Ensure that surfaces to be treated are clean, dry, and free from dust, dirt, loose debris, and any other surface contaminants. It is important that any wood preservative used beforehand does not contain wax, oil or silicon as these will reduce the ability for Cuprinol ducksback to adhere to the wood and reduce performance.

Bare or New Timber

1. Brush wooden surfaces with a stiff brush or broom to remove surface dirt, debris, mould, algae, and moss
2. Areas affected by mould, mildew, algae, and fungi should first be treated with a suitable garden cleaner
3. All rotten timber must be cut out and replaced
4. If the wood surface is looking worn or has greyed from sun damage and the effects of weathering, Cuprinol Garden Furniture Restorer can be used to revive the wood before coating
5. Any holes, gaps or splits in the surface of the wood can be filled with Cuprinol All Purpose Wood Filler or Cuprinol Ultra Tough Wood Filler
6. Bare or untreated garden wood can be pre-treated with Cuprinol Wood Preserver prior to painting if additional protection is required against insect attack, rot and decay.

Previously Coated Timber

• Cuprinol 5 Year Ducksback cannot be used over paints, varnishes or any surface coating / sealant.
• Any existing surface coatings such as these should be fully removed back to clean, bare wood, by sanding or using a suitable paint and varnish stripper

Can I use Cuprinol 5 year ducksback over other wood treatments?

It depends on the type of wood treatment previously used. If it's something like a wood preserver, or oil-based product that penetrates in to the surface of the timber, as long as the previous treatment was applied at least a year ago, Cuprinol Ducksback should be fine. We always recommend, however, that a small test area is done before starting any project to test adhesion and final finish. This product cannot be used on surfaces that are sealed with a wood paint or varnish.
