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 Woodhttps://www.youtube.com/watch?v=Tl4s34DZolc&t=3s

  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 RTM Water Based Stain

General Finishes RTM Stain.  Stain Application Steps 

  1. Watch how to color match RTM stain here https://www.youtube.com/watch?v=F-Mnr_UjGec&t=1s
  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%, adding 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.
  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, so a darker stain may be required to get the depth of color you want.
  6. Test your complete finishing process before starting. The stain color is affected by variances in wood and deepened with the application of topcoat.
  7. Divide your project into manageable sections: top, side, drawer, door, table seam.
  8. Hand-Application over Raw Wood:
    • Apply a LIBERAL amount of stain to ensure easy workability using a synthetic bristle brush, foam brush, pad applicator, staining pad or microfiber roller. If not enough stain is used, the surface may dry too quickly, causing an uneven appearance. On large projects, leave a wet edge between sections to prevent lap lines.
    • Stain a complete section and 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 details with a synthetic bristle brush.
    • Let the stain dry 2-4 hours in ideal conditions: 50-70% humidity, 70*F/20*C. Be sure to allow adequate dry time. If in doubt, wait longer. Increase dry time if:
      • Humidity is over 80%
      • 3+ coats are applied (not recommended)
      • Thick coats are applied
      • Working over a previously existing finish
        • To accelerate dry time in humid conditions, add General Finishes Accelerator 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.
    • Optional: apply a second coat to deepen the color. Apply no more than 2 coats.
    • Finish with 3 coats of General Finishes topcoat.
  9. Spray Application over Raw Wood: 
    • HVLP: 0.9mm-1.1mm spray tip, medium air cap. Verify tip sizes with your equipment supplier. See our spray tip size recommendations here. 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 25-50% for even coverage.
    • Read here for more information on spraying techniques.
    • Apply section by section. Spray liberally to a complete section and 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 the stain because they will “push” the stain around and not absorb it.https://www.youtube.com/watch?v=F-Mnr_UjGec&t=1s
