Can I thin General Finishes EF Water Based Stains?

Thin GF water based stains with distilled water if desired. Start with 5%, adding up to 10% by volume. 
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.

GF Enduro RTM stains are a thinner formula designed for professional spray applications.

*How Do I Prevent Bleed Through When Applying Whitewash Over Espresso Water Based Wood Stain?

Water Based Stains will always exhibit a bit of bleed through. When glazing with any color over water stains, we recommend some type of seal coat is applied first.

Unfortunately, the two colors you have chosen do not work very well together. Expresso will always bleed if Whitewash is applied directly over top. In the future, seal the Espresso stain with a coat of Shellac, and then General Finishes High Performance Topcoat. Allow both to dry, then apply Whitewash as a glaze (1 part stain, 1 part topcoat mix).

Here are two remedies we recommend to fix for bleeding that has occurred:

  1. Strip away finish and start over. 
    Stain with Espresso, top with Shellac, and then with 1-2 coats High Performance. After the HIgh Performance has dried, apply the Whitewash as a glaze (1:1 stain & HPTC). Seal with High Performance.
  2. Paint over the bleeding stain. 
    Seal current finish with Shellac and then paint with Seagull Gray Milk Paint.

Any time you apply a light stain over a dark stain there is a possibility of bleed through. Therefore, it's important to seal off the base color first. 
If the look of the wood grain is not important, Dark Chocolate Milk Paint is an exact match to Java Gel Stain when painted, and it could be used as an alternative base color.

Why can't I get a dark stain color on Maple wood using water based wood stain over pre-stain conditioner?

Maple is one of the most difficult woods to achieve a dark, uniform stain color on because it is a dense, closed grain wood and often absorbs stain very unevenly. General Finishes Gel Stains or Water Based Stains usually will perform very well because they are more topical than traditional liquid oil stains, and contain more colorants. 

We do not recommend pre-sealing Maple with a conditioner because it closes up the grain of the wood even more, further preventing color adherence. In the future, just use our water-based stains or gel stains on their own. Do not use liquid oil-based stains on Maple because they will blotch.

Also, prep sand Maple with 120 grit, followed by 150 grit or 220 grit.

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.

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.

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.

*Can I Use Interior Wood Stains Outdoors If I Coat With an Exterior Topcoat?

Interior wood stains are formulated for interior use and do not contain UV absorbers, mold retardants or HALS (Hindered amine light stabilizers used to protect the polymers from the effects of photo-oxidation.) Waterbased interior stains are much more likely to fail.

You could try this look on an exterior door that will not receive a lot of sun, but be prepared for more maintenance than usual. It is not recommended.

Everyone should note that all exterior finishes need to be maintained at some point - MOTHER NATURE wins the longevity war
