Before applying stain, all raw wood projects require preparation sanding. If you skip this critical step, your finish may fail.

Preparation 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.

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.

General Finishes Dye Stain Application Steps

1. Watch product overview video here
2. Test your entire finishing schedule first. Dye Stain is like ink, and once you apply it, there is no going back as it will sink like ink into the pores of the wood. Stain color can be affected by variances in wood, room lighting, and deepened with the application of a topcoat. 
3. Stir stain to reincorporate solids that have settled to the bottom of the can before and throughout the application process.
4. Increase open time, if needed, with up to 5% General Finishes Extender, if allowed by local regulations. 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 product non-compliant per SCAQMD Regulations. GF assumes no liability for the improper use of these products. 
5. An initial coat of General Finishes Pre-Stain Conditioner Natural can improve color uniformity over difficult-to-stain wood species such as pine. However, it will limit color absorption and reduce blotchiness, so a darker stain may be required to get the depth of color you want.
6. NOTES on softwoods such as Pine, Pawlonia, or Poplar, the use of Pre-Stain Conditioner will reduce blotchiness but not remove it entirely. You may want to consider using GF's Wood Stain instead. And also regarding softwoods, an alternative technique instead of using Pre-Stain Conditioner is to add 10% High Performance to the Dye Stain. This will add enough solids to even out the finish and will lock in the color to reduce color pull when you apply the first clear coat. 
7. Divide your project into manageable sections: top, side, drawer, door, table seam.
8. Apply 1-2 coats. A second coat will create a deeper, richer color. Do not apply more than 2 coats.
   • Hand application: Apply a LIBERAL amount of dye stain using a cloth, a synthetic bristle brush, foam brush, pad applicator or roller.  Use a light touch with the brush - just flood the surface without dragging the applicator. Dye Stain penetrates the surface fast; if not enough stain is used, the surface may dry too quickly, causing an uneven appearance. Stain one complete section, such as a side, top, or drawer, and immediately wipe off excess evenly with a cloth, paper or shop towel before starting the next section.
   • 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 work in a ventilated space. 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 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. Visit this FAQ for more information on spraying techniques.
   • If you will be using GF Conversion Varnish as a topcoat, seal first with either GF Sanding Sealer or Clear Poly before spraying Conversion Varnish. This will minimize the reaction from the dye and catalyst.
9. Dry 2+ hours between coats in ideal conditions: 70°F/20°C; 50-70% humidity. Inadequate dry time is one of the top reasons for finish failure. If in doubt, wait longer. Increase dry time if humidity is over 80%
   • Increase dry time if two coats are used.
   • Increase dry time if humidity is over 80%
   • o accelerate 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.
10. Allow final coat to dry 2-4 hours in ideal conditions: 50-70% humidity, 70°F/20°C.
11. Finish with 3 coats of General Finishes topcoat.
12. If you will be using GF Conversion Varnish as a topcoat, seal first with either GF Sanding Sealer or Clear Poly before spraying Conversion Varnish. This will minimize the reaction from the dye and catalyst.

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

Always seal General Finishes Water Based Wood Stain, General Finishes Dye Stain and General Finishes Enduro Ready-To-Match (RTM) Water Based Wood Stain with 3 coats of topcoat. More coats will not improve durability.

Grain Raise

After the first coat of topcoat has dried, you can knock down grain raise by lightly sanding with a 220 sanding pad. Watch Grain Raise video here.

Recommended Water-Based Topcoats
General Finishes High Performance can be applied by hand or sprayed; General Finishes Enduro Clear Poly is spray-only. Both topcoats dry clear and are great for high-use surfaces, such as kitchen cabinets and tabletops. General Finishes Flat Out Flat is our flattest topcoat, suitable for projects that do not receive major wear.

Recommended Oil-Based Topcoats
When sealing with General Finishes oil-based topcoats, General Finishes Arm-R-Seal and General Finishes Gel Topcoat, let water-based stain dry a minimum of 24 hours first. Oil-based topcoats amber increasingly over time.

Toning is the process of adding colorant (tinting), 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 GF water-based stains can be used: Stock base colors of RTM stains, Water-Based Wood Stains or Dye stains. If you are new to toning, we recommend starting with GF 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.

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).

Custom Colors using Dye Stain Reducer
Create custom color Dye Stains by adding General Finishes Dye Stain Reducer in 10% increments until you achieve the color you want. It is not possible to mix too much of our Dye Stain or Reducer together. Do NOT Use Water to Lighten General Finishes Dye Stains. Dye Stain Reducer has ingredients that help keep color molecules dispersed evenly in the can. 

Layering Dye Stain
Use Dye Stains to highlight the depth of the grain, to even out color saturation, and to achieve deeper colors under other stain applications. Example: Use Amber or Yellow Dye Stain for a golden glow under General Finishes Gel Stain or General Finishes Water Based Wood Stain.

Toning
Dye Stains can be used as a toner when mixed with water-based topcoat. A 10-20% stain to topcoat ratio is recommended for a slight color change. 

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.

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. However, the life of the product may be extended several more years 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
