Instructions

Step 1: Preparation for Raw Wood & Existing Sealed Surfaces

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

Raw wood 

See our video: How To Prep Sand New Wood

1. Sand no finer than 220 grit. 

2. Remove dust.

New Stained Surface: Do not sand. Apply directly to the stained surface.

Pre-Finished Wood & Sealed Surfaces 

See our video: How to Prepare Existing Finishes 

  1. Scuff clean with a non-woven abrasive pad & 50:50 mix of denatured alcohol & water. 
  2. Dry 1-2 hours.
  3. Sand lightly with 220-320-grit sanding sponge.  
  4. Remove Dust

Other Substrates: Interior MDF, HDF, & Masonite

Can be used with proper preparation & priming. Always test first.

Step 2. How to Apply General Finishes Enduro Clear Poly

CAUTION:  Do NOT use GF Enduro Clear Poly or any other clear coat, over white or light paints such as GF Milk Paint, or GF White Poly as it may cause yellowing. Any clear coat can become reactive over wood substrates or existing finishes causing tannin, stain or dye bleed-through. All of GF's White Paints, brushable or spray versions, do NOT require a topcoat.

General Finishes Enduro Clear Poly Spray Application: Raw Wood & Sealed Surface
  1. Watch product overview video here or comparison of GF water based topcoats here.
  2. Work in a well-ventilated area. 
  3. Stir thoroughly to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
  4. Test for color & adhesion over existing sealed surfaces. 
  5. Thin as desired with distilled water; start with 5%, adding up to 10% by volume. 
  6. Increase open time, if needed, with 10-15% by volume of General Finishes Extender if allowed by local regulations. GF Extender will improve flow and leveling and increase open time, which is helpful in dry climates. California Residents: Adding more than 2% of GF Extender will make the products non-compliant per SCAQMD Regulations. GF assumes no liability for the improper use of these products.  
  7. Ready to spray from container. Wear NIOSH-approved respiratory and eye protection. 
    • Spray application: Before spraying, strain through a fine-mesh filter. Spray wet films at 3-5-mil thickness. Medium air cap. Compressed air: .040, HVLP: 1.1mm-1.3mm, Air-Assist Airless: 600 PSI pump, 20 PSI assist air, .011" tip or Airless: fine finish .007"-.011. Verify tip sizes with your equipment supplier. See our spray tip size recommendations here. 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 mask and work in a ventilated space. Read here for more information on spraying techniques.
    • Face frames: Enduro professional products are engineered to be spray-only but can be successfully applied successfully to cabinet face frames, edges or drawer fronts with a small cabinet-specific 3/8" nap microfiber roller such as Whizz or AllPro brand. Larger areas may not level with a roller application. Add 10-20% Extender for improved results. 
  8. If a faster build is desired over raw wood, use General Finishes Sanding Sealer for the first coat, followed by 2 coats of Clear Poly.
  9. Dry time based on ideal conditions: 70°F/21°C; 50% humidity. Tack free 5-10 minutes. Ready to sand 30-45 minutes. Recoat in 1-2 hours. Be sure to allow adequate dry time. You can tell if a water-based finish is dry if it forms a powder when lightly sanded with a 220-320 sanding sponge. If in doubt, wait longer. Rushing the dry time can cause "blush," which is clouding in the finish due to moisture trapped between the layers. Increase dry time if:
    • Higher humidity
    • Cooler temperatures
    • 3+ coats are applied
    • Thick coats are applied
    • Applying over a sealed surface
    • 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 accelerate dry time 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.
  10. Finish sand between coats with a 220-320 sanding sponge to improve smoothness and adhesion.
  11. Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.
  12. A topcoat is not required.

Tinting
We recommend using Colourfal Zero VOC colorants. Other colorant systems should be zero VOC, incorporated at the point of use, and tested thoroughly for performance before application. General Finishes will not be liable for in-can stability when other colorants are used.

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 completely cured. Treat gently, and do not clean with commercial products during the curing period.

Warning

Do not use water-based products with Linseed Oils or Danish Oils.

Dry Time

Dry Time Based on ideal conditions of 70°F 21°C; 50% humidity.  

To touch: 10+ minutes

Ready to Sand: 30-40 minutes

Recoat: 1-2 hours

Be sure to allow adequate dry time. 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 or 400-grit sandpaper. If in doubt, wait longer. Rushing the dry time can cause "blush," which is clouding in the finish due to moisture trapped between the layers.

Increase dry time if:

  • Humidity is over 80%
  • Temperatures are cooler.
  • 3+ coats are applied
  • Thick coats are applied
  • Applying over an existing sealed finish
  • 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 accelerate dry time 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.

Yellowing & Clear Topcoat

As is true of most "water-white" topcoats, General Finishes water-based topcoats dry clear over non-reactive substrates, such as plastic or metal, except General Finishes Enduro-Var, which ambers. When white paint sealed with a water-white topcoat is applied to something as unpredictable as wood, all bets are off and the reason for yellowing is often unknown. It can be caused by topcoat activating tannins in raw wood or aniline dyes, stains, or contaminants in a pre-existing finish. This is most evident when using BRIGHT WHITE paint and most prevalent in sculpted details of furniture where the topcoat can collect, intensifying color change to an unacceptable level.

There is no reliable way to predict whether yellowing will occur and to what degree. Every existing finish is different and we rarely know the finishing provenance on an existing piece. Every tree is different and every piece of wood is unique. Raw wood can bleed tannins immediately after the topcoat dries or months later with seasonal temperature changes. Oak, pine, mahogany, and Douglas fir are particularly prone to bleed-through.

Summary

  • Whites have a lower “hide” quality and are more transparent than most other colors. Nearly all bright whites require additional coats to achieve the desired color and minimize color variation. This can increase the cost of paint finishing. Always include a clause in your contracts addressing the need for additional coats to achieve coverage.
  • All bright white paint will yellow slightly with time, with or without topcoat. You have probably tried to touch up white woodwork in your home after several years and noticed the new paint is brighter.
  • The underlying finish or wood species can affect the final color of light paint.
  • Details and inside corners are difficult to cover with any paint color, but it tends to be more noticeable with whites. This is a naturally occurring phenomenon in paint application and does not necessarily constitute a defect in the paint finish or your technique.
  • The more porous the paint, such as a chalk paint, the more likely that yellowing will occur. The topcoat is seeping through the spaces caused by the larger particles of filler that give Chalk Paints their texture.

Tips to Prevent Yellowing

  • If it is a low-use project, use a premium white paint that is self-sealing and does not require a topcoat. A clear topcoat is not required on General Finishes Milk Paint for increased durability, as it is a self-sealing, exterior-rated coating with high durability and chemical and water resistance. However, topcoats do provide a smooth surface that is easier to clean and boosts durability for high-use projects, such as tabletops and kitchen cabinets.
  • Use a professional product such as General Finishes Enduro White Poly. It has "increased topcoat properties," is a standalone finish when 3 coats are applied, and does not require sealing with a topcoat.
  • We recommend using General Finishes Stain Blocker, an engineered chemical barrier, to prevent persistent bleed-through for interior-use projects.
    • Stain Blocker does not adhere to melamine cabinet veneers.
    • Stain Blocker cannot be tinted.
  • Always test your project's ENTIRE finishing schedule (from cleaning to topcoat) on an inside door or a more hidden area of the piece. This will not help if the yellowing occurs later, but at least you will know if there is an immediate problem.
  • Avoid painting period furniture, such as a 1940s serpentine mahogany desk, with light colors. The pieces were often finished in stain that contained aniline dyes, which cast a pinkish bleed-through under light paint. Not every piece of furniture is suitable for upcycling with a light paint color. Pine, mahogany, and furniture of the 1940s and 50s are a red flag.
  • Last, not all manufacturers' topcoats are compatible with other finishes and may react with a color change. Always follow best practices by not rushing, and testing to your satisfaction first.

Knots
Knots in wood tend to bleed and are dense, making paint and stain adhesion a challenge. Stain Blocker may improve adhesion and prevent bleed-through for painting projects. Pine knots are especially difficult to cover with white or light paints. If you decide to paint over them, apply 3 coats of Stain Blocker first; however, we cannot guarantee adhesion or bleed-through blockage. You are better off using a dark paint on pine.

Cleanup of Water Based Products

Application tools and materials containing water-based products can be cleaned with soap and water or General Finishes 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.

Disposal

Discard unused product and waste in an environmentally safe manner; check with local fire and health regulation. 

Storage of Water Based Products

Life of Product

General Finishes products do not last forever, even when unopened. They are best used within 1 year. The life of the product may be extended with proper can closure and storage conditions. (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. Settling is natural. Always stir thoroughly before using.

Foul Smell

If your product has a 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.

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. Product falling into 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 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.
  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 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.

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

DOWNLOAD SPRAY TIP CHART PDF 

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.

DOWNLOAD SPRAY TIP CHART PDF

This PDF lists general guidelines for several different types of sprayers with specific General Finishes product recommendations for HVLP listed below.

RECOMMENDED TIPS FOR GENERAL FINISHES PRODUCTS USING HVLP:

  • 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.

Yes! Enduro Clear Poly in Dead Flat can be tinted in the same way as other sheens. The color may be softer, but it can be done. 

As always, we recommend that you test on a hidden area of your project or a test board to make sure you are happy with the result before starting your project.

PROFESSIONAL TOPCOATS

ENDURO PRE CAT LACQUER (Spray only)

Looking for hardness, clarity and fast stack time? Pre Cat Lacquer is the choice. Use in applications where there is little risk of chemical contamination issues from substances such as ketchup, soap, chemical cleaners, or ammonia. This is the perfect spray finish for interior doors, casing, moldings, door jambs and furniture that receives light use. When you think about it, interior doors don't take a lot of wear. You might wipe them down or dust them once in a while but that is about it. PreCat Lacquer is a hard finish that provides excellent build and superior clarity at a phenomenal price point. If you are not finishing a surface such as a tabletop where you anticipate chemical contamination during use, why pay for a more expensive finish?

ENDURO CLEAR POLY (Spray only)

Poly is the go-to cabinet finish. It has all the durability you need at a lower price point than Conversion Varnish. It is similar to High Performance in test measurements for chemical, water and wear resistance, but HP can be brushed and Clear Poly can't - it is already thinned for spraying. Clear Poly has a bit of an edge over High Performance in overall chemical resistance, a 98 rating vs 92.

Varnish will cure the fastest. Requires NCO Catalyst. It is recommended for commercial applications or extremely high-wear surfaces such as countertops and bar tops

FLAT OUT FLAT (Brush or Spray)

Flat Out Flat is formulated with a self cross-linking acrylic, and is designed to mimic the look and feel of a wax finish. Because of the increased matting agents used to create the "Flat look", this finish will have less clarity. Like wax, it dries softer to the touch than High Performance when completely cured, and will show more fingerprints. FOF finish will mark up more easily because of increased matting agents used to reduce the sheen, so it is not recommended for high-use tabletops.

ENDURO-VAR II (Spray or brush)

Enduro-Var II is an oil modified water-based alternative for customers that want the warm look of an oil finish in a water based coating. It looks more like an oil finish than a water coating, and can be sprayed or brushed. The original Enduro-Var adheres well ONLY over WATER STAINS, DYE STAINS, and RAW WOOD. Use over other finishes at your own risk. The new formula of Enduro-Var II is compatible with all GF products and dries to a lighter amber than the previous formula.

It is suitable for vertical surfaces such as fences, patio furniture, garage doors, entrance doors, outdoor kitchens and interior windows. It is not recommended as a deck finish.

How do you maintain clarity of a Dead Flat sheen over dark colors?

Traditionally, flat topcoats were created by adding matting agents to gloss topcoat. These agents decreased the durability of the topcoat and produced a slight haze that reduced the vibrancy of an underlying stain or paint. 

Using newly patented polymer resin technology, matting agents are no longer required.  Our new Dead Flat topcoats produce a brilliant clear finish while providing significant improvements to chemical, water and mar resistance.

The new Dead Flat Matte sheen formula is available in the High Performance and Clear Poly lines. You can now achieve the look of our original Flat Out Flat while maintaining clarity and GF's high performance standards.

  • Both products can be sprayed.
  • High Performance can also be applied by hand with a foam/bristle brush.
  • Clear Poly and High Performance are both Urethane/Acrylic blends.

What makes GF's Dead Flat sheens different?

 

General Finishes Water Based Topcoat High Performance Dead FlatGeneral Finishes Water Based Topcoat Enduro Clear Poly Dead Flat

Until now, Matte sheens always came with a compromise in durability. Consumers have been asking for an ultra-flat topcoat that is as durable as our other sheens, and we are finally able to deliver!

Thanks to brand new patented polymer technology, we are now able to create a Matte sheen without waxes and matting agents that decrease durability.

Defining Durability
All of our testing shows High Performance Dead Flat is as durable as High Performance Satin, which is a drastic improvement over Flat Out Flat topcoat.

Flat: (degree sheen)
Flat Out Flat: <5
High Performance Dead Flat: <5

Water Resistance: (max 5)
Flat Out Flat: 2
High Performance, Dead Flat: 4

Chemical Resistance: (0-100)
Flat Out Flat: 82
High Performance, Dead Flat: 92

Scratch Resistance and Marring:
Scratch Resistance is strong with both products.
Marring is better than Flat Out Flat and comparable to the Satin and Flat.

High Performance vs. Clear Poly
The main differentiator between these products is that Clear Poly is a spray-only product and High Performance can be applied with a brush or sprayed. Clear Poly is popular among high production contractors but both products produce professional results.

Upgraded Features

  • Patented self-matting polyurethane
  • Uses renewable resources, with no Prop 65 chemicals
  • Meets KCMA standards
  • VOC compliant nationwide

Warning: Do Not Mix!
Topcoat with a Dead Flat sheen CAN NOT be mixed with another sheen because a completely different polymer is used and the combined formulas will not perform well as one.

  • Hard Wax Oil 

GENERAL PRACTICE:

  1. Oil-based topcoats and ENDURO-VAR II will amber over time.
  2. All other water-based 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 soap and water. Oil-based topcoats require mineral spirits for cleanup.
  5. 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.
  6. For more complex projects with many details and corners or large surface areas such as cabinets, we recommend either ARM-R-SEAL liquid oil-based topcoats or water-based topcoats. Large surfaces such as cabinets or tables and complex projects with lots of detail are easier to cover with a liquid topcoat rather than a GEL SATIN topcoat.
  7. Enduro Professional Topcoats are thinner and intended to be sprayed
  8. HIGH PERFORMANCE can be brushed or sprayed. It can be thinned by adding 5-10% distilled water if needed.
