The following steps and products are required.

  • Be sure to have a source for water, hose with nozzle and stiff bristle broom or brush and a neutralizer/conditioner such as KILZ Wood Cleaner & Brightener.

  • Do not apply in direct sunlight or on hot surfaces.

  • Dampen nearby foliage with water and cover with plastic drop cloths.

  • Wear protective clothing, goggles, acid resistant gloves, and NIOSH-approved respirator.

  • Conduct a small test patch in an inconspicuous area to ensure product performance.

  • Prevent all rinse solution from entering storm drains.



  • For best results, apply when air and surface temperatures are between 10°C - 32°C.

  • Pour KILZ Wood Stain & Finish Stripper directly onto surface and apply liberally using a nylon/polyester brush or roller. Natural bristle brushes or lambswool applicators are not recommended.

  • DO NOT USE PUMP SPRAYER. Due to product thickness, paint or other sprayers will clog tip.

  • Always keep surface wet by misting with water and re-apply product if drying occurs.

  • Finish will begin to lift from the surface. Repeat process as needed to keep the surface wet during the removal period. Most deteriorated finishes will start to lift after about 5-45 minutes. When the finish starts to lift, scrub the surface using a stiff bristle broom or brush.

  • Rinse thoroughly with water from garden hose using nozzle at normal pressure, or use a pressure washer at a low setting 500-1200 PSI. DO NOT USE HIGH PRESSURE as this may harm the wood. If some of the old finish remains on the surface, repeat application procedure or spot sand as needed.

  • Follow up with a product such as KILZ Wood Cleaner & Brightener to remove stains, rejuvenate natural wood colour and to neutralize the stripping action.

  • COVERAGE:  4.6 m² - 14 m².
