                              Instructions

                              Step 1: Preparation of Raw Wood for Water Based Stain

                              Before applying stain, all raw wood projects require preparation sanding, and all existing finishes require prep cleaning and sanding.?If you skip this critical step, your finish may fail.

                              Prep?Sanding for Raw Wood Projects
                              See our video: How to Prep Sand Raw Wood

                              1. Sand open-grain wood?(e.g., oak, ash, mahogany, parawood) with 120-grit sandpaper, followed by 150-grit, then 180-grit.
                              2. Sand closed-grain wood (e.g., cherry, pine, maple, birch, alder) with 150-grit sandpaper followed by 220-grit.
                              3. Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.
                              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.

                              Prep?Sanding for Existing Finish

                              1. Remove any existing finish by sanding with 120-grit-sandpaper & scuffing with a wire brush if needed.?
                              2. Remove dust with a vacuum, compressed air, an oil-free tack cloth or a water-dampened rag.

                              Reducing Grain Raise on Raw Wood
                              To reduce grain raise, dampen the wood with water after prep sanding. Let dry completely, then lightly sand with fine-grade (220-320) foam sanding pad.

                              Step 2: How To Apply General Finishes Exterior 450 Stain

                              General Finishes Exterior 450 Water Based Wood Stain Application Steps

                              NOTE: Exterior 450 stain is not intended for decks. It can be used on tabletops that do not receive direct exposure to sun and rain. As with all fine furniture finishes, wipe up spills in a timely manner to protect the finish.

                              1. Watch 450 Exterior Stain overview video here.
                              2. Stir stain to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
                              3. Thin?as desired with distilled water; start with 5%, increase up to 10% by volume.?
                              4. 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. ? ?
                              5. Test your complete finishing process before starting. Stain?color is affected by variances in wood and deepened by the application of topcoat.
                              6. Divide your project into manageable sections: top, side, drawer, door, table seam.
                              7. Hand-Application Over Raw Wood:
                                • Apply a LIBERAL amount of stain to ensure easy workability using a synthetic?bristle brush, foam brush, pad applicator?or short-nap roller. If not enough stain is used, the surface may dry too quickly, causing an uneven appearance. On large projects, leave wet edge between sections to prevent lap lines between sections.
                                • Wipe off the excess evenly with the grain using quality paper towel or shop towel. Check for missed spots and lap marks before moving to the next section. Do NOT use cotton t-shirts to wipe away stain because they will "push" the stain around and not absorb it.
                                • Immediately correct lap marks by rewetting the entire working area with stain and wiping off the excess.
                                • Pull excess stain out of corners and detail with a synthetic bristle brush.
                                • Let the stain dry 2+ hours?when applying 1 coat in ideal conditions, 70°F/20°C, 50-70% humidity. Increase dry time if:
                                  • Humidity is over 80%
                                  • A second coat is applied
                                  • Thick coats are applied
                                    • To accelerate drying in humid conditions add General Finishes Accelerator to?Exterior 450 Stain before applying and work in a space with good ventilation and air movement. If you decide to re-coat before the recommended time, test dryness.?
                              8. 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. Wear a full filter respirator (NIOSH/MSHA-approved)?and, if spraying in an interior space, make sure there is good ventilation.?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 50%?for even coverage. Wipe back the excess with an absorbent cloth.?Read here for more?information on spraying techniques.
                                • Let the stain dry 2+ hours in ideal conditions (50-70% humidity, 70*F). Increase dry time if:
                                  • Humidity is over 80%
                                  • Additional coats are applied
                                  • Thick coats are applied
                                    • To accelerate drying in humid conditions add General Finishes Accelerator to?Exterior 450 Stain before applying and work in a space with good ventilation and air movement. If you decide to re-coat before the recommended time, test dryness.?
                              9. Optional: apply a second coat to deepen the color. Apply?no more than 2 coats.
                              10. Finish with 3 coats of General Finishes Exterior 450 Topcoat.

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

                              Step 3: Topcoat Over Exterior 450 Stain

                              Always seal General Finishes Exterior 450 Stain?with 3 coats exterior-rated topcoat. We recommend?General Finishes Exterior 450 Topcoat, which?is formulated to be compatible with Exterior 450 Stain.

                              Exterior 450 topcoat and stain are not intended for decks. It can be used on tabletops that do not receive direct exposure to sun and rain. As with all fine furniture finishes, wipe up spills in a timely manner to protect the finish.

                              Exterior 450 Topcoat is designed to allow water permeate the finish and, as it dries, the water releases back out to allow the finish to tighten down again.?

                              Horizontal surfaces and uncured surfaces with sitting water may cloud or blush temporarily as the finish dries. Once fully cured, any blushing that occurs should be minimal.

                              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

                              Most dyes, such as Trans Tint, can only be mixed with alcohol or water, not mineral spirits. A water-based?finish, such as Exterior 450, cannot be used in conjunction with mineral spirits, even with an extended dry time. Solvents?do not play well with water-based finishes.

                              Unfortunately, there is no fix for the peeling finish. You will have to sand the project down, apply an exterior stain and recoat with Exterior 450. Also, advise your customer that no finish will withstand the sun indefinitely. All exterior finishes need recoating and maintenance?over time.

                              Should I use Pre-Stain Conditioner Before Staining a Douglas Fir Door to prevent blotching?

                              Douglas Fir is a difficult wood to stain evenly.?A 50|50 mix of your Exterior 450 stain color and Exterior 450 Clear would be a better choice for an exterior conditioner.?Blotching may still occur even with this procedure.

                              After applying the conditioner mix, let it dry 2-3 hours. Allow more time in humid weather. Then a apply the stain color of your choice. Multiple coats will deepen the color.

                              What is toning finishes?

                              General Finishes Dye Stain

                              Toning is the process of adding colorant, either dye or pigmented stain into a top coat and then applying over an entire piece in order to subtly deepen the color. All of our stains can be used: Stock base colors of RTM, Water-Based Wood Stains or Dye stains. If you are new to toning, we recommend starting with Dyes stains, which can be easier to use as they only contain dyes and no pigments.?

                              All of General Finishes water-based topcoats with the exception of Conversion Vanish?can be tinted to create lightly colored finishes for toning. ?It is?YOUR RESPONSIBILITY TO TEST?to your satisfaction before application to your entire project.?

                              You can also tone with Gel Stains - see these?videos:?

                              There are?limits anytime you add pigments or dyes to water-based topcoats. Toning should always be done in small increments to achieve the desired color. If you are starting with a light honey tone door and you want to create an Espresso color this will take multiple coats of color including base coat of stain followed by several toning coats. It is impossible to achieve a radical change in color in coat application.

                              A good rule to follow when tinting is starting with a minimal amount of stain or dye, 5-10% by volume. Some colors work better than others. Normally 1-2 ounces or stain per quart of clear topcoat is sufficient to create a toner. Always test color first and strain material through a fine mesh filter to remove any undissolved particle of pigment. Once you have achieved the desired color tone apply a clear topcoat to lock in 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).

                              General Finishes Oil Based Topcoats

                              • Arm-R-Seal?
                              • Gel Satin Topcoat
                              • Wood Bowl Finish
                              • Butcher Block Oil
                              • Outdoor Oil

                              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. 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. Large surfaces such as cabinets or tables and complex projects with lots of detail are easier to cover with liquid topcoat rather than a Gel top coat.
                              8. Enduro Professional Topcoats 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 5-10% distilled water.?
