Cuprinol 5 Year Ducksback 5L

Cuprinol 5 Year Ducksback is a water-based, non-drip wood treatment for garden sheds, fences and other rough sawn timbers. Enriched with wax for a water-repellent finish that forces moisture to run off the surface like a duck's back.

Ensure that surfaces to be treated are clean, dry and free from dust, dirt, loose debris and any other surface contaminants.

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 a suitable, wax-free clear wood preservative prior to painting if required

Please Note It is important that any wood preservative used does not contain wax, oil or silicon as these will penetrate the wood and repel any water-based product that is applied on top.

Previously Coated Timber

Cuprinol 5 Year Ducksback cannot be used over paints, varnishes or any surface coating / sealant.

• Any existing surface coatings such as paints, stains and varnishes must be fully removed back to clean, bare wood, by sanding or using a suitable wood stripper

Always do a test area before starting any project to test adhesion and final finish. Follow the manufacturer's instructions on the tin at all times.

Do not apply in temperatures below 5°C, in damp conditions or if rain is likely before the product has dried. Stir thoroughly before and periodically during application.

1. Apply 2-3 coats of Cuprinol Ducksback evenly along the wood grain, avoiding overlaps
2. Allow 2-4 hours between coats under normal drying conditions
3. Where a strong colour change is involved, more coats may be required
4. Recoat within 2-3 days of previous coat. If a longer period elapses try a test area to ensure product is not repelled

Surfaces treated with Cuprinol Ducksback can be cleaned at regular intervals with a dampened, lint-free cloth or Cuprinol Garden Furniture Cleaner.

Maintenance

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

A. 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.

If treating a garden shed or fence that has been previously coloured or stained with a pigmented wood preserver or other penetrative wood treatment, its worth noting that the old colour could influence the final colour of the Ducksback weatherproof treatment. Always do a test area first.

Q. Can I use Cuprinol 5 year Ducksback on wooden garden furniture?
