Enduro-Var II is a reformulation of our original oil-modified, ambering, water-based topcoat. It replaces original Endurovar and is made with more than 70% RENEWABLE RESOURCES formulated from sustainable materials that decrease the carbon footprint and can be used with all of GF's water-based products. The new formula dries to a lighter amber than the previous formula, is highly water-resistant, and is both sprayable and brushable. Download Professional Water Based Product catalog here.
Sanding Schedule: 120-grit followed by 150- or 220-grit sandpaper.
Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.
Let dry completely before applying GF product.
Do not over-sand with fine-grit sandpapers; this will close and seal the wood grain, preventing ideal color absorption.
Do NOT use steel wool with water-based finishes; the particles will get trapped in the finish and rust.
Preparation for Projects with an Existing Finish (Sealed Surface)
1. Completely remove existing finish prior to use.
2. Test entire finishing process over raw wood for adhesion before getting started. Contaminants from an existing finish can seep into the wood and impact results.
How to Apply General Finishes Enduro-Var Water Based Topcoat
General Finishes Enduro-Var is an ambering oil-modified water-based topcoat and ONLY ADHERES WELL OVER WATER-BASED STAINS, DYES AND RAW WOOD. Use Enduro-Var over any other surfaces including oil products, sanding sealers and shellac at your own risk.
Stir topcoat to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
Enduro-Var has a slight pink cast to the color in the can. This is normal. It will dry to a light amber color.
If desired, thin with up to 15% distilled water or General Finishes Extender. Start by adding 5% in increments until you reach the desired consistency. GF Extender will improve flow and leveling and increase open time, which is helpful in dry climates.
Apply 3 coats. More coats will not improve durability.
Hand application: Apply a liberal amount of product using a synthetic bristle brush, foam brush, pad applicator, or roller. Avoid pressure and back brushing. Wipe along the wood grain using smooth, even strokes with light lap marks.
Spray application: Before spraying, strain topcoat through a fine-mesh filter. Spray wet films at 3-5-mil thickness. HVLP: 1.1mm-1.3mm spray tip, medium air cap. Verify tip sizes with your equipment supplier. See our general guide for spray tip sizes. Keep your gun at a 90° angle, 6-8" from the surface. On large, flat areas, use wet, even patterns 6-8" wide. For narrow surfaces, reduce the fan pattern to 2-3" wide to reduce overspray. Overlap each pass 25% to conceal lines. Wear a full filter respirator (NIOSH/MSHA-approved) and work in a ventilated space. Visit this FAQ for more information on spraying techniques.
Finish sand between coats with a fine-grade (220-320) foam sanding pad to improve smoothness and adhesion.
Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.
General Finishes Enduro-Var is water-based, but it imparts a warm amber tone and brings out grain definition as a traditional solvent urethane would on exotic woods such as Paduk, Cocobolo, and Bubinga.
Tinting & Toning Enduro-Var
Add up to 5% General Finishes Dye Stain or General Finishes Ready-to-Match Stain to enhance color tone. General Finishes Amber Dye Stain or General Finishes Vintage Cherry Dye Stain work well, or a 50:50 combination of both. Apply 2 coats of the tinted topcoat for a deeper, more vibrant color.
All oil-based products. Enduro-Var ONLY ADHERES WELL OVER WATER-BASED STAINS, DYE STAINS, and RAW WOOD. It MAY adhere to an oil-based stain ONLY IF the stain is completely dry (minimum 4 days dry time). Use Enduro-Var over oil stains or any other surfaces at your own risk.
Dry Time Between Coats
Dry 4+ hours between coats in ideal conditions: 70*F/20°C; 50-70% humidity.You can tell if a water-based finish is dry if it forms a powder when lightly sanded with a fine-grade (220-320) foam sanding pad. If in doubt, wait longer.
Increase dry time if:
Humidity is over 80%
3+ coats are applied
Thick coats are applied
Applying over products from other brands
Layering General Finishes water and oil based products:
Water over oil: Let oil-based products dry 72+hr before applying water-based products
Oil over water: Let water-based products dry 24+hr before applying oil based products
To speed up drying in humid conditions add General Finishes Accelerator and work in a space with good ventilation and air movement. If you decide to re-coat before the recommended time, test dryness.
Cure Time Before Use
Water-based finishes cure and harden for full use after 21 days in ideal conditions. Avoid placing heavy objects on surfaces that have not cured completely. Treat gently, and do not clean with commercial products during the curing period.
Please be mindful of the manner in which water-based products are stored and how long they have been in storage. They not a forever product.
Life of Product
Water-based products do not last forever, even when unopened. General Finishes products are best used within 1 year. However, the life of the product may be extended several more years with proper care and storage (see Storage Tips below).
Water-based products can last 3-5 years if the can is unopened, in good condition and stored in correct temperatures.
Product that is 3 years old will not look like product that is 6 months to 1 year old. You will see more stratification or separation as the product ages. Always stir thoroughlybefore using.
If your product hasa foul smell, it is contaminated and no longer in useable condition.
Clumps & Settling
Gravity can cause some solids to settle on the bottom of the can and slight separation on the top. This is normal. If working with older product stir with a paint mixing attachment on a drill.
If the solids dissolve and clumps smooth out after mixing from the bottom, the product is in good condition for use.
Inability to reincorporate large, chunky lumps after stirring for several minutes is an indication that the product has frozen and can no longer be used.
See video tutorial: Tips on Storing Leftover Finishes
Water-based finishes crystalize and form a skin due to evaporation when the air-tight seal on a can is broken at first use. The following best practices will increase the life of your product:
Pry open sealed lids with a paint can opener by hooking under the lid's rolled edge. The use of a screwdriver can disfigure the rim and lid, impairing a complete seal.
Keep lid closed while working. Pour what you will use into a bowl, paper cup, or plate, and close can lid as you work.
Clean the chime of the can thoroughly with a paper towel before closing to create a complete seal. Product falling into the chime can be minimized by using a pouring lid, such as Fitsall. Avoid wiping used brushes on the lid.
Pound the lid in place using a rubber mallet to avoid distorting the chime or lid. Dents in the lid from direct contact with a hammer can impair a complete seal. Alternatively, place a flat piece of wood over can lid and firmly pound shut.
Store in moderate temperatures. Avoid temperatures below 50°F/10°C or above 100°F/26°C. Keep from freezing. Frozen and heat-damaged product cannot be revitalized. Temperature-controlled spaces, such as a basement, are ideal for storage. Do not store product in an attic, garage, in direct sunlight, or next to something warm like a water heater or furnace.
Store can upside down to create a liquid seal, minimize evaporation and reduce the chance of crystallization. Decant remaining product from the can before stirring.
Decant leftovers to a smaller container when the finish is almost used up. Alternative storage containers for water-based products are plastic FIFO bottles or glass bottles. Do not fill metal-lidded containers completely to prevent them from rusting.
The following water-based product mixtures can be stored:
You have just finished applying a fine furniture finish. Treat gently until the paint or topcoat have fully cured. Allow 21 days for a water-based finish to cure and 30 days for an oil-based finish to cure before cleaning.
Regular Cleaning and Maintenance
Remove dust with a water-dampened cloth. Dust can build up over time and may scratch or dull finishes if not removed regularly.
Remove fingerprints, cooking fumes and smoking residue with mild soap and water. These contaminants will not harm the finish, but they accumulate on surfaces and dull the original luster.
As with all fine furniture finishes, avoid using furniture polish, cleaners or dusting sprays that contain silicone, alcohol, ammonia and anything acidic. Exception: We have successfully cleaned with Clorox wipes for occasional cleanups.
Clean up water, alcohol and food spills in a timely manner and use placemats & coasters to protect the finish.
Future finishes or touch-ups may not adhere properly or perform as desired over a contaminated surface. Some contaminants, such as silicone, seep through finish into the wood and often cannot be removed.
Avoid excessive exposure to direct sunlight, high temperatures or high humidity. These can damage furniture and finishes.
The following products should not be used under or over Enduro-Var for ideal results.
All oil based products. Enduro-Var ONLY ADHERES WELL OVER WATER-BASED STAINS, DYE STAINS, and RAW WOOD. It will adhere to an oil-based stain ONLY IF the stain is completely dry (minimum 4 days dry time). Use Enduro-Var over any other surfaces at your own risk.

Enduro Clear Poly is designed for professionals that routinely spray their finishes. High Performance is formulated for the retail market so it can be sprayed or hand applied.
Enduro Clear Poly is slightly more durable than High Performance in the categories of wear, water, and chemical resistance.
Even though Enduro Clear poly is more durable and more water resistant than High Performance, High Performance is extremely durable and also recommended for high-use surfaces like kitchen cabinets and table tops.
Both products can be sprayed
High Performance can also be applied by hand with a foam/bristle brush.
Clear Poly is an Acrylic Urethane and High Performance is a Urethane/Acrylic Blend.
High Performance is sold in Pints, Quarts & Gallons by GF Retailers, Clear Poly is Gallon, 5-gallon pails and 55-gallon drums by GF Distributors. Cost is determined by Retailer/Distributor.
Our first concern is the use of the epoxy. Although you have may had success with this process previously, we do not recommend the use of Enduro-Var with epoxy or any oil based products. Enduro-Var works well on its own or with GFs water based finishes. There is a great possibility that future finishes can fail.
Nor do we recommend adding denatured alcohol, which should not be used in any of General Finishes water based products. Denatured alcohol can change the polarity of a finish formula, kicking out polymer particles that would look like grit on the surface. Denatured alcohol could also deactivate the defoamers in the formula.
The use of Extender won't help you. It is a water based product and will not melt through existing layers of finish in the same manner that solvent finishes do.
We interpret that you are trying to remove witness lines which are basically sanding marks. For your current situation, we recommend attempting to build the area with just Enduro-Var, then buffing out with a 2000-3000 grit. You may have to sand down and start over if that is not successful.
Future forward. Use Enduro-Var on its own. Although it is a favorite among Luthiers, it is a unique hybrid finish that does not pay well with other finishes.
Enduro-Var sprays beautifully if the gun is absolutely clean and does not have any other finish residue. Proper cleaning with acetone followed with hot water should purge the fluid passage. Enduro-Var itself will not cause gun failure.
Another possibility is the power of the gun. Some of the lower quality guns can overheat causing the product to cure in the gun - they need a rest once in a while if you are using them all day.
Also note that Enduro-Var ADHERES WELL only over WATER STAINS, DYE STAINS, and RAW WOOD.
If the finish feels cool to the touch, it's not ready. When you can sand it to a dry powder, it is ready for the next coat. Dry times will be longer if it is raining, cold, or humid. When in doubt, waiting longer is always better.
