Dulux Trade Aqua Uniprimer

Dulux Trade Aqua UniPrimer is a high-performance, fast-drying, water-based primer designed for superior adhesion on all major interior and exterior surfaces. Ideal for wood, metal, uPVC, and even glossy pre-painted finishes, it penetrates porous substrates, seals surfaces, and effectively blocks tough stains such as water, nicotine, grease, and tannin bleed. This versatile primer also inhibits rust and delivers excellent opacity, doubling as an undercoat for a smooth, professional finish.

To get the best results, ensure surfaces to be painted are sound, clean and dry (new surfaces particularly must be fully dry) and free from all defective or poorly adhering material such as efflorescence, dirt, grease or wax. For bare metal surfaces, pretreatment is recommended to ensure good adhesion. Soak a sanding pad in a mild alkaline cleaning solution and lightly abrade on bare metal. Leave for 10 minutes and lightly abrade again. Rinse thoroughly with clean water and allow the surface to dry well before applying Dulux Trade Aqua UniPrimer.

Stir thoroughly before use. After suitable preparation, apply one coat of Dulux Trade Aqua UniPrimer, followed by the appropriate Dulux Trade paint system. This product does not require thinning for brush and roller application. For spray application thin 20% for HVLP and up to 5% for Airless.

Do not use or store in extreme temperatures and protect from frost. Store upright with lid tightly closed.

Q. What makes Dulux Trade Aqua UniPrimer different from a standard primer?

A: Dulux Trade Aqua UniPrimer is a multi-purpose, one-can solution that not only primes and seals, but also blocks stains (like water, nicotine, grease, and tannin bleed) and prevents rust on metal—making it a true all-in-one prep product.

Q. Do I need to thin the Dulux Trade Aqua UniPrimer before application?

A: No thinning is required when applying with a brush or roller—the product is ready to use straight from the tin. However, for spray application, thinning is recommended: up to 20% with water for HVLP sprayers and up to 5% for airless spray systems to ensure smooth and even coverage.

Q. Can Aqua UniPrimer be used as an undercoat?

A: Yes, its high-opacity and smooth finish allow it to double as an undercoat, providing a clean, even base for topcoats.

Q. How should I prepare bare metal surfaces before using Dulux Trade Aqua UniPrimer?

A: To prepare bare metal surfaces, it is recommended to soak a sanding pad in a mild alkaline solution, lightly abrade, wait 10 minutes, abrade again, then rinse with clean water and allow to dry fully before priming.

Q. Can I apply the primer to new surfaces straight away?

A: New surfaces must be completely dry before applying Aqua UniPrimer. Painting on damp substrates can lead to poor adhesion and long-term issues.
