Denatured alcohol or lacquer thinner

Sponge brush or a Preval Sprayer

Color-Matched STAIN Coat:

  • Clean your cabinet surface before you start painting! The stain will take best to your dirt-free surface.
  • Use an even 1:1 mix of lacquer to lacquer thinner in your Preval sprayer.
  • Thinking of re-working a small section? Take our advice and retouch the entire piece of trim. It's easier.
  • Hold your Preval Sprayer about 6-10” away from the trim when spraying, unless you're working with a lacquer or quick-drying finish. 
  • As you know, stain can start a fire! Be mindful of any sparks or open flames near your work area. Keep your rags and stain containers in mind - and out-of-the-way - too.



  • See any flaking polyurethane on your soon-to-be-spruced-up surface? Lightly sand the area to remove the flaking.
  • Make sure to clean your surface thoroughly with a brush or vacuum.
  • Remove any nearby hardware. Or you can tape over it.
  • Tape vinyl windows and doorways too.
  • Thoroughly tip and stir your can of stain to mix the contents.
  • Time to pour the stain into the Preval bottle!  
  • Attach your Preval Sprayer to the bottle and screw it on snugly.
  • You're ready to go!



  • Pass the Preval Sprayer evenly over the area to be stained, only slightly past the edges. This helps avoid overspray!
  • Apply 2-3 light coats of stain to your surface.
  • Clean your Preval Sprayer by spraying through the unit with lacquer thinner.
  • Time for a well-deserved break! Your stain needs to dry overnight.
  • It's day 2! Continue by pouring MINWAX® or other lacquer with a matched gloss into your Preval spray bottle.
  • Now mix 1 part lacquer with 1 part lacquer thinner in your Preval bottle.
  • Keep your spray technique from yesterday! Time to apply three even coats of lacquer to your newly-stained area.
  • You've made it. Time to remove your tape and re-attach any hardware.
  • A quick spray through the Preval Sprayer with lacquer thinner will clean it out. It's ready to go for next time.
