FAQs

How often do I need to reapply Cuprinol 5 Year Ducksback?

This product is designed to provide 5 years of weather protection. For continuous protection and best appearance, reapplication is recommended approximately every five years, or sooner if you notice signs of wear or fading.

Can I use this product on smooth planed wood or decking?

No, Cuprinol 5 Year Ducksback is specifically formulated for rough sawn timber like fences and sheds. It is not recommended for smooth planed wood, decking, or garden furniture, or any surfaces that receive foot traffic.

Do I need to use a primer or base coat?

No, a separate primer or base coat is not typically required. Ensure the wood surface is clean, dry, and free from loose material before direct application of Cuprinol 5 Year Ducksback.

How much area does a 9L tin cover?

Each litre covers approximately 5 square meters. Therefore, a 9L tin will cover up to 45 square meters, depending on the porosity of the wood and the number of coats applied.

What tools are needed for application?

You can apply Cuprinol 5 Year Ducksback using a good quality exterior wood brush or a roller. Ensure tools are clean before use and cleaned thoroughly with water after use.

Can I apply this over existing paint or stain?

For best results, it's recommended to apply to bare or previously treated rough sawn timber. If applying over existing coatings, ensure they are compatible, clean, sound, and not flaking. Always perform a patch test.

Is this product safe for pets or plants once dry?

Once dry, the product is generally considered safe for pets and plants. However, always prevent pets and children from accessing treated areas until fully dry. Avoid contact with plants during application.

Troubleshooting

Uneven color or patchy finish

Ensure the product is thoroughly stirred before and during application. Apply evenly and consistently. For rougher timber, use a brush to work the product into the grain.

Paint not drying within 2-4 hours

Check ambient temperature and humidity. Drying times can extend in cold or damp conditions. Ensure thin, even coats are applied. Avoid applying too thickly.

Poor coverage or product runs

Ensure the surface is clean and dry. Apply thinner coats to avoid runs. If applying to very absorbent wood, it may soak in faster, requiring more product initially.

Product peeling or flaking after application

This often indicates poor surface preparation. Ensure all loose material, dirt, and old flaking paint/stains were removed prior to application. The surface must be clean and dry.

Color appears different than expected

Colors can vary slightly depending on the wood type and its original color. Always perform a patch test on an inconspicuous area of your timber before full application to confirm the desired color.

Setup, Compatibility & Care

Before You Begin

  1. Preparation: Ensure the wood surface is clean, dry, and free from dirt, algae, or loose flakes of previous coatings. Use a stiff brush or appropriate timber cleaner if necessary.
  2. Stirring: Stir the contents thoroughly before and during use to ensure consistent color and performance. Do not dilute.
  3. Patch Test: Always test a small, inconspicuous area first to check color and adhesion.

Application Steps

  1. Tools: Apply using a brush or roller. For best results, use a quality exterior wood brush.
  2. Coats: Apply 2-3 even coats, allowing 2-4 hours drying time between coats. For optimal protection, ensure all end grain is thoroughly treated.
  3. Temperature: Apply in dry conditions, ideally when temperatures are between 5°C and 30°C. Avoid applying in direct sunlight or if rain is expected.

Compatibility

  • This product is specifically designed for exterior rough sawn timber, such as garden fences, sheds, and other similar wooden structures.
  • It is not recommended for smooth planed timber, decking, garden furniture, or surfaces that receive foot traffic.
  • Do not apply over surfaces previously treated with paint, varnish, or other non-porous coatings, as adhesion may be compromised.

Care & Maintenance

  • Cleaning: Periodically clean treated surfaces with a soft brush and water to remove dirt and maintain appearance. Avoid harsh chemicals.
  • Re-application: For continued 5-year protection, re-apply the treatment after approximately five years, or sooner if signs of wear or fading appear, especially in high-exposure areas.
  • Storage: Store in a cool, dry place, away from frost and direct sunlight. Keep containers tightly closed when not in use.
