I tint Enduro-Var to add color to my project? Yes, Enduro-Var can be used as a toner. Add 5% of any of General Finish dye or RTM stain, which will enhance the color tone. Amber or Vintage Cherry work great or a 50/50 combination of both, for a deep oiled look. Two coats will give you even more color and depth.
  • Can I use the Enduro-Var over oil base stains? Yes, Enduro-Var can be applied over any dried stain. For standard oil base stains 24-48 hour wait time, water base stains and dyes two hours. Not recommended over linseed oil or danish oils.
  • How do I apply the top coat with out getting any bubbles or overlaps? Apply liberally to ensure workability. Brush on using full, wet coats of finish with long, overlapping strokes. Do not over work this product, it starts drying right away. Catch a missed area on the next pass. If you are doing large areas such as tables or doors, use a Handi-Painter applicator, spray or use a larger brush, and keep a wet edge.
  • Can I use Enduro-Var for exterior applications? No, it is not exterior rated. Exterior 450 is our exterior rated acrylic finish.
