                              Flat Out Flat Water Based Topcoat

                              Flat Out Flat is a self-crosslinking?water-based topcoat that mimics?the lustrous look and feel of wax. The increased matting agents used to create? "flat look" cause this wood finish to have less clarity, show fingerprints more and provide slightly less durability than High Performance. It is recommended for low-use projects other than kitchen cabinets and table tops.

                              Step 2: How To Apply General Finishes Flat Out Flat

                              CAUTION:?Do NOT use GF Flat Out Flat?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 Flat Out Flat Application Steps

                              1. Watch product overview video here.
                              2. Stir topcoat to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
                              3. Apply 3 coats. More coats will not improve durability.
                              4. Thin as desired with distilled water; start with 5%, increase up to 10% by volume.?
                              5. Increase open time, if needed, with up to 5%?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.
                              6. No more than 3 coats are?recommended. Flat Out Flat contains more matting agents to decrease the sheen, and the finish can get cloudy when excessive topcoats are applied.
                                • Hand application: Apply a liberal amount of product using a synthetic bristle brush, foam brush, pad applicator, or roller. Avoid pressure and excessive back-brushing.
                                • 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.
                              7. If a faster build is desired over raw wood, use General Finishes Sanding Sealer for?the first coat, followed by 2 coats of Flat Out Flat.
                              8. Dry 2+ hours between coats in ideal conditions: 70°F/20°C; 50-70% humidity.?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. 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%
                                • 3+ coats are applied
                                • Thick coats are applied
                                • Applying over a previously existing 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.
                              9. Finish sand between coats with a fine-grade (220-320) foam sanding pad to improve smoothness and adhesion.
                              10. Remove dust with a vacuum, oil-free tack cloth or clean water-dampened rag before re-coating.

                              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 during the curing period.

                              Tips to prevent streaking during hand-application
                              See our video: How to Prevent Streaking with Water Based Topcoat

                              • To avoid streaking, apply a liberal amount of product and?avoid using pressure and back-brushing. Wipe the wood grain using smooth, even strokes. Use a large applicator, such as a paint pad, for larger surfaces.
                              • Remove streaks by buffing with?or fine-grade (220-320) sanding pad, or sanding well and re-coating.
                              • For the smoothest result, apply with a spray gun.

                              Mixing Topcoats
                              Do not mix Flat Out Flat and High Performance topcoats. They are engineered with different resin systems.?

                              Use

                              • Flat Out flat is not recommended for high-use areas such as cabinets and tabletops. The popular flat sheens are lovely, but they have different properties than glossy finishes. The flatting agents required to reduce sheen in matte topcoats also slightly reduce clarity, water resistance, durability and resistance to chemicals such as ketchup, soap, chemical cleaners or ammonia. This is not much of a concern in low-use areas but is important for tabletops or kitchen cabinets.
                              • Here is a tip to improve the performance of your finish and still obtain a matte sheen:?Use a semi-gloss sheen for the first 2 coats and a flat for the third for optimum performance.?
                              • Or instead use High Performance Water Based Topcoat or Arm-R-Seal Oil Based Topcoat.

                              ?

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

                              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 spray 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 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

                              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 of the manufacture date listed on the can.?However, the life of the product may be extended 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?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.
                              • 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.

                              Flat Out Flat FAQs

                              What is the difference between Flat Out Flat and High Performance Topcoats?

                              Flat Out Flat is a matte water based topcoat with a velvety feel and was developed as a durable alternative to our Satin Wax. Choose this product if you want a finish that looks more like wax and your project will not require high use. Like wax, it dries softer to the touch than High Performance when completely cured, and it will show more marring and fingerprints. Flat Out Flat is made with a stable self cross-linking acrylic instead of urethane.
                              High Performance is urethane based and contains less matting agents which result in a slightly harder finish. For that reason, High Performance is the best choice for high use areas such as table tops and kitchen cabinets. Both topcoats have similar water resistance, but High Performance offers greater clarity. ?
                              Use with Oil Based Finishes: Let oil-based finishes dry for 72 hours before applying High Performance or Flat Out Flat top coat.?

                              *Can I Mix General Finishes Flat Out Flat and High Performance Topcoat?

                              No, you should not mix Flat Out Flat and High Performance?topcoats. They are engineered with different resin systems.

                              You can mix High Performance topcoats to adjust sheen. For example, you can mix HP Flat and HP gloss to obtain a different sheen.

                              What is the best way to obtain a more durable finish with a flat sheen?

                              The popular flat sheens are lovely but they have different attributes than glossy finishes. The flatting agents required to reduce sheen in flat or matte topcoats also slightly reduce clarity, water resistance, durability and resistance to chemicals such as ketchup, soap, chemical cleaners, or ammonia. This is not much of a concern in low use areas but is important for table tops or kitchen cabinets.

                              Here is a tip to improve the performance of your finish and still obtain a matte sheen:?
                              Use a semi-gloss sheen for the first two coats and a flat for the third for optimum performance.?
                              ?
                              General Finishes is constantly seeking new resins and additives to improve the performance of our finishes.

                              *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.

                              *Which Is Better as a Sealer? Topcoat or Wax?

                              It depends on whether you are looking for aesthetics or durability.

                              A topcoat will provide greater durability and protection than wax finishes over time.

                              While wax finishes are lovely, they typically show wear (fingerprints) and are not permanent, requiring semi-annual to annual maintenance.

                              Wax is a low durability finish. It’s fine for a decorative piece that will receive light traffic. It is absolutely not strong enough for tables, kitchen cabinets, or other surfaces that will see frequent use. ?

                              Wax takes a bit of elbow grease to apply.

                              Furthermore, nothing adheres well to wax, which can impact future finish changes. Even though there is internet chatter about removing wax with 3rd party products or mineral spirits, the risk of a failure in re-coating over a wax finish is very high and sometimes impossible.

                              If you love a wax finish, try General Finishes Satin Finishing Wax. If you want the look and feel of wax with more durability, use our General Finishes Flat Out Flat Topcoat. For even more protection, use General Finishes High Performance Topcoat.
