Enduro-Var Water Based Urethane Topcoat

Enduro-Var wood finish is a self-crosslinking, oil-modified, water-based polyurethane that looks more like an oil varnish than a water coating. It ambers slightly, is highly water resistant, and is both sprayable and brushable. Enduro-Var water-based topcoat adheres well ONLY over WATER STAINS, DYE STAINS and RAW WOOD. Use Enduro-Var over any other surfaces at your own risk.

Instructions

Step 1: Preparation

All wood projects require preparation sanding. If you skip this critical step, your finish may fail.

Preparation for Raw Wood or Raw Wood Projects That Are to be Stained 
See our video: How to Prep Sand Raw Wood

  1. Sanding Schedule: 120-grit followed by 150- or 220-grit sandpaper.
  2. Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.
  3. Let dry completely before applying GF product.
  4. Do not over-sand with fine-grit sandpapers; this will close and seal the wood grain, preventing ideal color absorption.
  5. 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.

Step 2: How To Apply General Finishes Enduro-Var

How to Apply General Finishes Enduro-Var Water Based Topcoat 

General Finishes Enduro-Var is an oil-modified water-based topcoat and ONLY ADHERES WELL OVER WATER-BASED STAINS, DYES AND RAW WOOD. It will adhere over 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.

  1. Stir topcoat to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
  2. Enduro-Var has a slight pink cast to the color in the can. This is normal.
  3. 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. 
  4. 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.
  5. 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.
  6. Finish sand between coats with a fine-grade (220-320) foam sanding pad to improve smoothness and adhesion.
  7. Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.

Cure Time
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.

Enduro-Var Ambers
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.

High-Use Surfaces
General Finishes High Performance Topcoat, General Finishes Enduro Clear Poly and General Finishes Arm-R-Seal Topcoat are recommended on high-use surfaces such as kitchen tabletops, kitchen cabinets or bath vanities instead of Enduro-Var because they have greater water and chemical resistance. 

WARNING: Incompatible Products

  • 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.
  • Shellac
  • Linseed Oils
  • Danish Oils

Cleanup of Water Based Products

Application tools and materials containing water-based products can be cleaned with soap and water or GF Brush & Gun Cleaner immediately after use.

Product Spills
Spills may be able to be removed from fabric and carpet if cleaned immediately with soap and water.

Storage of Water Based Products

Life of Product
Water-based products do not last forever, even when unopened. General Finishes products are best used within 1 year of the manufacture date listed on the bottom of the can. The life of the product may be extended with proper care and storage.

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 paint, use 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.

Storage Tips
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:

  1. 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. 
  2. Keep lid closed while working. Pour what you will use into a bowl, paper cup, or plate, and close can lid as you work.
  3. Clean the chime of the can thoroughly with a paper towel before closing to create a complete seal. Paint in the chime can be minimized by using a pouring lid, such as Fitsall. Avoid wiping used brushes on the lid.
  4. 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.
  5. Store in moderate temperatures. Avoid temperatures below 50°F/10°C or above 80°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.
  6. 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. 
  7. 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:

  1. Product thinned with up to 15% General Finishes Extender or General Finishes Accelerator can be stored, with the exception of thinned General Finishes Water Based Wood Stain.
  2. Mixtures involving colors & sheens within the same product line, such as:
    • High Performance Satin + High Performance Gloss
    • Snow White Milk Paint + Coastal Blue Milk Paint
    • Amber Dye Stain + Merlot Dye Stain

The following product mixtures should NOT be stored:

  • Any water based product with thinned tap water; water often contains bacteria that will adversely affect stored paint.
  • Topcoat + Stain or Paint
  • Milk Paint + Chalk Style Paint
  • Water Based Wood Stain + Dye Stain

Furniture Care and Maintenance

Cure First
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.
  • 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.

FAQs

Enduro-Var FAQs

What is the difference between professional Enduro Clear Poly and High Performance Topcoat?

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.

How do I repair a section that I have buffed through using Enduro-Var over an epoxy on a guitar

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.

Why does Enduro-Var clog up in my spray gun during use?

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.

*How Can I Tell if a Water Based Topcoat is Dry?

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.

*How to Spray Water Based Finishes

General Finishes water-based products can be sprayed through compressed air, HVLP, airless or C.A.S. units.

SURFACE PREPARATION:

All surfaces should be clean and free from dirt and oil and sanded.

Indicated below are instructional videos we have for preparing a surface for a new coat of paint or finish:

SPRAY APPLICATION OF GENERAL FINISHES WATER BASED FINISHES:

All General Finishes water based topcoats and wood stains are ready to spray from the container without additives with the exception of Conversion Varnish. Always strain material through a medium to fine mesh filter before spraying. If necessary, in hot or dry climates, reduce 10 to 15% with General Finishes Extender to extend the open time.

PRE SEALING:

Softwoods such as Pine absorb stain at an uneven rate and may respond better to staining if the wood is pre-sealed. General Finishes Pre-Stain Conditioner Natural can be applied to raw wood to condition the surface for uniform penetration of the stain. Pre-sealing will cause the final stain to be lighter so you may need to use a darker color. Always test your color on a hidden part of the furniture. Allow the Pre-Stain Conditioner to dry 30 minutes before applying your final stain color.

If you are using a sprayer that has been used for oil based or lacquers, clean the unit thoroughly with acetone followed with hot water to purge the fluid passage. Apply a thin coat first that will dry and harden faster. Sand this first coat down to a smooth base on which to build your finish coats with a 220-320 grade foam sanding pad or #400-grit sandpaper. It is better to spray 2 thin coats rather than 1 heavy coat.

Contact your supplier to verify proper tip sizes for your specific equipment. GF's general recommended fluid tips for Wood Stains and Top Coats are Compressed air - .040 and Airless - .009. 

RECOMMENDED TIPS FOR GENERAL FINISHES PRODUCTS USING HVLP:

  • Milk Paint: 1.8mm-2.0mm
  • Chalk Paint: 1.8mm-2.0mm
  • Stain Blocker: 1.8mm-2.0mm
  • Pearl Effects: 1.8mm-2.0mm
  • Glaze Effects: 1.8mm-2.0mm
  • High Performance Topcoat: 1.1mm-1.3mm
  • Flat Out Flat Top Coat: 1.1mm-1.3mm
  • Enduro-Var  1.1mm-1.3mm
  • Water Based Wood Stain: 1.1mm-1.3mm
  • Water Based Dye Stain: 1.1mm-1.3mm
  • Exterior 450 Topcoat:1.1mm-1.3mm
  • Exterior 450 Stain: 1.1mm-1.3mm
  • Enduro Sanding Sealer: 1.3-1.4mm
  • Enduro White Poly: 1.3mm-1.5mm
  • Enduro Black Poly: 1.3mm-1.5mm
  • Enduro White Under Coat 1.5mm-1.8mm
  • Enduro Clear Poly: 1.1mm-1.3mm
  • Enduro Pre Cat Lacquer: 1.1mm-1.3mm
  • Enduro Conversion Varnish: 1.1mm-1.3mm

Air caps should be medium size. Contact your supplier to verify proper tip sizes for your specific equipment.

Break your work into sections such as dresser top or drawer fronts. Spraying too large of an area can result in a textured grainy surface. A correctly sprayed finish should appear even and glossy. It is important to spray enough material to allow proper flow and leveling of the finish.

Spray medium wet films at 3-5 wet ml thickness. Practice makes perfect. If you have never sprayed finishes before, take a large piece of cardboard and practice your technique first. Spray water on the cardboard to learn how the gun works. Check your fluid settings and adjust the controls to get comfortable with the spray angles and to develop your technique.

SPRAYING TOPCOATS:

Keep your gun at a 90* angle, 6-8" from the surface. On large flat areas, use wet, even patterns 6 to 8 wide. For narrow surfaces, reduce the fan pattern to 2-3" to reduce overspray. For topcoats, overlap each pass 25% to conceal lines.

Watch our video how to spray water based topcoats here.

SPRAYING WATER BASED WOOD STAINS:

Keep your gun at a 90* angle, 6-8" from the surface. On large flat areas, use wet, even patterns 6 to 8 wide. For narrow surfaces, reduce the fan pattern to 2-3" to reduce overspray. Overlap each pass of stain 50% for even coverage and wipe back the excess with an absorbent cloth. For narrow surfaces, reduce the fan pattern to 2-3" to reduce overspray. 

SPRAYING WATER BASED DYE STAINS:

Keep your gun at a 90* angle, 6-8" from the surface. On large flat areas, use wet, even patterns 6 to 8 wide. For narrow surfaces, reduce the fan pattern to 2-3" to reduce overspray. Overlap each pass of stain 50% for even coverage. If coverage is even, there is no need to wipe. If you have issues with uneven coverage, wipe back the excess with an absorbent cloth. For narrow surfaces, reduce the fan pattern to 2-3" to reduce overspray.

Can General Finishes Water Based Top Coats Be Tinted?

All of General Finishes water based topcoats can be tinted to create lightly colored finishes for toning. Toning is the process of adding colorant, either dye or pigment into a top coat and then applying over an entire piece in order to subtly deepen the color.

Some tinting recommendations are:

  • Do not exceed 13 ounces per gallon. Excess amounts of colorant can create surface defects and decrease the viscosity (causing drips, sag, etc.).
  • Tinting a product black only requires about 6 to 8 ounces (based on strength of colorant).
  • Check for colorant compatibly (best to use a zero VOC colorant).
  • Tint off whites with white bases.
  • Enduro-Var top coat cannot be tinted white.
  • GF top coats can also be tinted with General Finishes Dye Stains or Trans Tint Dyes available at many woodworking and paint stores. This produces a transparent tinted finish. Normal addition is usually 2-5% by volume.

GF does not manufacturer colorants. Here are a few sources:

  • Mixol available at Woodcraft
  • Gennex by Benjamin Moore
  • Colortrend 896 or 888, 878

Which Topcoat Should I Choose?

General Finishes Water Based Topcoats:

  • High Performance
  • Flat Out Flat
  • Enduro-Var
  • Enduro Professional Topcoats (Enduro Clear Poly, Enduro Conversion Varnish, Enduro Water Based Laquer)

General Finishes Oil Based Topcoats

  • Arm-R-Seal Liquid Oil Based Topcoat
  • Gel Satin Topcoat

GENERAL PRACTICE:

  1. Oil based topcoats and Enduro-Var will amber over time.
  2. Water based Flat Out Flat and High Performance top coats dry clear.
  3. Never use any water based topcoat with long oils such as Danish, Tung or Linseed.
  4. Water based top coats clean up with water. OIl based topcoats require mineral spirits for clean up.
  5. Enduro-Var ADHERES WELL only over WATER STAINS, DYE STAINS, and RAW WOOD.
  6. If you use water based topcoats over oil based finishes, make sure that you wait 72 hours between the two products. It is essential to let the oil finish dry longer.
  7. Large/Detailed Surfaces - For more complex projects that have a lot of nooks and crannies or projects with large surface areas such as cabinets, we recommend either ARM-R-SEAL liquid oil based topcoat or any of our water based topcoats.
  8. Enduro Professional Top Coats are thinner and intended to be sprayed
  9. High Performance and Flat Out Flat can also be sprayed. If needed, it can be thinned by adding 10% water or Extender. Large surfaces such as cabinets or tables and complex projects with lots of detail are easier to cover with liquid top coat rather than a Gel top coat.
