The following steps and products are required.

  • All surfaces must be clean, sound, 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, 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 & Brightener 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.


  • 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.

  • Avoid applying in direct sunlight or to hot surfaces. DO NOT DILUTE. Intermix multiple containers to ensure colour uniformity. Stir product occasionally throughout application. Use a 10 mm nap roller, nylon/polyester brush, pad applicator or airless sprayer.

  • Airless spray is recommended for experienced applicators only; use a .015"-.019" tip (60 mesh filter for airless spray recommended). If thinning is required, thin with water at a rate of no more than 0.25 L per 3.79 L.

  • Maintain a wet edge when applying. Always back-brush and apply product end to end or to board lengths to prevent lap marks.

  • Over application of stain will lead to surface failure including peeling and cracking. Avoid applying stain too heavily. Two thin coats recommended. For optimum performance, coat all accessible sides.

  • COVERAGE: 1st Coat 23 m² - 28 m²; 2nd Coat 46 m² - 56 m².
