    Always ensure the surface to be treated is clean, dry and free from any dust, algae, fungi or moss.

  • To clean wood give it a good brush with a stiff brush to remove any dirt, debris or loose wood
  • If the wood has been previously stained, painted or varnished, we would recommend to strip it back to the bare wood. For previously stained decking you can use Cuprinol’s Stain Stripper
  • If your wood has been effected by algae, fungi or moss this must be removed and can be cleaned with products such as Cuprinol Decking Cleaner or Cuprinol Garden Furniture Cleaner

  • Application

    Before applying stir the product thoroughly and test a small area to ensure colour and adhesion. Colours can vary dependant on surface to be treated.

  • Apply 2-3 coats evenly
  • Allow the previous coat to soak in before applying the next coat, usually 2-6 hours under normal weather conditions
  • Recoat within 2-3 days of previous coat
  • Apply only in dry conditions, above 5°C and when bad weather is not forecast
  • Colour in the can may be different to the final shade when dry
  • Avoiding splashing of surrounding plants, brickwork, glass, PVCu, etc. Any splashing should be cleaned up immediately
  • For a strong colour change more coats may be needed
  • If using more than one tin it’s advisable to mix together in a large container or finish in a corner before starting a new can to ensure consistency in colour
  • Note: Always follow the manufacturer instructions found on the tin.

    Aftercare & Storage

    To maintain your treated wood reapply a maintenance coat every year to prolong the life. Occasional cleaning with a dampened cloth or brush can also prolong the life of your treated wood.

    Store any remaining product in dry conditions and protect from frost and sunlight.
