The following steps and products are required.

  • All surfaces must be clean, dry and free of any dirt, oil and grease.

  • Scuff sand any glossy surfaces. If making repairs, use stainless steel or galvanized nails to prevent nail staining. Countersink nail heads, repair imperfections and sand smooth. Remove all dust with a damp cloth and allow to dry.

  • New and Weathered Wood: Use a product such as KILZ Wood Cleaner & Brightener to open wood pores for better penetration and remove any mill glaze and mildew stains. Remove remaining wood fibres and debris by sanding lightly.

  • Painted Wood Surfaces: To strip previous coating, use a product such as KILZ Wood Stain & Finish Stripper. Then clean and neutralize with a product such as KILZ Wood Cleaner & Brightener.

  • After using KILZ Wood Cleaner & Brighter or KILZ Wood Stain & Finish Stripper, rinse thoroughly with a garden hose or pressure washer. When rinsing with a pressure washer, use the broadest spray pattern while keeping the nozzle at least 0.6 m away from the surface. Allow the area to dry at least 24 hours before coating. Lightly sand to remove remaining wood fibers/fuzz.

WARNING! Sanding or scraping pressure treated lumber may be hazardous; wear appropriate protection.


  • Avoid applying in direct sunlight or to hot surfaces.

  • Must apply between 4.5°C - 32°C. Do not use if rain is expected within 24 hours.

  • The wood surface must be completely dry before application.

  • Intermix multiple containers to ensure colour uniformity. DO NOT DILUTE. Stir product occasionally throughout application.

  • Test product for penetration and colour on a small hidden area before proceeding.

  • Use a nylon/polyester brush for areas requiring more accuracy. Use of rollers should be limited to rough surfaces only. Use 10 mm nap or longer when appropriate.

  • A high quality pump sprayer with a variable tip or an airless sprayer with a .015"-.019" tip (60 mesh filter recommended) may be used.

  • Work in small sections lightly saturating the surface and immediately back-brush or use pad applicator to eliminate puddling, remove excess and evenly distribute the finish. Maintain a wet edge when applying.
