Cuprinol is a product that protects, cleans, restores and preserves wood. Untreated wood loses colour, becomes unattractive, deteriorates quickly and can become unsafe. Whether you have a wooden fence, patio, trellis, building or outdoor furniture, Cuprinol is the best bet to preserve and enhance the wood's beauty. Cuprinol is available in 23 different shades.

    Pre-Treat Wood Cuprinol Preservative

  1. 1

    Using a firm-bristled brush, remove any dirt or debris from all bare wood.

  2. 2

    Use a putty knife to remove any algae, moss or other growth from the wood.

  3. 3

    Use a brush to apply a fungicidal wash, such as Dulux Trade Weathershield Multi-Surface Fungicidal Wash, to all affected areas to remove any remaining algae, fungi, moss or lichen.

  4. 4

    Allow the fungicidal wash to remain on the wood for at least 24 hours.

  5. 5

    Rinse and scrub off the fungicidal wash with a brush and clean water.

  6. 6

    Allow the wood to dry completely before pre-treating with Curpinol Trade Low Odor Wood Preserver Clear.

  7. 7

    Brush on a single coat of Cuprinol Trade Low Odor Wood Preserver Clear to prevent decay.

    Apply Cuprinol Timbercare

  1. 1

    Cover your hands and eyes with gloves and protective eyewear.

  2. 2

    Stir Cuprinol Timbercare thoroughly with a wooden stir stick. Re-stir occasionally as you work.

  3. 3

    Use a clean, dry paint brush to apply Cuprinol Timbercare to an area to test colour and adhesiveness. Like paint, the colour may differ from the colour in the container when dry.

  4. 4

    Use a paint brush to brush on Cuprinol Timbercare in smooth strokes, going with the grain of wood.

  5. 5

    Allow the wood to dry for two to six hours. Depending on the wood, a second coat may be necessary.

  • Do not apply Cuprinol Timbercare when temperatures are below 5 degrees C, in damp or humid conditions, or if rain is in the forecast.
  • Use a Cuprinol sprayer for fast, convenient application.
  • Cover your hands and eyes with gloves and protective eyewear prior to using cleaning, preserving or colouring substances.
