Application Method

REAL PERFORMANCE. Use & Preparation.

EXPERT’s Wood Brightener is STEP 2 of our 3-STEP system. Intended for use on all types of weathered wood, including decks, fences, siding, log homes, patio furniture and other exterior wood.

EXPERT’s Wood Brightener is ideal for surface prep prior to stain application. Product can be used solely as a cleaner and brightener, or as a neutralizer to further brighten woods that have been previously cleaned or stripped.

TEST AREA: It’s recommended to test this product in a small, inconspicuous area to ensure desired results before use. Raised grain can occur as wood pores are opened during the cleaning process.

LIMITATIONS: EXPERT Clean & Bright Wood Brightener cannot remove intact paint, stain, or clear finishes, and may dull painted or metal surfaces if not rinsed immediately. Always store in a temperature-controlled room, kept from freezing, and can be stored for up to 36 months, unopened.

REAL APPLICATION. Easy-to-Use & Clean-Up.

Read through all the step-by-step instructions prior to using EXPERT®™ Clean & Bright Wood Brightener.

MIXING: Always wear heavy-duty rubber gloves, niosh approved respirator and PPE when working with EXPERT Clean & Bright Wood Brightener, or any other EXPERT Clean & Bright products. Mix 4oz to 8oz of Wood Brightener with each gallon of warm water and stir thoroughly until powder is mostly dissolved. Mix in a separate 5-gallon pail before transferring into a pump sprayer. This avoids clogging the sprayer. Use Brightener solution within 24 hours of mixing.  Wood Brightener mixed solution is colorless for ease of identification.

APPLICATION: Thoroughly wet the treatment surface, and all surrounding areas, including plants and shrubs with water before application. Apply EXPERT Clean & Bright Wood Brightener solution using either the sprayer, or a brush, a car wash brush, or mop. Scrubbing is not needed after using EXPERT’s Cleaner or Stripper. Let the Brightener solution sit for 5 to 15 minutes, keeping it wet with additional solution until an obvious color change has occurred.

If applying Brightener on vertical surfaces, begin at the bottom, working upwards. Repeat application, if needed.

RINSE: Rinse surfaces and surrounding areas thoroughly for 20 to 30 minutes with water from a hose or pressure washer using lowest pressure. Rinse wood and surrounding surfaces thoroughly, never let solution dry on windows, siding, metal and other surfaces or residue may be visible.

Allow wood surfaces to dry 48 to 72 hours (or longer) before applying EXPERT Stain & Seal wood stains. Stains must be applied when wood is dried to 13% moisture content or less.
