Strip Stubborn Paint
Step 1: Set Up
If working with a door, remove it from its hinges and place on sawhorse in a well-ventilated work area. If possible, keep work surface horizontal. Remove all hardware from the door, including knobs, lock, and hinges. If the door has inset glass, carefully tape off the glass before you begin.
Pour the KS-3 Premium Stripper into the metal container. Lay all of your tools nearby.
Step 2: Lay it on thick
Brush an even, liberal coat of stripper to a small area (up to 9 sq. ft.) The correct application is not like painting. Instead, you want to apply it at least 1/8" thick, so the stripper covers the old paint. Use short strokes in one direction only. Make sure to use the tip of your brush to work the stripper into the recesses of the wood.
Step 3: Check progress and remove paint
After 15-30 minutes, you should start to see the chemical reaction happening. The paint will start to bubble up and swell, and this will show that the finish is separating itself from the surface. Gently rub a small test area with the plastic stripping tool to see if the finish is softened and ready for removal. If not, wait an additional 15 minutes and check again.
Step 4: Remove the stripper and the paint comes with it
Remove loosened paint by gently scraping in direction of wood grain with the plastic stripping tool. Reapply stripper as necessary to keep the surface wet. Use the orange stick or stripping brush to scrape out old finish buried in recesses. Continue to alternately scrape, reapply stripper, and wipe with cloths as you progress.
Repeat as necessary. Multiple layers of paint may require several applications. There is no need to remove all stripper before starting a second application. Simply re-wet the working area and continue to let the old paint "soak" in the stripper.
Step 5: Finish up
By now, you should be seeing the fresh, clean surface emerging from beneath all that old finish. Use a clean abrasive pad dipped in KS-3 Premium Stripper to loosen remaining finish and remove any residue.
When the wood looks clean and clear of all finish, wipe off the stripper using an abrasive pad dipped in Klean-Strip Paint Stripper After Wash or Klean-Strip Odorless Mineral Spirits. The wood surface should be completely clean and dry before refinishing. Return unused stripper to the original container.
After each work session, place all rags, applicators, and old-finish residue in a well-ventilated area. Allow liquid to evaporate and residue to dry outdoors then dispose of in accordance with federal, state and local regulations.
