Enduro-Var Water-Based Polyurethane

General Finishes Enduro-Var Water-Based Oil-Modified Polyurethane

Enduro-Var II is a self-crosslinking, oil-modified, water-based polyurethane from General Finishes that delivers the warm amber appearance of a traditional oil varnish with the faster dry time and lower odor of a water-based product. It is both brushable and sprayable, making it a versatile topcoat for furniture, cabinetry, and interior woodwork.

Unlike standard water-based finishes that dry clear, Enduro-Var II ambers slightly over time, enriching the look of natural wood without the yellowing associated with oil-based alkyd finishes. Its self-crosslinking chemistry creates a tough, highly water-resistant film that holds up under everyday use.

Important Compatibility Note

Enduro-Var II adheres reliably over water stains, dye stains, and raw wood only. It is not recommended over oil-based stains, waxes, or other finish types. Always test adhesion on a scrap piece before applying to a finished project. For application guidance and finishing techniques, visit the Infinity Tools learning center.

Frequently Asked Questions

What makes Enduro-Var different from a standard water-based polyurethane?

Enduro-Var II is an oil-modified, water-based formula that self-crosslinks during cure, producing a film closer in appearance to oil varnish than typical water-based finishes. It ambers slightly rather than drying perfectly clear.

Can I apply Enduro-Var over an oil-based stain?

No. Enduro-Var II is formulated to adhere over water stains, dye stains, and raw wood only. Applying it over oil-based stains or other finish types may cause adhesion failurealways test compatibility on a scrap panel first.

Is Enduro-Var brushable or does it require a sprayer?

It can be applied both ways. Enduro-Var II is formulated for brush application and can also be sprayed with appropriate HVLP equipment for a smoother, faster finish on large surfaces.

How water-resistant is Enduro-Var once cured?

General Finishes describes Enduro-Var II as highly water-resistant, making it well suited for tabletops, kitchen furniture, and other surfaces that encounter occasional moisture. For fully exterior or submerged applications, a dedicated exterior finish would be more appropriate.

How many coats of Enduro-Var do I need?

For most projects, two to three coats with light scuff-sanding between coats produces a durable, attractive finish. Follow the manufacturer's guidelines on the product label for dry times and recoat windows. The Infinity Tools learning center also has finishing tips.

Does Enduro-Var amber over time?

Yes, slightly. The oil-modified formula adds a warm amber tone that deepens wood color similarly to an oil varnish. This is a characteristic of the product and is considered a benefit by woodworkers who want a richer, more traditional appearance.

What size is the Enduro-Var II available in?

What surface preparation does Enduro-Var require?

Sand the wood to a smooth surface, remove all dust, and apply the finish directly over raw wood or a compatible water- or dye-based stain. Do not apply over wax, shellac, or oil-based finishes without confirmed compatibility testing.

Does Infinity Tools offer a satisfaction guarantee on finishing products?

Yes. Review the Infinity Tools quality guarantee for details on product satisfaction and return policies.
