General Finishes Enduro Professional Topcoat Application Steps
Stir topcoat to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
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 increase durability.
- 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 mask and work in a ventilated space. Read here for more information on spraying techniques.
- Face frames on cabinets: Enduro professional products are engineered to be spray-only but can be successfully applied to cabinet face frames or edges with a pad or small, cabinet-specific roller, such as Padco NanoFlock Roller. Larger areas may not level with a hand application. Alternative: Use the same sheen of General Finishes High Performance Topcoat on areas that must be brushed.
If a faster build is desired over raw wood, use General Finishes Sanding Sealer for the first coat, followed by 2 coats of Enduro Clear Poly Topcoat.
Dry 2+ hours between coats in ideal conditions: 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 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.
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.
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.
Cleanup of Water Based Products
Application tools and materials containing water-based products can be cleaned with soap and water immediately after use.
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.
Life of Product
Water-based products do not last forever, even when unopened. 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.
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.
Water-based finishes crystalise 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 10°C or above 26°C. Keep from freezing. Frozen and heat-damaged product cannot be revitalised. 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:
- 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.
- Mixtures involving colours & 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
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 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 lustre.
- 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.
