DEFY Exterior Wood Stain Stripper is a ready-to-use liquid that quickly removes worn finishes to restore wood surfaces. Both water-based, and oil-based stains and varnishes are removed.


LIMITATIONS: DEFY Exterior Wood Stain Stripper is not designed to strip paint or other film-forming surface coatings.

SURFACE PREPARATION: Surfaces to be stripped must be above 50°F. Protect adjacent surfaces; cover with plastic sheets and/or tape off any adjacent areas not being stripped. Thoroughly wet and/or cover plants and shrubs. Rinsing residue will not harm plants or roots. Exposure to full strength product will burn foliage. Test area: Test product in a small, inconspicuous area to ensure desired results before general use.


  1. Shake well before use.
  2. Lightly dampen (not saturate) surfaces to be stripped to avoid excessive grain raising.
  3. Apply a generous and uniform coat with a polyester brush or pump-up sprayer. On vertical surfaces, apply product from bottom up to avoid streaking. Avoid application in direct sunlight.
  4. Allow DEFY Exterior Wood Stain Stripper to remain wet on a surface for 15 to 25 minutes. Reapply if drying occurs. Allow time for product to work.
  5. When finish begins to lift from wood surface, scrub if necessary with a stiff bristle brush in the direction of wood grain.
  6. Rinse in the direction of the wood grain with large amounts of water using highest pressure from a garden hose or power washer with 500- 1200 psi. Using a power washer will eliminate the need for scrubbing. However, particular care should be taken with a power washer to avoid damaging wood. Rinse adjacent areas at the same time.
  7. If stubborn areas remain, repeat the application in those areas.
  8. Neutralize and brighten wood with DEFY Wood Brightener immediately after stripping, or within one day. Any stripper not neutralized and thoroughly rinsed will cause poor coating adhesion.
  9. Allow wood to dry before refinishing.

Note: Product may darken cedar and redwood and raise the grain on some species of wood.

COVERAGE: 100-150 square feet per gallon depending on surface.
Cleanup: Clean tools & equipment immediately after each use with soap & water.
